The following lines need fixing before anything will run: Line 3 should read in part- Q$ =CHRS(34) [not QS+CHRS (34)1 Line 5 should read in part- DestfileS [not DestfilesS] Line *8 should read in part- Flength&;“:READ XS etc. ["", not Incidentally, the more adventurous programmers are probably aware that not all of the Bmap file is needed if only a few library functions are being accessed. You take the file apart and keep only the register information that pertains to the specific functions used.

Experience has taught its that this sort of tenacity is the norm for Amiga users. If perfection continues to be the goal of users, the A miga com munity will go a long way.
Track Hack Dear Editor, Like all good hacks, the “Trackball” (August 1988) can be improved. After buying the trackball (the hardest part), I realized that I wished to use it as a mouse and a joystick. Instead of making the cuts on the pc board, I pulled the ic A5 (4019) from its socket. Pins 1, 3, 5 and 7 of the 4019 were bent out, and the tc was inserted back into its socket. (Pins 1, 3, 5 and 7 do not stick into the socket.) The 4019 is CMOS, so one has to take the standard precautions. Pin 1 was then connected to Point C (Fig. 1) using wire-wrap wire and a low-heat soldering iron.
Similarly, pin 3 was connected to Point D, pin 5 to Point A, and pin 7 to Point B. Replacing the cable went according to the instructions in the article except the colors of the wires differed. Now the Atari trackball can be used as an Amiga mouse or joystick at the flip on the built-in switch. I wonder what Jack T. thinks of this?
Yours sincerely, Wesley Ebisuzaki Connecticut Track Hack II Dear AX.
I am writing in reference to the TrackMouse hardware article that appeared in the V3.8 copy of Amazing Computing. There was an error in the wiring instructions on page 36. Mr. Joyce indicated that the right trackball button be connected to the yellow wire of the joystick cable. He also mentioned that the gray wire was not needed, but that it could be connected to the right trackball without ill effect.
In actuality, the gray wire needs to be connected to the right trackball button, and the yellow wire is not needed. The confusion might have arisen from the fact that in the Amiga 1000 User Guide, Commodore lists Mouse Button *2 as pin out 5 (yellow wire) and Mouse Button 3 as pin out 9 (gray wire). The right button on the Amiga mouse is Mouse Button 3!
Aside from this problem, the modification went fine. I would like to tell Mr. Joyce that I (being somewhat of a novice) decided to solder the “trace” connections to the chip socket pins (chip A5), as I could not solder to the traces on the board. I did have to use a meter to determine which socket pins to do the soldering to.
Lastly, I would like to thank you for continuing to run the hardware projects.
This is the second one I have completed for my Amiga, and I look forward to more (perhaps a fix that will allow 1000 owners to use the new graphics chip set?). Keep up the good work.
George Houghton Indiana Thanks to all for living up to the tradition of true hacking.
Dear Amazing Computing, I'm just writing to tell you guys what a great job you are doing with your magazine. It is truly one of the best AMIGA magazines along with INFO magazine. In the August issue of your magazine, Graham Kinsey asked anyone who knows the backdoor to ARKANOID to write him. Weil, here it is.
1. Pause the game with the space bar.
2. Type “dsimagic” (not the quotes) and press return.
3. Unpause the game by hitting the space bar.
4. If you did everything correctly, a capsule with the letters DS
on it will fall from the top of the screen, catch it.
5. Now, you can call up any capsule by hitting its initial.
Ex, L for Laser, C for catch, B for break etc... You can also skip screens by hitting the enter key.
You can go to the final screen by hitting F.
6. In this mode, you can have normally incompatible capsules
Ex. You can disrupt the ball and use lasers too.
By the way, I read about this back door from INFO magazine issue 19- Steve Kee Canada For all youfrustratred Arkanoid freaks out there, brick-breaking success is only a backdoor away.
Speedy Startup Dear Amazing Computing, Over the past few months, I have been looking for ways to speed up my stanup- sequence. Here are some time-saving tips I have been using that others might find useful:
- Use the full path name of commands and files rather than
searching (set by the PATH command) through the directories for
them. For example, instead of: COPY FORMAT TO RAM Use:
SYS:C COPY SYSSYSTEM FORMAT TO RAM: A new release from Lattice
who brought you the better C OBJECT ORIENTED. A FIRST FOR YOUR

An end to the high price of ink-jet ink editorial corner. Is AC too technical, not technical enough, or somewhere in between? Please let us know what you think. Remember, as readers, you make the editorial decisions.
- When printing multiple lines on the screen, instead of using

Inky dink is velvety rich and smooth satisfying the most discriminating palette.

- If a directory, such as SYSTEM, exists on your disk, do not
bother to search for it. Just add that directory to die
existing path.
- If you have enough memory, use the ADDBUFFERS command. I find
that adding 25 buffers to dfO: speeds things up considerably.
- If you wish to execute files from your startup-sequence, make
your current directory RAM: before executing the file.
This makes the T Command work file be created in RAM:.
Here is a sample Startup-Sequence: SYS: C ADDBUFFERS DFO: 25 ;adds 25 buffers to dfO:, uses approx, I2.5K SYS;C MAKEDIR RAM:C SYS:C PATH ADD RAM:C ;Searches RAM:C for commands first.

I hope these tips make booting up your Amiga a little more speedy.
Sincerely, Mark E. DelCogliano New York
P. S. I think Amazing Computing is great.
I especially like your columns THE COMMAND LINE and C NOTES FROM THE C GROUP, and the technical nature of you magazine. Keep up the good work.
Your speedy startup alterations are appreciated. In your “P.S., "you bring up a point that is always buzzing in the AC Galileo Gaffe Dear AC, In the introduction to the Amiga Product Guide, Education Edition, you asked for notice of any omissions. Well, I found one glaring omission which I felt I must point out.
Under the science section on page 62, my program, Galileo 2 was not mentioned. Considering Galileo has consistently received glowing reviews, and won title as "most Innovative Educational Program" at the Chicago CES, I was surprised that it was not included. Instead the Microillusions program, Planetarium, was listed, even though it has been advertised for a year now, and never shipped. Galileo has been out for nearly 1 1 2 years.

You can be sure Galileo will be listed in our Amazing Product Guide: Winter '89.

co-founder Michelle Mehterian is the Corporate Secretary

original shareholders and executives have, on the other
hand, moved on for various reasons. Your other comments
regarding the buy out of the company and marketing staff
are false and misleading.
Aegis has changed dramatically this year, but for the better. Over the past three months, we have released three new products, Lights! Camera! Action!, Modeler 3D, and Aegis Draw 2000.
During the next three months we will release five additional Amiga products (as well as a new product line for the Macintosh II). That will bring our catalog of Amiga products to 20.- I have learned that I am not alone in reading misinformation published by your magazine. I hereby demand an immediate retraction of all false and misleading statements to be published in your next issue.
Sincerely, David Barrett President, CEO Aegis Development, Inc. As always, if readers have problems or corrections in regard to oar editorial content, they need only write us and we will publish their responses. In this vain, we have printed your response in full. To the best of my knowledge no “false or misleading statement” which has been brought to our attention in writing has ever gone unanswered. We continuously publish corrections in the largest format possible because we take our position at AC very seriously. We are a resource that the Amiga community can depend on.
As you are aware, there is a great deal of controversy from the Amiga community on the value of “ROOMERS." From the initial response to our letters column in the October issue of Amazing Computing (including many phone calls), the readers are for it, and the developers are against it. (Although this letter is the only written dissension we have received from a developer.) Our current position on “ROOMERS" remains firm; we will print the column with a disclaimer, and publish conflicting reports and responses as quickly and thouroughly as we are able.
Let me say that the mention of Aegis was small, and that it did end favorably.
There was balance to the piece, and a positive statement as to Aegis's position.
No attempt was made to discredit your efforts to increase your company's profitability. We are on your side.
Everyone at AC is extremely supportive of any developer who wishes to create products for the Amiga. However, our support must continuously be weighed with the longer view of protecting the Amiga user.
Roomers Rambles Dear Amazing Computing: I have been an avid reader of your publication for well over a year. I have always looked forward to reading about new software and hardware being developed for the Amiga. In addition, I have enjoyed reading about new technologies and new markets being opened because of the Amiga. However, the Vol. 3 No. 9 issue seemed to be two- faced.
In one section, I read about an exciting recent AmiExpo show where many new products were shown and announced.
Commodore’s presence seemed very reassuring. And the large turnout seemed to reflect die increased enthusiasm for the machine. And while I was reading this, I kept thinking to myself, “ Terrific!
Way to go!"
But a few pages later, I find myself reading a “Roomers” column that seemed intent on chilling the hearts and minds of each and every Amiga owner. Does this Bandito fellow actually believe that Apple has enough clout to, in one swift stroke, halt all of the momentum the Amiga has been gaining over the past three years? No way! If Apple plans on giving the Amiga some serious competition, I say “Fine!” It just may give Commodore more incentive to come out with their new computers and enhancements. Despite this scary column, I see no reason to believe that Commodore will not continue to beat them
with their new hardware boasting superior technology at less cost as diey have always done.
I can’t believe the Bandito really believes the 65816 chip is superior to the 68000.
(Gee, maybe if I turbocharge my Commodore 64's 6510 CPU, I can outperform a Mac li...) My point is to just worry about what is going to happen with the Amiga and forget about looking over our shoulders at Apple. After all. It's what the competition has been doing to Commodore for years now, isn’t it?
Sincerely, Robert E. Wilson California Roomers Rambles Dear AC: I just read the Roomers column in Vol.3 No. 9 issue.
It looks like Bandito is trying to push a square peg in a round hole. Does he really believe anyone but died in the woo! Apple H loyalists will put down $ 2500 for an 8-bit machine?
The 6502 was a good microprocessor in it’s time, but even pushing it to 7 Mhz, it’s not the wonder chip he makes it out to be.
He fluffs off multi-tasking because of the high costs of memory chips. I think even Commodore doesn’t know the convenience and ease of use you get with multi-tasking. I would never buy another computer without it.
For less than the $ 2500 system price he quotes for the Apple II GS Plus, I have an Amiga 1000 with 1 3 4 meg of RAM.

Even in the fickle, short attention-spanned world of video games, the cliche holds true. A Few years back, the coin-op classic Space Invaders blasted its way into bars and bowling alleys everywhere. Zapping rows of wiggling aliens became a quarter-gulping addiction and spawned a phenomenon called video gaming. Today's video arcades show how fast that phenomenon has grown up, but Space
Invaders clones keep popping up and luring new addicts.
The latest Space Invaders spin-off for the Amiga is the bluntly tided Better Dead Than Alien, developed by England's Electra Software and distributed in the U.S. by Discovery Software. Incidentally, Electra is tied to Oxford Digital, crafters of Hunt for Red October and Trivial Pursuit (remember that one?).
The premise, gun down waves of aliens, is familiar, but Better Dead scraps the similarities after that. You step into the moon boots of Brad Zoom, a James Bond-a-like determined to zap all enemies. At risk here is not only the universe, but according to Electra, your lunch as well.
The mutant aliens, “tire most revolting forms ever to pollute the universe," are a far cry from the friendly bop-a-longs of the original Space Invaders. In all their grotesqueness, these guys make the unsavory characters of other spin-offs (such as Galaga and Galaxian) look like lady bugs. Bleeeach! And for you wiseacres out there, the floating heads in the photo of die tide screen aren't the revolting aliens; they're the notably-better-looking designers of the game!
Along with varying degrees of ugliness, the mutants also possess different levels of toughness. Some mutants drop after a single hit, while others remain dangerous under fire. If you can bear to take aim on uglies widi glowing green eyes, extra combat power, freedom of movement, and other goodies are in it for you. Lively sound, multi- level action, and a Brad Zoom comic add to the battle. And if you can't stomach it alone, a simultaneous two-player mode is available.

V.I.P, another great “Discovery," helps you foil and frustrate the real demons of the computing world: viruses!
If you've been lucky enough to miss the irreparable vandalism of viruses, you may not know just how damaging these things can be. Viruses are invisible programs that latch onto a disk’s boot block and wipe out all the crucial information contained in SOFTWARE VIRUS INFECTION DISCOVER that block. Worse yet, viruses are more catchy than the common cold. Transfer of the virus from disk to disk is definite and undetectable. A single infected disk can corrupt every bit of information it comes in contact with. Last year’s SCA virus told us, “Your Amiga Is Alive!,” but this harmless-looking screen
message mercilessly translated to “Your Data Is Dead.” With V.I.P., short for Virus Infection Protection, Discovery Software has robbed a favorite credo from the Surgeon General: Prevention is the best medicine. Rather than simply sniffing out viruses, V.I.P. puts your boot block data away for safe keeping long before viruses come slinking along. V.I.P. grabs boots blocks from the files you indicate and packs that information away in a virus-free database. So if a virus slips into your files, all you need to do is get rid of the the virus-damaged files and replace them with your pristine
V.I.P, backups.
Like any good doctor, V.I.P also keeps an eye out for viruses that try to sneak in and attack. The Examine command acts as a standard virus checker, So if you suspect you’ve contracted a bug, V.I.P. can check the suspect block against the safely data- based block.
A deficiency inherent to vims checkers, though, is that they can only recognize viruses they've been programmed to nab. What about new viruses those being diabolically developed right now even as you innocently type in your valuable bits of data? No problem for V.I.P. If you come across a vims the program does not recognize, you can "teach" V.I.P. to pick out that vims. Just add the vims to
V. I.P.'s library, and the next time that vims shows up, V.I.P
recognizes it as a varmint. V.I.P. currently cuffs the six
most-unwanted viruses: SCA, Byte Bandit, Byte Warrior,
Obelisk, North Star, and Revenge.
Discovery Software, themselves players in the international market, also realize that viruses unlike huge trade deficits, “Freddy" movies, and boring Presidential campaigns are not exclusively American problems. V.I.P. tosses nationalistic pomp aside and operates in English, German, French, Spanish and Italian.
Viruses, fun bits of prankish programming for some, mean disaster for the rest of us. The problem is big, and getting bigger (even big enough to snag a Time magazine cover story in September). Protect yourself now.

Enough serious stuff. Anybody know the most direct route back
to some plain ole' fun? How about a comic book?
Everybody reads comics in the Sunday paper, on the editorial page just to broad jump over the mental potholes of a day in the real world.
Gold Disk's Comic Setter lets you create your own professional quality comics whenever you need a personal chuckle. Comic Setter goes way beyond personal use, too. Rainbowed, comic-set newsletters, advertisements, and other documents are bound to bash boredom, raise eyebrows, and roust results.
The program joins advanced graphic layout tools and standard comic book dements to come up with an easy- to-use fun factory. You can plop any number of any-sized panels on standardsized pages, along with speech "balloons,” cartoonish characters, and comic- style backgrounds. The panels you slap down are automatically masked together and clipped to fit. Multiple magnification settings let work with the full page or just a detailed scrap, and an adjustable grid eases layout pain.
According to Gold Disk, even if you “can’t draw,” you can create your own characters and backgrounds. If you, like me, are convinced that stick figures are artistic as you'll ever get, you can pick from a packed file of ready-made goons, good guys, and original scenes.
You can also import bitmapped IFF files from other programs.
If you dare to create, you’ve got 16 colors in interlaced hi-res or square- pixel, medium res in your art bag. Your tools include an airbrush with adjustable “spray distance” and “ink flow,’’ a plentiful mix of line weights and colors, and horizontal and vertical flipping.
Rectangles, ellipses, polygons, and Bezier curves are also supported.
To go along with Comic Setter, Gold Disk has also released the first modules in the Comic Art data disk series. Dual-disk sets of Funny Figures, Super Heroes, and Sci-Fi stuff are now available to add some zap, bam, and kaboom to your comics, Comic Setter - $ 99 Gold Disk

strikes at the ¦weirdest times. As a writer, I’ve been yanked
from sleep, dinner, meetings, and countless other situations
by ideas that “just couldn’t wait.’’ Diernar Development is
out to solve this dilemma for musicians with MidiVU. A
multi-tasking musical scratch pad for the Amiga.
MidiVU is a desk accesory that records any single track from a MIDI instrument in real time and allows tracks to be saved to disk. The program steals little memory, so it can be tucked away in all your programs for moments of inspiration. If a symphony pops into your head while you are creating an masterpiece in a drawing program or composing a novel with a word processor, MidiVU is at your melodious disposal. Record, Stop, Play, and Loop are the only commands you need.
MidiVU includes a pop-up MIDI Monitor that lets you keep an eye on all messages zipping through the MIDI port.
With this option, you can leam the ins and outs of MIDI and catch connection and data problems. The MIDI 1.0 message definitions are 3lso attached to accompanying help screens, and a menu option affords MIDI message filtering, MidiVU - $ 29 Diemar Development 12814 landale St. Studio City, CA 91604-1351 818-762-0804 A 3D Bridge With the release of Modeler 3D, Aegis Development has added some "depth’’ to the Amiga's trip into the third dimension. This new 3D object generation program lets you create everything from simple spheres and boxes all the way up through pinpoint, CAD-like designs.
Modeler, though, does not live by creation alone.
Modeler's biggest plus is its friendly dealings with so many existing software packages. Data from Aegis Draw, Draw Plus, and Draw 2000 can be imported and graduated to 3D with a click of the Exude function. The transformed object, just like any Modeler- created object, is then open to addition of points, polygons, colors, and shading.
Sculpt 3D and VideoScape 3D creations can also be imported and deftly edited.
To be fair, the manipulative Modeler is also manipulable. Exports spring to life through Aegis’s animation package, VideoScape 3D, and can then be molded as parts of animation sequences. Drawing an on-screen path and setting the number of ‘’tweens” of movement even allows Modeler to take its own camera and object motion files along to Videoscape. With enough memory (1 meg, that is), you can eliminate the in-between step by ainning VideoScape and Modeler simultaneously.
You can also save Modeler objects in Draw Plus or Draw 2000 format for CAD- style plotting in those partner programs.
As a creation tool, Modeler 3D provides top, front, and side view Projection windows for “true to the eye” accuracy. You can also check out objects in solid form for an overall view as you make changes. Multiple layers eight, in all let you isolate chunks of complex objects for individual work, and you can zoom in and our for close-up creation.
Accuracy is taken even further, to another “dimension” you might say, by a numeric coordinate display and grid snap that allow precise point placement. An on-screen toolbox lets you grab any of these tools anytime.
Menu options simplify tedious operations to mouse clicks. Functions such as Mirror and Array erase useless object duplication steps. Cylinders, planes, boxes, spheres and other 3D primitives are created automatically with menu options. You can shave set-up time by mapping out screen preferences and saving them for later use. Steps necessary' for reshaping and assembling primitives into complex objects are neatly taken care of by handy Modify commands. With commands like these, Modeler makes sure you've got plenty of time for the real fun behind 3D!

REVIEWS Meet Modeler by Da vid Hopkins I remember my first
look at VideoScape. The program was impressive, to say the
least. A 3-D rendering animation package that was easy to
operate and produced some incredible animations. It only had
one major flaw objects had to be laboriously mapped out on
graph paper and then typed into a text file. I don’t know
about you, but math isn’t one of my better subjects. The last
thing I want to do is spend hours over a hot piece of graph
paper! And then I heard about... ...Modeler 3-D, the little
beauty that would allow anybody to sit down at the Amiga and
draw out an object. No more typing in endless streams of
coordinates. Modeler would do all of that. It would also
generate spheres, cones, and all the things Vide- oScape's EGG
and OCT utilities could do. Modeler, though, would add a real
user interface and an undo! Wow!!
Aegis no doubt grew weary of my constant questioning. Where is it7 Where is it? Finally, they gave in. I visited Aegis for a showing of VideoScape 2.0, but they broke down and shotved Modeler to me.
My whole life flashed before my eyes. It was wonderful! I watched as the Aegis rep loaded the F15 jet object from VideoScape, grabbed a wing, and flipped it around.
“When?” I asked. "Soon," he answered.
It's shipping!
My hopes dropped when, a couple of weeks later, the same rep said that Modeler had been placed on temporary hold for some major changes. Would Aegis earn a spot in the list of Vaporware Software Announcers?
Well, guess what? Modeler is now reality, shipping as you read this. And I suppose you want to know about it, right?
Oh, alright, you talked me into it!
A New Vieiv Modeler 3D centers around the standard three view setup. The main screen, the “Projection Window," has these three views with a gadget beween them. Dragging that gadget around allows you to rearrange the views so they are as big or small as needed.
A bunch of other gadgets surround these views, so let's take a closer look.
Modeler 3D centers around the standard three view setup.
Lots of Gadgets Along the right side of the Projection Window is a whole string of gadgets. PNT displays the number of points selected at any one time. Immediately below PNT is the POL gadget, which divulges that same information about polygons. An edit box allows you to select a piece of an object for further editing (which comes later).
The next gadget, Scissors, cuts things out Cyou may have guessed). A little “Ghostbuster” symbol below is a sort of “master delete.” It deletes anything you select with the edit box; if you do not select anything, it clears the entire page. The next gadget is a curve tool (it looks more like jagged lines) that allows you to draw out connected polygons.
The triangle-shaped tool below uses points you specify to create a polygon. Below that tool is a gadget with two dots and an arrow. After selecting a point or points with the edit gadget, clicking this gadget allows you to point to another place in the 3D view and relocate the point(s) to that place. This provides one way to re-shape an object.
A set of arrows on the next gadget allows you to scroll around in each view.
Yes, there is an undo...or maybe I should say, an incredible undo gadget. How many programs let you switch between function screens and still undo a mistake on the first screea5 The lower left comer of the Projection Window contains a box that shows a scale. Clicking this brings up XYZ coordinates for more accurate placing. Also in the lower left comer is a small padlock, the Lock Plane gadget. A point is created by clicking in two different views. Selecting the same points independently later gets difficult. Locking a plane, for example, lets you say that points from a certain point on are
all on the X=0 axis. Simply clicking on the point in one of the other windows selects it. Sounds like a waste, but it comes in very handy.
Down in the lower right comer is one of the most useful gadgets a simple set of the numbers 1 through 8. Each number is a seperate page to work on.
Clicking on a number takes you to that page.
Wbat a Selection!
Modeler's menus begin with the usual Project menu containing the Load and Save options. Aegis was kind enough to provide the ability to load not only VideoScape 3D objects, but also Sculpt 3D scenes and drawings created with Aegis Draw Plus. Save allows objects to be saved in standard text mode, new binary mode, or as a motion fife. That’s right, a camera or object motion can be created by simply drawing it!
The Edit menu has the expected Cut and Paste commands, but it also contains a couple of other handy features. Once an edit box has been placed around an object, the Select option highlights the points or polygons it’s your choice. You can set the polygon color with the Set Color option, a point-and-dick chart of colors and attributes (such as matte, glossy, transparent). Polygons can also be flipped or sub-divided here.
The Display menu contains zoom features, as well as a screen selector.
Available screens include the already- mentioned Projection window, a 2D screen called a Template, and regular and color previews. The preview modes allow an object to be viewed with it's polygons filled, rather than wire-framed.
Rotation around the object is done by clicking around it with the mouse.
Modeler can also operate in any of three resolutions: standard interlace screen, a non-interlace screen, or the memory- conserving Workbench screen.
Modeler’s Generate menu is basically a reworked version of the old EGG, Easy Geometry Generator. Spheres, planes, boxes, tubes, etc., can be created on any layer. Lathe and Extrude are also available here. The Lathe option tosses you into the Template screen, where the curve tool is used to define a 2D shape.
Selecting Do Lathe causes Modeler to ask for the number of rotations and which axis to rotate the object around. Voila! A smooth, rounded custom shape is generated!
The Modify menu allows you to rotate, scale, mirror, relocate, etc. and object. Also found here is Remap, which allows an object to be twisted around any axis. Strange effects often result from that one! Finally, an Array option allows duplicate copies of an object to be made on other layers, each offset a specified amount.
Dag 'nabbW The only real problems I find with Modeler center around personal preference. One quirk is the way polygons are selected. An edit box can be placed around the polygon, or a venex of the polygon as selected in POL mode.
Unfortunately, this also selects a few surrounding polygons with it. Sure, they can be de-selected (kind of a hassle), but it would be much nicer to be able to click on the center of a polygon to select just that polygon. A solution might be holding down shift and clicking on other polygons that need the same change or color.
Next, while most of the abilities of EGG and OCT (Object Composition Tool) have been incorporated into Modeler, some important things have been left out. Fractal patches and stars are no longer options; both were handy to have around.
Is it ivorth it?
Perhaps the best way to illustrate the difference Modeler can make is the following situation. Aegis is preparing another demonstration videotape and some animations to be released on disk, and i was asked to contribute a few.
Within two weeks, I created seven animations that you should be seeing soon. This task would have taken much longer if hand-mapping were required.
In fact, Allen Hastings, author of VideoScape, tells me that he has switched entirely to using Modeler. This switch from a man who mapped over 500 points for a Lotus automobile by hand!
Over all... Modeler makes VideoScape an even better package. True, they aren’t packaged together, but they are defi- nately a perfect couple. Modeler sells for 599-95 and is an excellent investment for anyone interested in simplifying Vide- oScape's object creation process.

