Dear Amazing Computing, I have been an avid reader since Volume 1.1 and still find AC to be the number 1 Amiga magazine.
Your articles on Assembly (machine) language programming are most appreciated. I have been programming in BASIC and the appearance of Machine Language articles helped me make the decision to go with ML rather than "C."
The purpose of this letter is not just to praise your efforts but to contribute a little knowledge that I have acquired.
In Volume 2.4, Mr. Greg Douglas presented a short article on using function keys with MicroEmacs, as supplied on Extras 1.2. I finally got around to setting up an Emacs disk and attempted to create a BASIC program to accomplish what Mr. Douglas had done with his C program, build a custom file that Emacs would load.
Instead, in re-reading the Emacs documentation, I discovered the method for creating the config emacs_config file from within MicroEmacs.
The Quote Char option under the Edit menu is the key. Anytime you need to enter a control sequence first select the Quote Char option then type the control sequence. The Quote Char option is only active for one control sequence, that is if you wanted to enter AAAK for a specific function key, you would select Quote Char then type AA, reselect Quote Char and type the AK. (Control is represented by A).
Once you have defined all 24 keys Fl- F10, Help, 0-9,,,-, and ENTER, simply use the Save As function and save the Emacs file as config emacs_config in your root directory and the key map will be loaded when Emacs starts.
You could also use this same method and save other key maps and load them after Emacs is started with the "Load Keys" option.
One other error has been discovered in the documentation. It states that AJ will perform an indent function while in reality it simply opens a blank line in your text.
A warning, I was visiting files and creating files during this learning process and discovered that if you run out of memory for Emacs buffers you will get an "error in memory allocation" message and the only way out is to re-boot! Other tasks. Workbench, Etc. still seem to be performing normally, but Emacs is definitely in trouble.
I hope this bit of data will be of some assistance to other new MicroEmacs users.
Sincerely, Jim Thompson Dear Amazing Computing: As a new Amiga owner and a recent subscriber to your magazine, I find that I'm enjoying both very much. I particularly enjoy your articles on BASIC and your reviews of public domain programs. From my viewpoint as a beginner at all of this, I have a couple of suggestions which I think may make your magazine even more useful to a broader readership.
1: For greater ease and accuracy in entering type-in BASIC programs, a convention is needed to indicate the number of spaces to be entered at any given point in the program. Perhaps a box with a number in it to indicate the number of spaces to be entered would be appropriate. This would save a great deal of time and effort on the reader's part trying to count just how many spaces there are in a "blank" part of the code, particularly when the code is formatted so that the spaces go from one line to the next.
2: For a better understanding of the programs on the Amicus and Fish disks, a small article each month describing a selected program in some detail would be most useful. The article could include how to install the program, bugs to be alert for, and how to use it to its maximum potential, i have found many interesting programs on the disks but have spent hours trying to get some of them running when there has been sketchy documentation or none at all.
Yours truly, John M. Salimbene Ohio We appreciate your warm words and both of your suggestions are well received.

The "blank space problem" is tricky. We use a non-proportional type so all spaces and characters remain in a 1:1 ratio.
Adding special blocks to an already crowded code will be very difficult. As a second option, we will return to our previous practice of placing our published code on public domain software disks. We intentionally keep the cost of these disks low, and we hope their inclusion in the public domain will allow a greater number of users an opportunity to not only use the code as published, but to generate modifications and send them back to us for future disks.
On the second note, our new Public Domain Software editor, C. W. Platte, is attempting to do just as you have asked.
Pie will not only be looking at the newer additions, but he will continue to review older disks and their contents. Special instructions required for the more complicated problems will be an added asset to this column.
Dear Amazing Computing, This is for those neophytes, like myself, who have met with little success using the IEEE Double Precision library routines under Lattice 3,03.
The C-DEVEL: include libraries directory contains mathffp.h, which declares the mathffp. Library functions.
However, the double precision routines are not declared. The fix is to create a header file for the mathieeedoubbas.library called "mathieeedoubbas.h". The file should include the following listing: llfndef LIBRARIES_MATHIEE£DOUBBAS_H
* mathieeedoubbas.h ir ttt*********.************.** int
IEEDPFlxO; double IEEEDPFltO; int IEEEDPCmpO ; lnt lEEEDPTstO;
double IEEEDPAbs (); double lEEEDPNegO; double IEEEDPAdd ():
double IEEEDPSubO; double IEEEOPMulO; double IEEEDPDivf);
fendif LI3RARIES_MATHIEED0U3BAS_H This declares the functions
listed on pages 472-473 of the ROM Kernal Manual. Place this
file in the C_DEVEL:include libraries directory.
To use the functions, place " include libraries mathieeedoubbas.h " in the include section of your program and open the library as outlined in the ROM Kernal Manual. The mathieeedoubbas.library file, which can be found in Workbenchl.2:libs, should be included in your system disk's libs directory.
The routines are faster and more precise than the standard "C" versions of double precision arithmetic. If you do a lot of double precision number crunching, tty out these routines.

If you are as crazy as I am, and a gadget freak as well, read on.
MindLight 7 The Visual Aurcils Music Animation System Experience The Visual Aurals Music Animation System (VAMAS for short) by Visual Aural Animation is probably the most sophisticated personal computer-based color organ known to mankind.
Before the advent of computers, a color organ was simply a device that took sound input and blinked lights in response to certain frequencies. In the past, boxes that blinked in time with music were hits at parties and discos. Enter the Amiga, capable of amazing graphics, and the VAMAS.
The VAMAS package consists of a hardware device, a disk of software, and a thick soft-cover manual. The hardware consists of a circuit board enclosed in a round, clear-acrylic case called the MindLight 7. The MindLight 7 plugs into the second mouse port.
The aesthetics of the MindLight 7 are sure to please the user. It has just the right look to invoke the curiosity of onlookers, complete with two blinking LEDs on the circuit board.
The MindLight 7 receives sound input from either the sensitive internal microphone or a 3,5" stereo plug for input from a home stereo. The sensitivity and response to the sound input can be modulated using the three thumbwheels on top of the case.
By David N. Blank Sound is analyzed and processed in real time into four "MindLight channels" and one "Wavelength channel."
The MindLight Channels are: "Bass Intensity & Treble Intensity," "Overall Intensity & Overall Frequency," "Bass Intensity & Bass Frequency," and "Overall Intensity & Treble Intensity."
The Wavelength channel gives a reading of the sound input's exact frequency or wavelength.
As impressive as the MindLight looks, its software is even more amazing.
The software provides an overwhelming assortment of features used to visually animate the data collected by the MindLight 7. Every component of an animation can be stored in an "Environ" for later recall. Ten Environs are stored in memory for instant access, and an unlimited number may be stored to disk. The manual breaks each animation down into four parts; I'll take the same approach in describing the software.
The first component of the VAMAS software is the "vista." A vista is the description of the backdrop for each animation, and how the backdrop will interact with the animation. The VAMAS is designed to work with an optional external video signal input from a genlock device. The vista may be changed to include a mask to determine where, in relation to the other parts of the animation, the video input will be displayed. The vista also determines the location in an animation (foreground or background) of an IFF picture.
The second part of an animation is a "visual." The manual provides an excellent definition: "A visual is a sound-responsive pattern generation scheme with distinguishable characteristics."
The eighty-four visuals available may be divided into three groups. The first group is the Kolai (collage-like) visual. These visuals manipulate a single object in response to the sound input. The object can be either a pre-programmed geometric shape or an IFF brush. The second type, the Mozai (mosaic-like) visual, uses many small objects to form moving and changing patterns on the screen. I have intentionally shied away from describing any individual visuals because they really have to be seen to be understood and appreciated.
The last group of visuals could be described as the miscellaneous set.
Two of these miscellaneous visuals have serious uses. The Scope visual _(continued on page 10) AT LAST!

The Atune visual displays, within a musical scale, the dominant frequency as a musical note being received by the hardware.
The last miscellaneous visual is a sort of random mode, called "Evolve." In this mode, the software randomly chooses different visuals and effects in response to the music. If a certain combination strikes the eye, the user can freeze the "evolution" at any time and save the current parameters.
The next portion of the VAMAS software is the Fader. Just as the user is given exacting control over what is placed on the screen, myriad options exist to determine how visuals are removed from the screen. These are called Faders. The user may choose to have previously drawn effects fade from the screen or be removed all at once (blanked). The screen can be faded or blanked to and from the background, foreground, IFF image, or video input. An interesting variation on this theme is the Kolai fader. This fader uses the same objects that normally decorate the screen in a Kolai visual. The usual
complement of options is available here to determine which portion of the visual should fade, which can produce some spectacular effects. The Kolai objects seem to act as windows to another part of the animation. For all Faders, the user controls the speed of fading and blanking, The Fader can be synchronized with a MindLight channel to fade or blank in response to the music.
If all this does not suggest a mind- boggling set of options, add to them the set of effects under the Modifier heading. As its name suggests, it modifies the current visual or fader.
The list of modifiers is long. They include: selection of Kolai and Mozai objects, the speed and selection of fader type, the colors used in an animation, software sensitivity and synchronization, and miscellaneous effects. Each one of these modifiers has a different set of options. For instance, the color modifier allows the user to dictate the colors used in an animation, the speed of color change and or color cycling, the range to cycle, and which of the three available palettes to use. The user can also choose effects such as scrolling and the scrolling modifier, called bit splitting.
Bit splitting is an effect whereby each pixel is split into two component- colored pixels which then move away from the original, There are several different ways to scroll and bit split; the user is left to choose. Speed and synchronization controls are also provided. The VAMAS also provides a modifier called the V-number (a set of variations on a visual numbered from -1,000,000 to +1,000,000). The manual provides an example of how different V-numbers can show totally different aspects of a single visual.
As we run down the options and features of the package, two other miscellaneous features should be noted. The Visual Aurals Music Animation System is capable of performing its magic using the entire range of Amiga graphic resolutions, including HAM and overscan. If you tire of the Amiga responding strictly to outside sound input, you can invoke the second interesting feature. To provide a two-way street, the software has a built-in MIDI sequencer and sync support for driving external synthesizers and drum machines connected by a MIDI interface to the Amiga. An interface is not included in
the package, but any standard Amiga MIDI interface can be used.
All the usual VAMAS operations run simultaneously with MIDI operations.
I have very few gripes with this package, and they are minor. The first is the location and size of the MindLight 7. In place, the MindLight 7 partially overlaps the expansion port of the Amiga 1000, which is annoying to users who have attached expanded memory via the expansion port.
My second problem lies with the manual. It is fairly complete, but a bit disorganized. This can be a big problem for someone using a new product, but in this case it is much less troublesome. Digging through the manual to locate information adds to the adventure of exploring the seemingly endless options. My last caveat: the sophistication of this package has made it a bit high-priced for any but the most devoted gadget freaks.
! Think the term "adventure" is the key. At first, the number of options seems to reek of overkill and can be a bit overwhelming. This impression is toned down by the sense of adventure and exploration the manual instills. It begs for experimentation; there is no wrong set of keys to push or wrong option to invoke. At worst, the user is faced with a blank screen, for which the manual offers several remedies.
There is also a feeling that all the options a user could possibly want have been included; it just may take some experimentation to produce the desired effects. The Evolve visual also helps to suggest new and different combinations every time it is invoked.
The end product of this plethora of options is a lasting interest value seldom found in recreational computer packages. I am also told that Visual Aural Animation is hard at work designing a developer's kit to allow programmers to design their own applications and animations based on input from the MindLight 7. A Visual Aurals 3-D package is being designed under the direction of the author of popular public domain 3-D game Triclops. These two products should be released in the months to come.
The Visual Aurals Music Animation System seems to have a practical value approaching nil. But it is definitely one of the most unusual and entertaining Amiga gadgets around.

Central Coast Software 268 Bowie Drive, Los Osos, CA 93402 * Telephone (805) 528-4906 • FAX (805) 541-4745 Dealer Inquires Welcome New Cli Window Interactive Startup-Sequence i by Udo Pernisz There are two basic environments from which the Amiga can be operated, and they divide the world of Amiga users into two camps. From the Workbench, the Amiga is operated by the mouse. This popular operation mode selects from the icons, menus, and gadgets of the Intuition interface. The Command Line Interface provides an alternative environment which affords much more flexibility and power in handling
files and functions on the Amiga. The CLI is available under AmigaDOS, the Amiga disk operating system. Here you type commands from the keyboard to the screen where they appear at the prompt, usually as a number followed by the angular bracket (1 ), In the commands to follow, this prompt will not be repeated with the examples for command lines since the prompt is provided by AmigaDOS. The commands and functions AmigaDOS understands are described in the AmigaDOS User's Manual.
After the Workbench disk is inserted, and the Amiga wakes up, the screen displays an AmigaDOS window. After a few seconds, this window closes, and the familiar Workbench appears. While the AmigaDOS window is open, the Amiga executes DOS commands from a file called Startup-Sequence found in the :S directory of the Workbench disk. The Startup-Sequence is a command file containing a list of instructions for AmigaDOS to execute. They are executed in order, just as if they were typed from the keyboard. The Amiga is designed so commands in the Startup-Sequence file are automatically executed when
the computer is restarted or reset with the CTRL LeftAmigaKey RightAmi- gaKey combination.
In its original form, the Startup-Sequence executes the instruction lines LOADWB and ENDCLI. The first instruction is a program that opens the Workbench environment. The second is a DOS command which closes the CLI window.
You can modify the Startup-Sequence by adding commands such as “ECHO text " and "RUN Clock." "ECHO text " displays text on the screen, while "RUN Clock" displays the clock, normally invoked by clicking on its icon from the Workbench. Depending on your particular applications or various work environments you need, you may have many different Startup-Sequences on various program disks. (For example, you might have a Startup-Sequence which brings up the Amiga with a game or a word processor running.)
When using the CLI mode, you could end up with elaborate command files to automatically configure the Amiga with utilities and functions. There are two problems with this approach: (1) Once a customized environment is created by a specific Startup-Sequence, it can be changed only by typing in additional commands, or by changing the Startup- Sequence (e.g. with a line editor) and rebooting the computer. (2) An all-encompassing startup-sequence may take a long time to complete because AmigaDOS commands are disk resident (i.e. all commands are actually small programs present in the :C directory
and each command is loaded into memory before being executed).
In most cases, you need only the basic CLI or the Workbench. It would be convenient to have a startup process flexible enough to allow you to choose interactively between various options by typing a suitable response from the keyboard.
Of course, you could put the Amiga into the CLI mode, then perform all the desired functions from the keyboard by typing in suitable DOS commands. However, this method requires a great deal of typing every time you start up the machine. As an alternative, you can execute a batch file.
A batch file is simply a text file containing a sequence of AmigaDOS commands. Typing EXECUTE along with the name of a batch file causes the Amiga to execute each command in the file as if you had typed the commands from the keyboard directly into a CLI window. You could customize your environment by executing a series of appropriate batch files. The only problem here is, you have to remember the names and functions of all your batch files.
This approach still requires a fair amount of typing.
There is a solution, though. You need a way for a batch file to display a list of options, thus allowing the user to choose from these options with just a few keystrokes. This is indeed possible with an EXECUTE command that performs what is called a parameter substitution. Essentially, this means AmigaDOS uses what you type in from the keyboard in place of a parameter specified in a batch file. This feature is explained, with many examples, in the AmigaDOS Manual. Here is a brief review. The format of the EXECUTE command is: EXECUTE1 CommandRle Argument Argument is passed on to the command
file aptly named CommandFile. Argument can then be tested and acted upon by the other command sequence control statements available in AmigaDOS. (A discussion of the powerful command files that can be configured for the Amiga appeared recently in Amazing Computing V3.1, p.59.) Since the Startup Sequence is executed automatically before the keyboard is active, a problem arises when applying this feature to the special batch file named Startup-Sequence, It is impossible to type in the whole line as required by the command format.
Is there another way of utilizing parameter substitution?
The concept of an interactive Startup-Sequence hinges on the answer to these questions: How can a parameter pass a value from the keyboard to an executing command file?
Can the EXECUTE command turn to the keyboard for Argument input during execution of a batch file?
Yes it can, through a feature associated with using the question mark as an argument to an interactive CLI command. (This is not the question mark in a pattern such as " ?" Used with the LIST command.) An example using the "?" Is the DIR command. (See the AmigaDOS Manual.) If you type "DIR" from the CLI, you get a sorted listing of directories and files in the current directory. This command also takes arguments, including the filename and several other options. But when you type "DIR ?" You get a display of all possible responses to this command in the form of a command template. When
followed by a colon, the display indicates the Amiga is waiting for one of the possible responses to be input from the keyboard. So, although the command line was terminated by pressing the RETURN key after the question mark, the CLI has activated the keyboard for entering a parameter value. (The LIST and DATE commands are similar to DIR.)
The important point here is that the "?", as an argument, invokes the keyboard for input to the process called by the command. It doesn't matter whether the command was issued by the keyboard (as in the example above), from another command file, or by EXECUTEing another command file (either from the keyboard or from a command file).
Therefore, if a command file contains a line of the form EXECUTE File Name ?
(where FileName is another command file set up for parameter substitution), the screen will, by making its first line .KEY Patometei_Name).
The screen will display Parametef_Name: when the line with the "?" Is being executed.
It then waits for the input of its value from the keyboard.
Let's apply this example to a simple Startup-Sequence that allows you to choose between two basic modes: the Workbench and the CLI. All files are put into the boot disk's :S directory (although files in the root directory may also be used, see later examples). Since a file by this name in the ;S directory will be automatically executed when the Amiga boots, the name of the principal file (see Listing 1) must be Startup-Sequence. This file executes a second file, called OptSys (see Listing 2), You can modify an existing Startup-Sequence in the :S directory using ED. ED is available as a :C
directory command on the Workbench disk. Before you try the files listed here, make a copy of your original file if you want to restore the previous state. To create the file OptSys, type ED OptSys from the CLI and enter Listing 2.
Upon booting, the Startup-Sequence first displays the option list (five lines of ECHOing) and then executes file OptSys.
The "?" Causes the input template (the variable name) to be displayed. Thus, . Select: appears on the screen beneath the line with the responses to the two options (the was supplied by the operating system). This particular variable name was chosen so that it functions as a written prompt for keyboard input. You could call the variable VarNaml, but it makes more sense to give it a meaning associated with the file's function.
There are many ways to process the keyboard entry in the command file OptSys. For instance, you could first test for the empty string (RETURN key only) with the command line IF * Select ' EQ " where the quotes around " Select " are essential. There are also ways to define a default within the command file (see the AmigaDOS Manual).
(continued) For more complex option structures, the first file OptSys here) may in turn, call other files and also pass arguments on to those. You may use more than one argument. The format of the .KEY command allows an argument list with several arguments. All these may be entered, separated from each other by commas (not spaces) in the very first option request. The responses to a variable list are separated by single spaces (not commas), however.
The next example shows a possible file arrangement that makes use of this feature. The modified Startup-Sequence (Listing 3) reflects the larger number of options. The first file, now called OptSysl (Listing 4), expects two parameters, Select and Option. Both are optional, so you can answer with a single RETURN key press. Incidentally, special conditions familiar from the command templates can also be applied: adding the suffix A to a parameter name in the .KEY statement makes it a parameter for which a value must be supplied.
You select the default by pressing the RETURN key. This gives the basic CLI, since no other commands are invoked.
OptSysl will be the only file executed.
The second file uses a public domain utility (SHELL by Matthew Dillon) to enhance the CLI and add convenient features, such as command memory, command line editing, and function key definitions. SHELL is called up from OptSys2 (see Listing 5). When you select it, you can also opt for entering the date and time during startup. Another option available when you select the Workbench mode (Intuition interface) is a small auxiliary CLI window in the lower right-hand corner of the screen. In this window, you can do file handling from the keyboard, while using the icons for program selection with the
The reason for processing the options in more than one file is that you can design a system of command files with a logical structure resembling a one-sided decision tree. In this way, options requiring only a few commands are executed directly, while lengthy options are dealt with by executing another command file. Thus, the file OptSys2 in Listing 5 is only loaded if more than just the bare CLI is desired. This operation saves time, as a command file that uses the .KEY statement is copied into the :T directory before being executed. OptSys2 also could be further divided. Still more speed is
gained when disk access is further reduced. This can be done by copying frequently needed files into a RAM: disk, and by providing for buffer space with the ADDBUFFERS command available on Workbench VI.2. The programs given in Listings 1 through 5 are not optimized in any way; they just provide examples illustrating the two concepts that make the Interactive Startup-Scquence possible. This can be combined with the command language available under the CLI to set up a sophisticated program structure with which a wide variety of systems configurations can be controlled.
I'd like to thank John Kennan for clarifying discussions, and for suggesting that I write this article.