* AC- AMAZING R E V I AproDraw Graphics Tablet Will it be the
Amiga graphics tablet of the future?
By Keith Conforti AC Art Director The Amiga & The Artist The Amiga is a fantastic graphics machine, so powerful that it could tempt artists to drop pad and palette and pick up pixels and points. The major obstacle preventing the Amiga from becoming the standard in design and graphics are its input devices, all of which have been less than perfect simulations of natural freehand drawing. The devices’s main weakness is controlling color and pixel placement. The relative movements of the mouse and the tablet’s insensitivity and inaccuracy have discouraged many would-be Amiga artists.
The Amiga & The Artists’ Hardware Software and hardware developers realize the problems in this area and have concentrated much effort into producing better and better input devices for Amiga graphics.
One of the latest introductions is a series of graphics tablets developed by SummaGraphics Corporation of Stamford, Connecticut and distributed by R&DL Productions of Long Island City, New York. R&DL currently has two tablets available for the Amiga AProCAD and AproDraw, the subject of this review.
The AproDraw package includes the tablet, stylus, software tablet driver, a power supply, an optional four- button cursor or puck (for $ 50), and all the cables you need to get the tablet up and running, it hooks up to your Amiga via the serial port. If you use the tablet on a 1000, you’ll need a gender changer. In hooking it up to a 2000,1 noticed a slight disturbance the developers overlooked. The connector for the tablet is rather large, and covers one of the audio plugs. This problem is easy to avoid by using only one audio channel. But if you are particular about sound quality, this may
annoy you.
The AproDraw tablet is available in two different sizes, 9" x 6" and 16” x 16" (You’ll need plenty of desk space for tiiat one!). Each tablet has two application possibilities. It may be used straight, as a versatile graphics tablet on your A500, A1000, or A2000; or if you own a 2000, you can use it as a powerful CAD tablet.
The tablet driver diskette, produced by R&DL Productions, skirts the mouse signals, allowing your stylus or four-button cursor to control the screen cursor. It's very easy to install and is configured for your Amiga, so there is virtually nothing to do ... Except draw!
Wljat's the Difference Between Left & Right?
AproDraw’s most unique feature doesn't even include the tablet. It's the stylus. Quite a few graphics tablets are available for the Amiga, but none address a basic problem : the Amiga's mouse. How do you emulate the right mouse button? The tip of the stylus has always served as the left mouse button on any tablet, but the hardware developers have traditionally forgotten the right button. Well, AproDraw has come to the rescue by putting a “right” mouse button on the barrel of the stylus.
It may not be the most necessary feature of a graphics tablet, but it's nice to see a developer remember that artists use the right button, too!
If you are accustomed to De- luxePaint II, the right mouse button is an important tool for selecting and applying a second color, customizing the palette, sizing the airbrush, and using many of the valuable and time saving shortcuts programmed into the software by that most benevolent of Amiga artist benefactors, Dan Silva.
If you use the four-button puck rather than the stylus, you’ll find its precision suitable for CAD work. Why four buttons, you ask? Two function as our familiar mouse buttons. The ocher two have no function at all on the Amiga. Obviously, this cursor was designed for use with more than one computer configuration. One benefit of using the cursor is that by laying a photograph or another drawing over the tablet, you can digitize right into your CAD program!
Does It Work Well?
AproDraw is a quality graphics tablet. It is versatile and relatively bug- free. Right now it looks like the forerunner in the medium priced graphics tablet market.
The choice of two tablet sizes is a great convenience for artists who are either limited in desk space, or have an abundance of blank drawing table at their disposal.
The AproDraw is extremely accurate and sensitive (so much so that it can emulate your signature almost flawlessly). Tire only foreseeable problem concerns software. R&DL recommends using the newest versions of most graphics programs. So, if you own DeluxePaint II, you should know that the tablet works best with versions
2. 1 or later.
I tested the tablet with Dpaint II
2. 1 and had no problems whatsoever.
R&DL notified me of a bug in a previous version of the tablet driver software. If you press the F10 key while the cursor is positioned over the toolbox on the right side, the program freezes and must be rebooted. The source of this bug was never made clear, but it seemed to be a combination of things concerning their software, the tablet, and Dpaint (probably a version older than 2.1). At any rate, R&DL claims everything is now bug free.
I tried other programs with AproDraw.
Photon Paint, Express Paint, and Digi Paint all worked well and seemed to be compatible with the tablet and software.
Take a Tablet, and Call Me in the Morning I can rant and rave for ten pages about a graphics tablet and you still may not be impressed with one after you try it. There are three things to consider when you evaluate a tablet.
First, choose a tablet that addresses your artistic needs. You may prefer a tablet with freehand sensitivity and accuracy. You may need a tablet featuring many function “keys": or you may be looking for something that w-orks well with a CAD package.
Second, choose a tablet that is most compatible with the software you are using. It’s not worth buying a tablet that is going to give you some kind of guru every time you use it or one that forces you to go out and spend $ 500 on new software just to use it.
Third, and most importantly, choose a tablet that fits your price range.
You can find a tablet that does everything, but you're going to pay for it. If you choose a tablet that covers your basic needs, functions well with your software, and makes your wallet smile, you’ve found a tablet that is worth its weight in silicon.

Hints and tips to move you closer to gaming greatness!
By Jeffery Scott Hall Thanks to great reader support.
I'm back with another article on the hottest, coolest game hints and tips!
Game Pizzazz is divided into two sections: Questions and Answers and Reader’s Gaming Secrets. Also in this month's article, I have included a special section, Arkanoid Mania. So, dust off your games, get out that joystick, and blast'em!
Questions & Answers Q- I am having trouble with the gameF A-18 Interceptor. It seems that I can ’ get game to say I’ve qualified. After landing on the deck of the carrier at least six times, I still can’t obtain qualification for missions. I come to a complete stop on the deck, and I just sit there. Nothing happens! What am I doing wrong?
Stuart & Donna Wilensky Wurtsboro, NY
A. A number of things may be going wrong. Instead of guessing, I
will give you exact instructions on how to qualify for
missions. After taking off from the flight deck, you encounter
three enemy fighters directly north. -All three fighters must
be destroyed before you return. Once this is accomplished, you
must land on the ship properly.
Fly past the ship at about 40% thrust and make a U-turn, so you land from the south instead of from the north.
The ship is always located at 345 degrees and 145 feet above sea level. As you begin to land, lower the arrestor hook and continue the descent slowly. Just before you land, cut your thrust to 10%.
Once on the deck, you see the cables that catch the arrestor hook. Here your plane stops and immediate qualification is given to the pilot.
Q. When is the proper time to drop the rescue pod in Interceptor
Anonymous San Diego area
A. If you are playing the Search and Rescue mission, drop the
rescue pod just in front of tire floating pilot. Just lower
your altitude and cut your thrust until you are skimming the
water at a very low speed, Header's Gaining Secrets Faery Tale
1. An important tip: At the beginning of the game, spend some
time in the graveyard south of town. If you are patient, this
is also a good spot to get rid of a bone.
2. There are a few places that can be entered, but without
sufficient keys, you can be trapped inside forever.
3- As evening approaches, and you are caught out in the open, have one final battle and don't move until dawn. You will be safe where you are standing.
Ultima III
1. In combat with evil monsters, the best way to protect a
valuable weapon is to use it.
2. Don’t let fear of whirlpools keep you from roaming the high
3. Unless you can stop time, don’t wreak havoc in the castle of
lord British.
He has a mean temper.
4. Logical positioning of characters is the best defense
against invisible monsters.
5. When you reach the machine, recall the words of the Time Lord.
Jim and Maria Marusek Bloomfield, IN Arkanoid Mania Here are several useful game tips that apply to all ".Arkanoid Imposters."
There are also some hints and tips below that are game-specific and are labeled accordingly.
In die higher levels of the “Arkanoid Imposters," certain space walls are indestructible. When this type of wall surrounds all other walls, it is almost impossible to break through. However, this wall does have an Achilles heel. You should notice one brick missing from one of die four sides of that indestructible wall, file trick: get the energy ball through the “hole” in the wall. It’s a tight fit, but it goes through if done right, When too much speed builds up on the energy ball, collect a “slow” power capsule. This takes some of the heat off and returns things to normal.
When playing higher levels, work on the brick walls tactically. Punch a hole through the wall and let the energy ball do all the work, while you collect power capsules and rack up points. For example, knock out the first three or so bricks on the right side of a wall. Now, get the energy ball through that hole you've created. The energy ball has a field day bouncing around inside the Gase Pause Husie Sound lutflOH § Ip J Zap your game letters to: Jeffery S. Hall c o Amazing Computing
P. O. Box 869 Fall River, MA 02722-0869 walls, and all you have
to do is sit back and collect those points and power capsules.
But watch out for the return of that energy ball- when the
ball escapes the trap, the return is a doozy!
Arkanoid Only!
Want to become invincible, score over one million points, and collect power capsules at will? When you are asked which level you would like to play (or during game play), type DSIMAGfC with no spaces. This opens a “back door” to the game and allows you to command the power capsules to appear at will. Just type “p” for an extra paddle, “b" to break into the next level, etc. If you are at the requester that asks for the start level, you can scroll through levels 1 to 33- To scroll through levels 34 to 66, re-type the password and press F3- Now, you can get even for all those times that you
scored a mere 30,000 and got kicked from one end of the galaxy to the other!

STE YI02; LA MIRADA, CA. 90638 PHONE: (714) 994-4443 Star glider II AMAZING REVIEWS by Jeffery Scott Hall Starglider II, from Rainbird Software, puts you in the cockpit of a futuristic fighter jet. Before the game starts, you must enter a password from the manual. Once the proper word is entered, the title screen is displayed and a Stereo sound track plays.
The Pilot’s Mission It is your job to protect the planet of Novenia from invading Ergon forces. Not only is this planet at stake, but many others just like it are in danger. You must search out and destroy a vast space station that is being constructed. And that is not going to be an easy task. So strap yourself into the pilot's seat, energize those phasers, and prepare for some non-slop combat in outer space.
Examining the Starglider You are seated inside the Icarus, otherwise known as the Starglider, looking at the view screen, just below the view screen is a row of instruments and indicators in full 3IY These change and fluctuate with your ship for a visual confirmation of current status. In the center of the view screen is the heads-up display, used for targeting weapons and locking in objects for either identification or tractor beaming.
The Icarus has heavy offensive weaponry, including the plasma lasers, time- warp cuboids, fire and flee missiles, bouncing bombs, and neutron bombs. It’s defenses include a super strong energy shield surrounding all sides of the ship, and an audio analysis of any sounds occurring around you. To keep you up to dale on the status of the planet and your ship, at any lime you can request a status report, which will be displayed at the bottom of the control panel. Now, it is time to see how the Icarus holds up in battle.
Going into Battle You have just received word from the Novenian Council that the Ergon army has planned a full-scale invasion. After putting on your space suit, you board and launch the Icarus. Sitting in your ship, you start to wonder what freedom for your planet would be like; you are the only hope for this accomplishment.
Almost caught up in your dream, you notice the radar showing a massive fleet of Ergon forces closing in. Moving closer, you call up the target identification computer for more details about die enemy fleet. You quickly learn that most of the enemy forces are fighter jets, so you kick in the stardrive for a quick fly and take out as many targets possible. You cycle through your weapons trying to decide which one is best for this fleet. Aw, the plasma lasers ought to do the job.
As the two targets get closer, you grip the control stick tenaciously. Now, when you finally have them within range, you lock-on with the lasers to bring them both crashing to the surface.
Suddenly, you hear a sharp whine coming from somewhere nearby. You turn on the audio analysis and discover that the sounds are coming from a homing missile launched from a Ergon ground walker. Unfortunately, it is too late to take any evasive maneuvers. The missile hits your left wing, dropping you from stardrive to normal speed.
Finding the ground walker before it has another chance to fire is your only chance for survival. As you lower your altitude, you select a fire and flee missile.
This is your only option since damage has already been done to your ship. You finally locate the ground walker just ahead, and quickly increase your speed to maximum thmst and fire the missile.
As you glance back, a bright light encircles the area where the ground walker once stood. "Whew, that was a close call! You must now find a repair center. You know your mission has just begun, and the lives of billions are resting in your hands!
Summary Starglider [I combines some nice extra features that allow you to view the Icarus from any angle, whether you are in flight or on the ground. Two other important features are the abilities to pause and save the game to disk. Before now, I found it difficult to get engrossed in a flight simulator-type game. However, Starglider II combines great arcade action, strategy, graphics, sound effects, and music to keep you coming back for yet another daring flight into deep outer space!
Hints and Tips Whenever you encounter an enemy fleet, kick in the stardrive and activate the plasma lasers. As you fly past them, take out as many space ships as possible. After doing so, deactivate the stardrive and lower your altitude to minimum level, so you are skimming the planet's surface. Now, as you fly past them again, take out as many ground forces as possible. Repeat this process until you have taken out most of the Ergon fleet. In some cases, this strategy may not work; before you attempt it, use either the audio analysis or target identification. If more than ten targets are on
radar, do not engage the stardrive.
Use your own tactics for survival.
When using the tractor beam, make sure the object mass is not too great for the Icarus to handle. If it is, a message tells you so, and the tractor beam must be immediately disengaged.
Trying to use the tractor beam on an object too large destroys the Icarus and ends your mission!
Make sure you check the status report frequently, so you are aware of the planet’s condition and any other information vital to your mission.

AMAZING PROGRAMMING STRUCTURES by Paul Castonguay If you have taken more than a passing glance at C program listings for the Amiga, you have seen lines like these: struct Window ’wind; struct NewWindow wnd; wind = (struct Window *)OpenWindow(&wnd); rp = wind- RPort; Are you having trouble understanding what these lines mean? Have you been scared away from programming your Amiga in C because of them?
These lines deal with a concept called structures, and understanding them is essential if you want to do even simple things like opening windows and drawing graphics. In this article, I will explain structures to users already familiar with BASIC. To enhance the discussion, I will mention variables and arrays, but you should already understand them from your work in BASIC.
Most programming textbooks start this discussion by stating that structures are a data type.
Data is information. Programs either use or generate data. A program that calculates your bank balance uses numbers as data. Your word processor uses letters and words as data. Because of the way computers work, data is stored differently depending upon whether it is numeric or alphabetic.
.Also, if it is numeric, it depends upon whether the numbers are integers or decimals. The C language takes care of these details by providing you with variables of different data types. To store a letter, use a character type variable. Here "junk” is declared as a character variable and the letter Z is stored in it.
Char junk; junk= 7'; Here the number 23 is stored in the integer variable called "bunk.” int bunk; bunk = 23; .And here my annual salary is stored in the Roaring point variable "stunk.” float stunk; stunk = 18.42; C has short integer variables which let the computer run faster, and long integer variables to store larger numbers. Unsigned integer variables store only positive numbers. There are also single and double precision floating point variables: float answer; double e_base; e_base = 2.7182818284590453; answer = 2*3.1416*2.2E-06; in C A BASIC user’s guide to programming C structures.
So... a data type is that attribute of a variable which determines the kind of data it can store. The data types mentioned so far are called fundamental, or elementary, data types.
They represent the smallest units of each kind of data that can be stored. Each type is unique, and variables of each type will store exactly one piece of data.
BASIC also has data types: STUFF? Is used to store words JUNK is used to store floating point numbers You must have a good understanding of C’s fundamental data types. I recommend C Primer Plus, by M. Waitz. Now I must press on or I will never get to structures.
Derived Data Types These are data types which are made up of other data types. The simplest example is the array. An array can store a whole bunch of data of similar data types under one common name. Each unit (called an element) is individually identified by a special number called a subscript. Let me declare an array which can store ten integer values.
Int scored 0); In it I will store my ten best bowling scores, one in each element of the array “score.” ScorefO) = 86; scored) = 92; score[9) = 103; They form a group as they all have the common name "score.” I can use that to my advantage if I print them, for (i=0; ic 10; i++) printf(‘My score in game %d was %d n i+1, score(i)); } In C, the first element of the array is score[0], making the tenth element score[9J. Arrays can be any size or type you want, but most importantly, each element of a particular array must be of the same data type. In my example each element must be an integer. I
cannot use the array “score" to store the name of my granddaughter’s pet lizard. For that job I need a character type array: char !izard(25); strcpyflizard, '“Marmaduque"); Here I can store any lizard’s name of 24 letters or less. C requires one extra element in the array to mark the end of the character string. Notice the use of C’s string copy function, called strcpyO, to put a string into an array. You will have to study up on character strings in C if this appears difficult.
If I want to store many lizard names, I need a two dimensional array like this: char lizard(5)(25); Here I can store five lizard names.
Strcpy(lizard[0), 'blinkin'); strcpy(lizard[l), ‘Stinkin'); sfrcpy(lizard[2), ‘Frog'); etc... And you can print them out: for(i=0; i 5; i++) printfClizard %d is called %s', i+1, lizard(i)); In listing 1 you'll find an example that you can try out.
Compare C’s arrays to BASIC’s DIM AS(25) DIM X(100) AS(3) = "My aunt Rose’ X(42) = 3.1416 If you don’t understand arrays in C or BASIC, you’re not ready for structures yet.
Structures Structures are like arrays in that they are a derived data type, and that they allow many pieces of data to be stored under a common name. They are, however, more powerful than arrays in that they allow storing different data types. A single structure can store integers, characters, and floating point numbers, all under a single variable name. A structure can even store other derived data types like arrays and other structures.
The Amiga’s operating system often uses structures.
Each piece of data stored in a structure is called a member of that structure, and each member is referred to by a member name. This differs from arrays, which use subscript Nothing but the best.
Now even better with twice the showroom space!

Service Center numbers to identify each element. Let me
define a structure which can store information about any of
my girlfriends.
Struct girlfriend !
Charfirst_name(25): char iasLname(50): int age: char street_address(50); chartown(25); int zip, float annualjncome; long integer boyfriends, ); The above code is called a template for the girlfriend structure. Tire girlfriend structure is now a new data type which can store someone's first and last name, age, address, annual income, and number of boyfriends. The girlfriend structure is unique in that it will store only the kind of data that I designed it to store. If you were looking for a place to store your monthly bank statement, you couldn't use a girlfriend structure. Only one member of a
girlfriend structure can store a floating point number. That’s not enough for your bank statement.
One point of confusion in the above code may be the exact meaning of the word girlfriend. Girlfriend is not a variable name, it is a data type. I will not store data about any of my girlfriends in a variable called girlfriend, instead, i will declare a variable to be of type girlfriend and then store data in that variable. Let me do this for three variables: struct girlfriend best; struct girlfriend worst; struct girlfriend average; Here I have declared three variables: best, worst, and average. They are each a separate variable, and each one can store all the information I want about a
particular girlfriend.
Each one is a girlfriend structure and has eight members with member names as defined in the template above. For example, best, average, and worst each have a member called first_name.
We say that “best is a girlfriend structure." Similarly, “worst" and “average” are girlfriend structures. A girlfriend structure is a data type just like char, int, float, or any of the others. To use it, 1 have to declare a variable to be of that type, as I did above.
Referring back to my template for the girlfriend structure, notice that I, not the computer, decided exactly what kind of data a girlfriend structure would hold. To do that, I was required to make up names for each member of my stmcture and declare the appropriate data type of each. The member annualjncome, for example, had to be a float type member because I wanted it to store a number with a decimal point, hr each case I chose a descriptive member name, just as I would for any simple variable.
OK... so how do 1 go about actually storing data into a structure? I must refer to both the structure name (best, worst, or average) and the member name. There is a special notation which allows me to do that. First I write the name of the structure, the member operator, a period, and finally, the name of the member I am interested in. Let me store some data about my favorite girlfriend in the structure I declared as “best."
Strcpy(best.first_name, “Gwendolyn*): strcpy(best.last_name, 'Bonk'); best.annuaijncome = 145932.75; best.age =31; best.boyfriends = 185; The period is formally called the “structure member operator." I like to call this notation the “dot notation.” I can store the data in any order I want. Each piece of data is individually assigned to its respective member and each assignment has no effect on other members of the stmcture. I can assign data to the equivalent member of different structures like this: strcpyf worst. Last_nome, "Kazaokenberger”); strcpy(average.last_name, "Zonk'); Great! Now
how do I access the data in these structures once I have put it there? I use the same structure member operator, the dot notation. Here a print statement shows what is stored in two members of the girlfriend structure called “best”: printfCMy favorite girl is %s n', best.firsf.name); printfCShe is %d years o!d n', best.age); Individual members of a structure can be used exactly like any simple elementary variable of the same data type. Here is a line from a program I wrote to update my girlfriends' salaries: worst.annual_solary = worst.annual_salary - .06; best.annuaLsalary =
besf.annual_salary + 17532.23; Here; floating point calculations are done to members of different structures just as if they were ordinary floating point variables.
One Last Time A structure can store a bunch of data containing different data types under a common variable name, with each piece identified by its own special member name. The dot notation can refer to any member of the staicture. BASIC doesn't offer staictures as a data type.
One of the most powerful uses for structures is passing large amounts of data between functions. The Amiga people realized this when they designed the OpenWindowO I unction in Intuition. They knew programmers are fussy people who want almost every kind of window imaginable, different sized windows, with different locations on the screen, different gadgets, different colors, and so on.
How does die OpenWindowO function deal with all these requirements? Do we have to pass a multitude of arguments to the OpenWindowO function? No. Instead, we store all our window characteristics in a structure called NewWindow.
The template for this structure has been conveniently placed in the header file Intuition Intuition.h . Thank you, Amiga!
It's a smart idea to get a hard copy of this file and refer to it as you program your Amiga. In version 4.0 of Lattice C, this file is on disk -3- The file is long. 1 printed it using my word processor so I could add page numbers. The NewWindow template starts near the end of the file on page 17.
Notice the member names. LeftEdge, TopEdge, Width, and Height are so descriptive you could probably use them without any special instruction. But others, like IDCMPFlags and
• FirstGadget, look rather intimidating. How do you use them?
Don’t worry about that just yet. At this point it is only important to know that a structure called NewWindow has been defined for you, that it has descriptive member names, and that you will be storing some data in those members using the dot member operator notation.
First we declare a variable to be of type NewWindow.
Remember that NewWindow is not a variable name; it is a data type. To use it, we have to declare a variable of that type. Look in program listing “2 at the end of this article. At the top of the mainO function is the line: struct NewWindow my_window_request; I have defined “my_window_request” as a NewWindow structure. Since this structure stores all the details about the kind of window I want to open, I gave it an appropriately descriptive name. You can call it anything you like. After all, it's your variable.
Now we assign each member the properties we want our window to have. Look further down in the listing. You'll see things like: my„window_request.LeftEdge=50: my_window_request.TopEdge=25; This is the now familiar dot member notation we saw- earlier. You can probably guess that these lines have something to do with where on the screen the window will appear. Other assignment statements like: jr THE HonEST AMIGA STORE IN THE COUNTRY.