By Steve Hull People Link: St.Ephen Genie: Light Raider Roger Rabbit is the improbable star of what some sources have described as Disney Studios' most ambitious movie project in years; a quantum leap in live action animation technology as significant in its genre as Fantasia was in its time. The movie's budget is astronomical and most individuals involved with the project have been bound with heavy nondisclosure agreements. The movie's producer?
Steven Spielberg.
Needless to say, details on the movie aren't exactly crawling out of the woodwork, but this much is known: Roger Rabbit mixes live actors with cartoon characters a lot of cartoon characters every character in the Disney portfolio, and many characters from other studios. New special effects have been engineered to give the cartoon characters enhanced three- dimensionality.
What's all this got to do with Amiga games? Well, for months, Disney negotiators have been trying energetically to enlist a software producer to design a video game on the Roger King of Chicago by Mindscape Rabbit theme. A big budget movie, lots of special effects, Steven Spielberg you'd think this would be the kind of project any software house would jump on, right?
Wrong. Virtually every major software producer who has been offered the project has turned it down. When investigating the reasons, the same three factors keep coming up: Disney expects the software producer to absorb the costs of production, Disney expects a large cut of the profits, and Disney wants the game done yesterday. "Disney thinks since they have such a hot property, companies should pay to produce it," one developer told me. "Companies don't understand that!"
Not everyone involved with the movie is gung-ho on the videogame idea.
Spielberg is reportedly against the game he feels it won't be done right, Considering the debacle over the Atari 8-bit version of ET, his concerns are understandable.
Roger Rabbit and why is he so many software developers crazy?
Who is driving At any rate, Roger Rabbit: The Game is far from dead. Negotiations are still underway, and I may be overstating myself by saying Disney has met its match. But they have certainly found a producer who is ready to "go to the mat." Film at 11.
Forecast for Summer: HOT!
Accolade has promised the French import, Bubble Ghost, by the time you read this. You play the part of a spirit who must guide a fragile bubble rep resenting his soul through obstacleladen mazes by blowing the bubble around.
Rainbird Software, producer of the successful adventures The Pawn and Guild of Thieves, has unleashed yet another title on the unsuspecting world. Jinxter is an original adventure that takes place in the jinxed country of Aquitania, where you try your hand at restoring good will against the best efforts of the evil Green Witches. The graphics aren't quite up to the quality of previous Rainbird titles, but if you like British humor, Jinxter will have you on the floor.
Rainbird's long-awaited Universal Military Simulator is nearing completion, and if it's half the game they're promising, it's going to be an exciting ride. UMS allows joystick generals to recreate the greatest land-based military engagements in history on the computer screen. Included among the many scenarios are the battles of Gettysburg, Hastings, and Waterloo; each researched right down to the armaments and geography. You may reenact these battles as they actually took place, or change the scenarios even pit armies from different conflicts against each other! Rainbird says UMS'
three-dimensional gridded landscape will allow players to zoom in for views at any angle. Universal Military Simulator is scheduled for a late spring release.
(continued) Another military simulation is due out soon from a most unexpected source Cinemaware! Cinemaware's Bob Jacobs describes Lords of the Rising Sun as "a spiritual descendant of Defender of the Crown ' Lords is a game of territorial conquest set in 12th century Japan. The map stretches across three screens. Though Lords is a war game, the playfield is not the standard matrix of hexagons and hieroglyphic symbols. Instead, game play takes place in real-time on a map "that looks as good" as the detailed map of Britain in Defender of the Crown. Storm clouds drift across the island,
obscuring action; typhoons and tsunami keep things from getting stale.
As of mid-March, Cinemaware's 3 Stooges is reportedly "two bugs away" from shipping; programmers are still tweaking to get it to run on 512K, one- drive systems. I previewed this title at Cinemaware's southern California "studios;" I don't want to give anything away, but the opening sequence is worth the price of admission. Also promised for release by the time you read this: Rocket Ranger, a Nazis-from-Space pulp sci-fi story complete with a jet-pack equipped hero and the standard Cinemaware well-upholstered females. Cinemaware has written their own disk operating system for this one; it is
reportedly three times faster than AmigaDOS (I know that's hard to imagine- snicker).
The disk, by the way, is not copy protected- the game includes a Decoder Ring!
Later this year for Cinemaware: a "revolutionary" sports simulation, and a sci-fi title that promises to ruin your picnic in a big way.
Sometime this month Epyx expects to release Dive-Bomber, 4x4 Off-Road Racing, and the Amiga version of California Games. Add these titles to their recently-released Maxx-Out!
Game, Death Sword. The Maxx-Out!
Series is intended for 10-16 year old gamers, and is appropriately heavy on the action and excitement. C eath Sword is a sword fighting contest set in medieval times. Your goal is to defeat successive waves of opponents and rescue The Beautiful Princess (Karateka with a sword, methinks). A real treat awaits the gladiator skilled enough to behead his opponent; a gargoyle scuttles out of the shadows and kicks the head out of the way!
Yeah, the kids'll eat it up... Psygnosis has announced the release of Obliterator for late spring.
Obliterator's description sounds a little like Star Trek-Meets-Alien: a strange and sinister craft materializes in Federation space, threatening defenseless Earth. You play the part of Drak, a genetically-supercharged hero who beamed aboard the alien vessel to wreak a little good-natured havoc. I'm looking forward to this one.
Psygnosis has acknowledged that Terrorpods has trouble with the German keyboards shipped with the first Amiga 2000s, and a fix is in the works. While they're fixing the keyboard routines, programmers are planning to incorporate 68010 68020 support. The upgrade will be available free to registered owners.
Microillusions is aiming at a May release for Turbo, the third release under their One-To-One series. Not strictly the racing game some people had expected, Turbo is closer to the arcade classic Spy Hunter in its look and strategy. As has become standard fare in Microillusions' One-To-One series, Turbo may be played against the computer, or a human opponent either head-to-head or via modem.
Although the first One-To-One title, Firepower, has been quite successful since its December release, producer Reichart Von Wolfsheild is already planning an upgrade to squash a few bugs and speed up the action. A more extensive revision to the second One-To-One title, Galactic Invasion, is also planned. Good thing Galactic Invasion's rudimentary graphics and ho-hum gameplay are a sorry disappointment after Firepower. Improvements are in the works, including better graphics and the ability to land on the planets. Work on both revisions for games is scheduled to begin as soon as Turbo is
It looks like Microdeal has become the latest victim of the SCA disk virus the first shipments of the Amiga version of Time Bandit are infected.
Kudos to Brian Meadows' excellent public domain virus checker, View- boot, for finding this one. You can drop Brian a thank-you note at the Magnolia BBS, (205) 854-6407. As for your disks, the normal "cure" running the AmigaDOS Install command will render Time Bandit unusable. Return your master disk to Microdeal for a "sanitized" replacement!
Game of tlie Month Since its inception, Cinemaware's games have tended to polarize people some people love the movie metaphor, others can't stand it. While it's true that past Cinemaware games have tended toward flash at the expense of solid gameplay, I will let other reviewers tell you how much they hate King of Chicago. I've had a pretty good time with it.
For those unfamiliar with Cinemaware's premise, its intention is to do text and graphics-with-text adventuring one better, allowing the player to participate in a "movie" whose plot changes with the player's response to situations. In Sinbad and the Throne of the Falcon, for instance, winning the favor of the devious Libitina goes a long way toward success in your quest; anger her, and she will send an assassin after you.
The graphics and sound necessary to do this convincingly require a lot of machine overhead. There's no getting around this, and for King of Chicago, Cinemaware states the requirements on the box: 512K RAM and two drives, or a megabyte of RAM and at least one drive. Don't even try this game on a 512K, one-drive machine.
King of Chicago's increased hardware requirements result from the level of graphics and sound in the game.
According to Cinemaware, over a megabyte was used for the graphics alone. The first time I played, it seemed as if my external drive accessed more-or-less constantly, slurping a constant stream of graphics, and especially sound, off the disk.
King of Chicago is set in the Windy City in the 1930's (gangsters' heyday).
Capone has just gone up the river for income tax evasion ( &AS @*1 clever coppers) and the town is wide open for opportunistic young thugs like "Pinky" Callaghan. You control Pinky's actions (well, more or less control them more on that in a minute) as he sets out to expand his domain from Chicago's northside to the southside. But you can't expect the boys from the west side or the Loop to just sit around polishing their tommy guns.
The game boasts the richest cast of characters, both in number and substance, of any Cinemaware title to date, This is almost a backhanded compliment when compared to the lush characterizations that have long been standard in such products as Infocom's text adventures, but then again, a picture done well really is worth a thousand words. It's one thing to describe a look of scornful disdain; it's another to actually see the character's eyes narrow coldly and his lip curl.
King of Chicago goes farther than its predecessors in overcoming a problem that has plagued Cinemaware titles from the beginning: lack of repeated playability. I enjoyed Defender of the Crown when it was initially released, but I'll admit the only time I'll take it out is to use it as a graphics demo for friends. If you know what you're doing, you can finish the game in about 15 minutes.
King of Chicago overcomes this weakness by introducing elements of randomness from one game to the next. The basic plot remains the same; you must wrest control from the Old Man, win over the gang, and systematically capture Chicago a region at a time. How you do this, however, varies from game to game. For example, you might play three games where pressure and intimidation is enough to cause the Old Man to pack his bags. On game 4, he'll stand up to you and before you know it, the boys will be be fitting you for cement overshoes. Changes in plot, personalities, and loyalties from game
to game mean that you not only get a chance to try new strategies to survive, you will have to.
The game has another interesting feature not found on previous Cinemaware titles. At several points the game stops as Pinky ponders two or more alternative actions, illustrated by cartoon-type thought balloons. You choose the course of the plot by clicking on one of the thought balloons, and the game continues. However, if you don't choose an alternative, or take too much time deciding, the game selects for you! Thus, the first time you play King of Chicago, you might not want to play at all just let the game play itself in the form of a most elaborate demo!
King of Chicago has a lot of plot twists; after playing a dozen games, you're likely to run across new story elements. No matter how it works out, the game is a balancing act; you may be the Boss, but you still need to make management decisions like how much to squeeze the speakeasies, rackets and gambling joints for income.

The game's graphics are very good, the sound effects are adequate, and the music is excellent. There are several arcade type challenges woven into the story. Some, like the gunfight with the southside gang, demand as much in the way of reflexes as any arcade (dare I say?) Shoot'em-up. Other sequences, such as the blow-the- doorknob-off segment, are just flat dumb.
King of Chicago is not without its flaws. During some points in game- play, lengthy dialogues go on between characters and all you can do is watch.
This is fascinating at first, but as you might expect, it tends to get old after repeated sessions. This flaw is partially redeemed by the game's "fast forward" feature: holding down the left mouse button allows you to zip past repetitive segments.
Part of King of Chicago's challenge can be second-guessing your own character. There are occasions, for instance, when you will instruct Pinky to cool it only to see him become more aggressive! There may be times when you find yourself wondering: hey, who's playing this game, anyway?
As noted on the box, King of Chicago contains some strong language. Much of the profanity is awkward and self- conscious; "I say let's hit that damn south-sider barbershop." While 1 would not go so far as to recommend Cinemaware perform a global search- and-replace with more appropriate phrases ("dagnabbit" has a certain ring to it), it should be noted that the movies after which King of Chicago is patterned did not require profanity to get the point across.
All in all, these shortcomings arc more in the line of "growing pains."
Nobody has tried to do what Cinemaware has done, and there are bound to be a few bumps on the way up that steep learning curve. Like the titles before it, King of Chicago is less a real movie than a "preview of coming attractions." But even there, it has far more substance than its predecessors. Five years from now, King of Chicago will likely seem as quaint and simplistic as the vintage videogame Pong seems today but for now, it's an original and intriguing look at the shape of games to come.
Invasion of the Ii-Gamea Did you ever notice those, shall we say, "off-brand" Amiga games tucked away on a far shelf at your dealer, and wonder if they were any good? You know the ones I'm talking about normally imported from Europe, they come packaged in small plastic boxes slightly larger than an audio cassette, with inexpertly translated descriptions and slick cover illustrations that cannot possibly represent anything in the game itself. Though these games are priced lower than titles from most main-line companies like Mindscape and Activision, nobody likes to gamble $ 20 without knowing
what they're going to get. So, as a public service of this column, let's take a look at four of the "second stringers" Space Battle, Fortress Underground, Persecutors, and Emerald Mines.
Space Battle, produced by Digital Dreams, is a competent rendering of the coin-op classic, Asteroids. The object of the game is to clear an asteroid field by blasting miscellaneous space debris to bits the challenge being that blasting big rocks produces little rocks. These smaller asteroids can be dispatched, but so may you any impact to your fragile craft is fatal. You may maneuver anywhere on the screen in a realistic simulation of space physics; once you have established forward momentum, the only way to stop is to rotate your ship and fire your engine in the opposite direction. Pulling
back on the stick sends you into hyperspace, which can get you out of a tight spot. But since it places your ship randomly on the screen, it can also put you in one.
Standard features such as solo, team, and competition modes are supported; an extra ship is awarded at for every 5,000 and 10,000 points accumulated.
You arc also awarded a ship for touching a quavering iridescent bubble that floats periodically by. Hostile saucers appear from time to time to fire a few ill-intentioned blasts your way. High scores are saved to the disk.
Space Battle's gameplay is very good, but it does have one annoying bug.
Your ship may drift entirely off the screen for seconds at a time! While the ship has left your view, it has not left the game and wherever it is, there are asteroids there too. When your ship floats off the top of the screen and you hear a *KABOOM* out of nowhere, you know you've bit the intergalactic dust somewhere in the twilight zone.
Fortress Underground is an engaging arcade challenge along the lines of the 8-bit game. Fort Apocalypse. It comes with very sparse documentation, but it doesn't need much your mission is to pilot a helicopter through a huge underground cavern to destroy a hostile power station. Did ! Say huge?
Kingsoft, the game's producer, claims it covers 640 screens. Any volunteers to test that?
Underground's graphics are functional; that's about all you can say. The first time I played, 1 was reminded of some of the better magazine type-in games for my old Atari 800. The sound is worse,: thoroughly unconvincing beeps and plinks that would insult any self- respecting Commodore 64.
Fortunately, its gameplay redeems Fortress Underground. You begin with seven helicopters, and must wind (continued on page 22) Aladdin was expecting light but what he got was magic.

A chart in the lower-left of the screen maps your progress. You must also keep an eye on your gas gauge, and refuel when necessary.

Persecutors, a German import produced by Softgang, is the most graphically appealing of the four and the least playable. The first challenge you will face is figuring out the object of the game. The documentation on the packaging is vague and the short blurb displayed at boot-up does not help. Phrases like, "push stick as often as possible, else the score will be decreased," have lost something in translation.
My first try at this game was fast and decisive. I went through all 15 lives without the slightest idea what had happened. "Play Again?" The game prompted. Play? I thought, "is that what I just did?"
The object of Persecutors is to navigate a small spacecraft through each of the 65 levels of play, dispatching waves of colorful alien baddies that randomly wander the screens. You must also avoid protected zones, which will vaporize you on contact. The problem is, these zones are invisible and seemingly unrelated to anything on the screen. Displays at the bottom of the screen show your score, level, remaining lives, and a number corresponding to a label which reads "BLA" which I still haven't figured out.
Persecutors is a thoroughly incomprehensible game. Pass it by.
There comes a point in every reviewer's career when he is faced with hard decisions Kingsoft's Emerald Mines is a case in point.
Should I tell you that Emerald Mines is the biggest dog that ever wore a flea collar, and save you grief, or... No. I must tell the truth, though some of you will curse me for it. Emerald Mines is a fine contest along the lines of Boulderdash, and like its predecessor, has caused more than its share of hapless victims to cross that fine line separating addiction from compulsion.
Take it from someone who knows.
The premise of Emerald Mines is simple; you play the part of a miner whose job is to burrow through the ground in search of green and blue gems. But nothing worth having comes easily; there are a lot of ways to get yourself noisily nuked. Rattling bugs and little green antenna-waving robots wander the underground, as do menacing gray "flyers," and the "eaters" odd little round creatures that look like Sunkist oranges with fangs. Contact with any of these is fatal, but you can avoid them, or go on the offensive by dropping boulders on their pointy little heads. Of course, that goes both
ways boulders work on your pointy little head too.
That's only the beginning. Other obstacles include oozing green amoebae, acid baths, and the clock you have only a set amount of time to complete a level. Among the tools you may use are two kinds of explosives, and keys, (if you can reach them.) One player mode and two- player teamwork is supported, and there arc over 100 levels, Graphics are only so-so, but the digitized sound effects are well-done and imaginative. As for its gameplay, this one gave me the worst case of One-More-Game syndrome I've had in months! You know the symptoms sleepless nights, unpaid bills, indifferent
spouses...Don't say you weren't warned.
I have only one gripe with Emerald Mines, and it is a relatively minor one.
All of the games I have reviewed this month use disk-based copy protection, but Emerald Mines really takes things to extremes; the way my internal disk drive buzzed and vibrated, I was afraid it was going to leap out of its case! No apparent damage done, but there's got to be a better way to protect software.
Well, it looks like I've worn out my welcome for another month. Goody, get back to those games...like they say, it's a dirty job, but someone's got to do it.