Be patient.
Before w-e can learn the exact meaning of every member of each structure in the Amiga operating system, we must make absolutely sure that we understand what structures are and how to use them. For now, just accept that I have stored some data into the various members of the NewWindow structure which I called "my_window_request." Don't worry if you don’t yet understand what the data means. Trust me, all the data is legitimate.
Notice, however, that some members, like my_window_request. Width, store numeric data, while others, like my_window_request.Title, store alphabetic data. The power behind structures is the ability to store different data types under one name, my„window_request.
Sometimes you will see a NewWindow structure in a program listing, initialized using a shorter notation which does not explicitly mention the member names. Do not use that notation. It is used by insecure software writers who believe their only chance for success in life is to write code so badly that no one, including themselves, will ever understand it. Use the member names for the same reason you use descriptive names for any variable; so your source code is more understandable for yourself and others.
OK, here’s the part you’ve been waiting for. How do I pass all that data to the OpenWindowO function? Surprise! I do it with only one argument. 1 pass OpenWindowO die address of die NewWindow structure, which I called “my_window_request.” You see, the OpenWindowO function is very smart and already knows about NewWindow structures. All it needs to read and use all the data stored in any NewWindow structure is the structure’s memory location. Effectively, all that data gets passed to the OpenWlndowO function in one swoop.
Here is the required notation: OpenWindow(&my_window_request) The & is the address operator in C. Prefixing any variable with the & operator passes the address of that variable, not the actual data it contains. Here, the address of the structure "my_window_request" was just passed to the function OpenWindowO. Knowing that address, the OpenWindowO function is able to read and use all the data contained in each of its members. The system responds by displaying a window with all the characteristics I asked for.
Two points worth repeating Rather than pass all that data to the OpenWindowO function one member at a time, I simply told the OpenWindowO function where to find a structure which contained all the data. And I couldn't have done it without a structure, because only structures can store different data types under one name.
Pointer notation Just when you thought you understood everything about structures, I mined everything by introducing a new concept. Is this really necessary?
C uses pointers a lot. It’s easier to pass data by referring to its address than by referring to the data itself. This was obvious when we called the OpenWindowO function and passed to it the address of our NewWindow structure "my_window_request.” We did that by using the & operator. So why do we need pointers? The & operator works only with structures which have a variable name, and many times we need to refer to the address of a structure which has no variable name to refer to. This happens when the operating system passes information back to us in the form of an address to a structure.
When we executed the OpenWindow(&my_window_request) function, it went off and created a window according to the specifications we stored in the NewWindow structure "my_window_request." But suppose that now, after the window has been created, you wish to refer to some property of that window. Maybe you are writing a scaling routine and want to know’ the exact size of the window.
You could refer to the original Width and Height members of the NewWindow structure used to call the OpenWindowO function in the first place.
But that may not work! Suppose the user resized your window after it was opened. He she could certainly do that if you provided a re-sizing gadget. My example program at the end of this article does not allow that, but it could easily be changed. The Height and Width members of my_window_request represent the window s size when opened, not necessarily its size at some later time. To make my point even clearer, suppose you needed to refer to some other property of the window that is not even described by a member of the NewWindow structure. You will have to do that if you want to draw’ simple
graphics in your window, Iloti’ are these things done on the Amiga?
In addition to making a w’indow on the screen, the OpenWindowO function, creates a Window type structure. Look in intuition intuition.h , on page 14, and you will see that a Window structure has many more members titan the NewWindow’ structure you used earlier. You'll see members describing every’ possible attribute a window could have its size, position on the screen, default colors, and so on. In addition to knowing all the member names for the NewWindow structure mentioned earlier, the OpenWindowO function is smart enough to know them all for the Window’ structure as well.
The OpenWindowO function also stores, in each one, information about the window it has just opened, Most importantly, the data stored in the Window* structure is constantly updated by the operating system whenever the characteristics of your window are changed, either by the user or by your program. It is from this structure that you get the latest information on window size, window location, and many other features, Where is this Window structure?
When you use the OpenWindowO function, it returns a number which is the address of the Window’ structure it created for you. It passes you the same kind of information you passed to it when you used the address operator.
But now, how do you use it? Up until now you have referred to data stored in a structure only by specifying the name of the structure, the structure member operator, and the member name you wanted. Unfortunately, the OpenWindowO function doesn’t pass the name of the Window structure it created for you. (Remember, the w’ord Window is not a variable name, it is a data type!) In fact, the Window’ structure the OpenWindowO function created doesn't even have a name! It has only an address. Hmm... You can't use the dot member operator notation, can you?
Sounds like a job for a pointer!
A pointer to a structure does two things. First, ii stores the structure’s address, Second, and more important to you now’, it knows all the member names of the structure it points to and allows you to refer to them by using a special notation.
Let’s talk about first things first. Look in my listing at the end of this article. At the top you will see the declaration: struct Window ‘my_window_received; I have declared a pointer to a Window structure. The * symbol is the pointer operator. This variable, my_window_received, will store the address of the Window structure w’hich will be created when the OpenWindowO function is called. Here is how’ this is done; my_window_received = OpenWindow(&my_window„request); This line not only creates your window, and a Window structure containing all the properties of the window just opened; it also
stores the address of the Window structure in the pointer called “my_window_received.” This is really no different than any assignment statement of a value returned from any function. Here are some more familiar examples: x = sqrt(25.0); char = getcharO; my_wlndow_received = OpenWindow(&my_window.jequesi); In each case, the value each function returns is assigned to the variable. The value returned by the OpenWindowO function, which happens to be the address of the Window structure, is assigned to the pointer variable '‘my_window_received.’' Now, second things second! Each pointer variable
knows all about the member names of the structure it was declared to point to. Pointers receive that knowledge when you declare them. You see, “my_window_received” was declared to point to not just any structure, but to a Window structure.
In addition to this, pointers use a special notation which allows you to refer to any member of a structure by name. 1 like to call this notation “little arrows." Let’s use it to refer to something simple, like the size of a window, Look at your printout of Intuition lntuition.h and notice the member names Width and Height in the Window template. Suppose I wanted to know what is stored in those members at any time. Here is the required notation: my_window_received- Width my_wlndow_received- Height The arrow is fonned by typing a hyphen, followed immediately by the “greater than" symbol.
When you use this notation, you are telling your Amiga to “look in the structure pointed to by 'my_window_received' and tell me what is stored in the member called ‘Width’." This notation can be used in assignment statements, just like the other dot notation you learned earlier.
Window = my_window_received- Width; wind_h = my_window_received- Height; Also, these members can be used just like any variable of similar type. Suppose you wanted to calculate the midpoint of your window for scaling purposes. Note that intuition intuition.h declares both Width and Height to be of type SHORT. You might do something like this: SHORf mid_x, mid_y; mid_x = my_window_received- WIdth 2; mid_y = my_window_received- Height 2, Now you may use the values stored in mid_x and mid_y to plot a point at the exact center of your window.
Try not to feel overwhelmed by the long list of members in the NewWindow and Window structures. 1 know it all looks very complicated at first, but you don’t need to understand the purpose of every member. Many members represent features of the operating system that you may never use; give these a simple default value like NULL.
Still, I know you are anxious to find out about them, so very soon 1 will talk about the meaning of one, the RastPort member of the Window structure. But right now it is important that you understand what a structure is and how to refer to data stored in it. Only when you feel comfortable with that can you begin to learn the exact meaning of any member of the many structures defined in the Amiga operating system.

Inc Recapitulation Two notations are used to refer to the members of structures. The dot notation uses a structure's name, the dot operator, and the member name. The pointer notation uses the name of a pointer to the structure, a little arrow, and the member name. Use the dot notation when you know the name of the structure. These are usually structures that you declare yourself in your program, like the NewWindow
structure you called “my_window_request.” Use the pointer notation when you know the name of the structure's pointer. These are usually structures the operating system has declared for you, like the Window structure, whose address is stored in the pointer '‘my_window_received," The Rastport The first structure member you should learn on the Amiga is the RastPort pointer. The RastPort pointer is a member of every Window structure. It points to another structure which, incidentally, is also created when tire system opens a new window for you. (A fine machine, that Amiga!)
Remember how I stated much earlier that structures could store any data type, even other structures? Here you have a Window structure which contains, as one of its members, a pointer to a structure called RastPort. Don’t be concerned about this added complexity. The only thing you need to know about the RasrPort structure is how to get its address as required by the graphic functions you want to use. You will do this with tire pointer notation, the "little arrows." Suppose your program opens a window whose pointer is called “my_window_received." You probably used the OpenWindowO function like
this; struct Window *iTiy_window_recetved; struct NewWindov my_window_request; Then, after loading my_windo v_request with data.
My_window_received = OpenWindow(&my_wincow_request); The pointer “my_window_received” points to the Window structure the system created for you. To use the MoveO and DrawO graphic functions in that window, specify the RastPort of the window in which you want to draw. You see the Amiga can easily draw graphics in many different windows which may be open on the screen at the same time, It makes sense, then, that you, the programmer, must tell the system which window you want the graphics to be sent to by passing a RastPort address to each graphics function used.
By specifying a RastPort address, you are telling the operating system which window you want tire graphics to go to. The RastPort address for any window is stored for you by the operating system in the RastPort pointer, which is a member of every Window structure and has the name Rport. Here’s how you send graphics to the window pointed to by ';my_window_received": Move(my_windowjeceived- RPort, 25, 10); Draw(my„window_received- RPort, 300, 90); This will draw a line in your window. Many programmers find it easier to use a shorter variable name instead of "my_window_received- RPort”; struct
RostPort ‘rp: * declare a pointer * rp = draw-window- RPort; ” store RastPort address 7 Then you can use the more convenient notation; Movefrp, 25, 10); Drawfrp, 300, 90); Let's go over this because it’s important. Look again in intuition intuition,h and find the declaration of the RasrPort pointer. It's at the top of page 15 in my printout. It says: Struct RastPort 'RPort; The name of tire pointer is Rport and it points to a structure of type RastPort. Rport is the name of the pointer, RastPort is the data type that it points to. The expression: my_window_received- RPort tells your Amiga
to look in the Window structure my_window_received and see what is stored in Rport. That member lias been defined by Lhe template in cintuition intuition.h to be a pointer to a RastPort structure, and thanks to the designers of the Amiga, the number stored there is the address of the RastPort structure for your window, It is used as an argument for any graphics functions you want to use. It tells those functions in which window to draw their graphics.
Incidentally, every staicture must have a template, and Lhe RastPoit is no exception. You can find the RastPort template in the header file graphics rastport.h . It is automatically added to your program when you include cintuition intuition.h . As you develop your skills on the Amiga, you will want to look at the RastPort template.
One last point. You may have noticed that I have been careful to use upper case letters when required in the names of the NewWindow, Window, and RastPort structures. Remember that the C language is case sensitive, and these structures will not work if you do not write them correctly. Rastport is incorrect; it's RastPort.
Example Program Listing *2 is a short program which opens a window on the Workbench screen and draws a triangle in it. Notice how the data for the window is first stored into a NewWindow structure by using the dot notation, member by member. Notice the MoveO and DrawO function calls. They use a variable called rp to refer to the RastPort pointer. This tells the system which window' you want the triangle drawn in. If you had opened two windows, and you are certainly free to do so, you could draw first in one window, and then in the other, by specifying the RastPort pointer for each window in
Finally, look at the call to ilie OpenWindowO function.
What’s that (struct Window ’) doing in the line which calls the OpenWindowO function?
The ( struct Window *) is called a cast statement, and is there only because your compiler prefers to see it there. You see, the value the OpenWindowO function returns is an address just a long integer. In your assignment statement, you store that number in a pointer to a Window structure. Your compiler sees this and wronders if you know what you are doing. It looks on the left side of the equation and sees a pointer to a Window structure, it looks on the right side of the equation and sees a long integer number. It recognizes that these data types don’t match and sends a warning. Version 4.0
of Lattice reports, “Pointers do not point to the same object.’’ There is no problem, however, because you do know what you are doing and it is perfectly legal to store the address returned by the OpenWindowO function in the pointer “my_window„received.” Actually, it’s nice that your compiler recognizes the above data type mismatch because many times when you write programs, you will indeed not know what you are doing, and such a warning will alert you to a possible bug which would otherwise be difficult to find.
The cast statement (struct Window *) tells the compiler to treat the number returned by the OpenWindowO function, not as a simple long integer number, but as rtn address of a Window structure. Tire compiler says okay, assumes now that you know what you are doing, and continues without issuing any warning.
The cast statement (struct Window *) is not really necessary. You may write your program without it if you choose. I must admit, the line is easier to understand without the cast statement. If you leave it out, your compiler will issue a warning for that line of the program. Simply ignore the warning. If you put the cast statement in, you will not get the warning message.

P. O. Box 304 Coventry. Rl 02816 Amiga is a registered trademark
of Commodore-Amiga, Inc. data from a Window structure. What I
have not done was explain, one by one, the exact meaning of
each member of these structures. Throughout the article, I
have asked you to not worry about this, emphasizing the more
important goal of learning about structures. That done, now
you probably want to know more about the meaning of each
member of these and many of the other structures designed into
the Amiga's operating system. However, I am not going to
explain those to you.
Feel cheated? Don’t. If you didn’t understand structures when you started reading this article, and if you were able to follow everything I have presented, you have made a giant step in your understanding of the Amiga. You have conquered what I believe is the most difficult obstacle to programming the Amiga in C. You have learned what structures are. So, now what do you do? I know that opening simple windows will not hold your interest very long. Armed with an understanding of structures, member operator notation, and pointer notation, open your AMIGA Intuition Reference Manual by Addison-
Wesley and see if you now understand what it is talking about.
Take the NewWindow structure, for instance. An explanation of each member starts on page 65. The first four are pretty easy. Specifying different values there will open windows of different sizes. Specifying illegal values will crash your machine! Fun, huh? DetailPen and BlockPen can be a pen number or a minus one. That’s easy enough. But look at all that stuff for Flags! How are you going to understand all that? You won’t, at least not right away.
What you must learn, however, is that ail those names, WINDOWSIZING, WINDQWCLOSE, SIMPLE_REFRESH, and so on, are actually definitions in the header file cintuition intuition.h . Each capitalized argument is a macro which has been conveniently defined for you and which you are free to use by specifying it by name. (Thank you again, Amiga! )lf you want to use more than one, and you usually will, separate each with the OR symbol, which in C is the character “ I ”. (The I key is just left of the backspace key.) Use my program as a model to do the same in your own programs.
If you get stuck trying to understand any of these members, or find the explanation in the Intuition manual incomplete, try another reference. I suggest Inside the Amiga by John Berry, Inside Amiga Graphics by Sheldon Leeman, Programmer’s Guide to the Amiga, by Robert Peck, and Amiga Programmer's Handbook by Eugene iMortimore.

And even more important in the Amiga's multitasking environment, HardFrnme 2000 has extremely efficient DMA circuitry to get on and off the bus in almost no time at all: 280ns to get on; 200ns to get off. HardFrame 2000 autoboots under AmigaDOS™ 1.3 and is fully compatible with the new Fast File System. The core of any DMA SCSI interface is its SCSI protocol chip and DMA chip. MicroBotics has chosen the new, high
performance Adaptec AIC-6250 SCSI chip, capable of up to 5 megabytes per second raw transfer speed, and the Signetics 68430 DMA chip running at 12.5 megahertz. Then we added additional FIFO buffering and enabled 16-bit wide data transfers for maximum throughput. The sophisticated design of HardFrame 2000 provides for automatic SCSI arbitration, selection and reselection, The hardware supports either synchronous or asynchronous data transfer. HardFrame 2000 can function as either the SCSI bus initiator or the target and can reside in a multiple master environment. Physically, HardFrame
2000 is optimally flexible: the compact, half-size card comes attached to a full length, plated aluminum frame. The frame has mounting holes positioned to accept standard, 3.5" SCSI hard disk units such as those manufactured by MiniScribe, Seagate, Rodime, and others (hard disk mechanisms must be supplied by the user or his dealer as a separate purchase item). Alternatively, you can cable-connect to a SCSI drive mounted in your Amiga's disk bay or in an external chassis. As many as seven hard disks may be connected to a single HardFrame. There is no size limit on each disk. HardFrame 2000
includes a 50-pin SCSI cable and header connectors for either 50-pin or 25-pin cable connection.
Also included is a current tap to power frame-mounted drives directly from the slot itself. HardFrame 2000 comes complete with driver, installation, and diagnostic software. Available September 1988.
Suggested list price, S329 (hard disk not included).
HardFrame 2000 8-UP! The Eight Megabyte The Super-speed, DMA, SCSI Hard Memory Card with Amiga-specific Disk Interface with 1.3 Autobootmg DRAM Controller Logic All the memory space you and your Amiga 2000 need -in a modern, highly integrated FastRAM expansion board. In 8-UP!, MicroBotics went all the way to provide you with a truly Amiga-specific memory design to meet tire special demands of the Amiga's high speed multitasking environment: The heart of any memory expansion is its DRAM controller circuitry. Rather than compromising with off-the-shelf parts, MicroBotics developed its own,
custom controller design and built it into high-speed. Programmable Macro Logic chips (Signetics PLHS501), These new, super chips (each 8-UP! Uses two Pml.'s) permit MicroBotics to employ sparse refresh technology to assure that your 8-UP! Is a truly zero wait-state minimal-refresh- collision memory design. If you're putting eight megabytes in only one slot, that means that you probably have plans for your other A2Q00 slots. 8-UP! Gives you new freedom to do that planning since, unlike other ram peripherals, it is an extremely low- power memory card- a single, fully-loaded, 8-megabyte
Draws an astoundingly efficient 800 milliamps! That's less than two-fifths of the power "budget" for a single slot! Low power draw also means that the card is cool-running for reliability and long life (not to mention a cooler Amiga!). 8-UP! Offers you maximum flexibility in memory configuration: it is organized into two separate PIC's (Amiga-speak for autoconfiguring peripherals). Each 8-UP! PIC consists of four SIMM module sockets; these sockets accept either 256k-byte or 1 megabyte SIMM's (Single Inline Memory Modules). You can also purchase optional PopSIMM boards from MicroBotics; fill
them with conventional RAM ; then use PopSIMM's to fill your 8-UP! The card can run with as little as 512k of memory or as much as eight megs -with many intermediate configurations possible (particularly the six megabyte configuration, most desirable for use with a BridgeCard™). 8-UP!
Is speedy, efficient, custom memory technology for your Amiga 2000 -and it S available now! 8-UP! Suggested list price is $ 199 (0k installed) Optional PopSIMM's are $ 49.95 per pair.
The memory location The HardFrame 2000 photo shows the product with a MiniScribe 20 megabyte hard disk installed. Hard disks are not included in the purchase price of HardFrame. Note that if placed in the first slot, HardFrame uses only one slot.
The 8-UP I photo shows the card half populated with conventional SIMM modules and half with MicroBotics PopSIMM's. PopSIMM's (without DRAM installed) are available as separate purchase items.

Publishing with Professional Page by Barney Schwartz This month
I will create a document using Gold Disk’s Professional Page.
Professional Page version 1.1 hit die streets in May of this year. As usual, Gold Disk has released two improvements to version 1.1 since May. First they offered a new metric file utility which greatly expands the postscript library in 1.1, allowing a much larger varity of fonts for PostScript users. Now they have introduced a new toolkit for dot-matrix users. This toolkit will build a metric file from any Amiga screen font file, giving you satisfactory output from Professional Page to your favorite dot-matrix printer. These new utilities and the 1.3 printer drivers which ship on version 1.1
help make Professional Page a desktop publisher for all users.
The new printer drivers increase graphics printing speed by 200 to 600 percent. They also allow multiple density printing and color correction, which lets you create good quality newsletters with your trusty nine-pin dot-matrix printer, or excellent quality flyers and articles from a laser output device.
Your readers will appreciate your efforts and you will no longer have to spend a great deal of money on printing services. You may, however, spend a lot of time waiting for your copies to roll off the printer. Even though 1.3 greatly enhances print speed, the time it takes you to get to a final product depends on your skill and knowledge of the publishing art. To this end, let us begin.
Look at figure 1. Those of you who have grown up with the Amiga will recognize it as TUT. It was done in Low-Res mode on Electronic Arts Deluxe Paint. For every piece of art which must be "pasted” into your article, two things must be considered:
1. Size of original versus allowable space.
2. Colors in original versus colors in final copy.
Those of you who are familiar with TUT realize that what you see here is not the same size or color as the original version. The screen colors don’t match the output of an Epson JX-80 printer, and the original 5"x7" size was unacceptable for this column. As with almost every graphic, this piece required some manipulation prior to incorporation in the article.
Next, you must decide on your page layout.
Will you have headlines? How many columns will you use? Will you require graphics? In which typeface and size will you set the body text? The Professional Page manual contains a wealth of information on all of til.
These subjects. I find the discussion on column width particularly interesting.
“The easiest reading body copy (text of an article) should be set in at least ten point type in columns no smaller than one alphabet wide (a to z). An optimum length is one and a half alphabets. The alphabet is used to measure because it has balanced character widths. As a general rule, a column should not be wider than two alphabets.
Figure Two: Structured graphic from AegisDraw Figure Three: Comparison of IFF Images As they appear on (Top B&W Bottom Color) the Another rule of thumb is that the line length in picas should not exceed twice the point size. If you are using ten point type, then columns should be no more than twenty picas long. A line should average nine or ten words."
Bitmapped Graphics We now return to the task at hand, dealing with graphics. The first thing to. Do with a piece of art is to print it. (I usually just install Grabbit and print to the line printer what ever is on the screen.) This immediately shows what must be done to get the colors correct.
Once you know what adjustments are necessary, enter an art program and make the necessary changes before installing the graphic in Professional Page. This is necessary because Professional Page, like most other desktop publishing packages, doesn't display color graphics. As a matier of fact, with Professional Page you don’t display your graphic until it is time to go to press.
This will save you valuable time during composition. Of course, if you choose not to display your pictures, you must remember which picture is where.
Once you adjust the colors to fit your printer, you should place your graphic- file on an “issue" disk. Your “issue" disk should contain all of the graphics and text files required for the article you plan to publish. As a matter of habit, I usually format a disk, name it the article’s name, make two separate directories ( one for graphics another for text files ) and begin planning. An “issue" disk is not required, but I have found it helps me stay organized, and saves disks swaps when I am finally ready to go to press.
Notice that I have said nothing about adjusting the size of the graphic.
You may choose to pat the graphic on the onboard or directly into your document. I prefer to put a blank box of the allocated size in the document and place the graphic on the artboard. This allows me to cut, crop, or resize the graphic to fit the allotted space. Once the graphic is cut or cropped, it will be sized to its proper dimensions. When you are satisfied the graphic is correct, transfer the finished piece to the document.
Graphic sizing can be accomplished from within Professional Page.
Instructions for scaling a graphic are rather cryptic and obtaining the desired size may seem like a chore. But things are not that complicated. With the graphic box ACTIVE open the active box requester. Within this box you will see:
1. All margins inside the box. 2. The position of the box on your
page. 3- Scaling factor in the X and Y directions (planes).
Use the scaling factor, which will be set to one initially. Adjust the factor until you have the correct size for your document. For example, suppose you start out with a graphic seven inches wide and five inches high. In your document, you want the graphic to be three and one half inches by two and one half inches. Set the X scale and the Y scale to point five. This will yield a graphic one- half the original size.
Structured Graphics What are structured graphics?
Look at figure 2. This is a structured graphic from Aegis Draw, It is not output as IFF bit-map, but as a series of vector lines. Professional Page inputs and scales these drawings much easier than IFF bitmapped graphics. (This may be because the internal drawing utility is a structured graphics form.) There is usually no need to adjust colors for proper printer output, since the only colors are prime (i.e., RED, CYAN, MAGENTA etc.). The only draw-back to using this type of graphic is that your desktop publisher will not be able to read the stroke-font for lettering and measurements within
the graphic. If this text is important, you may overlay boxes within the graphic. At any rate, you will probably appreciate the fine detail available from structured graphics.
Hold and Modify Graphics Hold and modify (HAM) graphics are to me the most impressive type of graphic in the Amiga's large inventory of svelte tools. And they are so easy to use.
You just open a box in the artboard, import IFF graphics (this time it's a digitized photo from Digi-Paint), size it to fit, crop and insert the graphic. If you feel color would be more effective for your graphic, and your graphic is black- and-white, you can shade it with one of tire many image processors available.
But that will be the subject of a future column. For now let me say that any of the following image processors would be well woith the investment:
1. Butcher, Eagle Tree Software.
2. Digi-Paint, NewTek.
3- Photon Paint, Microlllusions.
4. PlxMate, Progressive Peripherals For an example of what you
can do using digitized color graphics, see figure 3. This
should convince you of the utility' of color on a dot-matrix
printer. If there is one thing a laser cannot do, it is color.
True, lasers can sometimes do better text (but the
best typesetters do the best job). Lasers are also faster than
most dot-matrix printers (once you gel them printing). But
they don't do color and they do cost big money.
Professional Page will accept any IFF graphic,including HAM. It will take color, black-and-white, or any image processed graphic. The only requirement is that the piece be IFF. There is one thing to consider when you work with such high resolution graphics: reducing size reduces detail. The more reduction the greater the loss of detail, the more detail you lose. This is not something to worry about, just don’t expect a reduction to show every little detail.
Text & Word Processing Text makes up most of any published document. Desktop publishing provides a means of incorporating text and graphics into a final page. But the desktop publishing package is usually not designed to perform word processing. This is not to say that you cannot word process with a desktop publishing package; you certainly can. However, you may find it much more convenient to write on a familiar word processor.
After you've written y'our article, compose the pages in the desktop publishing package.
All true desktop publishers allow importation of text from many word processors. But some word processors are easier to transport than others.
Perhaps the easiest text files to incorporate into formatted pages are pure ASCII files, files consisting of ASCII text characters only. Most word processors imbed format codes within their files.
These imbedded codes facilitate proper output to printers from the particular wordprocessor. But these same imbedded codes wreak havoc on the composition artist.
It is possible to import formatted text from such popular wordprocessors as WordPerfect, Scribble!, and TextCraft, but even the best translation routines will not strip all of the format codes. This task is left largely to to desktop publisher. Tit is is why I choose straight ASCII files to be imported into desktop publishing programs. When I say straight, I mean pure text strings: no paragraphs, no indents, no soft line ends, For the “Well Adjusted” Amiga...