AMAZING REVIEWS W0®@©§S(3[?@ §=® 2„® by David Hopkins The Amiga got off to a bad start.
Commodore made a machine with incredible graphics and sound capabilities, but they didn't know what to do with it! There just wasn't a niche for the Amiga. Then came desktop video, Desktop video is to the film industry what desktop publishing is to the printing industry: an easy, inexpensive way to get a job done. Animations and effects previously costing thousands of dollars can now be created for hundreds or less!
A major video product for the Amiga currently on the market is Videoscape 3-D by Aegis Development. Nothing short of incredible, VideoScapc took the Amiga world by storm. True, it's not for the novice user, as the packaging clearly states, but the rewards are numerous for those willing to spend time to learn.
Now, Aegis has announced Video- Scape 3-D 2.0. When Aegis called and asked if I'd be interested in a preview, I didn't know what to expect. What incredible new things did Allen Hastings have now?
After a few days of exploring 2.0, I'm even more addicted to VideoScape.
Let's take a look at the complete Videoscape 2.0 system, and I'll point out the many new features.
Control Window The Control Window is VideoScape's main screen. It consists of four "panels" and a menu bar. The Object Description Panel allows you to load an object, load a movement file, and position the object. You'll also find the number of points and polygons used in the objects you've loaded. The number of points and polygons available is limited by the amount of memory in your machine. A 512K system can use about 600 points, but Videoscape can handle up to 32,000!
The Object Description Panel also gives you the option to Metamorph the last two objects loaded. The only catch is that the objects must have the same number of points.
An important new feature here is "Hierarchical Motion." It allows me to load a planet as the first object, load a spaceship as the second object, then tell VideoScape that object one is the "Parent" object. This feature makes it much easier to have the spaceship orbit as the planet moves.
Next is the Camera Motion Panel. As the name implies, this panel controls the camera. A path may be loaded for the camera to follow, and the zoom can be changed. The number of frames and tweens (groups of consecutive frames describing a camera motion) are shown here, as well as an option to pause the animation after generating each frame, which is important for recording an animation to a VCR capable of single-frame editing.
A terrific addition here is the 'Track Object" selection in the load requester.
By telling VideoScape which object to follow, it keeps the camera pointed at it. This feature could be used to track a speeding race car, for example.
The Viewing Options Panel lets you choose your display environment. An animation can be solid or wireframe, in any of four resolutions ranging from 352 x 220 to 704 x 440. The sky and ground colors may be selected and backgrounds and foregrounds can be loaded. Three light sources have been added, so a total of four may be used, each with a different location and intensity. VideoScape now also recognizes the PAL video standards, and adjusts its resolutions as needed.
The fourth panel is the Scene Panel.
The Scene Panel is actually four buttons across the bottom of the screen. These allow you to load a complete animation setting file (object, camera motion, etc.), play your animation, save it, or quit the program. When you play the animation, a separate screen is set up according to your settings. If no camera motion was loaded, the numeric keypad is used to move the object around, or to store a single frame as an IFF picture.
VideoScape's menus have undergone the most changes. The amounts of remaining CHIP and FAST memory are now displayed constantly. In the Project Menu, a "Clear" item has also been added. Users of VideoScape 1.0 may remember the inconvenience of being forced to reload animations after playing them once, Now VideoScape holds on to them. The option to clear all settings, or just objects, is a nice one.
"Import Modeler Object" is another new item. While multi-tasking VideoScape with Aegis' upcoming Modeler 3-D, (an incredible object design tool I'm not allowed to discuss yet), this feature lets you import an object from Modeler to VideoScape so you can use it instantly. About VideoScape 3-D gives you the number of points available with your memory.
My 1.5 Mb 1000 says I'm allowed 1900 points. Last here is "Quit." You can probably interpret that yourself.
The newly added Display Menu lets you load your own color palette into VideoScape 3-D. It uses thirty-two colors for shading; sixty-four, if you turn on the "Extra Halfbright" selection (for those machines with the Extra Halfbright chip).
Perhaps the most important addition is "Hold and Modify," which turns on the HAM mode and lets VideoScape use all 4096 colors. The feature Aegis calls "our answer to ray-tracing" is WONDERFUL! As you might expect, it takes a long time and a bit more memory to generate a HAM frame, but the effect is wonderful. A demo showing off the new effects involves a gold-plated mask rotating over a checkerboard, with a transparent reflection on it. Each frame, one of which is shown here, took four minutes to generate on a standard
Another new menu, Extras, has a slew of new options. "Nonlinear Morph" makes the points of the morphing object accelerate at the start of the morph, then deccelerate into their new positions. "Nonlinear Zoom" does the same thing with the camera zoom function. Selecting "Black Outlines" outlines all the polygons in your object in black, defining the separations more clearly. "Crossed Dots" makes single point polygons into small plus signs for example, the adjustment makes stars more visible in higher resolutions. "No Dithering" is mainly for use when recording the Amiga's composite video
output because the dithering used in non-HAM solid scenes tends to flicker in some cases. The "Use Z Buffer" option changes the way VideoScape handles its hidden surface removal. Using this feature requires a lot of memory, as much as
1. 2Mb for a 704 x 440 scene!
Finally, the Record Menu has been enhanced. As before, "Bogin and End ANIM Recording" items are here, allowing you to save short animations to disk or RAM for later recording or showing on a standard VCR. The technique for saving has been improved: a VideoScape 2.0 animation takes up half as much space as a 1.0 animation. These new ANIM files can be played back with version 4.0 of ShowANIM or 4.2 of PlayANIM.
ShowANIM is included on the disk.
The "Begin and End IFF Save" items are new, and could come in handy.
This feature saves each frame to disk as a numbered IFF picture. The pictures then can be loaded into any IFF program, such as DeluxePaint, brushed up, loaded back into VideoScape, and recorded as an ANIM file.
The last item here isn't exactly new, it's just easier to find, "Send To Serial Port" allows animations to be sent into special drivers to run professional video editing consoles.
(continued) EGG (Easy Geometry Generator) Included on the VideoScape disk are three programs to help you design your objects. Unfortunately, none of them are very user-friendly; they are often downright impossible! The first of these programs, the Easy Geometry Generator (EGG), is probably the most useful.
EGG presents the user with a dull text screen displaying a list of nine different "Geometry Types," including boxes, spheres, cones, and cylinders.
After you select your type, you must answer a series of questions regarding the dimensions of your selection.
Since meters are VideoScape's main unit of measurement, they are the ones you must use. EGG then generates an object to your specs and saves it to your disk. Most users will also find a purpose for the spherical starfield and ring of distant mountain geometry types, which are now available here.
One of EGG's main problems is that you don't get to see what it is generating. Running an object through EGG a few times before you get it the way you want it is not uncommon. Also, it seems to want to write the file only into the GEO directory on your VideoScape disk. As hard as I tried, I couldn't change directories. Luckily, Aegis added the option to abort EGG by hitting "0" at the main prompt. In the previous version, you had to enter some data, then tell it not to save before you could exit. It's not a big improvement, but it's better than nothing, 1 guess.
OCT (Object Composition Tool) OCT is used to make color changes to objects, resize them, glue them together, and rotate them. Another dull text screen asks for the name of an object on your disk. After you load the object, you must answer a series of questions: if and how the object should be transformed, scaling factors, color changes, and the name of the new file. OCT also allows you to convert old format VideoScape objects into new Binary Format. While Binary Format makes objects load noticeably faster into VideoScape, they can't be edited in this format. Therefore, save your finished
object as a Binary file to speed up the load time.
OCT also suffers from EGG's problem you don't get to see what you're working on! Putting wings on an airplane, for example, is hard when you can only guess the locations!
D3D (Designer 3-D) This program, formerly known as "ROT" (a public domain object generator by Colin French), is supposed to allow you to build your object by drawing it on the screen. As you choose each point, you must move the point and polygon number registers, This process becomes confusing very quickly. Fortunately, Aegis Modeler 3- D, which 1 mentioned earlier, will do all the things that EGG, OCT and D3D do, but it'll do them right!
Until Modeler becomes available, the best method is to enter the data by hand. This means designing the object on a piece of graph paper, figuring out the coordinates of each point, and then typing them into a text file. It really isn't as difficult as it might sound. In fact, Allen does most of his objects in this way. A beautiful Lotus automobile included on the disk is made of 554 points and 439 polygons!
Now Colors and Mora Besides the Halfbright and HAM modes, a few new colors have been added to the fixed palette. Two shades each of purple and cyan are now available, and any colors can be glossy, matte, or luminous. A new transparent feature is also available; it checkerboards the background color and the color of your object. Other new colors create bright, shadow, or chrome effects. The possibilities are amazing!
Fln Overview VideoScape 3-D 2.0 is an excellent program, but like everything else, there are a couple of problems fortunately, they aren't major ones, ANIM files made with the Extra Halfbright feature can't be played on a non-halfbright machine. Also, you can't use VideoScape with less than 1 Mb of memory. Even though it is possible to run on 512K, the program really can't operate at its full power.
Movement in VideoScape is defined by traditional X, Y, and Z (width, height, and depth), and Heading, Pitch, and Bank (rotations around X, Y, and Z axis). While these terms are certainly familiar to pilots and mathematicians, many people will find them hard to follow. Aegis included a cardboard device for the user to put together that illustrates these principles nicely, and makes learning easier.
The manual explains features well, with plenty of examples. The best way to learn, however, is to experiment. VideoScape is a lot of fun to work with once you get the hang of it, and I fully recommend it. With Allen constantly working on new features requested by users, VideoScape will always be a stop ahead of the rest.
Many VideoScape users send copies of their animations to Aegis. The quality of material is impressing even Aegis, who will soon hold their second desktop video contest. My favorite was a very detailed space saga created for a child's birthday party. The program lasted several minutes and looked professional. I can hardly wait to see what people do with 2.0!
The VideoScape 3-D 2.0 package includes all the things already mentioned, plus two disks packed with objects, backgrounds, foregrounds, and sample animations. Aegis will sell 2.0 for SI 99.95, and it should be available by the time you read this. Registered owners of version 1.0 will be notified about an update.
• AC- New Cli Window
l) by Rich Falconburg SC The Command Line A Beginner’s Guide to
the Amiga CLI Getting Started Without question, the Amiga
stands alone in flexibility and power, at a price the ordinary
user can afford.
Unfortunately, many of the real strengths of this wonder-machine go unnoticed or under-utilized. Even experienced users often overlook some of the flexibility and power of its very capable Operating System. This column will attempt to clear the fog around AmigaDOS and its sidekick, the Command Line Interface (CLI), and demonstrate various methods to make your time at the keyboard more productive. To insure that everyone has a common knowledge base and will understand the terms and concepts I use, I'll start at the beginner level and work up.
From here we'll graduate to subjects and methods even experienced users wili find helpful. I intend to cover each command in detail, grouped in a logical order of use, and investigate the various options of each. The discussion will be tutorial in nature and, for some of the more knowledgeable users, tedious at times. I will assume, however, most readers are familiar with the Workbench, and that they have have given the Introduction to Amiga at least a cursory glance.
For the tutorial's duration on the AmigaDOS, I will use the basic Workbench boot disk as shipped with the computer. All examples are shown with the input from the user underlined and, unless otherwise stated, terminated by pressing the RETURN key. AmigaDOS commands will be printed in all capital letters.
Along the way, I'll interject various methods to simplify operations and I'll make suggestions for alternative approaches. Ensuing articles will examine different aspects of AmigaDOS including but not limited to:
• Manipulating Flies and File Contents
• Devices, Assignments, and Logical names
• Mountllst and Editors
• Startup-Sequence and Batch Operations
• Public Domain Commands and CLI alternatives
• AmigaDOS Replacement Project (ARP commands)
• Hard Disk Organization The order may change, and more topics
are sure to be added. This gives you some idea of the type of
information that will be covered. In this installment, we'll
begin the AmigaDOS Command tutorial with a discussion of the
directory structure, and cover the various aspects of
manipulating and navigating directories. However, the first
order of business is to establish a window to the wonderful
world of CLI.
Getting Started The process for opening a CLI window using a standard Workbench disk is somewhat different between the A500 A2000 machines and the older A1000 model. Double-click on the Workbench disk icon. For the A500 A2000 users, one of the icons displayed in the Workbench window is labeled "CLI."
(continued) The A1000 users must first set a switch in Preferences. Double-click on the Preferences icon to bring up the Preferences screen. In the lower left- hand corner of the Preferences display, just above the color sliders, is a gadget labeled CLI. Place the pointer in the ON box and click. Save the preferences and exit. Double-click on the System drawer and another window will open to reveal several icons, one of which will be labeled CLI. This is our real starting point.
Now, regardless of system, doubleclick on the CLI icon and another window will open (Refer to Figure 1).
This is known as a console window.
It might be preferable to re-size the window to full screen. This kind of window is capable of displaying text only. The environment is known as the CLI. The 1 that is displayed is the CLI prompt. The number is provided by AmigaDOS to indicate which CLI you are presently using.
Remember, this is a multi-tasking machine and it's possible to open as many CLI windows as memory allows.
A nice thought, but it's rarely necessary to have more than two or three open at once.
The CLI environment allows us to enter commands to cause the computer to perform any number of operations.
These operations vary in nature, from examining the contents of a disk, to controlling over-all system operation.
At this level the user is provided direct and immediate communication with the computer.
Some simple editing is provided in the
CLI. To delete the last character entered prior to pressing the
RETURN key, use the BACKSPACE key. If you need to delete the
entire line, press the control key, and holding it down,
press the X key. No, it's not possible to edit the line
using the cursor keys; and the delete key prints only a
checkered box. But all is not lost.
Several enterprising programmers have written programs such as CLE, MyCLi, ConMan, and others, that help correct these deficiencies. I'll be covering these and several other Public Domain programs in future editions of this column.
The Information ShulTIc Before we get in too deep, a short description of the Amiga's disk file system is in order. The Amiga is equipped with one internal disk drive.
This is a physical device referred to as DFO:. Although AmigaDOS is aware of a device called DFO, it doesn't really use that designation for directory operations. To make everything easier, AmigaDOS uses the Volume Label (disk name). This approach greatly simplifies single disk operation.
Each drive is seen as a generic Input Output device.
By this, I mean AmigaDOS sees the physical device (DFO, DF1, DHO, etc.) as the vehicle for the information, something like an "In" or "Out" basket. This means the same device may be used by different Volumes, and AmigaDOS will keep track of each. You have probably experienced this feature several times already, especially if you have only the one disk drive. When you issue a command or otherwise attempt to access the Workbench disk without the disk in the drive, you often see a requestor asking you to "Insert Volume Workbench in any drive." "Any drive" means just that. If you pop the
Workbench disk in DF3: (assuming you have that many), AmigaDOS will happily accept it and continue. (But you may have to click Retry first. The Workbench disk is unique.) The system found the disk by looking for the Volume Label. I'll explain this in greater detail when we get to assignments and logical operations.
AmigaDOS provides for a layered directory structure, sometimes called hierarchical, in which data are divided and sub-divided into organized groups (refer to the diagram in Figure 2). The top layer is called the ROOT directory.
When we look at the device using the designation DF0: or the Volume Label, this is the directory we see.
The next row of directories represents the division of the ROOT directory into the organized groups mentioned, each separate from the others. Several of these are sub-divided further; this chain can continue much farther than most users will need. (For the sake of brevity, only the directory names and a few files are shown. In reality, there are a number of files contained in each directory).
To supply AmigaDOS with a beginning reference point, certain things are assumed by the system. These assumptions are called defaults, the values AmigaDOS will use until you inform it to use something different.
The default directory is set to the boot volume, as in WORKBENCH 1.2:. AmigaDOS file names are quite flexible and allow up to 30 characters.
All special characters space, etc.) may be used with few limitations except for the slash ( ) and the colon (:). (I'll explain why later.) Using special characters requires the entire specification be placed between quotes.
For example, you'll often see names with spaces in them, such as: Read Me For AmigaDOS to recognize this name it must be entered as: ¦Read Me" If the device or volume name is included, it must be inside the quotes as well. To use quotes ("") in the filename, precede them with an asterisk (*). The asterisk must be entered twice (**) for AmigaDOS to accept it. Now, grab your keyboard and let's take a tour.
Directories Click inside the console window to activate it. You'll find that this particular step is easily overlooked.
As with Workbench operations, the window must be active to accept input. Let's verify where we are first.
This is done using the CD command with no parameters. Enter CD and press RETURN. You should see the following: 1 CD Workbench 1.2: 1 CD means Current Directory. Entered by itself, it will always display the directory your default is currently set to. The colon indicates that this is the ROOT directory and is appended to the Volume Label. Because the colon is used by AmigaDOS this way, it cannot be used in file names. Generally, the Volume Label and the root directory name are always one and the same. Here, I interject the first of Rich's Commandments of CLI: Know Thy Default!
Get in the habit of checking or confirming your present default.
Believe me, if you do, you may be spared the "agony of delete" from overwritten files or worse, deleting the contents of an entire directory.
With the power of AmigaDOS comes greater responsibility. Some wise person once said that "a computer is a device designed to allow humans to make an ever increasing number of mistakes and to make them faster."
Having been a victim of this, I wholeheartedly agree. I hear one of the experienced users mumbling something about Public Domain commands that display the default for you all the time. Agreed, but before we get to what AmigaDOS should be, I want to cover what AmigaDOS is.
Besides, not all the P. D. commands always work properly. (1 use the improved PROMPT command provided by ARP, but that's a discussion for another time.)
To use CD to navigate the directory structure we need to determine what is on the disk. Do this with the command DIR, For example: 1 DIR c (air) System (dir) I (dir) devs (dr) s (dir) fonts (dir) libs (dir) Utilities (dir) .Info CLI CU.info Clock Clock.lnfo Dlsk.lnfo Preferences . Preferences.info This, or something like it, is what the Workbench disk ROOT directory will resemble. Notice how everything is neatly separated for us. At the top of the list we see several entries followed by the (dir) notation. This indicates a sub-directory. In this case, the directories listed are
sub-directories of the ROOT directory. By "sub" I mean it's located "under" the current directory.
Let's look at the contents of the devs directory. There are two ways to do this. If we don't want to change our default, it's possible to provide the DIR command with the name of the directory. For example: 1 DIR devs keymaps (dir) printers (dir) clipboards (dir) clipboard.device mountllst narrator.device paraltel.device printer.device serial.device system-configuration This operation can be taken even farther. To look at a specific subdirectory, all you have to do is separate the names with a slash ( ).
Now you see why that character cannot be used in filenames. Enter the following to look at the printers directory: 1 DIR devs printers AlphaproJOl Brother_HR-15XL CBM_MPS1000 Epson Epson_JX-8G generic HP LaserJet HP_LaserJet_PLUS Imagewriterll Okidata_292 OkidataJ?2 Oklmate_20 SG10 StarNXlO This directory "stacking" can be used with a number of commands. The term used to describe this "directory directory directory,.." list is path, It's also the command PATH, used by AmigaDOS to define a specific directory structure. Every time you enter a command, AmigaDOS first looks in the current
default directory and then in the C directory for a file by that name. If it's not found, the message "Unknown command" is returned. By using the PATH command, you may define other directory structures for AmigaDOS to search.
For example, the standard startup- sequence file establishes the paths for finding the SAY, DiskCopy, Notepad, Calculator and other commands.
An Easier Way Entering the entire path specification every time we need to do something in a directory soon becomes monotonous. Fortunately, the CD command makes life easier. For example, let's change our default to the printers directory listed above like this: 1 CD devs prlnters 1 CD Workbench 1.2 :devs printers 1 The second CD was used to confirm our new default. Now just enter DIR and you will see a listing the same as above. Figure 3 may help clear up what we just did. As shown, we moved down the path to reside in the printer's sub-directory. Now, to see the contents of the ROOT
directory, we must use a path specification.
There are several ways to do this (each of the following is equivalent): l DIR dfO: ~absolute (device) 1 DIR : ~ absolute (for ROOT of default Volume) 1 DIR II relative As you can see, the DIR command is quite flexible. Each of these examples will produce the same listing.
Absolute means to define the complete path specification, starting at the top of the hierarchy. The relative specification may be new to you. It tells the system you are using the current default directory as a reference and that you want to display the directory that is two steps above it. If you said, "I'll bet each of those methods could also be used with the CD command," give yourself a cookie and go to the head of the class. It's often convenient to jump from one sub-directory to another without entering the entire path. For example, to CD to the keymaps directory from the printers