I use WordPerfect most of the time. This is because I’m used to it, not because it is better chan the others, There are a multitude of really good word processors for the Amiga. (Each word processor is particularly well suited for a specific task: some are full desktop publishing, some straight word processs- ing, etc.) Anyway, after I write an article, and before I import to the desktop publisher, I strip all codes. Lately, though, I’ve been using TextEd Plus to do most of my work. A text editor eliminates the requirement to strip codes, saving valuable time.
TextEd Plus from MicroSmiths or CygnusEd Professional from ASDG, used with AREXX from William Hawes are two of the greatest text processing engines I’ve come across to date, i hope to discuss the capabilities of these programs in depth in a separate article. A bit of advice: if you haven’t tried TextEd Plus or CygnusEd Professional, do so now.
They are the only totally user configurable text engines. They can be whatever you want them to be. You can customize all aspects of their operation through the .AREXX macro interface.
AREXX is another program that deserves a more attention. AREXX allows modular software to interact in a true multi-tasking environment. This allows for a module of one program to access modules inside another program, thus using available memory and time their capacity. As more modular software becomes available, and the industry expands to meet the challenge, the entire Amiga community will benifit.
Types tyles What is type? What are the differences? What are the choices of output methods? What's so special about Gold Disk's Professional Page?
According to Webster, type is a rectangular piece of metal or wood with a raised letter in reverse on its upper end, which when inked and pressed against paper or other material leaves an impression of its face. So, "typeface" is the design of a particular letter in a particular font. It is safe to say that there are hundreds of thousands of typefaces.
But there are only three basic typestyles: Serif, Sans Serif, and Ornate.
Serifed type is the typestyle most publishers will agree is the easiest to read. Therefore it is usually reserved for body copy, text which makes up the bulk of printed matter. Fine examples of serifed typefaces include Garamond, Baskerville, and Palatino. Serifed type has small "tails" or hairlines at the end of each vertical stroke in the letter. Theoretically, these serifs visually connect each letter, which provides for smoother, more comfortable reading.
Sans serif type does not have these hairlines on the vertical strokes.
Each letter has the same line weight on all strokes. This gives each Letter a blocky appearance which is less suitable for body copy but is ideal for attention grabbing headlines. Examples of popular sans serif typefaces are Helvetica and Avant Garde. The sans serif typeface doesn't form nice kern-pairs and is therefore hard to read .
Ornate type is any other typeface.
Gothic, Old English and script are just a few ornate typefaces. The main function of these typefaces today is decorative only, and are sometimes used as oversized drop-letters to begin a paragraph.
They are also used in place of italic or bold typefaces. When used in this manner they emphasize a word, meaning, or phrase.
Gold Disk's Professional Page with its new metric utility and screen font conversion tool lets you use any typeface in your library. These typefaces can be output to all standard dot-matrix printers and any postscript device. If your dot-matrix printer is not supported by preferences it will probably emu Lite one of the standards (Epson for instance). One word of caution on building a document based on an Amiga screen font: the document will not print correctly to a postscript device. But there is hope. If you are real clever, you will rename your font, its .font (dot.font) file and its
metric file to a standard Professional Page font name. This will allow you to fool your system into thinking it can translate the file into postscript characters. For more information on this translation read the instructions whichac- company the added metric files utility or call Gold Disk’s tech support people.
With Gold Disk’s continued dedication to product improvement I'm sure it is only a matter of time before we see virtual page compatability, rotated letters, true scalable fonts and other facilities. Professional Page is the closest thing in the Amiga's current arsenal to the current desktop publishing industry leaders. It’s only a year old and growing fast. With continued attention, it is sure to become a system to be reckoned with.

• AC- AMAZING REVIEWS On the Crafting of Programs By David J.
Hankins Welcome back!
In last month’s column, we began a discussion on optimizing programs for speed. The most logical starting point in optimizing is to determine what part of a program is responsible for its overall speed. We found this could be done using a software tool called a profiler. We ended last month's column by using a Manx C profiler (pi and p2) to profile a simple C program.
This month we will apply the profiler to a real-world example profiling the DSM disassembler Version 1.0c. The profile will help us as we attempt to increase DSM’s speed. We’ll also learn about two different types of searches, sequential and binary.
And along the way wre’ll make an unexpected discovery about what mom tells us to do.
We'll begin by profiling DSM Version 1.0c. For those of you who are interested, the profiles discussed in this column were created by profiling the disassembly of the AmigaDOS program “diskcopy.” Following the instmctions from last month’s column, I produced the profile shown in Figure 1. Note, since the source code to DSM is not available to the general public (DSM is a commercial program), you won't be able to create this profile yourself. As shown in Figure I, DSM spends
46. 25% of its time in the function “check_reloc32”. This
function checks if 32 bit relocation was performed on a given
address (the Amiga loader performs this relocation whenever a
program is run).
Check_reloc32 checks to see if the address passed to it has been relocated by searching the array "relocates" (DSM stores the address of every longword which has been relocated in the array “relocates"). If the address is in relocates, relocation has occurred and check_reloc32 returns an index to the array. If the address is not in relocates, check_reloc32 returns -1 to signal that relocation did not occur at the given address.
Figure 2 shows the function check_reloc32. As you can see, this function searches the array relocates sequentially the search begins at the first element in the array, and continues forward one element at a time until the address is found or until all elements have been checked.
I like to think of the sequential search as the “messy room search". If you have a messy room, you can’t be certain that wrhat you’re looking for isn’t in the room until you've searched everywhere. If you’re lucky enough to find the object before you’ve looked everywhere, you can stop - you've found what you're looking for. So it is with the sequential search.
Fortunately for us, other kinds of searches exist. One of these searches is called the binary search. Binary searches are ordinarily much faster than sequential searches. To use a binary search on an array, the array must first be sorted. To illustrate the use of a binary search let’s take, for example, the following array of numbers: tfnsorted Array of Numbers Number Element 0 1 2 3 4 5 6 7 8 9 10 15 7 12 99 16 11 3 5 19 21 80 Further, suppose we’re searching the array for the number 21. If we were to use a sequential search on this array, it would take us 10 tries (0 though 9) before we
found 21.
Before we perform our binary search, we sort the array from lowest to highest value. Doing so we get Sorted Array of Number Element Number 0 3 1 5 2 7 3 11 4 12 5 15 6 16 7 19 e 21 9 80 10 99 The binary search algorithm uses three indices: the "low index", the “index”, and the "high index.” The binary search begins in the middle of the array; (0 + 109 2 = 5, and so we set index to 5. Next, the low index is set to the first element in the array, 0, and the high index is set to the last element in the array, 10. To recap, we made the following initializations: low index * 0 (the first element in
the array) index = 5 (the middle element in the array) high index - 10 (the last element in the array) With me so far? Good.
We now compare the value of the array at the location stored in index with the value (in this case 21) we're searching for. The value of the array at index = 5 is 15- Since the value of the array at index is less than the desired value, 21, we know the desired value must lie at some location greater than 5. How do we know this? This must be true because, as you recall, we sorted the array from low'est to highest.
Having determined that the desired value lies at some location greater than 5, we now change our low index value to 5 - the low index marks tine lowest possible element at which we might find the value 21. We then choose a value for index which lies midway between the low and high indices. Thus index = (low index + high index) 2 = (5 + 10) 2. Rounding the value of index up results in index = 8. Let’s review the changes we've made to index and low index: low index set equal to previous value of index * 5 index set equal to (low index + high index) 2 =8 high index was not changed and remains *
10 Again we check tire value in the array at index. The value of the array at 8 is 19, still less than the desired value 21.
Making the same changes to low index and index that we made before, we get: low index set equal to previous value of index ¦ 8 index set equal to (low index + high index) 2 = 9 high index was not changed and remains =10 Once again we check the value of the array at index. We find that the value equals 21. We’re done with our search!
Note that the binary search took us only 3 tries (we guessed elements 5, 8, and 9) to find our value, whereas it took us 10 tries (we guessed 0 through 9) with the sequential search.
To continue with the previous analogy, I like to think of the binary search as tire “clean room search.” In a clean room everything is stored in its proper spot. If you’re looking for something, you can walk right up to the proper spot and find it.
So it is with tire binary search. We cleaned up tire array by sorting it, and quickly found what we were look for.
Well, enough of this digression. Back to optimizing the DSM program.
In Figure 3, check_reloc32 has been rewritten to perform a binary search. As we discussed above, using a binary' search instead of a sequential search should greatly improve the performance of check_reloc32. Note that before we can use the new binary' search algorithm we must make sure that the array relocates is sorted. I made this change in a different part of the code, and used the qsort function from the Manx library to perform the sort.
How well did we do? Figure 4 show's tire profile made of DSM after the sequential search was replaced by the binary' search. As you can see, the check_reloc32 function went from taking 46.25% of DSM’s execution time (see Figure 1) to only
2. 58% (see Figure 4) of the execution time. Additionally, the
non-optimized version of DSM took a total of 531,212.28 milli
seconds to run (see the function _main in Figure 1) whereas
the optimized version took only 304,059-91 milliseconds (see
the function _rnain in Figure 4). This represents a 75%
increase in program speed. Not bad for a day’s work.
I guess all this talk about optimization has a moral to it when you really think about it. And the moral is this: Remember when your mom used to tell you to clean your room? She was right! Next time she tells yfou to do something, pay attention it may make you a better programmer.
That’s all for this month. Next month I hope to take up the controversial topic of C-program format. Until then void main() printff "Goodbye world. n" ) ; }

Adding the Third Dimension by Larry White We've looked at many
of the animation programs currently available, and so far, they
alt have one thing in common: two-dimensional movement.
We can move an object up, down, or across the screen, but, except for a few special polyfonts in Deluxe Video and Aegis Tider, we can’t rotate into the screen. Even though we’ve simulated a 3D effect by adding drop shadows and shading, the actual movement has been limited. Before we can enter the third dimension, we have to think in 3D.
Three Dimensional Thinking What’s so special about that third dimension? The complexity it adds to your animations may appear mind boggling at first. We can rotate an object along any axis, position (he viewer at any point, and look at the scene from any direction. This means we must define what each side of our object(s) look like, where our ’lighting’ is coming from, and even the object’s surface (dull, shiny, etc.) so the computer can calculate the proper shading for each frame. The object itself may consist of many individually moving parts, such as head, body, arms, and legs; and we can
move different objects in different directions.
We can even move our viewer and zoom in and out while the objects are in motion! The calculations can get so complex that one meg of RAM may not do, and even the Amiga’s 68000 microprocessor can often use help. If you plan to do a lot of 3D animation you'll want to pay special attention to the hardware enhancement box on page 53.)
Try the Real Thing Since the phosphors in a picture tube lay on a single plane (although it may actually be slightly curved), the picture on a video or computer monitor can only really have two dimensions, height and width. Shading, perspective and other graphic techniques can create an illusion of depth in a drawing or a still graphic image. Yet, when we start moving the objects within that image, the shading and perspective must adjust with each frame or the realism will be quickly lost. This becomes even more obvious when multiple objects move, changing the spatial relationships between
To better understand the 3D world, let’s briefly step away from our Amigas, and turn on our video cameras.
(A still camera with through the lens viewing and a zoom lens will also work.)
Place a model car in front of a plain background and place a lamp to the front side. Set the camera to a close- up so the model fills about 2 3 of the screen. Start the tape, pick up the car and rotate it in various ways. (Tty to keep your hand from blocking the lens.)
Playback the tape and examine how die parts closest to the lens seem elongated and emphasized. At some angles, the car’s hood may seem distorted, and the parts closest to you will appear enlarged. Note how the shadows move as the car rotates, and how much detail there is on each side of the model.
Now place the model a long distance in front of a recognizable background. I placed mine on a railing and arranged the camera angle so that I could see a house about 1,000 feet away.
Set the focus on manual and focus on the model. Now, zoom in and out on the car and notice how the background stays in the same proportions, although you will see less of it as you zoom in and more as you zoom out. (This is because as you zoom you change the angle of view, but not the perspective of the scene.)
Now switch to autofocus and zoom to a wide or middle setting. Keep the model centered in the viewfinder and Chaim the position of tie object foe this htgfNM.

83. 21 SPINS i V Video Effects 3D a very convenient interface,
but works only with overscanned Hi-Res IFF screens in 2,4, or
8 colors.
(Bottom: Snapshot of an animation sequence created with Video Effects 3D) walk toward the car. (Unless you use a tripod on a wheels, your image might appear a bit shaky, but if you concentrate on holding the camera steady, the results should be sufficient for this exercise.) Notice how the background changes this time. Now back away from your model and watch again as the perspective changes. The closer the background is to the subject, the more these changes will be apparent. In film and video making this type of camera movement is called a dolly shot.
Now think of what would happen if the car were moving. To keep the car a constant size on the screen, the camera would need to follow the car at the same zoom position and distance. It would have to move parallel to the car, in the same direction and at the same speed.
Film and video techies call this camera movement trucking.
As the subject moves, its relationship to the lighting changes, moving shadows and highlights, and complicating matters further. As if all this weren’t enough, if you intend to place the animation over live video via genlock, you'll want to make sure that you match tire lighting to avoid having objects with shadows on opposite sides. As we enter the world of 3D animation we’ll need to keep these in mind to add realism to our computer generated videos.
The next time yrou watch television, pay special attention to the relationship between objects (people, cars, props, etc.) and the background during various scenes, Notice how they move relative to their background. Pay attention to camera motion and the sharpness (or lack thereof).
Entering the Third Dimension Let's start by moving a 2-dimensional object around in a 3-dimensional world. This technique is extremely useful for producing effective titles.
You can create a title screen using almost any paint or titling program that saves your art as an IFF file. Before you start, check which resolutions and screen sizes your animation package supports.
Also check for any special limitations on palette size or selection.
Two 3-D animation programs are Video Effects 3-D (InnoVision Technology) and AnimatiomEffects (Hash Enterprises). AnimatiomEffects can use any resolution IFF picture including overscan. You can even use HAM in low or medium resolution modes (although you can't mix resolutions at the same time). Personally, while I found this program very effective, I was not impressed by the user interface.
However, I expect an updated version soon, which claims a vastly7 improved user interface. Video Effects 3D has a very’ convenient interface, but works only with overscanned Hi-Res IFF screens in 2,4, or 8 colors. Both programs can create dramatic animation effects, but the actual processing time for your final image can be rather long, overnight is recommended.
I needed a short title sequence for a videotape of a roundtable discussion sponsored by Popular Photography Magazine. I wanted to use the actual magazine logo and a special logo for the “roundtable series” and have the title sequence blend with the live video at the end. I decided to try Video Effects 3D.
BeGinners Have you ever seen a GURU MEDITATION ALERT or a TASK HELD REQUESTER telling you that a program has crashed?
If you had GOMF in your system, you would have been able to remove the program that caused the error, and you may not have had to reset your computer!

Let’s Make Some Titles You can create the titles using any titling program (such as TV'Text, or Aegis VideoTitler) or using any paint program that can save the title screen as an IFF file. I chose to start with a high contrast, black & white copy of each logo, digitized them using DigiView. Just as I was getting started, a package arrived containing DigiView 3-0. In addition to supporting overscanned HAM images, DigiView has a special mode for digitizing just this type of “line an".
The program operates like version
2. 0; but specifying this mode forces all colors either black or
white; producing a very sharp Hi-res copy of the artwork.
When using this mode with overscan, I had some difficulty, so I decided to keep to standard screen. I could change it to overscanned later by loading the logo as a brush on an overscanned paint screen.
To prepare the digitized artwork for animation, you can use an image processing program such as Pixmate or Butcher, and or a paint program such as DigiPaint or Detuxe Paint II. Make sure to set the proper resolution and screen size for your animation program. Deluxe NEW VERSION !!!
It's amazing! Now, you can actually save data AFTER a program has crashed! (Even after a total lockup) We call it the GOMF BUTTON.

This is not the standard Dpaint overscan, but can be entered on the “page size" menu by specifying width and height.
For multiple graphics to appear simultaneously, make sure to use the same palette. If you don't, objects on the screen will suddenly change color as new objects are introduced in the animation sequence. Although you must define the entire screen for Video Effects 3D, during the animation, you can crop into the graphic screen and treat any part of the screen as if it were an IFF brush. If you plan to genlock over live video you'll need to watch where you place color 0, since this area will be replaced by the live video.
3D Effects Video Effects 3D requires at least 1 megabyte of PAM but 1.5 Meg is recommended. Depending on which Amiga model you have and the type and amount of expansion ram, you may need to change the stack and execute a SloMemLast command in your startup- sequence.

Other Offerings: Deluxe MIDI Interface. Simply the best you can buy! Only $ 95 TTL monitor interface $ 99 Before you run the program, format 2 disks. Label one “Script Disk" and the other “Play File Disk". One minor drawback of this program is that you can't format with the program running. Also, if the program needs the disks it will not prompt you. Since the processing can take hours, it might be some time before you discover your error and have to start over, a very frustrating situation.
The basic principle of this type of animation is simple. You define the first and last frame of your sequence, and a few specific frames in between. You then specify what happens to your object between these “keyframes"; and specify how long the sequence should run. Your Amiga will then calculate each frame of the sequence and record the frames as an IFF Anim file for playback.
When you mn Video Effects 3D you'll get a slightly different type of Amiga-user interface. A screen of requester-type boxes and a round yellow mouse pointer will appear. There are no pull-down menus or Amiga Hotkeys, but if you position the pointer over one of the requesters a block of text will change to explain the current requester no clicking required. Click on the requester and the program goes into action.
First, define a script (or specify an existing one to edit). Then select various IFF pictures as your objects. Each object will form a separate track which will contain the motion of that specific object.
Several tracks can be running simultaneously allowing you to manipulate many objects in the same scene.
The 3D Universe Before we can even begin to animate we need to take the subject and place it in a 3D universe. A standard monitor screen can be thought of as a two dimensional grid. Conventionally we call the screen width the X axis, and the height the Y axis. In many of our 2D animations we used X-Y coordinates to specify the screen location of our objects.
We can specify the movement perpendicular to the screen as the Z axis.
We can specify the location of the object on the screen using only the X and Y coordinates. Changing the Z coordinate will move the object towards or away from the viewer.
Now we can turn the object in 3D space. If we specify ‘tumble’ the object moves in much the same way as a log rolling down a hill. You can see that the object is rotating on an imaginary pin placed along the X axis. If the pin were along the Y axis, the object would ‘Turn’ like the page of a book. Placing the ‘Spin’ is equivalent to turning a page upside down then rightside up. (Our imaginary pin would be pointing directly out of the screen). You can specify any number of tumbles, turns, or spins, and even have an object perform more than one at a time. For example, making an object tumble and
spin as it approaches the viewer can be a very dramatic way to introduce a tide.
By specifying the center of rotation for your object, you can get various effects of tumbles, turns, and spins. If you moved the center of rotation to the left edge of a block of text a turn effect would make the title move like a hinged door.
It’s often difficult to picture exactly what an effect will look like. I often reach for a small block of wood and turn and tumble it before instructing tire program to proceed. You can use a 1 4 screen wire-frame mode to preview an action between keyframes.
When you’ve programmed all your objects (tracks) you can place your playftle disk in the proper drive and begin rendering. Your Amiga will be tied up for quite some time, so be patient and prepare to do something else. When rendering is finished you can use the player program to view your work.
The resulting animation is usually amazing. Don’t be surprised if the result is not exactly as you predicted. Even the most expensive animation systems can produce unexpected results (although usually with much faster turnaround time), and sometimes these results are even more spectacular than you expected.
Video Effects 3D has a few more tricks we haven’t discussed which can enhance the 3D effect, like adding drop shadows to your animation. You can even use the program to extrude a two- dimensional logo into a three-dimensional one (as if it were carved from a block of wood) then use the 3D logo in your animation!
This brings us to the topic of the next installment 3-dimensional objects and the methods for creating them in your computer (including ray-tracing programs such as Stiver and Sculpt-3D).

The number of calculations in a 3D animation or ray trace can be astounding- On my A500 with 1 meg, a fairly simple object can take over 24 hours to be rendered at the highest resolution with anti-aliasing activated. I’ve added an expansion chassis from Pacific Peripherals which can accommodate 2 A2000 boards.
In one slot I’ve put Commodore's new 8 megabyte board (populated with 2 meg of fast RAM) which has helped speed things up a bit (I've already reserved the other slot for a video frame grab board - such as NewTek's Video Toaster or Mimetics’ board (both expected soon)).
I've been told that the new 86020 and 86030 chips plus math coprocessors can cut the calculation time dramatically, often to just a few' hours.
Not all software can utilize the coprocessing; if you choose this route make sure that the program versions you intend to use support the processor and coprocessors.