If you check the directory of volume Letters, you'll see the two new directories created, You could also CD to the volume or directory you want to create a new directory in, then enter MAKEDIR and the directory name. Now, when using your text editor or word processor, specify the directory by preceding the file name with the name of a directory and the separating slash. For example: L0fters:Famlly Tommy (The Volume is unnecessary if that is your default.)

This is the "opt i" or interactive option. The following commands may be used after you enter DIR opt i and the question mark is displayed.
Organizing a Disk Now that we've learned about the directory structure and how to get around in it, let's see how to use a command to set up our own directories. For instance, you soon find that saving every letter you type in one directory becomes difficult to manage.
How do we organize our data files?
With directories of course! AmigaDOS provides us with a convenient command for creating our own directories.
Guess which one? If you said MAKEDIR, pat yourself on the back.
Here's an example of how we use it.
It would be nice to keep the letters we send to our friends and relatives separate from official correspondence.
The data disk has been formatted with I hope this introduction to AmigaDOS directories has helped you. Next issue, we'll learn how to use the LIST command to display various attributes about our files, as well as several commands used to manipulate files and directories.

The Latest Amazing Amiga Developments by Michael T. Cabral Into the Wild, Blue Yonder!
Move over, Chuck Yeager. Thanks to Jet, the latest from subLOGIC Corporation, Amiga owners can now take control of our armed forces' hottest flying machines. The FT6 Fighting Falcon tactical craft and the Navy's F- 18 Hornet multi-role fighter are at your disposal it's up to you to put them to work.
Jet offers a number of game options and flight features. You can hone your flying skills in the free flight mode, or head straight into the real thing: honest-to-goodness air battle.
Various land sea target strike scenarios and nasty, computer-guided MiG- 21 and MiG-23 fighters await cocky Amiga aces. A full-screen "Heads-Up" display of both your instrument panel and your environment gives you a fighting chance. Also on your side, you've got search radar, automatic target tracking, an arsenal of combat ordnance, and an ejection seat ... just in case.
Jet from SubLogic Jet also gives you a number of different vantage points. 3-D windows let you eye the scene from the cockpit, spot plane, or tower. If you really want to follow through on your actions, a new feature lets you follow your missiles right smack to the point of Kaboom! impact. If you prefer a safer outlook, check the full screen or map viewpoints.
Like its predecessor, subLOGIC's Flight Simulator, Jet allows you to take personal battles to the air. A serial port hook-up to a second Amiga lets you battle a fellow pilot head-to-head until one of you goes tail-spinning into oblivion. For the more relaxed moments, there is plenty of scenery to take in, including support of the subLOGIC Scenery Disks. So, if you think you can cut it as a fighter pilot, or even if you just want to go out for a Sunday fly, jump into the cockpit of subLOGIC's Jet.

of CCAS Crowded Computer Area Syndrome.
Alongside your Amiga console, you've got a mouse, a 20Mb hard drive, an external 3.5 inch disk drive, scattered manuals, and a snarl of cables. Not only do you have to put up with an overcrowded desk, but there is also the danger of blocking the ventilation on your machine and hard drive.
Just when you thought you were doomed to this less-than-efficient environment, along comes the Amiga 500 Command Center from KETEK, Inc. to save the day ... and a whole lot of space and frustration.
For easy access, the Command Center allows you to sit either two 3.5 inch drives or one 3.5 inch and a 20 or (continued) Slipped Disk, Inc. 31044 John R Madison Heights, MI 48071 EA's IntelliType 30Mb hard drive directly above and behind your keyboard. Not only are the drives now out of your way, but they are also better protected the Command Center includes a built-in cooling fan. Other useful features of the Command Center include surge supression, EMI noise filter, and a five outlet power strip which puts switches for each of your components at your fingertips. And if a well-dressed
computer desk is your thing, the Command Center is color coordinated to match your Amiga 500.
Accessories are available to complement the Command Center and complete your workstation. Add a 20 or 30Mb hard disk, a one or two Mb internal RAM upgrade, a heavy-duty replacement power supply, joystick extension cables, a dust cover for your entire unit, or a tilt swivel monitor stand. If you're frustrated by the look and inefficiency of your work area, let the Amiga 500 Command Center clean up your act.
Big Bucks!
Now that I've got your attention, I can tell you that big bucks is really what Lottery Magic from Slipped Disk, Inc. is all about. The program calculates and picks lottery numbers based on past results. You configure the program to fit your state’s individual lottery, and Lottery Magic flashes the dream-deflating odds. 1 set up a file for the "pick six of thirty-six" lottery I play twice a week, but I still can't understand why I haven't hit the big one my odds are a mere 1,947,979 to one!
Lottery Magic supports three and fourdigit daily lotteries, and the multimillion dollar weeklies. You simply enter the numbers as they come up, and the program takes over. The number generator evaluates the results and comes up with a wallet-wrecking number of different ways to play.
You can play the "hot" numbers the most common or the "cold" numbers the least common. If you want to get even more scientific, the generator notes the numbers that deviate the most and least from the norm. For good ol' fashioned players who rely solely on luck, the generator spits a random number and a mysterious "magic" combination. Lottery Magic also offers "systems" that wheel the various number groups to produce a set of related combinations you might want to try. How can you miss?

(800) 6264582 Just Your Type If you've ever taken a typing
course, you know just how boring and repetitive the drills
can be. It always seemed fruitless to type endless rows of
"fjfjfjfjfjfjfj" Electronic Arts' new IntelliType typing
tutor takes a shot at ending this drowsiness once and for
all. The program combines an adventure story with
artificial intelligence to teach lively typing in one
EA's philosophy is that technology is worthless if users don't finish the lessons. Enter the adventure, which the press release interestingly describes as "a mixture of Soap (the television show) and a James Bond film." As you leam to type, you hang with Ted and Laura through car chases, Bondlike stunts, and precarious meetings within foreign spies. A dash of wit and a pinch of sensuality put boredom into its own deep sleep.
The adventure is only part of the package remember, your goal is to be an error-free blur at the keyboard.
Unfortunately, practice is what makes perfect and drills have to figure in somewhere. You choose whether to emphasize speed, accuracy, or both, and IntelliType suggests drills based upon an analysis of your strengths and weaknesses.
To make things easy on your harried gambler's mind, Lottery Magic develops graphs of much of the information. A data disk of results for each state will also soon be available from Slipped Disk, Inc. Lotteries are always long shots, but I, for one, will try anything to up my chances.
The artificial intelligence of IntelliTypc (hence the title) allows the program to focus on drilling. 27 specific types of errors in nine categories are watched closely ... and specific is not the word.
Errors related to dyslexia, doubling, high keystroke speed variance, transposition errors within or between hands, and even hitting the wrong shift key are all picked up and analyzed.
The analysis also deals in depth. Bar graphs reveal accuracy, speed, and error types and can be expanded to elaborate on each individual error type. An Accuracy Analysis Window presents percentages of near mis- strokes, far misstrokes, and latency.
Who says typing has to bo boring?
IntelliType S49.95 Just Your Type, Too!
The Software Toolworks has also joined the fray for control at the keyboard with its own typing tutor.
Mavis Beacon Teaches Typing. The concept is familiar take the boredom and useless drill work out of learning to type.
In Mavis Beacon, we have a bit more of the classroom atmosphere than IntelliType, with a positive twist.
Stepping away from statistics, this program follows the old school of learning there is no better teacher than a teacher at your side. Mavis Beacon is a typing guru who explains your errors in conversational form.
She even throws in a few jokes, historical quotes, and facts from the Guiness World Book of Records to stave off boredom.
Like IntelliType, Mavis Beacon also uses artificial intelligence to get the most out of lessons. 2-D and 3-D graphics and a pair of "Guide Hands" give you a visual display of perfect technique. Color graphs track your progress, and typing games such as the arcade-like "Road Racer" and the musical 'Tempo Typing" help crack down on boredom.
Like any good teacher, Mavis Beacon shows how your typing experience fits into the real world. A "Resume Writer" program is included, and you can even get a jump on the actual tests used by employment agencies. Overall, Mavis Beacon offers back-to-basics instruction with a flavor that still conquers boredom.
The Software Toolworks Distributed by Electronic Arts 1820 Gateway Drive: San Mateo, CA 94404 Come Out Of Your Shell As A Programmer The wall that stands between the user and the power of his computer is the interface. A programmer should have easy, intuitive access to the operating system, thus providing a cozy programming environment. Unfortunately, the wall between the programmer and the computer too often seems to be one thousand feet tall and made of iron. The ingenious answer to simplifying the interface has been the programmer's "shell." The latest entry in this market is Tshell
from Metran Technology.
Tshell provides an advanced, but nicely simplified programming environment useful in software development or any other work that begs for full control of AmigaDOS. As a clone of the famed UNIX shells, Tshell acts as an "interpreted programming language," according to reps at Metran Technology.

earlier installments of AmigaTrix (in Episode One, we learned
that Mavis had accidentally spilled nuclear waste into the

AmigaTrix III A series devoted to making life with the Amiga cheaper, easier, and more fun.
By Warren Block Anyway, all the articles in this series are devoted to making life with the Amiga cheaper, easier, and more fun.
Since the hints presented here are completely without pattern, it will be left up to the reader to assign some order (or indeed, some meaning) to them. Note the opinions expressed here are my own, and not those of Amazing Computing.
The Evils Of Copy Protection Some software suppliers have had pity on Amiga owners. Rather than copy- protect their software with a DOS- based scheme, suppliers used an innocent-looking little hardware device called a "dongle," How thoughtful of them. These things usually plug into the second joystick port, and are just small enough to lose easily.
The solution to this problem is to travel down to the nearest sewing goods or department store and pick up a yard or so of half-inch wide stick-on Velcro (get both hook and loop types, or you'll get very frustrated). Cut a three-inch piece of the loop type and stick it onto the top of your computer or monitor in a readily accessible area. By placing strips of the hook-type material onto the dongles, you can stick them in place on your computer where they won't get lost. Marking both the dongles and their associated disks with dots of paint or colored markers will make them immediately
Just to keep the Velcro people happy, I should also mention all of the other fantastic possibilities this stuff has.
Stick it on the back of a calculator and hang it from the side of your monitor (despite software calculators and multi-tasking and all that hoo-ha, a real calculator is still handier); use it to route all the cables coming out of the back of the computer; stick long-haired hampsters to the ceiling with it. No, not really just kidding! Heh, heh.
Of course, the best way to avoid dongle troubles is to simply avoid buying software that uses this copyprotection method in the first place.
Fast Copies It can take an amazingly long time for the Amiga to print a page-sized picture. Multiple copies take just as long as the first one. But a public domain program called CMD (written by Carolyn Scheppner, one of Commodore's resident geniuses), trims the time down to a bare minimum.
CMD redirects into a file what normally would be printer output.
Simple enough. You "print" the picture; all of the printer commands and data go into a file. Afterwards, just Copy the file to the PAR: device.
Surprise! The printer rips off a print of the picture in record time, since it need not wait for the Amiga to generate and print every line, combined with the attendant slowness of the of printer device. (My Canon PJ- 1080A took seven minutes to print a picture directly from Aegis Images.)
Once the data had been captured in a file, however, the task was completed in only six minutes. Times will vary depending on the printer and the graphic image, of course.
Note: when capturing a picture with CMD, be sure to use the "-s" flag.
As the first part of a printout, a reset code is sent to the printer. When this code is received, the printer pauses long enough to lose a few of the following data bytes, resulting in a garbled picture. With the flag, CMD simply discards ("skips") the reset code, so it isn't included in the file.
For example: Run CMD -s parallel ram:plcture.prt redirects the output into the file called "picture.prt" in the RAM: device.
This trick also works with text to be printed, although it may not improve printing time, unless the program takes a long time to format output. If you wish to edit the output or import it into another program, it works very well.
Capturing text output this way usually produces a large and unwieldy file.
Among its many shortcomings, ED (the AmigaDOS screen editor) has problems working with such files.
Aedit (from DRM Programs, 1329 Arthur Avenue, Las Vegas, NV 89101, 702-457-9489) works well with huge files, and makes ED look like what it really is: slow and wimpy. See my review of Aedit in Volume 2, Number 11 of Amazing Computing for more details.
Rodent Revulsion In a lot of situations, the mouse just makes things difficult. (Like in the database program where you have to click on a requester after entering every record.) Moving your hands from the keyboard to the mouse slows things down. However, in many such programs, the mouse pointer doesn't need to move just click the Select button. The Amiga's been out long enough for early buyers to forget you can simulate the mouse with the keyboard. Press the left-side Alt and Amiga keys at the same time, instead of reaching for the repetitious rodent.
Some programs shut off the mouse pointer to get it out of the way, usually after some mouse move has been made. You could press Select or the left-Alt and Amiga keys, but in a word processor, that might move your cursor to the wrong spot. Pressing the Menu button or the right-Alt and Amiga keys shuts off the pointer without changing what you're doing in such situations.
Creature Comforts When you sit down at the keyboard, you're likely to be there for at least an hour. Many people complain that looking at any monitor screen (even those of expensive, super-sharp RGB monitors) for that length of time causes their eyes to hurt. Coincidentally, these same people tend to be the ones who wipe the dust off their screens once a year. Dust is attracted to video screens like moths are attracted to porch lights, and it causes the displayed image to become blurry, which in turn causes severe eye fatigue.
Don't get the idea I'm advocating attacking your monitor w'ith a spray cleaner; just use a dry, soft, clean cloth. If you really must have a liquid, use plain water. Of course, your monitor should be off at such times. The "anti-static" sprays and cleaning supplies sold for this purpose are usually unnecessary and expensive.
Not only can dust affect the sharpness of your screen; airborne dust and smoke particles grind between disk media and the heads every time you use them. With furnaces running in the wnnter, heavy deposits can accumulate in a short time. The easiest way to protect your investment is to prevent dust from accumulating around your computer in the first place. When you clean the screen as suggested above, wipe the dust off the top and sides of the monitor, the exposed top of the computer and any external disk drives, and the tabletop surrounding it. Don't leave disks laying out in the dusty air;
keep them in storage containers. A towel can be used to cover the mouse and internal and external disk drives at the same time. Another can be used for a printer. Or you can pay $ 20-530 for vinyl anti-static dust covers that serve the same purpose.
When you are ready to use the computer, remove the covers and set them somewhere out of the way NOT on top of your monitor. The covers can trap unwanted heat in the monitor.
Other factors affect your comfort, too.
Location and height of the keyboard can be very important, although these factors are much easier to adjust on the A1000 and A2000 than the A500.