THE BUGS & UPGRADES COLUMN BUG BYTES by John Steiner This month’s list of bugs and upgrades begins with a mystery. A friend and i have the Amiga 2090 hard drive controller card, and we have had some trouble with overscan mode and hard disk access. We have also noticed a thread on People Link, regarding others having similar problems.
If you are a regular reader of Bug Bytes, you may recall that there have been a couple of upgrades to the software that comes with the 2090. The latest of these upgrades solves the problems my friend and I have been having. Problems occur in overscan mode, and they typically manifest themselves as irregular read write errors on the hard disk. It seems that information on the drive can be damaged, as 1 have been forced to reformat the disk on more than one occasion when the problem occurred.
While reading the People Link message base the other day, I noticed several messages from people still having trouble with hard drive errors in overscan mode. In fact, several even had problems with high resolution 640x400 mode in some software packages. The commonality in the problem relates to SCSI based hard drive systems, and there still seems to be a problem with drive access for those using SCSI drives. The drives used by my friend and I are ST- 506, the IBM-type hard disk.
1 hope not too many 2090 owners are unable to use the Amiga in hi-res and or overscan mode. If you have a 2090 and a SCSI drive, ! Am interested in whether or not you are having problems in high resolution or overscan modes.
Comments left on People Link usually say the problem occurs due to the behavior of the Amiga bus when the display is in hi-res, four bitplane mode.
In this mode, chip memory’ is not available to the CPU or to a DMA device during the unblanked display period. If the CPU or a DMA device tries to access chip memory, it is forced to wait until the horizontal blanking interval the only time chip memory is available. For each scan line of 63 microseconds, horizontal blanking lasts about 13 microseconds.
The 2090 disk controller is a DMA device, and therefore must deal with the above situation. The expansion software that comes with the 2090 evidently has been modified well enough to handle the ST-506 type drives, but from the above reports, it seems there still is a problem with SCSI-type units.
If you have a 2090 card and a SCSI drive in your A2000, please drop me a line via Amazing Computing, or at either of the nets listed below. Let me know whether or not you are having problems in high resolution or overscan modes. Please list the software packages you are having problems with; it seems that not all software works improperly with the SCSI hard drive 2090 combination. Also, several people with memory expansion boards were not having any problems if they used FastMemFirst as the first command in the startup sequence. There could be many other variations to this problem, so
please list all peripherals you are using.
A few weeks ago, I purchased Deluxe Productions from Electronic Arts and immediately had a problem with hard drive access with the program. The program runs in high resolution overscan mode. A call to EA technical support brought some assistance primarily the names of Dproductions’ developers at Associated Computer Services. When problems occurred, I didn’t realize they might be related to the FastMemFirst problem, but now I am convinced of it.
The technical support staff recommended that since I have expansion memory, I should put FastMemFirst in the startup sequence file before BindDrivers. This action cleared up the problem immediately.
On the subject of Deluxe Productions, I also noticed some minor problems in the documentation. One problem dragged me through several Guru visits.
The manual's AppendLx includes an excellent section for Dpaint II users interested in making the most of using Deluxe Paint with Deluxe Productions.
There is one error, however. The manual states that you specify the page size with the Page Size command in the pictures menu. It further comments that you can select Standard (640x400), Full Page (640x480), and Full Video (672x444). Full Video is recommended for pictures created in Deluxe Productions. Actually, Full Video mode in Deluxe Productions is 704x480. A pair of boxes is available where you can type in the exact page size, if it is not listed.
I had not really noticed the difference between what the documentation said about page size, and the size that Deluxe Paint listed; I simply chose Full Video. The results: pictures created for Deluxe Productions only occasionally loaded or were accessible. The machine visited the guru, and other strange or unusual symptoms cropped up. When I discovered the discrepancy in screen size, I edited the pictures to the 672x444 format that Deluxe Productions recommends. The program worked flawlessly.
By the way, the manual also states that Deluxe Productions accepts a picture larger than 672x444, but will not display any larger image. Based upon my own experience, this statement is evidently not true. At least, Deluxe Productions does not reliably accept a Full Video image from Deluxe Paint.
Tire FlickerFixer board from MicroWay is an exceptional product. The board is a high resolution display adapter that provides a 640x400 non-interlaced (flickerless) high resolution mode. The hardware requires a VGA or multi-sync monitor, and provides a beautiful Amiga image in any resolution mode. The latest version of the fliekerFixer is now compatible with the European PAL versions of the Amiga 2000.

program, has recently been released. A new feature is the
ability to read and use script files.
Occasionally, though, the program cannot find a script file. ACCESS! Seems to have trouble getting the actual drive location from the window that comes up with the on-screen gadget. Using the pull down menu item to get a script shows that die program is looking on the wrong drive. Change the drive location to the one you want, and the gadget finds die proper drive, ACCESS! Is on most public domain bulletin board systems.
GOMF from Hypertek Silicon Springs has been upgraded to version
3. 0. GOMF helps die Amiga recover from system Guru messages. The
latest version of GOMF can be purchased with the GOMF Button,
a hardware attachment installed under the Paula chip. A small
wire with a pushbutton is brought outside the Amiga, so it can
be accessed after a Guru message. When die system locks up,
the button releases the errant task and unlocks the machine.
The GOMF 3.0 Button with software retails for S69.95, and the
GOMF 3.0 software- only is 34.95. Registered owners of
previous versions can upgrade to the hardware version for
$ 30.00, and the software-only upgrade is $ 10.00.

AMAZING REVIEWS_____i Amiga 2000 Hard Drive Roundup by Sheldon Leemon Last year's 20 megabyte hard drives cost over 51000, and ran only about 3-5 times as fast as a floppy disk.
This year, you can purchase a 65 megabyte hard drive system for the A2000 which runs from 5 to 10 times faster than last year's models; and sells for under S1000. And soon, you’ll be able to boot your computer directly from the hard drive, instead of from a Workbench disk.
The speed increases have been made possible by the Fast File System, a software change that was one of the main agendas of Workbench 1.3 (which we all fervently hope will be available by the time this is printed). We have already detailed the optimizations used to increase the speeds in our the hard drive roundup of AC V. 2,6. To use the FFS with a hard drive, you must copy the FastFileSystem file to the L: directory of your boot disk, change a few entries in the Devs:Mountlist file, and then reformat the drive.
Not only does the new file system increase speed many times, it also increases capacity slightly, since all 512 bytes of each data block are used for data, instead of the 488 bytes available under the old file system. This means an extra 50K of storage for each 10 megabytes of drive capacity. Although it's technically feasible to use the FFS on floppy disks, it’s still quite cumbersome, and the speed gains are not anywhere as dramatic as those achieved by hard drives. Kickstart 1.4 should overcome both these limitations; and it will include the FFS as the default file system for both
floppies and hard drives.
Kickstart 1.3 also offers autoboot- ing. In fact, the only difference between Kickstart 1,2 and 1.3 is the autoboot code added to 1.3. Autoboot allows the computer to start up from devices such as hard drives, network cards, and even Commodore's new recoverable RAM disk, without having to have a floppy in drive dfO:. This means that only hard drive owners who want to autoboot will benefit from getting the new 1.3 ROMs.
But just getting a new Kickstart ROM will not automatically cause your hard drive to autoboot. The hard drive interface card must include boot code in ROM. None of the controllers currently sold come with these boot ROMS. Some controllers have sockets on the board, just waiting for the new Kickstart ROMs to be distributed. Even some of the interface boards which don’t have these ROM sockets may be retro-fitted to enable auto-booting. Since the FFS must still be read from a disk before a Fast File partition can be mounted, the boot partition must be formatted with the old file system.
Therefore, most autobooting drives will have at least two partitions, a small boot partition and a large Fast File partition.
There are a number of reasons for today's lower prices. The Amiga 2000 made it possible to install a hard drive internally, thus eliminating the expense of an external case and power supply.
The 2000's internal expansion capabilities have also made it easier for manufacturers to enter the Amiga hard drive market, since they need only produce an interface card and driver software.
Increased competition between manufacturers has tended to move prices lower.
Finally, the market prices for hard drives, particularly the SCSI hard drives often used in the Amiga, have decreased while capacities have increased. As a result, Amiga owners wall no longer have to pay twice as much for hard drives as owners of IBM compatible systems do.
Amiga SCSI drive systems cost only about $ 150-5200 more than the IBM ST- 506 drive systems, and mounting one on the Amiga costs about the same as mounting a fast SCSI drive in an IBM.
To DMA or not to DMA The interfaces tested use two general types of data transfer schemes DMA and processor-con!rolled I O. In processor-controlled I O, the 68000 microprocessor is used to read each byte of data from an I O register, and then copy it to a memory' buffer. Direct Memory Access (DMA) transfers, however, don't require the processor to fetch each byte. DMA devices can write directly to a memory buffer within the Amiga, without processor intervention.
Normally, DMA devices and the 68000 alternate their control over the bus, so that neither interferes with the normal- speed operation of the other.
Theoretically, DMA devices can transfer data without slowing down any of the processor’s normal tasks. This approach can lead to significant performance improvements in a multi-tasking machine like the Amiga, where time saved by one task can tie used by another. In fact, it's just this kind of “coprocessor" approach that make Amiga graphics acceptably fast within a multitasking context.
Unfortunately, a number of re?'
World conditions prevent the user from getting DMA data transfers “for free". For one thing, each transfer requires some processor overhead, as the driver tells the DMA chips how much information to move, and where to transfer it. After the data has been moved, the system, must be informed that it has arrived. Therefore, a DMA interface demonstrates its greatest speed when moving large amounts of data. The overhead involved may make it less efficient to use DMA to move small amounts of data than plain old processor-controlled I O.
Another potential problem with DMA is that there are onlv so many bus cycles to go around. Normally, the 68000 processor controls the bus half of the time, and the other half is available for DMA devices. Unfortunately, the hard disk isn't the only device competing for the bus. The display processor, the blitter, the sprites, the audio channels, and the floppy disk drives all use up part of the available system bandwidth, When die normal Workbench screen is displayed, there is usually enough time for each device to do its job without interfering with the odiers. But when the system is
displaying a liigh- resolution screen with 8 or 16 colors, and an overscan width of 700 or more pixels, system resources are stretched a bit thin, even without a DMA hard drive making additional demands. In such situations, DMA hard drive interfaces are likely to slow down significantly, and possibly even develop timing problems.
Two things most people expect from DMA hard drive interfaces are speed and concurrency. But just because an interface uses DMA transfers doesn't mean that it is faster, or better integrated into die system than one that doesn’t. A lot depends on the driver software.
For example, in our first hard drive review, we stated that non-DMA drives tended to affect multi-tasking, as seen by the jerky mouse while the drive was being accessed, and only one program at a time being able to access the drive (one DIR command would have to wait until the other had completely finished before starting its listing).
However, neither of the two non- DMA drives tested here exhibited those symptoms, while some mouse jerkiness was evident with the Pacific Peripherals DMA controller (though the company claims it is remedied in the latest version of the software). It is best, therefore, to be guided by a hard drive system’s performance, rather than by buzzwords. It makes no more sense to base your hard drive buying decision on the letters DMA than it would to base your computer buying decision on the letters IBM.
About the Tests Each interface was installed in the same Amiga 2000 with the same 63 megabyte hard drive. The drive was formatted each time, and partitioned into three logical drives of 20, 33, and 10 megabytes each. The partitions were partially filled using the LV Backup program to restore several megabytes worth of files. The system was nan with each interface for at least a week, to make sure that no serious problems arose in normal operation.
Several benchmark tests were run using each interface. The first was the ever-popular “Diskperf program that we used in the previous hard drive comparison, Trfis program times various operations, including creating and deleting files, scanning directories for file entries, moving the read head (seeking), and reading a olock of data. It also measures the speed at which the drive reads and writes data blocks of varying size (from .5 Kilobytes to 32 Kilobytes). It also measured the total time it took for the Diskperf program to run; to provide an overall indication of how quickly the drive
performed the tasks. The results of the Diskperf test are shown in Table 1.
Running Diskperf by itself doesn't indicate how a drive interface will perform in a multi-tasking environment.
Therefore, other tests were devised. The first measures the drive performance under “he avy DMA” conditions.
Fot this test, two programs were run in the background while Diskperf was run. The first program displayed a 704 x 464 overscan picture with 16 colors. The second program, Sonix Play, played a 4-voice music score. Although this is not a typical example of how most people use their Amiga, it isn’t really flickerFixer eliminates your Amiga 2000’s interlace flicker and visible scan lines. The result; superior quality color or monochrome graphics and text for a full range of demanding applications, including CAD, desktop publishing, graphics, animation, and video.
FlickerFixer fits into the Amiga video slot, is fully compatible with all user software, and does not modify the standard Amiga video signals. The board also upgrades the AMIGA 2000 with a flicker free 4096 color palette, has an overscan mode that features a screen size of 704 x 470 pixels and drives most of the popular PC Mjltiscan and VGA monitors, including the NEC Multisync and Mitsubishi XC1429C.

(508) 746-7341 01-541-5466 extreme. Some of the flashier video
presentation programs combine large overscan displays with
music; and the presentations created with these programs
often require a large amount of data to be read in almost
continuously off of the disk. The results given by the
Diskperf program when run with sound and graphics in the
background are shown in Table 2, A third Diskperf test was
designed to show how processor-intensive tasks affected
disk performance, and vice- versa. For this test, a variant
of Perry Kivolowitz's RAMspeed program was run continuously
in the background while Diskperf executed. This program
tests the speed of expansion RAM versus Chip RAM by timing
a large number of processor memory move instructions.
Since this program continuously uses the processor (without waiting for user input), it shows how the drive interface handles competition for processor time.
And since it times a fixed number of operations, it also can be used to see how the drive activity affects a concurrently running application program. The results of the Diskperf tests, and the Ramspeed timings, are shown in Table 3- Since benchmark programs like Diskperf tend to test artificial situations, we also performed a series of tests designed to correspond more closely to the operations real users routinely perform. The first test measured the time it took to copy an entire disk full of files to and from the hard drives. The disk in question was the Omega 6 version of Workbench 1.3,
with 178 files in 21 directories, some 714 Kbytes in total.
The next test measured the loading time for loading an 84626-byte high-res overscan picture into Deluxe Paint II. This test was something of a ringer, as it was designed to demonstrate an interesting quirk of the Commodore 2090A driver. Since Dpaint has no timing facilities, this timing was done with a stopwatch (the other timings were done with the same "Time" program used in the previous review). The final test measured the time it took to load and execute a 100,000 byte dummy program (100K of data and an RTS instruction).
All tests were run using the Fast File System from a pre-release version Omega 6 of Workbench 1.3. Although Fast File was not quite released at test time, it is so much faster than the old file system that it seems unlikely many hard drive owners will stick with the original system once the new one becomes available. Under these circumstances, we felt that testing the interfaces with the old file system wrould render this comparison obsolete as soon as it was printed.
Since the original round of hard drive comparisons included other devices such as the dfO: floppy drive and the RAM: device, we decided to include the newest virtual drive, RAD:, the recoverable RAM disk from Workbench 1.3. Note that the times shown were for a RAD: drive formatted using the Fast File System. That’s right, to use FFS on RAD:, you must first format the RAM drive.
The speed difference is fairly dramatic.
Using the old file system, RAD: is slower than most of the hard drives tested here.
Using the FFS, it’s quite a bit quicker.
Anomalies, Inconsistencies, and Mysterious Occurrences Considering the preliminary nature of the FFS, and the relative newness of 2000 hard drive systems, surprisingly few problems were encountered. A couple of boards seemed to function inconsistently when used with the Micron 2 meg expansion board, but only when the FastMemFirst program was run before the drive was mounted.
Great Valley and Supra are both making minor hardware changes to eliminate this problem. We also ran into trouble trying to run the JDK Images’s Pro Video Plus program from the hard drive. None of the interfaces could successfully load the program more than 50% of the time. No problems were encountered with loading and running any other programs.
Test Summary As expected, the DMA controllers (Commodore 2090, Pacific Peripherals Overdrive, and Supra A2000 interface) showed somewhat faster results from the Diskperf program than the programmed I O controllers (Great Valley Products Impact card, and C Ltd.), particularly in the large buffer reads. A look at the overall time Diskperf took to execute in each case show's that the differences are not all that great. The Supra and Commodore 2090A interfaces turned in the best times, but the processor-controlled C Ltd.
And GVP boards took only 18-23% longer to complete the task. Pacific Peripherals' Overdrive board took the longest, probably due to its rather slow writes.
When it came to multi-tasking, however, the results were much different.

Concurrently, the Commodore 2090A drive became much slower than any of the others. Although the two other DMA cards, the Overdrive and Supra interfaces, didn't slow down anywhere near as much, both caused the music player program to play the song slower than normal. Also, the Supra unit caused the overscan display to "tear momentarily, several times during the course of the test. No processor-controlled C Ltd. Or GVP board exhibited these problems.
The Great Valley Impact card clearly came out the best in this test: it took twice as long to complete die Diskperf program as in the previous test. The others took anywhere from 2 1 2 to 7 times as long.
The results of the processorintensive test also fall into line with our observations about DMA and processor- controlled interfaces. The DMA boards were hit hardest during short reads. In the I 2K buffer test, both the 2090A and Supra cards went from 60 Kbyte second reads to about 8 Kbytes second. In the larger buffer tests, however, the DMA cards slowed down much less, and slowed the RAMspeed task down much less as well. The processor-controlled GVP interface was much less affected during short reads, but slowed the other task down more, particularly during the large reads and writes.
The miscellaneous tests in Table 4 put these other tests into perspective. As the other tests show, there is a maximum 20% speed difference between the various controllers for tasks like copying files. Thus, while tire fastest controllers loaded a 100,000 byte file in a bit over 71 10s of a second, the slowest took a shade over 1 second. Not exactly what you'd call a monumental gap, particularly when you consider that the fastest of these boards are nearly half as quick as the RAM drive.
Note that the results given here are by no means cast in stone. All of the hard drive interfaces tested here are fairly new, and changes to the driver software are as inevitable as death and taxes. Such changes can cause big variations in the test results. An early version of the Supra software read a maximum of 50 Kbytes per second; the latest version's top speed is almost 6 times faster.
Conclusion The good news is that all hard drive systems tested performed much better than those in our first test. Not only were they much faster (thanks to the new file system), but they performed more reliably as well. Not once in over 2 months of testing did I get the dreaded “Drive dhO: has a read write error" or “Not a DOS disk in unit 1” requesters.
The previous generation of drives were much more fragile, and prone to failure in the course of normal operation. The improved reliability of the drives and the availability of good backup programs like LV Backup means that the prudent Amiga owner need no longer fear catastrophic data loss should he switch to a hard drive.
Picking any one of these products, however, is a complex task. Even if you take the rather simplistic approach of picking the fastest drive interface, the question becomes, fastest under what conditions? Though the Diskperf results in Table 1 suggest that the Commodore 2090A is the fastest controller, the results in Table 2 shows that under certain conditions, it's the slowest.
And speed is by no means the only factor on which to base your decision. Price, features, and manufacturer support must be considered.
Compatibility is another very important issue. Though most manufacturers test as many configurations as they can think of, there are bound to be some combinations of memory boards, processor accelerators and emulator boards that they haven't tested. This makes it important to buy your hard drive system from a dealer who will make sure it works properly with your equipment, or exchange it for one that will.
Despite the difficulty, if pressed to make a decision, I’d probably pick either the Supra or Great Valley Products Impact board. The Supra interface is one of the fastest tested, and was among the least affected by the DMA and processor tests. Its price is among the lowest.
The installation software supplied with the board makes the drive easier to set up than any of the others (though most of the companies are in the process of enhancing their installation software).
The board has sockets for autoboot ROMs, so t should be easy to upgrade once 1.3 Kickstart ROMs become available. The most significant negative factor was the minor quirk mentioned in the discussion of the graphics and sound test. Considering the newness of the product, it seems likely that such problems will be ironed out when the software undergoes fine tuning.
The Great Valley SCSI interface was by no means the fastest one tested, but it was he most consistent. Because its performance figures changed so little during the graphics and sound tests, this board would be a good choice for those who do a lot of presentation graphics and video work. Like the Supra card, it includes the ROM sockets needed for autobooting. Great Valley makes this interface available in a number of convenient formats expansion RAM interface combinations, hardcards, and a 500 hard drive expansion RAM combination. Some of the hardcard configurations should be quick, since
they use fast Quantum and Conner drive mechanisms.
In the end, though, you’ll have to make your own decision. There are a number of reasons why your choice might not agree with mine. Some people won’t mind paying for the warm, fuzzy feeling they get from buying a genuine Commodore product for their 2000.
Others will like the convenience of mounting their own 3 1 2" hard drive directly to the Overdrive board to custom-make a hard card. And for those who plan to buy the Dest scanner or laser Xpress printer, the C Lid. Board would be the natural choice for a hard drive interface. Whichever you select, rest assured that you'll be getting your money's worth. With a fast hard drive in your system, you will be constantly reminded of what a powerful personal computer the Amiga really is.
The Commodore 2090A Hard Disk Controller The 2090A is the updated version of the 2090, the original DMA hard drive controller for the Amiga 2000. The only real difference between it and the 2090 is that the 2090A has a couple of sockets for the ROMs needed to autoboot the system from the hard drive (provided, of course, that you have the 1.3 Kickstart ROMs). Though the ‘A’ version of the controller was not yet available when this review was written, it is in production, and should soon become the official Commodore hard drive interface product. Those inclined to purchase a Commodore
controller should note that at present, Commodore has no plans to retro-fit an auto-booting capability onto the earlier 2090 controller. Owners of the 2090 card may be able Lo add autoboot- ing capabilities through third party products, however. Both M.A.S.T and Michigan Software are planning to market static RAM modules that you can boot from, for example.
The 2090A is unique among the controllers tested in that bodt SCSI and ST-506 interfaces come standard on the board. It allows you to connect up to two IBM-style drives and seven SCSI devices up to your Amiga 2000. This much flexibility doesn’t come cheap, however. The 2090A lists for S399, more than any of the other interfaces tested.
For purposes of comparison with the other SCSI controllers, only the SCSI interface was tested.
The 2090A comes on a full-sized A2Q00 card, about 4 1 2" high. The component side of the controller card includes a 50-pin SCSI connector, and two ST-506 drive connectors. The mounting bracket on the edge of the board carries a 25-pin connector for external SCSI devices. Physical installation of the hard drive system requires you to mount the drive in either a 3 1 2" or 5 1 4" drive bay, plug the power cable into the drive, connect the drive to the interface via a 50-pin ribbon cable (not included with the 209QA), and plug the drive into one of the 2000's 100-pin slots.
Software installation is relatively simple. The disk that comes with the controller hardware contains an installation program that can be run from an icon. This program takes you through low-level formatting, and installs the software needed to boot die drive on a copy of your Workbench disk. After the installation program finishes, you must run the AmigaDOS FORMAT command from the Cli before you can store any information on the drive. The entire installation process is well documented in the manual.
Although the installation program that comes with the controller is fairly good, it has a number of significant limitations. The program’s format is more like the old-style PC applications than Amiga applications. It asks you a number of questions, one after the other, and has you type in the answers, rather than the normal Amiga procedure of setting up text gadgets and allowing you to fill each one. This means if you make a mistake, you can’t go back to the previous question. Also, the installation program asks you to choose the drive type from a list which does not contain several of the
more popular SCSI drives. For drives like the Seagate 277N, you must fill in the number of heads, tracks, and sectors per track. While this information usually comes with die drive, it isn’t the kind of thing the average user knows.
Nor does the software help much with partitioning the drive. The installation software sets up a default partition (DH2: for SCSI drives), but if you want to divide the drive into additional partitions, you must edit the DEVS:Mountlist file.
Here, the information on the number of heads and sectors per track is critical if you don’t know it, the drive won’t format. Since DH2: becomes the boot partition when autobooting is enabled, it cannot be formatted with the Fast File System. Therefore, if you use the FFS on the 2090A, you’ll have to learn how to partition the drive.
Although ! Have the 1.3 Kickstart ROMs, the 2090A didn’t actually boot my system from the hard drive automatically, That’s because the 277N drive takes so long to warm up that when the controller looked for the drive, it wasn’t ready yet, and the "Workbench 1.3” prompt screen appeared. A warm reset (CTRL-AMIGA- AMIGA) allowed the boot process to succeed, however, and later versions of the boot ROM will probably may wait longer before timing-out. It should be .

Amiga is a registered name of Commodore Amiga, Inc. noted, however, that with the version tested, die boot process took quite a long time. The screen stayed white for almost 30 seconds before I got the Workbench prompt, and for a while, I was afraid that I'd plugged something in the wrong way and fried the computer.
The 2090A performed quite reliably during testing. Prior to this reviewc I had a number of bad experiences installing SCSI drives with the Commodore 2090 controller. The early versions of the driver software were extremely unreliable, particularly when the controller was used with the faster SCSI drives. Read write error messages turned up quite frequently, and the drive absolutely refused to load l6-color high- res pictures from Deluxe Paint U. I was almost ready to give up on it completely, when I received a new version of the driver software, dated May 5- This version completely
eliminated the read failures.
Although the 2090A no longer fails in situations where the timing becomes tricky, it still doesn't perform very well in such cases. Normally, this controller is one of the fastest ones tested. But when a high-res, 16 color screen is displayed, the transfer rate drops to 15% of normal, or less.
While the new version of the driver no longer fails when trying to load a 640x400x4 picture from Deluxe Paint n, it takes an extraordinarily long time to do so. As Table 4 show's, it took the 2090A almost a full minute to load an 80K file, about ten times longer than the other drives. This particular problem seems confined to Dpaint II, however; the 2090A loads the same picture in other paint programs with no trouble.
At this point, there aren't many compelling reasons for the average user to select the 2090A. For those who only want to connect SCSI hard drives, the 2090A is about 40% more expensive than similar SCSI adapters, and offers no real substantial advantage. Users who want to hook up ST-506 drives can buy a Supra SCSI interface with an ST-506 to SCSI adapter for about the same price. Such adapters improve the performance of the ST-506 drives by providing a RAM buffer which increases transfer speeds, and RLL data encoding, which increases the storage capacity by 50%.
For those who don’t mind a bit of extra expense, however, the 2090A is about the fastest controller available, at least in the Workbench environment.
Another attraction is that it's made by Commodore, and is therefore tikely to be compatible with the widest range of Commodore and third-party peripherals.
For those who rest easier knowing that their 2000 contains only genuine Commodore parts, the 2090A is a reasonable choice.
Commodore 2090A Hard Disk Controller Suggested Reta il Price S400 Commodore Business Machines 1200 Wilson Drive West Chester, PA 19380 The Great Valley Products Impact SCSI RAM Controller Although Great Valley Products is a relatively new company, it’s not unfamiliar with the Amiga market. Gerard Bucas, the company's president, was formerly a Vice President of Engineering at Commodore's West Chester offices.
Great Valley’s first product is a unique combination RAM expansion SCSI interface board for the Amiga 2000.
Originally, the board was to have come populated with 1 megabyte of memory in 256K RAM chips. Unfortunately for GVP (and just about everybody else), the introduction of their board coincided with a shortage of 256K RAM chips that forced them to re-think their strategy.
They now offer the controller in two flavors, one that holds up to 2 megabytes of the more cost-efficient megabit chips (256x4), and one that holds up to 1 megabyte using 256x1 chips. Both boards are sold without memory chips, so that you can add the memory yourself, either now, or later, when the price of RAM (hopefully) drops. We tested the 2 megabyte version, with no memory installed.
The Impact board is solidly built and nicely finished (the ends of the edge connector have been beveled for easier insertion, and the 25-pin external SCSI connector is riveted, as well as soldered, to the board). ’Hie sixteen sockets for RAM chips line up against the top edge of the board, and two jumpers are used to set the RAM configuration. The card also has two sockets for autoboot ROMs, though the ROMs were not available for testing at the time of the review, A 50- pin SCSI cable is included for connection to an internal drive.
The board comes with both a printed manual and an installation disk.
The manual is extremely thorough, covering the mechanical installation of the controller and the hard drive, the software in.tialization process, RAM installation, multiple SCSI devices, and setting up various hard disk partitions.
The manual contains a lot of nice extras like a description of the elements of a Mountlist entry, and pin-outs of both the 25 and 50-pin SCSI connectors. It is also is the only one I've seen that warns about shutting down a drive too soon after drive activity. This is a warning well worth heecling, since a delayed xvrite may occur a few seconds after a longer write has finished. If you turn off the power before all write activity has ceased, the results may be as disasterous as pulling out a floppy disk before the red light goes off corruption of the disk, and loss of all the data on it.
Initializing the disk and creating a boot disk are done using script files, activated by icons from the Workbench.
In the current version of the software, however, the Devs:Mountlist file is set up for one or two 20 megabyte partitions only. Any other configuration will require some editing of the Mountlist file. Setup follows the normal AmigaDOS procedure. Do a low-level format (if desired), run the B1NDDRIVERS program, the MOUNT program, and the FORMAT program to prepare the drive for use by AmigaDOS, The Great Valley board is the only other besides Commmodore's own to store the hard disk driver program in the Expansion drawer, and use BINDDRIVERS to load it. In the future, Great Valley plans to
include a comprehensive installation program with an Intuition interface, that allows you to interactively set initialize your drives.
Advertisements for the Impact board refer to it as “DMA SCSI", but that description is somewhat misleading.
Company officials explained that the board “DMAs into the on-board memory cache". In plain English, that means the card has it’s own memory buffer, which is used to store information as it comes off the drive, before being passed to the Amiga via “processor-controlled I O".
While the on-board cache undoubtedly speeds things up, the term “DMA” is more commonly understood to mean that the controller moves information directly into the Amiga’s memory space, not into its own memory buffer.
Although not the fastest controller in all situations, the Impact board’s performance was quite respectable overall.
As explained in the overview section, DMA transfer has costs as well as benefits, and the GVP board was obviously designed to avoid the penalties incurred by DMA controllers when competing for scarce system resources.
While it was about 25% slower than the DMA controllers under normal Workbench conditions, it proved faster, on the whole, than all of the other controllers tested with high-res graphics and sound running in the background. This consistent level of performance makes the board a natural choice for those who use the Amiga to run elaborate graphics and sound presentations. In addition, the single-slot RAM expansion and SCSI controller should appeal to those who wish to leave some room in their 2000 for future expansion.

(800) 782-1841 Pacific Peripherals Overdrive Board The OverDrive
board from Pacific Peripherals was the first SCSI-only DMA
alternative to Commodore’s 2090 to appear for the Amiga
2000. Although it occupies a full-size board that's the
same size as tire 2090A, the components are all packed into
the left side of the board.
The bare right side of the board has four holes that can be used to mount a 3 1 2" hard drive directly to the controller card.
A hard drive power cable is also provided on the right side of the board for this purpose. The Overdrive was the only one of the interfaces tested that was designed specifically for use as a hard drive card, keeping both of the extra drive bays free for other drives.
The current version of the OverDrive has no provisions for auto- booting under Kickstart 1.3; there aren't any sockets for boot ROMs on the board.
Pacific Peripherals has indicated, however, that it plans to make a daughtercard available at the time Kickstart 1.3 ROMs are released, that will add autobooting capabilities. The price of the upgrade has not been announced.
All of the manuals for setting up the Overdrive are on disk. The information in the files that comprise the manual is fairly complete, but the files themselves don't have any icons, which means that they can only be read from the CLI. The only printed documentation is a one-page summary card which reviews the software installation procedure. The information on this card, along with the auto-executing Startup-Sequence on the disk, should be sufficient for most users to install the software. Panitioning the drive, or installing the Fast File System, however, will require some work with a
text editor.
Unlike most products tested here, the OverDrive comes with an installation program that uses an Intuition interface.
The ODUtils program uses a series of pull-down menus to allow you to select and format various drives. The drive type selection is performed automatically, by issuing a SCSI command to the drive asking it to identify itself.
The program will also let you manually select the drive type. After you’ve selected the drive, another menu item lets you perform the low-level format procedure. When that’s completed, you may check the drive for bad blocks, and map out any that are found.
A final menu item has the program add Vi Bi&nwnae, Alle auslandische Computergeschafte Zeitschrifthandler Wilkommen in der erstaunlichen Welt von Amazing Computing™ - eine von Amerikas fiihrenden Zeitschriften fur Commodore Amiga Beniitzer.

The performance of die controller during the tests was generally good, though write speeds were somewhat slower than the other DMA controllers.
This was partially a result of the 2:1 interleave setting which was chosen in order to optimize read speeds. Other interleave settings might provide faster writes. Though the Overdrive was not quite as slow7 as the 2090A in the graphics and sound test, it did slow7 down the Sonix Play score that was playing in the background.
The OverDrive has enjoyed a position as the only krw-price DMA alternative to the Commodore 2090 for a number of months, Now7, however, it faces some serious competition from the Supra controller, which uses DMA transfers, has an autobooting capability built in, and is priced the same as the OverDrive. The only area in which the Overdrive appears to retain an edge is in its hard card design. At least until Microbotics comes out with its Hard Frame controller, die OverDrive remains the only controller board specifically designed for custom-building your own hard disk on a card.

(415) 651-1905 The C Ltd. SCSI Host Controller C Ltd. Was one of
the first companies to release a SCSI adapter for the
Amiga, and today it carries die widest line of SCSI Amiga
products. They sell complete hard drive systems for the
500, 1000, and 2000, ranging in capacity from 20 megabytes
to over 700 megabytes.
They have lots of experience with more exotic storage devices as well, including tape backup systems, 10 megabyte removable floppies, WORM drives, and CD ROMs. They've worked on a networking system based on their SCSI hardware. And soon, the company will expand into die desktop publishing market with Laser Xpress, a SCSI laser printer, and the Dest optical scanner, w7hich connects via a SCSI interface. In addition to its direct marketing effort, C Ltd. Also licenses its controller hardware and software to other drive manufacturers, including Pioneer and Phoenix.
The newest of the company's SCSI interfaces is its A2000 controller card, wrhich is the least expensive SCSI adapter available for the Amiga. Looking at it, it’s easy to see why. While a controller like the Conuncdore 2090A crams almost 50 chips onto a large circuit board, the processor-controlled (non-DAIA) C Ltd.
Interface uses exactly seven chips and a handful of discrete components. It's less than three inches high, and it's small size makes it a bit harder to plug in than the other boards, as well as less mechanically stable. The unit wre received for testing didr.’t even have a mounting bracket to attach it to the frame. In addition to the standard 50-pin internal and 25-pin external SCSI connectors, the board also has a connector for the front panel LED used to indicate drive activity.
There is no provision for boot ROMs, and C Ltd. Aas no plans to add autoboot- ing. They plan to take a ‘Avail and see" approach toward such an upgrade.
The Tshell makes using AmigaDOS fun. It makes the interface between you and the Amiga free of complications, intuitive and easy, while at the same time allowing complete control over the Amiga's operating system.
Although it is a professional tool having capabilities of an interpreted programming language, the Tshell is simple to learn and use Even if you're not a programmer, you can use the Tshell immediately as a high-powered CU replacement.

Amiga ond Tshell ore irooemafks of AT&T. Commoocre-AMIGAona Meiran Technology, respectively The rear part of the board has space wheie an Omti ST-506 to SCSI adapter can be mounted. Many of the
drive configurations C Ltd. Sells use such an adapter. Pioneer Computing uses the same space for a mounting bracket for a 3 1 2" hard drive, turning the controller into a hard drive card. As sold by C Ltd., however, the board is not really meant to be used as a hard card.
C Ltd. Sells most of its SCSI adapters as part of complete hard drive systems, and ships their hard drives preformatted, with a lot of useful public domain software already on the disk.
The installation software provided w7ith the SCSI controller, therefore, is not very sophisticated. It consists of an AmigaDOS batch file used to run the programs needed to orepare the drive for use. As of this writ ng, installation instructions were all or disk the latest version of a printed manual wras not ready.
For the test, I used a pre-release copy of the: Version 3 software. This software is designed to accommodate a wide range of SCSI devices other than hard drives, as well as networking over the SCSI port. It requires the user to create a te:ri file called Devsetup as well as the Mountlist file. Devsetup is used by a program called Devlnstall that is run before the hard drive is mounted.
Although C Ltd. Hasn't come up with much of a user interface to set up a drive using this software, all of the tools are there, including utilities to do low-level formatting and mapping out bad blocks on ST-506 drives (SCSI drives automatically map out bad blocks).
The company does plan, however, to write a mouse-driven installation program that will write the Devsetup and Mountlist file for the user. Aside from the Devlnstall program, drive installation and mounting follows the standard Amiga procedures. The MOUNT command is used to let DOS know the drive is there, and the FORMAT command is used to prepare it for storage.
Although the driver software was a pre-release version, the drive behaved quite reliably during the test period.
While it was among the slowest tested, there are a number of extenuating circumstances to consider. The C Ltd.
Interface seems particularly sensitive to the drive interleave settings. Different settings gave wildly different results on the Diskperf test.
At lower interleave settings, the reads were faster, but the writes slower.
The 32K buffer Diskperf test showed a maximum of 213 Kbytes per second on reads, and 48 Kbytes per second on writes. At higher interleave settings, reads peaked out at 128 Kbytes per second, while writes increased to 111 Kbytes per second. The 3:1 interleave setting we chose for our tests was a compromise value, but clearly, you can optimize your drive for either reads or writes using this interface. Optimizing for reads should yield somewhat better results than the benchmarks indicate. Another factor to consider is that C Ltd. Sells many of its systems with fast ST-506 drives and an Omti
ST-506 to SCSI adapter. This combination is reported to be significantly quicker than the standard SCSI configuration tested here.
The C Ltd. Controller has a lot going for it. It’s a time-tested design that's backed with a full one year warranty. It’s versatile enough to handle a wide variety of peripherals, from WORM drives to laser printers. But most of all, it's cheap. It's inexpensive design allows companies like Pioneer Computing to offer complete 30 megabyte hard drive systems for as low as $ 600. Though the speed of such systems might not be world-class, they're still quite respectable, and you can’t argue with the price.

(316) 267-3807 The SupraDrive A2000 Interface Supra Corporation
is another company whose hard drive products for the Amiga
have been around long enough to have been in our first
round of reviews. Supra has offered complete hard drive
systems for the 1000 and 500 for quite a while, but now
they’ve added an A2000 controller to their lineup.
Unlike previous SupraDrives, this new interface card does DMA data transfers.
The board contains three mounting holes which can be used to attach an ST-506 to SCSI adapter (Supra sells some versions of the board with this adapter already attached). Although these holes could be used to mount a 3 1 2" drive directly to the board in order to make a hard card, they weren't intended for this, and Supra doesn't encourage this practice.

The Supra installation software is also outstanding. The SupraFormat program is the only package tested to allow the user to control every aspect of the initialization process from a single, mouse and menu-driven screen. Like the Overdrive utilities, SupraFormat queries the SCSI controller in order to automatically identify the drive type. If the drive can be identified, the controller and disk type are displayed, as well as the SCSI device number, drive interleave, the number of surfaces (heads), blocks per track, and cylinders. If the drive can't be identified, all of these parameters can
be entered manually in the appropriate string gadgets. There are also spaces for entering landing zone, step rate, and write pre-compensation figures where needed (for non-SCSI drives).
Setting up drive partitions is a snap. You click on the partition name, type in the size in megabytes, and the program automatically calculates and displays the stalling and ending cylinders, and the amount of storage space that remains to be allocated. You may also select the old or new file system for a partition by clicking a gadget.
When you allocate all of the storage space, you can format the drive or just zero the partitions (a quick format), mapping out bad blocks if you so choose. When the format procedure is finished, the partition information is written to the drive, eliminating the need for updating the Mountlist file. Then all you do to boot the drive is use the SupraMount command the AmigaDOS formatting has already been done for you. Although the SupraFormat process is much simpler, Supra still allows you to use the AmigaDOS setup procedures if desired. Simply set all of the partitions to zero, zero them, and
use the AmigaDOS MOUNT and FORMAT commands.
The SupraDrive controller that was tested included a pre-release version of the autoboot ROMs. Running a special Convert program activates a special partition, BD0:, which takes up all of the cylinders below the low' cylinder of DH0: (future versions of SupraFormat will include lhe option to perform this function). This partition, which is automatically formatted with the old file system, becomes the boot drive. As with the 2090A, Supra’s pre-release autoboot ROMs didn't wait long enough for the 277 to come up to speed. Resetting once the drive warmed up allowed die system to boot from the
hard drive, however.

the only problems that were noted, and can be eliminated with a little fine tuning.
Of all of the controllers tested, the Supra interface stands out as an exceptional value. It costs only fifty dollars more than the lowest priced controller, but includes top-of-the-line features such as autobooting, DMA transfer speeds, and a SCSI cable and mounting kit. Its instructions are among the clearest, and its installation software the easiest to use.
Moreover, Supra is a solid company that’s been selling a wide variety of peripherals in the Apple, Atari, and Commodore markets for a number of years. In a volatile industry like personal computers, that's a pretty good indication that they must be doing something right.

• AC* by L. S. Lichtmann _AMAZING REVIEWS The Wshell Long ago I
became convinced that one of the things Commodore did right was
provide the parallel user interfaces of the Workbench and the
CLI. Icon- based interfaces are wonderful for casual use and
for novices, and command line interfaces remain unsurpassed for
power and flexibility. Unfortunately, the deficiencies of the
standard CLI environment and AmigaDOS are legion and too
notorious to elaborate here. These problems are slowly being
rectified by Commodore and by the vision of Amiga users and
One of the most popular shareware enhancements for the CLI interface is ConMan, by William S. Hawes.
ConMan adds command line editing and command history to the CLI. Anyone who has ever tried to get a listing for a directory four levels down can attest to the vaiue of these additions. Now Mr. Hawes is back with Wshell, a complete replacement for the CLI.
What the Wshell Is Not The computer term "shell” has two slightly different connotations. In its original use, a shell is a piece of system software responsible for mediating between the user and operating system, particularly in interpreting user input and loading and executing programs. However, especially in the MS-DOS world, shell has come to mean an applications program which simplifies the user's interaction with the computer. By presenting a graphic interface, a shell trades power for ease. Some shells (in this latter sense) and shell-like CLI enhancements are already available.
Wshell, however, is a shell in the older sense. It provides the full power of a command line user interface by substituting for the standard Cli and providing complete access to programs in the “C:” directory with many more options for command entry.
The Wshell Unlike Mr. Hawes’s previous program, Wshell is a standard commercial product rather than shareware.
Registered users of ConMan were offered an advance copy of Wshell's release version at a discount. (Those of you who may have been using ConMan without having sent the author a payment, your sins have come home to roost!)
Wshell runs on any Amiga, although it requires Version 1.2 of the system software. The program comes on a single half-full disk. The distribution disk has three major components: ConMan, the Wshell files proper, and ARP (each of which I will discuss). The distribution disk is not a boot disk, and a number of files must be copied to your system disk to use the Wshell. Mr. Hawes has thoughtfully provided batch files to perform the necessary copy operations. As you might expect from an author who lias produced shareware programs, there is no copy protection on the distribution disk or in any of
its programs.
Wshell’s documentation consists of a sixty-page typeset manual, spiral- bound so it lies fiat on a desk. The organization is excellent, and the descriptions and explanations are uniformly clear. Novices should be warned, though, that familiarity with AmigaDOS and the CLI is assumed. The manual includes a good index, and Wshell lists for $ 49-95- ConMan ConMan performs the same functions for Wshell that it does when used with the standard CLI, primarily giving Wshell line editing and command history capabilities. If you’re not familiar with ConMan, it consists of four files: "conhandler" and
’’conhandler.library” (which must live in the “L:" and ’’LIBS:” directories of your system disk respectively), and “conman" and "setcman" (normally placed in your “C:” directory) After ConMan and ail desired options (typically in your startup- sequence) are activated by the “conman" command, all CLI or Wshell windows subsequently activated are provided with ConMan's services. The "setcman” command allows modification of ConMan options once the program is running.
In addition to supporting basic editing functions such as backing up over the command line to ailow overwriting incorrect characters or inserting new ones ConMan supports a full set of special editing characters. For instance, the Shift-Left Arrow and Shift-Right Arrow combinations back up or advance one word in the line. The Control-Y combination deletes to the end of the line. The FI and F2 keys control window size: FI toggles the active window between its current size and an “iconi- fied" (minimum size) version: F2 toggles the active window between its current size and a full screen
Command history is accessible through the Up Arrow and Down Arrow keys. Previously entered commands are individually recalled from a buffer (most recent first) by successive pushes of the Up Arrow. Successive pushes of the Down Arrow move one command in the other direction through commands already recalled with Up Arrow, The new version of ConMan
(VI. 1) which is on the Wshell disk has added command history
search functions. Typing a line of text and pressing die
F5 key searches the history buffer for the last command that
has the entered text as its start. Searches in the other
direction (toward more recent commands) are performed with
F6 key.
Version 1.1 also has a utility command "history" that can be used to display the entire command history, save the command history to a file, or to load a new command history from disk. This feature allows you to pre-load sets of frequently-used commands.
Wshell Activation Wshell needs ConMan to function.
Along with the ConMan files, an additional file, “wshell.library,” must be moved to the "LIBS:" directory. The distribution disk contains an icon analogous to the CLI icon supplied on the Workbench disk to activate the Wshell. Wshell can also be activated from a command line using the “NewWSH" command which functions like AmigaDOS’s “NewCLI” command.
The NewWSH command, however, allows you to specify either an initial command for immediate execution by the new Wshell or a sequence of commands found in a specified disk file.
This arrangement forms the basis of my new startup-sequence file: con men -c . Octrvafe ConMan : Startup a wSnss wnn rne specifea console winaow ; and execute the commands h the file Boot-WShel NeWWX con: 30 frS0 1 ?Q Boor_w en c from j Boot-wSnea endci nit ; new close the sfcrtup CU The commands I formerly had in my startup-sequence file now reside in '‘Boot-WShell”."This way they are executed from a Wshell and have complete access to Wshell facilities. New Wshell-specific commands can be executed at boot-up time. A sample of this sort of "split startup” procedure is supplied on the Wshell
disk, The Wshell has an additional startup feature: if neither an initial command nor a specified file is supplied, the new Wshell looks in the "S:” directory for a file named “Startup-WShell.” If it exists, Wshell executes the commands in the file before issuing its first prompt.
Built-in & Resident Commands A standard complaint about AmigaDOS is that it is entirely disk- based. Unlike MS-DOS, AmigaDOS has no ‘‘intemal” commands. The case for having an "external”, disk-based system can be and has been argued persuasively. Nevertheless, I have frequently found myself wishing that a number of commands had been made intemal. The Wshell attempts to improve on AmigaDOS in this matter in two ways: "built-in” commands and “resident" commands.
Bu.lt-in commands are crucial to Wshell, but you can delete the corresponding command files in the “C:” directory 10 save disk space. The built-in commands are mostly batch file commands (such as “if' and “echo”) that perform elementary functions. Users are unlikely to replace these with their own versions. “Endcli” is also a built-in command, but you should retain the “endcli" command on disk for terminating any non-WShell command line interfaces you generate.

“CD" and “prompt” are also built- ins. Prompt is particularly interesting because it recognizes an extended set of special characters. As well as permitting insertion of “%N" (current task number) into a prompt string, the Wshell’s prompt command also allows insertion of the current directory, time-of-day, error return cooes, or any of about ten other special strings into the prompt. As well as a “standard” CD command, the Wshell has an “implicit” CD command you can type a recognizable path and director)' name without any command name, and the Wshell assumes you want to do a CD to this
director)' and perform the change.
Some built-in commands do not correspond to any AmigaDOS commands. For instance, the “pushed,” “poped," and “swaped" commands allow you to maintain a stack of frequently used directories, facilitating quick moves around a disk's directory structure.
Alternatively, you can define your own set of intemal commands with the “resi" (resdent) command. For instance, typing resi dir loads the ‘dir" command into memory from disk and adds its name to Wshell’s list of resident commands. Subsequent “dir” commands can be executed without reading the command from disk. Wshell keeps statistics on the use of the commands in the resident list.

(805) 582-0729 list of resident commands, reorder the list based
on frequency used to minimize search rimes, or remove
resident commands from the list. Wshell's resident commands
capability is preferable to storing commands in a RAM
disk because resident commands take less memory, less time
to execute, and do not require a special search path to
find commands on disk and in a RAM disk.
Resident commands are not restricted to tilings like “dir” and “assign.” Programs normally thought of as application software text editors, for instance can be made resident commands if they are written properly, Wshell searches the list of resident commands before searching the list of built-in commands. So if there is some command you must use instead of a Wshell built-in, you can do it. By- prefacing the command name with the left square bracket character CD, you can also force Wshell to bypass the search for resident and built-in commands and go straight to the usual search path.
ARP There is one restriction on using resident commands, and it sets me up for a digression on the third major element of Wshell. Resident commands must be “pure” code. The command must not modify its own code as it executes any “scratchpad” memory must be external to the command. (The other term used for such code is “re-entrant.”) Pure code is desirable for multi-tasking systems because it allows several Independent tasks to share one loaded copy of a program, making memory use efficient.
Unfortunately, most programs are not pure code; not even all the AmigaDOS “C:" directory7 commands are pure code. The Wshell distribution disk comes to the rescue in the latter case, however.
Wshell comes with the latest version of the ARP (AmigaDOS Replacement Project) commands, public domain replacements for Commodore’s “C:" directory AmigaDOS commands.
The ARP commands are faster than their AmigaDOS counterparts, much smaller (freeing a great deal of space on your Workbench disks), and have a more consistent set of command line parameters. Many have extra capabilities not found in the corresponding AmigaDOS commands, and a few new commands not present in AmigaDOS at all are included. Equally important for the Wshell, all the ARP commands are pure code. (In fact, ARP has a “resident” command which serves the same function as Wshell’s “resi,” although I prefer “resi” because it has more capabilities.)
Aliases Wshell also provides “aliases” as another way of customizing the Amiga's command set. Aliases define multiple names or abbreviations for commands. If you are more comfortable with a certain trademarked operating system directory command (“Is”, for instance), but still want to give the Amiga’s “dir" command, give the Wshell the command alias ls=dir Thereafter, typing “Is” executes “dir.” The “dir” command file is not renamed, so it is still accessible by entering “dir,” The “alias” command also supports multi-word replacement.
Entering alias print='type prt:' activates the command “print file!” and sends the contents of filel to tile printer.
Alias can also cause Wshell to recognize particular strings as abbreviations for standard commands. The case of the characters in the alias string specify characters that must always be typed for the command. Thus alias Mkdir=makedir causes “ink," “mkd,” “mkdt," and “mkdir" to be recognized as “makedir." Other options allow7 you to list aliases currently in effect, or to delete particular aliases.
Pipes Pipes chain together commands so the output of one command serves as the input to the next without speed and space penalties associated with setting up an intermediate file. You can set up pipes by inserting the character “ I ’’ between commands you want to chain.
For example, a program called “Tee” takes any input given to it and copies that input to both the screen 2nd the "standard output” (which is also die screen unless otherwise specified). The command line then dir l Tee dirfiie 35mm SLIDES FROM VOUR ARTWORK!

el causes a directory listing to be sent to the program “Tee.”
The redirection causes the output to be temporarily redefined
as a disk file named “dirflle.” Thus, this command line
produces a directory- listing on the screen which is also
saved to a file a function long on my wish list!
To use pipes, you must mount a “pipe handler.” The mounting operation may be unfamiliar to many users. You must have a file named “moundist” in the “DEVS:" directory of your system disk containing information needed by the operating system. An appropriate "moundist” file for the pipe handler is provided on the Wshell disk. You must also issue the command Even Up The Score!

Mount PIP: before you can use pipes (usually in your startup-sequence). The Wshell manual includes clear instructions for this procedure, although it would have been nice if the Wshell installation batch file had set up an appropriate moundist file.
The Wshell Environment Wshell provides itself one form of “environment variables, "global values that set certain modes of behavior. To set up the Wshell environment, you create a special directory (on a permanently mounted device, such as the RAM disk) and assign the device ENV: to this directory. The environment variables are the files in this directory', and the values of the variables are the text contents of the files. For example, die Wshell looks for an environment variable named “titlebar.” If you have a file in the “ENV:” directory named “titlebar,” and it contains a valid Wshell
prompt string (die arguments of a Wshell “prompt” command), Wshell writes the specified prompt string into the title bar of the Wshell’s window. Thus, if the contents of the file “titlebar” are %C Wshell writes the current directory' into die tidebar and updates the bar everj- time a “cd” is executed.
In addition to “titlebar," the current version of Wshell uses other environment variables. “Path” sets a global search used by all Wshell windows as a “last resort” when hunting a command.
"Echo" controls display of alias translations. “Shellwindow" controls the default size, etc., of new Wshell windows.
The .LRexx Connection One of Mr. Hawes avowed purposes in developing the Wshell was to integrate his Arexx language (available as a separate product) into a command-line environment. Arexx is an Amiga implementation of the REXX language that originated on IBM mainframes. Arexx really deserves a review of its own, but I can summarize by saying diat it is an interpreted language (like BASIC) that runs on a memory- resident interpreter loaded at boot time.
The language's features make it useful as a powerful alternative to the usual Amiga DOS EXECUTE batch files, and as a medium for writing additional high-level commands. The “Tee” program mentioned above is an .ARexx demonstration program included on the Wshell disk.
Arexx also defines a standard interface that makes it possible for application programs to easily add macro facilities and for different application programs to talk to one another. (Some commercial programs, such as Microsmith's TxEd Plus, already have .ARexx interfaces.)
Wshell provides transparent support for Arexx. To run an Arexx program once the interpreter is mnning, simply type the name of the program. No special command, such as the AmigaDOS “EXECUTE," is necessary. Wshell also recognizes in-line .-ARexx programs if the appropriate Arexx statements are entered between double quotes.
Final Item arks Taste in software is a notorious idiosynciasy (particularly' in user interfaces), and recommendations should be filtered through your own likes and dislikes. I really like Wshell. I tried to think of criticisms, ways in which I fell it was deficient, and came up blank. The software performs very useful functions and -works as advertised. Tire documentation is excellent, and the package is an outstanding value even at full list price.
All in all, 1 think the Wshell is a shining example of what commercial software should and can be. I can’t imagine how I got along before I had it.

At press time, they remain unconfirmed and are printed for entertainment value only. Accordingly, the staff and associates of Amazing Computing cantwi be held responsible for the reports made in this column.] by the Bandito Hardware news: While the RAM shortage is far from over, things are getting better. Prices are dropping, though they are still far above what they used to be. Availability is also improving.
Once some of the new chip factories “RAMp” up, perhaps RAM costs will drop the way they did in the good old days.
The RAM shortage has already had an impact on the hardware market, though, with some product prices increasing and others kept front the market entirely. For instance, Progressive’s FraineGrabber went up from $ 499 to $ 599 because of the high cost of RAM chips. As die Bandito speculated, NewTek's Video Toaster will be delayed because of the RAM shortage. Now they’re saying Christmas, but they promise the product will be better for the delay. Let's hope they can stick to their original price the way RAM chips have gone up, that would Ire some trick. The Bandito expects a higher price tag and
a later ship date.
In tlr is fast-paced industry, it seems that companies are always changing the roster. This time it’s Progressive Peripherals, who have ended their cross-marketing relationship with Precision Software from Tngland. Two employees left Progressive to join Precision, which will now market its products directly in tire U.S. Also at Progressive, Dan Browning and Eric Stein departed, and Pixmate programmer Justin McCormick is now in charge of marketing. (The Bandito thinks more programmers should be involved with marketing. Too many marketing beings barely know how to turn on a computer.)
Microlllusions has lost one of its hot programmers. Reichart, author of FirePower and other titles, is forming his own development group. He claims to have an unbelievably large number of programmers working with him. Currently in development is a BBS-based role playing game for the Amiga with some hot graphics. Reichart has also designed an Amiga animation program to help professional animators.
More Micro-I news: Jim Steinert, head of Microlllusions, is trying to sell KJ Computers, the store where he started the company. It seems that trying to run a retail store and produce software at the same time is just too much of a hassle.
Our friend Ami is starting to get bigger movie roles AlOOO's appeared in Disney’s recent Sunday Movie Not Quite Human. Some Amiga graphics svere even shown. Wire-frame animation was shown; ray-traced Amiga graphics would have looked too good to be convincing! Both the good guys and the bad guys had Amigas, which just shows that Amigas are not inherently good or evil.
(Remember, Amigas don’t kill people people kill people) If graphics are outlawed, only outlaws will use graphics.
What does Commodore have against Ami-Expo? Well, Deep C (the Bandito’s Commodore connection) states that Commodore was upset when Ami- Expo tried to get the right to put on the Amiga Developer’s Conference. Of course, that may not have anything to do with the fact that Commodore is trying to get developer support for the World of Commcxlore show, instead of for Ami- Expo. Developers will probably support both, but with less enthusiasm for World of Commodore since it’s not Amiga- specific, Who wants to hang around with a bunch of C64’s, anyway? The future is Amiga. This is the last Christmas
for the C64...but then again the Bandito has heard that line for the last three years.
In other Ami-Expo news, the LA Amiga Users considered boycotting Ami- Expo because of its high price. At press time, Ami-Expo had not yet happened, so the Bandito doesn't know if they’ll go through with tire ihreat. It costs 525 to get in, plus $ 15 for hotel parking, which adds up to a pretty penny. That’s the price of a good piece of software hfflmm, maybe they should give a program away at the door. Any corporate volunteers out there?
Game news: Starglider II is shipping, and it has the fastest frame rate of any real-time 3D game.(The Bandito knows there’s a whole audience out there who just cares about frame rate to heck with the game!) Rocket Ranger is shipping, and sales are red-hot. Players say that Cinemaware has more game in there along with the graphics and sound.
News you won't hear anywhere else: Though Apple and Commodore are deadly rivals in the marketplace, that doesn’t prevent them from doing business together. The Bandito has learned that the Apple IlGS's 15-voice music chip is made by none other than MOS Technologies which is owned by Commodore. Makes you wonder if the next Amiga might not have a few more voices on the sound chip, eh?
Commodore expects to sell 300,000 Amigas this Christmas. Developers are crossing their fingers and clutching their prayer beads.

flying off the shelves like they thought it would.
With no advertising, what do they expect? Dpaint III should be coming soon perhaps by Christmas though it won’t add HAM capabilities. It does have some animation tools, and every Dpaint owner will want to upgrade.
What happened to Digi-Paint II and Photon Paint II? Both were supposed to be out in the spring, and it’s beginning to look like fall around here.
Whispers are that both are adding features and squashing insects. The Bandito thinks both will try hard for a Christmas ship date whether or not they’ll make it is debatable.
Just to set the record straight for the less informed gossip columnists, Steve Jobs already owns Pixar. By the way, Pixar & developing rendering software and a “Pixar-on-a-card” for the Mac II. That would be a nice Amiga product, but don’t hold your breath.
More Steve Jobs news: The NeXT computer will finally appear October 12.
It’s taking some pages from Amiga’s book great stereo sound, a graphics coprocessor for fast animation, zillions of colors, and high resolution. However, it’s going to be very expensive RAM prices have hit here, too. The operating system is a UNIX variant, and they've licensed Display Postscript from Adobe for the screen.
The NeXT computer is supposedly just for the higher education market, but don't believe it. Jobs wants the whole enchilada he’s after the Macintosh and the PS 2 market share, as well as the Sun workstation market. This guy thinks big.
In fact, he’s just inked an agreement with his old arch-rival IBM, giving IBM the right to use NeXT's display technology (interface). This deal gives Jobs more money and a great deal of prestige in the business world.
Interestingly, Apple has reviewed the NeXT computer and signed off on it, saying that it does not infringe on any proprietary Apple technology (as per Jobs’ agreement that he signed when he left Apple).
Atari is suing the former owners of the Federated Group, claiming that Federated misrepresented the company’s value when they sold to Atari. Since Atari is still losing gobs of money at Federated, this is one way to tiy to make up for that. At the same time, Atari has let it slip that they wouldn't mind selling Federated, but no interested buyers have yet appeared. In other news. Atari raided a number of New York dealers and seized $ 100,000 worth of counterfeit Atari 2600 machines and cartridges. Gee, wonder why the Taiwanese pirates haven't bothered to counterfeit Atari ST's?
What is Epyx really doing? The I- VCR thing the Bandito described previously was apparently misinformation from an Epyx apparatchik. Now the Bandito hears that it may be a 16-bit videogame. After all, Amiga originally made a joystick, just like Epyx does now, and then produced a computer you may be familiar with.
There are also quite a few Amiga alumni at Epyx these days. They can’t be daring enough to take on the expensive fight-to-the-death videogame market, can they? They sure are. Darker rumors hint that the machine is based on a 68000, and that they’ve licensed Lhe Amiga chip set for graphics and sound. (Many people are interested in getting rights to the Amiga’s technology, from what the Bandito hears.) They're obviously trying to capitalize on the availability of 68000 programs and programmers to rapidly create a large base of available software.
What we may have here is an Amiga truly configured as the ultimate home videogame with a target price around $ 250. The A500 may already have that market, though, even with its higher price. It seems to the Bandito that other publishers might be wary of producing software for a machine owned by a competitor. That would give Epyx the money they need to improve its position in the software market.
Ep w’s machine isn't the only 16- bit videogame threatening to appear.
Nintendo .s developing its 16-bit game machine. They released it in Japan and plan to br ng it over here next year. Also, NEC has its PC Engine on the way that uses an oddball 16-bit processor and some cool 256 color graphics as a high- end game machine. They plan to offer it for about $ 200 with an optional CD-ROM drive for another $ 300 to $ 400.
Adding a CD-ROM player begins to make the PC Engine sound like a CD-I player, though at a lower price. And what is happening with Compact Disc - Interactive? As the Bandito reported earlier, it :.s running “way late." Now they’re talking Xmas 1989 for the introduction of the first players. Prototype players should arrive at developers in a few weeks.
Developers are still spending incredible amounts of effort to develop for CD-I. One major publisher has already spent over a million dollars on CD-I development, Why so much interest in CD-I, even though it's so late to market? Well, publishers and developers talk about the TV quality graphics and CD quality sound, the animation, the amount cf storage, and the real mass- market potential. But a lot of sexy technologies before have failed to attract to much attention. (The Amiga still doesn't get the respect it deserves from software developers.)
The Bandito thinks the reason for all the de veloper enthusiasm is metre fundamental than graphics, sound, storage, or mass market. The basic fact is that CD-I products can't be copied. Publishers and developers both salivate at the drought of eliminating piracy. Of course, somebody will get around this limitation (and DAT or THOR-CD might be just the ticket), but until then, it's profit city. After all, publishers are convinced that for every legitimate copy someone actually pays for, anywhere from rwo to ten freebies are out there. If they could get all that lost revenue, they’d be rich
(or so they think).
Speaking of Tandy's read write optical disc, Tandy is staffing up with engineers to tty and make THOR-CD a reality. It’s likely that they won’t have a commercial product for another two years or more, but they may mess up the marketplace until then as everyone waits for it. It’s the old Jack Tramiel strategy announce some vaporware and see how many orders you get, while the competition runs around chasing its tail trying to figure out if you really mean it.
One way to remedy CD-I’s lack of writeable storage is to add an A D converter and a little circuitry (about $ 6 in parts) so die CD-I players can record on your VCR. That would make plenty of storage, and it would enable some more common program types to use CD-I.
(What good is a paint program unless you can save images)? Of course, DAT or THOR-CD could make this a moot point.
Great news for Commodore: Apple has just raised prices on most of its computers. The Mac II went up nearly 30%! And the IIGS went up nearly 10%, while extra memory for it went up 77%.
This makes the distinction between the Mac II and the A2000 sharper than ever.
Why did they do it? Well, Apple’s DRAM contract expired. To meet demand, they must buy chips on the spot market, which eats into their (aptly named) gross profit margins. So they raised prices, figuring customers would flinch, but buy the stuff anyway. This means prices will stay up if demand does. Apple is happy to make the extra profit.
This also means the IIGS Plus will be more expensive. The Bandito hears that the IIGS Plus release is being delayed, partly because of the price increase. Apple will probably keep the decision up in the air until the last minute, but look for them to ship either in time for the late spring or late fall education market buying times.
Apple just introduced the lie Plus, which has a 3.5 inch drive and a faster processor. List price is SI099 for a one- drive, color system. (It’s amazing how fast those horse-drawn carriages can go, isn’t it?) Apple also introduced the Mac Iix, with a 68030 instead of a 68020. For some reason, the press reports the speed is only about 15% faster must be a slow 68030 chip.
The important news is the new
1. 4 megabyte disk drive that can automatically read IBM 3.5
inch disks and provide software to help with some file
conversions. Why can’t Amiga do this?
It’s the only kind of compatibility most people need. Get some conversion software and build that drive into the next A2000. EA’s DeluxePaint on the PC uses IFF files, so graphics shouldn’t be a problem. Why fool around with bridgeboards...and the extra expense?
Most people just want to read in word processing or spreadsheet files, anyway.
While we're on the subject of Other People’s Computers, IBM’s PS 2 line is under fire. While IBM claims great success for the PS 2’s, most of the PS 2 computers they sell still have the old bus architecture. (Their MicroChannel has not been exciting) Most buyers look at it and think,”Gee, I can’t use any of those expensive cards I bought for my old PC, and this new Micro Channel doesn't have any cards." So all tire oilier MS-DOS clone makers have created a new bus standard that will use all the old cards, as well as new cards that offer faster performance. It will be interesting to see which
side wins in the "bus battle.” And we thought we had problems switching to the Zorro standard.
But that’s not the only IBM news.
As you may recall, they tried to get into the home and education markets with the ill-fated Pcjr (with the infamous chicklet keys). They were laughed out of the market, nursing their wounds. They tried again with the PS 2 Model 25, but that got nowhere in home or education.
Lack of sound was a major reason.
Well, IBM doesn't give up easily.
Some developers have already been shown a new IBM model (or parts of it IBM is very tricky when it comes to new stuff). The minors whisper several things, but the version the Bandito likes is an 80286-based machine with VGA graphics and an ADPCM sound chip that has CD quality digitized sound, a blitter chip for fast animation. All for about $ 1500. Sounds like they want to knock off an Amiga, doesn’t it? Look for something like this at Spring Comdex, and tell’em tire Bandito told you.

K E Y C L I C Program a typewriter click into your Amiga keys.
K by Mike M. Duppong Delphi: MOCKO Genie: MMD One thing I always missed on the Amiga was an audio click when keys were pressed. While the Amiga keyboard has the best feel of any I've typed on, it doesn’t have tire audio feedback that aids touch-typing. Thanks to the multitasking operating system, adding this feature is relatively painless for both user and programmer.

Each time you press a key or a mouse button, an audio click sounds. Simply close the -window to end the program. That’s
about all users have to know.
For you programmers out there, the center of activity revolves around a custom input handler. The handler simply signals the waiting task when a key or mouse button event arrives in the input stream. Once the task is awakened, it sends a command to the audio device to initiate the click and goes back to sleep. Therefore, this program only uses a significant amount of processor time when a key or mouse button is actually pressed.

This sometimes made the program sluggish, so, for better response, I let the program set its own priority to fort)'. You can change priority by assigning a different value to TASKJPRIOBITY, defined at the beginning of tire program.
In a busy system, I managed to confuse the audio device on several occasions by pressing keys as fast as I could. I could use some feedback on how' to prevent this, but it shouldn't be a problem when you’re typing normally it takes some real keyboard-bashing to cause the error. The problem seems to be that the audio device clams up and won't talk to tire program.
Air error message pops up on the screen's title bar when the Keyclick window' is selected. To get around the problem, just close tire current Keyclick window and nin the program again.

Techniques and Applications by Forest W. Arnold In AC V3.7,
William Gammill detailed linked lists and their usefulness for
managing dynamic memory. This article presents two clever
macros for dealing with doubly-linked lists.
In this article, I discuss singly-linked lists and list algorithms, develop procedures for managing the lists, show how different data types can be stored in the same list, and finally, present a simple graphics program to demonstrate how lists can be used.
Why Use Lists?
The first time I used a programming language with facilities for building linked lists, I couldn’t see how anything which looked so complicated could be worth the effort. At the simplest level a list storing only one kind of data the only advantage I could see for using lists (instead of arrays or matrices) was that I didn’t need to know in advance how much memory tire data needed. This dynamic aspect of lists is clearly an advantage over matrices, but I still didn't realize how powerful linked lists were. That is, until I learned how to store different data in the same list and how to build
tree structures.
When combined with C structures, function pointers, and recursion, linked lists can implement very complex program and data structures with surprisingly simple and concise techniques.
One example is the Amiga operating system and the Intuition software built on top of the system software. All Amiga and Intuition structures, tasks, files, and devices are created, managed, and destroyed using lists and queues. Lists and queues are implemented and manipulated with a only a few procedures. Much of the Amiga’s power, flexibility, and elegance can be attributed to the dynamic nature and generality of lists and queues.
Another example of the power of linked lists is provided by LISP, which combines both code and data into lists, lists of lists, lists of lists of lists, ad nauseam. It accomplishes this magic through these list structures and a single recursive “eval” routine (which “evaluates” the lists).
At first glance, structures and programs built from lists and trees appear complex, but the techniques and algorithms to construct and manage complex trees of program structures and data structures are the same as those used for a single linked list. Once you understand how to work with one linked list, you understand them all, no matter how elaborate. The following section describes two variations of the simplest type of list the singly-linked list. Doubly-linked lists are also briefly described.
Basic Linked List Structure If you have read some popular C programming books or the linked Lists article in AC V3.7, you probably already have some idea what a linked list is. If you are just starting with fists, though, this section should help you better understand the basic structure of finked lists.
A linked list is a sequence of objects (nodes) connected by pointers. Each list has a start node (the list head or top) and an end node (the list tail). Each node in the list has the same structure, and contains a link which specifies how to access (at a minimum) the next element in the list. A simple node for a singly-linked list can be defined in C as follows: typedef struct node struct node ‘next; * pointer to next node 7 unsigned chor ‘data; * pointer to the data 7 ) NODE_T; The pointer to the next node in the list (“next”) is called the link, since it strings the nodes together. Using
type “unsigned char •” to point to the node’s data lets you see the node structure as a “hook.” The "hook” points to any type of data structure you need and maintains a consistent set of procedures for manipulating the list structure, no matter how complex things get.
When the data pointer is placed in the node, the type is cast to “unsigned char when the data is accessed, the type is re-cast to the correct type. The cast operator ensures that the compiler correctly generates offsets into the poinred-to structure, and prevents die compiler from generating a lot of messy warning messages.
A doubly-linked list can be created by adding another pointer to the above structure. The doubly-linked list node is defined as follows: typedef struct node 1 struct node 'prev; ' pointer to previous node * struct node 'next; * pointer to next node 7 unsigned char 'data; * pointer to node's data 7 ) DNODEJ; A singly-linked list can only be traversed from a given stan node in the list to the end node. The start node can be any node in the list that can be accessed. A doulily-linked list can be (continued) If different types of data are stored in the same list, the 'dType’ field is stored in
the node structure instead of in the list header (since each node can carry around different data). The demonstration program in Listing 1 uses this technique to store both “point" structures and “line" structures in one singly-linked list. Another variation of the node structure for storing different data in the same list uses C's union construct to hold the actual data or a pointer to the data (rather than an untyped pointer to the data). The disadvantage of stormg the data using a union is that space is wasted if the data types are different lengths.
Figure 1 depicts a singly-linked list and a doubly-linked list. When drawing linked lists, the nodes are usually shown as rectangular boxes and the links (pointers) are shown as arrows pointing to the “next" (and “previous”) node. An “X” in a “next" box indicates the NULL pointer.
Singly-linked lists are either first-in, first-out (FIFO) lists, or last-in, first-out root [ J traversed from any node in the list either back to the beginning or forward to the end. Exec's lists are doubly-linked lists, while Intuition’s menu structures are singly-linked lists.
Memory For both the list nodes and the pointed-to data structures is usually dynAMIGAlly allocated as needed, and freed when no longer needed. This way the data structures can grow as large as memory permits, while using only the memory actually required. Dynamic memory allocation and deallocation are major benefits of linked lists. Statically allocated structures, such as arrays, always seem bigger than anyone ever needs.
(Except the first real user.)
To "anchor" the list to a place in memory where it can be easily accessed, a Figure One Singly-Linked List HEADER COUNT I D HI HI Doubly-Linked List HEADER COUNT IXT NEXT MODE | PSP | nexT I' first node in the list 7 • last node in the list 7 ' data type for the nodes 7 * number of nodes 7 Stack with 6 entries R NODE 1 NEXT NODE 2 NEXT NODE 3 NEXT NODE 4 NEXT NODES | NEXT | f H l~ 1 list header structure is generally used (but not strictly necessary). The header is another C structure which contains at least a pointer to the first node in the list. It may also contain a pointer to the
last node in the list, particularly if the list is doubly-linked or implements a queue. Other information frequently stored in the header includes a tally of nodes, a name for the list, and information identifying the type of data the nodes point to if all data in the list are the same type. A typical list header could be defined in C as follows: The list header structure Exec uses is almost identical to this example.

Stacks (UFO) lists. In FIFO lists! Nodes are always removed
from the "top" of the list, and the First node placed in the
list is the first node removed from the list.
In LIFO lists, the last node placed in the list is the first node removed. When queues and stacks are implemented as lists, FIFO lists are used for queues and LIFO lists are used for stacks because of the insertion-removal relationship. Figure 2 shows list representations of both queues and stacks; the demonstration program creates both types of lists and prints them to files.
The basic data structures for all linked lists have now been presented, and all that is left to describe are the actual operations needed to manage lists.
List Operations A nice thing about linked lists is that there are only a few basic operations for lists; there are many variations in implementation, but the fundamental algorithms are the same. The basic operations are: (1) create a list; (2) create a node and its data; (3) insert a node in the list; (4) search a list for a node; (5) remove a node from the list; (6) delete a node and its data; and
(7) delete a list.
Once mastered, these operations can be applied to any linked list. In fact, if data type dependencies are kept out of the implementation, the exact same code can be used for any list.
(This was the purpose of the macros described in AC V3.7). This portability suggests packaging the node structure definitions and list operations into a single file as an abstract data type, usable without modification by any application. The code in the demonstration program does contain data dependencies. In my next article, I'll discuss how function pointers can be used to eliminate type dependencies.
In the following paragraphs, the basic operations for singly-linked lists are described as sequences of steps. Each description is followed by a description of the actual procedure in the demonstration program that implements the operation. The operations are meant for lists that can store pointers to different data types in each node. Aside from removing nodes from a list, all the operations are very simple and can be implemented with only a few lines of code.
List creation:
1. Allocate space for the list header.
2. Set the list “top" and “tail" pointers to NULL; set the
optional “count" field to zero.
In the demo program, the list headers are declared as actual structure instances (instead of being dynAMIGAlly allocated) because only two are used. The header structure is “typedefed” as HEADER_T. The header is an “empty" list into which nodes can be inserted.
Node-data creation:
1. Allocate space for the node.
2. Allocate space for the pointed-to data.
3. Initialize the variables defining the data to the appropriate
4. Set the node data-type field to the code that corresponds to
the data structure.
5. Set the node “data” pointer to the address of the initialized
data structure, type-cast as ‘unsigned char *’
6. Set the node “next" field to NULL.
The demo program uses two data types: a POINT_TYPE and a LINE_TYPE. These correspond to the POINT_T data structure and the IINE_T data structure and are -define’d as integer values. The procedures createPointO and createLineO are implementations of node-data creation and initialization.
Both procedures return pointers to the newly-created and initialized NODE_T data structure.
Next, the node must be inserted into the node list. The method used depends on whether the list is a FIFO list or a LIFO list. For FIFO lists, new nodes are always added to the end of the list. For LIFO lists, new nodes are always added to the beginning of the list.
LIFO list node insertion:
1. Set the new node's “next” pointer equal to the “top" pointer
in the list header.
2. Set the "top" pointer in the list header equal to the address
of the newly-added node.
3. If the node is the first added to the list, set the “tail”
pointer in the list header equal to the address of the new
4. (Optional) Increment the list node counter variable.
FIFO list node insertion:
1. If the new node is the first node added to the list:
a. Set the “top" pointer in the list header equal to the address
of the new node.
B. Set the “last” pointer in the list header equal to the address
of the new node.
2. Otherwise, set the “next” pointer of the last node in the list
equal to the address of the new node.
3. Set the “tail” pointer in the list header equal to the new
node’s address .
4. (Optional) Increment the list node counter variable.
The procedures insertlnStackO and insertlnQueueO in the demo program are implementations of list node insertion.
Both procedures take a list header's address and the address of Figure Three UFO 11 BEFORE node 4 inserted | htASCP j 3 | flgtiJ [ Ug«1 |

insertion a node to add to the list as input arguments and then
add the node to the list. Figure 3 shows "before" and “after”
pictures of list node insertion.
To search a list for a node:
1. Set the current node equal to the “top” node in the list
2. If the current node is NULL, the end of the list has been
found. Return NULL.
3- Otherwise, compare the node or the node's data to the search criteria.
4. If a match is found, return the pointer to the node.
5. Otherwise, set the current node equal to the address of the
node stored in the current node's “next” pointer.
6. Go to step 2.
Searching a singly-linked list follows the chain of link (“next”) pointers. The process is often called “pointer chasing."
The actual search criteria used depends upon the application. In the demo program, the search criteria are (x,y) coordinates generated by a mouse select button event. SearchLiscO implements the coordinate search and returns either a pointer to the found node or a NULL pointer.

To preserve the list’s integrity when a node is removed, the “next" pointer that precedes the “to-be-removed” node must be set to point to the node after the node to be removed. If the node
being removed is the first node in the list it obviously has no predecessor, and if it is the last node in the list, it has no successor. This quirk makes implementation of the algorithm more involved.
7b remove a node from a singly-linked list:
1. If the node to be removed from the list is the top node in the
a. Set the “top" pointer in the list header equal to the "next”
pointer of the node to be removed.
B. If the node to be removed is also the last node in the list,
set die “tail" pointer in the list header to “NULL."
C. (Optional) Decrement the list node counter.
TL Return “success.”
2. Otherwise, set the previous node equal to top node.
3. Set the current node equal to the previous node’s “next”
4. If the current node is “NULL," return “failure."
5- If the node is equal to the node to be removed:
a. Set the previous node’s “next" pointer equal to the current
node’s “next" pointer.
B. If the current node is also the last node in the list, set the
“tail” pointer in the list header to point to the previous
C. (Optional) Decrement the list node counter.
D. Return "success."
6. Otherwise, set the previous node equal to the current node. Go
to step 3.
If the list is a LIFO list, the “tail" pointer in the list header is not needed, and node removal can be simplified by eliminating the steps that check for removal of the last node. The procedure removeNodeO in the demo program implements the algorithm shown above. Figure 4 is a diagram of a list before and after removal of a node.
To delete a node-data couple:
1. If the node pointer is NULL, return “failure.”
2. Otherwise, if the node data pointer is not NULL, free() the
“pointed-to" data structure.
3. Free( ) tire node structure. Return “success.” The demo
procedure deleteNode() takes a node pointer as input,
determines the type of the pointed-to data, and calls
deletePointO or deleteLineO to perform the actual node-data
The final singly-linked list operation is deletion of the entire linked list. This is done by iterating through the list, and deleting each node-data couple when encountered.
To delete an entire singly-linked list:
1. Set the current node equal to the list “top" node.
2. If the current node is NU1X:
a. set the “last” node pointer in the list header to NULL.
B. return “success."
3. Otherwise, set the list “top" node pointer equal to the
current node's “next” pointer.
4. Delete the current node.
5. (Optional) Decrement the list node counter.
6. Go to step 1.
We’ve now seen all the basic list operations. Before we move on to another topic, I’ll make a few comments. First, unless adding the node-data couples to the end of a list is necessary (for a queue, for example), the tail pointer to the last node in the list is unnecessary. Second, in many cases, the list header itself can be eliminated. Umess information that applies to the list as a whole is needed, the list can be accessed by a statically-allocated node as the first node in die list.
Finally, in cases that require many small memory allocations and deallocations, using "malloc” (or “calloc”) and "free" can be time-consuming. If speed is a primary consideration, implement an internal memory management scheme, allocate a large chunk of memory at start-up time, and use custom w'ritten procedures to allocate and deallocate small segments of memory.
Disadvantages of Using Lists Aside from memory allocation speed, the only drawback I find with linked lists is that to access any given node, the list must be searched sequentially. This is true for both doubly- and singly-linked lists. Even when data is inserted to the list in sorted order, the list must still be sequentially searched. Several techniques (beyond the scope of this article) can overcome the search drawback. Such techniques allow' a node to be found in the time it takes to perform a binaiy search of an array.
Putting Lists to Work Seeing uses for linked lists :s much more informative than reading a description of how they work. So, in addition to the procedures that implement the basic list operations, the demonstration program also contains the following procedures to manipulate lists:
1. Procedure reportListO prints the node structure and the
pointed-to data structure to a file.
2. Procedure displayListO graphically displays the pointed-to
data (points t.nd lines) in an Intuition window.
3- Procedure displayNodelnfoO highlights a picked point or line and displays the point or line data in a text message window. This procedure calls display PointlnfoO or dispIayLirelnfoO to highlight and display the data.
LISTDEMO.C The Demonstration Program The demo program in Listing 1 is contained in a single file and can be compiled and linked in one step. The Lattice compile and link command is Tc -L listDemo.c'. The program is run from a CL1 wandow.
The program creates both a FIFO list and a LIFO list, each containing five point data rypes and five line data types.
The program prints each list to a separate files in the current directory, so you can see the difference between the lists. The FIFO list output file is “queue.out,” and the LIFO list output file is “stack.out”. The FIFO list is then deleted since it is not used for tire remainder of the program. The program also deletes the first and last entries in the LIFO list, and again prints the list after each node-data couple is deleted.
Then the program gets a little more interesting. Intuition is set up, a window is opened, and the LIFO list data is graphically displayed. The program calls handlelnputf ), an input handling procedure that monitors the IDCMP until the mouse select button is pressed and released. The mouse cursor coordinates are sent to the procedure searchListO, which looks for a node at the selected coordinates.
If the selected coordinates are within four pixels of a point (displayed as an “x”) or line segment, searchList() returns a pointer to the node that points to the point or line. The input handler then halts monitoring the IDCMP and calls displayNodelnfoC) with a pointer to the found node. The point or line is “highlighted,” and gpDisplayMsg() displays the data for both the node and the picked point or line in a “message” window. Closing the message window with the close gadget returns control to handlelnputO, which then resumes monitoring input events. Closing the graphical display window
with the close gadget stops the program.
I mentioned earlier that some list procedures contain data type dependencies. These procedures are reportListC ), search- ListC), displayList( ), displayNodelnfoC ), and deleteNode().
Each procedure makes specific comparisons of the dataType variable stored in the node to determine if the “pointed-to" data defines a point or a line. The procedure then calls the appropriate point or line procedure.
Embedding type dependencies in a procedure guarantees that the procedure can be used only for the specific types coded into the procedure. In my next article, I'll discuss a technique that uses function pointers and function pointer tables to remove type dependencies from the code. I'll use this same demonstration program (with modifications) to demonstrate the function pointers.
Conclusion Lists containing only primitive node-data couples are handy and provide a consistent mechanism for manipulating varied types of data. The real power of lists, though, is not evident until they are used in tree structures. Since a node in a list can point to anything (including procedures), the node can also point to another list. By constructing lists whose elements are also lists, very complex, hierarchical data structures can be easily implemented and managed with only the simple methods discussed above. In fact, if properly constructed and combined with die proper control
mechanisms, an entire database can be managed by simply managing the single record that contains the top-level header or node.
Once you understand pointers and master the algorithms presented in this article, you should be able to begin exploiting the full power of linked lists in C. Further Reading Two of the best, most understandable books covering linked lists I have found are: Advanced C: Techniques & Applications, Gerald E. Sobelman and David E. Krekelberg, Que Corporation.
Data Structures and Cprograms, Christopher J. Van Wyk, Addison-Wesley.
Advanced C: Techniques & Applications, is available in paperback and is relatively inexpensive. If you are interested in applying lists to graphics programs, I highly recommend it. Data Structures and C Programs is more theoretical and covers a wide range of advanced topics (applied theory with many good examples in C). I recommend it for anyone who has passed tire intermediate C programming stage.
Until next time - keep programming!

• AC- POWER HUNGRY Whether you own an Amiga 500, 1000 or 2000
you'll want to feed it right. Fortunately we re here to help.
At Expansion Technologies we provide high quality expansion
products that are guaranteed to keep your Amiga growing happy
and strong, just check out our menu : If your Amiga has a
really voracious appetite, but your pocket book is on a diet,
try our Escort 30Mb SCSI hard drive at a 20Mb price.
Controllers, with a bus return are available for both the A500
as well as the A1000, Each accepts our 3.5 or 5.25 inch drive
chassis (available in sizes Lip to 80Mb) with fan and power
supply and is fully compatible with WorkBench 1.3. If you
prefer buffet, buy the kit and supply your own drive.
However you do it you'll enjoy lots of storage space at a great price.
Now thats serious fast food!
Escort Hard Drive kits A500 30Mb ......$ 699 A500 Kit 3-5 inches $ 339 A1000 30Mb ....$ 759 A1000 Kit 3-5 inches .$ 379 Call for other sizes.
For the discriminating pallet of the expansion hungry Amiga 1000 we have the ever popular Escort 2. It's 2 megabytes of no wait-state memory chat meets all the known standards and then some. It's also a uniquely designed vertical 2-slot card cage that offers incredible flexibility, Like the ability to upgrade to a scrumptious 4 megabytes of memory, or you can add a hard disk controller that uses IBM type hard drives, or an external power supply for the bus return or...well, you get the idea.
Truly a meal fit for a king!
Escort 2 (0k mem) .$ 339 2 megabyte upgrade card (OK mem) .$ 279 ST-506 hard drive controller card and power supply $ 399 Simply the best engineered 3 5 inch external floppy drive available for your Amiga, and it's 100% 1010 compatible.
The precision drive mechanism is ultra quiet and has the highest MTBF specifications. A low power CMOS design and pass through allows for easy daisy chaining too. Its low profile (1x4x8 in.)
Allows A500 disks to eject over the top, and it fits right under an A1000. Includes an extra long cable, heavy steel chassis and faceplate with dust cover. Why buy less than this Made In The U.S.A drive.
Notv you're cooking with gas!
Escort 3.5 in. Floppy $ 179 Feed your power hungry Amiga right- give it peripherals from Expansion Technologies.

Obecontirxjed _ To Order Back Issues, please use the order form on page 112 The Developing by Stephen R. Pietrowicz Beta Testing “Oh, that product is still in beta testing. It won't be available for another two weeks." How many times have you heard that before? Two weeks seems to be the amount of time everyone gives for of a product's release date. Well, what exactly is "beta testing" .anyway?
Beta testing is a period in the product development cycle when the product is sent out to independent testers. The testers report bugs to the developer and offer suggestions about the product. The developer fixes the bugs, and sometimes incorporates the tester’s suggestions. At the end of testing, the testers are either paid, or given a release copy of the new software.
It's important that developers have independent beta testers look at the product, because a developer may not try everything an ordinary user tries. Ask any software developer that has gotten bug reports from customers. People always come up with ways to use programs that the developer hadn’t even thought of.
Since independent testers haven’t followed the product through the development cycle, they have no preconceived notions of how the product should work. The developer can gain substanially from this arrangement by improving the product before it ships.
Some companies admit they do testing in-house. I think they’re really missing an opportunity to develop better products.
How should you, the developer, pick beta testers? That's a really tricky question. After all, you don't want to give it to someone who is going to pirate the program, or to someone who just wants the program and isn't going to be much help in testing.
The best thing is to distribute the product to trustworthy friends, and only to people with a genuine interest in your product. Make discreet inquiries to people you think may be willing to help.
It’s disheartening to send a product to a beta tester, and then to hear little or no response. Be careful who you pick.
Other developers may suggest reliable testers and testers you should avoid.
Once you’ve chosen the testers, send each a beta test contract. The contract outlines what is expected of testers, and also helps protect yourself.
The testers should have a clear understanding of what is expected: how to report bugs, how testers will be paid, the terms for breaking the agreement, etc. Once you’ve set up a relationship with testers, you might want to set up a BBS system to keep in close contact with them. A BBS can serve as a focal point where bug reports are submitted, new beta software is downloaded, and discussions about the current beta can take place. Services such as People Link can also be used this way. (In fact, that’s how I keep contact with developers when I beta test products.) You may want to give your
phone number to your testers, so they can call with questions.
Some problems are explained more easily over the phone.
Listen to your testers! If one or more of them is having a problem understanding how something works, chances are that future customers will have problems, too. Weigh each suggestion carefully. Is the suggestion something that should be added to the product now, or should you wait to add it to a future release?
The length of the beta testing period is up to the developer. It should be at least a month or longer. You're going to spend quite a bit of money for diskette duplication and documentation, so it’s in your best interest to test that software throughly. After all, you don’t want to spend more money duplicating disks for an update to fix a serious bug testers could have found.
Taking that extra “two weeks” for beta testing saves more than time and money; it also helps you deliver a better product to your customers. It takes a long time to establish a good reputation for your company and your products. It takes only one product to do damage to the reputation you work so hard to maintain.

AMAZING PROGRAMMING BASIC Linker by Brian Zupke It was 4:27 a.m. My eyes were bloodshot from staring at the unforgiving computer screen. After the 13th major modification to my latest BASIC program, it still wouldn't work.
I was running out of line numbers. It took forever to trace all the GOTO’s. 1 wondered if I had used a variable name in one of the new subroutines that already existed in the program. The pages of my reference manual were worn from verifying the memory locations I was POKEing around in. This is how I spent every night. I lost my job and my wife, and even my dog left me. My life was a complete mess. That is, until I found AB.
My friends (the few 1 had left) banded together and introduced me to the Amiga and AmigaBASIC. I picked up the AmigaBASIC manual, flipped through it, and saw the light. Line numbers weren't necessary, GOTO's were rarely needed, subprograms had their own local variables, and the language was so powerful that there was no need for me to POKE around. I was saved! No longer did I have to stay up all night debugging programs. I got a new job, my wife returned, and even my dog came back, (He ate my old computer though!) My life was renewed.
I thought I was okay. There 1 was, creating structured programs, creating subprograms, not using GOTO’s. I thought I had it all. Not so. I discovered other languages created executable files from programs and subroutines automatically. I was spending lots of time MERGEing the latest versions of my subprograms and cursing myself when I got the UNDEFINED SUBPROGRAM error because I'd forgotten to MERGE one of them.
I also found out that there are four fundamental program structures, of which AmigaBASIC has only two: the IF THEN ELSE block and the WHILE loop. Missing is the SWITCH CASE or, dare I say, computed GOTO (aaaacck!!) Structure and the REPEAT UNTIL loop. The REPEAT UNTIL loop is similar to the WHILE loop except that a REPEAT UNTIL will be executed at least once and a WHILE loop may not be executed at all. I feared I would lose control again, but I came to my senses: 1 had AB to save the day.
I decided not to live without these missing features, so I wrote a BASIC Linker program called BUNK. This program combines the individual routines from my program library to create an executable program. At the same time, it performs REPEAT UNTIL and SWITCH CASE macro expansions. That is, it converts those structures into statements AmigaBASIC can understand. I was in control again.
For those of you who are interested in adding these capabilities to your AmigaBASIC, read on.
In order to use BLINK properly, the rules and naming conventions below must be followed. They are necessary to guarantee that your programs will be linked and macros expanded correcdy.
Subprogram Calls:
1) All routines (programs and subprograms) must be stored in
ASCII format. This is necessary for BLINK to be able to read
and combine routines correctly. Although more disk space is
used to store each routine, you can use any text editor that
will save files in ASCII format. If you use the AmigaBASIC
editor, save your files with a comma and die letter A O',A”)
following dieir names so diey will be saved in ASCII format.
2) All routines must be located on the same disk or directory.
This collection of routines is referred to as the program or
source library'. The program library is used as the input for
3) All calls to subprograms must use the CALL statement.
Although AmigaBASIC allows a subprogram to be called by
specifying only its name, BLINK uses the CALL statement to
distinguish between a call statement and a statement label.
4) All subprogram names must end with “.MSB". This simplifies
BLINK’S task of identifying which CALL statements are
subprogram calls and which are runtime library or assembly
language calls. Note that the main program does not need this
extension since no routine will CALL it,
5) The subprogram name and its file name must be idendcal. If
they aren’t, BLINK will not be able to find the subprogram.
6) Only one subprogram call per line is permitted. If there is
more than one CALL on a line, BLINK will see only the first
REPEAT UNTIL usage: The sequence: REPEAT
- Valid statements UNTIL(condition) is expanded by BLINK to: RU
(x) - -1 WHILE RU(x) IF (condition) THEN RU fx) = 0 WEND where:
x -nested level of die REPEAT UNTIL loop. This will actually be
a number from 0 to 9- No variable x will be used.
1) The REPEAT and UNTIL statements must appear on lines by
2) The condition portion of the UNTIL statement must be a valid
BASIC expression that will yield a TRUE FALSE result when
evaluated. This expression must be enclosed by parenthesis,
and spaces are not permitted between “UNTIL” and "(”.
SWITCH CASE usage: The sequence: SWITCH(expression) CASE valuei CASE value2 CASE value-n DEFAULT SWEND is expanded by BLINK to: IF expression = valuel THEN ELSEIF expression = value2 THEN ELSEIF expression = value-n THEN ELSE END IF
1) All SWITCH, CASE, DEFAULT, and SWEND statements must appear
on separate lines.
2) For each SWITCH statement there must be at least one CASE
statement and only one SWEND statement. The DEFAULT statement
is optional. If no DEFAULT statement is used, then the last
ELSE block will not appear.
3) The expression portion of the SWITCH statement must be a valid
AmigaBASIC expression enclosed in parenthesis.
Spaces are not permitted between “SWITCH” and “(”.
4) There is no limit to the number of CASE statements that can be
in a SWITCH structure.
5) The value portion of the CASE statement must be a valid
AmigaBASIC expression ending with a colon It must be
compatible with the expression in the SWITCH statement.
6) SWITCH CASE structures may be nested in up to nine levels.
TRUE FALSE conversion: When this function is enabled in BUNK, all occurrences of upper-case only “TRUE” and “FALSE” will be converted to -1 and 0, respectively. If you link BLINK with this conversion active, the main program's statements: TRUE = -1 FALSE = 0 will be converted to:
- l = -1 0 = 0 which will cause a syntax error. Therefore, do not
link BUNK with this conversion active. The TRUE FALSE macro
conversion serves more as an example of what kind of
conversions are possible. I prefer to have the variables TRUE
and FALSE DLMensioned as SHARED in the main program as they are
in BUNK.
Entering the program: Since you can’t link BASIC programs until you've created BUNK (a small Catch-22), enter all of BUNK's subprograms as a single source. Use the test programs to verify that it is working properly (see instructions below on using BUNK).
Once the program is -working, save each subprogram under its proper name in your program library. BUNK should be able to link itself now.
Using the program: When you want to link a program, run BUNK from AmigaBASIC and enter the infonration requested by die program. You will be asked for the following items: Program name: the name of the program to be linked.
Library pathname: the disk or directory containing all of your AmigaBASIC programs and subprograms.
Program pathname: the disk or directory in which BUNK will place the linked program. The linked program will be saved under the same name, with “.EXE” added to the end of it indicating that it is executable.
Compress (Y or N): all comment iines will be removed from the linked program if requested. Only iines that have or “rem” or “REM” in the first column will be removed. This feature is useful for cutting down on the size and increasing die speed of a finished program. When BLINK itself is linked with no comments, its speed is approximately doubled.
TRUE FALSE Conversion (Y or N): all occurrences of upper case "TRUE” and “FALSE” will be replaced with “ -1 " and “ 0 ” respectively.
Once this information is entered, the program begins reading the specified program from the source library and storing it under its new name. During this transfer, BLINK searches each line of code for AmigaBASIC calls and adds the names of any it finds to a list of routines that will also lie transferred. After the main program has been processed, BLINK will begin transferring the next subprogram on the list. BUNK will also work on a program that has no subprogram calls.
BLINK prints the name of the source it is currendy scanning and linking. Once all the routines are transferred, die name of the new file is printed. If BLINK cannot find a subprogram in the library, it -will report the error and stop executing.
Debugging your program: When you're testing your newly created programs, be sure to make the final correction:; to the routines in your library rather than in the linked version.
Enhancing modifying BLINK: If you wish to add other macro-expansion conversion routines to BLINK, add them to the routine ScanModule.MSB. There are two sections of macro expansion calls in this routine.
The first consists of macro conversion routines that modify only part of a BASIC line (such as TRUE FALSE). A single BASIC source line can contain more than one conversion macro call.
(Note that the line may be altered by more than one conversion routine.) The other section contains macro expansion routines whose expansions take up more than one line. Only one of these can exist per line of original BASIC code. To add a macro expansion here, simply follow the “Future Macro” skeleton.
Conclusion: I kept the routines in BLINK as simple as possible, so they may not handle every possible condition. Since the code is somewhat simple, it should be easy to customize. Enjoy!

Your files are saved-even if you have completely deleted them from the hard drive!
EZ-Backup comes with an optional warning screen- We all tend to put off doing backups. EZ Backup s warning screen reminds you.
If you would rather no: be remtnded--you have the option to shut the warning screen off.
EZ-Backup prevents you from damaging valuable data- By checking the volume label. EZ-Backup keeps you from writing over important files.
EZ-Backup uses Standard Amiga format- Files are archived in standard Amiga format and work with all standard utilities.
EZ-Backup provides easy recovery of individual files A ample to use mouse-oriented program allows you to recover individual files.
Works with all Amiga-DOS compatible hard drives.
(Amiga-DOS version 1.2 or higher)
* Provides archive-bil utilities * Not copy protected
* Multi-tasking * Complete manual with examples
* Upgrades provided Ires for the first six months after program
* Free telephone support!