After I had my Amiga for about a year, it seemed like a good idea to moderately increase speed by replacing the 68000 processor with a 68010.
231 Since then, 1 have been forced to continuously remove and replace the 68010 due to software incompatibilities. Sure, there are patches like DeciGel that allow some programs to run, but others simply refuse to work.
Some situations were nearly as bad.
True BASIC, for example, actually ran slower with the 68010 and DeciGel installed. Some people believe that patching the object code of the program in question is a simple solution, but relatively few Amiga owners have the technical ability needed to do so.
The results from running several benchmarks, like the Sieve (in Ami- gaBASIC and TDI Modula-2), with the new 68010 were less than encouraging, too: in every case of an improvement, the increase in speed was less-than- impressive 3% .
If you absolutely must have a 68010, be aware that you will have to deal with these problems. Removal of the 68000 is not a job for the inexperienced, cither I've seen too many mangled chip pins and people with neat rows of holes punched in their thumbs to recommend the procedure to novices. Once you've fought your way past all the screws and RF shielding and actually removed the 68000, be sure to put it in a piece of conductive foam in a safe place you'll most likely need it again.
For most people, a 3% increase in speed just isn't worth the hassle of fighting with the 68010.
Labeling Things Dot-matrix printers are popular, and with good reason. They are versatile enough to print both graphics and text and can use various preprinted forms, even print mailing and disk labels, Unfortunately, printed output can suffer when printing graphics and labels, usually from slippage in the tractor feed gearing. The result can be a graphic dump with white lines running through it, or jagged, misaligned characters, Then there are those printers which have tractors that can't be positioned close enough to engage the schnybblcs (that's what those tear-off pinfeed rows are
called) on both sides of a label stack. When labels are pulled by only one tractor, the feed is often crooked. Sometimes they get off-track enough for a label to peel off the backing sheet and stick to the platen.
Unless you like to disassemble consumer electronics items with lots of small screws, springs, and unnamcablc whatzits, this is not something you want to happen to your printer. (If the unthinkable should happen, dissassemble the printer and remove the platen. Then you can use isopropyl alcohol to clean the sticky gunk off.)
Surprisingly, both problems can often be corrected by the same adjustment.
Just load the labels (or paper for a graphics dump) and turn on the friction feed on the printer. On most modem dot-matrix printers, the tractors will still pull when the friction mode is on. The extra force will help keep slack out of the gearing, making for unmarred graphics dumps. It will also keep labels feeding straight, because they won't be pulled (or pushed, depending on your printer) on only one side.
Sort Of Everyone occasionally needs a printed disk directory. To make things easy to find, a sorted listing is best. With only the tools provided by an ordinary Workbench disk, this is an easy task.
First, CD to whatever directory you wish to print out. Then use output redirection to send the output of the (continued, on page 40) ULTIMATE MILITARY SIMULATOR Intergalactic Development Incorporated RainbmJ and Rainbird Lo&o arc registered trademarks of British Telecommunications PLC Telecom Soft, P.O. Box 2227, Menlo Park, California 94026.
(continued from page 38) List command to a file in RAM:, like so: List RAMdemp Load the file into ED (or Aedit but I did say you could do all this with an ordinary Workbench disk) and delete the first and last lines, which show information about the listing rather than actual directory entries. Then sort the temporary file and print it at the same time with: Sort RAM:temp to PRT: You can use SER: or PAR: instead of PRT:, or a disk filename to save the sorted listing for later use.
Note that the Dir command won't work for this purpose, for reasons not immediately obvious to most people.
Try it out to see why.
Another use of the Sort command is to create a miniature database. By using one-line entries, and putting the sort field at the front (or using Sort's "colstart" flag) is easy. For example, a group of names entered in the following format would be sorted by name: Jones, Bill, 888 Eigth, Sippleville, NC, 88088 (808) 808-1234 while a file in the format
(808) 808-1234, Jones, Bill, 888 Eigth, Sippleville, NC 88088
would be sorted by phone number.
Sort sorts by ASCII value, so some entries may not be in the obviously correct place, but they will usually be close enough to make it simple to correct them with a text editor, The biggest problem with using Sort this way is that everything must be on one line. Since some text editors have line length limits of 512 characters (Aedit does, and 1 believe TxEd does also).
It's not such a bad problem after all.
Limiting Factors An A1010 external 3.5-inch disk drive is an excellent investment for A500 and A1000 owners. But it was designed with the A1000 and its front- facing internal drive in mind, making the drive a bit inflexible. The cable is not quite long enough to permit easy selection of the drive's location; for A500 owners with their side-facing internal drives, the situation is even worse. A longer cable would be nice.
But so far none have emerged from the factory this way.
Fortunately, Jim Black of BCD (P.O. Box 1224, Bartlesville, OK 74005, 918- 336-1784) has two-foot drive extension cables for only $ 13 (plus $ 2 shipping), which eliminate the need to stand on your head to load disks into your external drive. A number of other hard-to-find accessories are also available from BCD, including power supplies for extra external drives and custom monitor cables. If you want to wire things up yourself (What could be more fun than wiring a cable that, if done incorrectly, could destroy your computer?), the oddball connectors may be ordered alone, too.
Bandwidth Considerations On-line networks like PeopleLink and CompuServe have made access to information and new public domain software much easier for Amiga users, but before you download that program, consider the cost. Some Amiga programs (especially ANIM format animations) can take two or three hours to download. At roughly five dollars per hour, you've spent fifteen bucks for one program.
Or you can order a disk full of public domain software by mail, and get a dozen programs or so for six dollars (assuming, of course, that you already subscribe to Amazing Computing if you don't, you'll pay an extra dollar per disk). You will have to wait a bit ionger to receive the disk, but it will contain much more software.
You may need a program urgently, and in that situation, downloading can be a reasonable alternative. If your need is less pressing, use the networks for information, and pay less for more software by ordering public domain disks. You'll find a complete listing of more than 130 (!) Public domain disks in this issue.
Evolution At Work My Startup-Sequence file is constantly modified. Almost daily, new commands are added, others deleted, still others modified. But a few remain in place constantly. 1 may change their parameters a bit now and then, but the programs themselves arc always there. These lean and hardy survivors have come up against contenders many times, but they have always prevailed (so far). These "fittest" programs have a lot in common.
One simple, but necessary quality, is that the program in question not be copy-protectcd in any way. This includes those programs that force me to hunt down a manual and search for a keyword, as well as dongle-protected programs like those mentioned above.
The delay just isn't worth it. Fortunately, really good programs are never copy protected.
Traits other than lack of copy protection play just as important a part in a utility program's survival. The program shouldn't adversely affect system performance. If things slow down, or it gets in the way, it's history. Programs that want input during a long booting process should at least be able to get it from a redirected command file (using the " " symbol); of course, a command- line option is handier. Finally, the program should disappear completely, unless I summon it somehow.
The programs that have managed to survive in my Startup-Sequence so far include: (continued on page 42) TAKE A DRIVE INTO TOMORROW Tomorrow's disk drive is here today.

Replies that do materialize are likely to be pretty strange. EXTEND An AmigaBASIC Extension by Bryan Catley Despite its ability to access operating system routines via the CALL statement, AmigaBASIC does not provide easy access to many of the Intuition routines. For example, it is very difficult, if not impossible, to access the built-in facilities for using requesters, gadgets, sub-menus, changing gadget colors, changing menu colors, changing window titles, etc. But now you can use all of these facilities, and more, with a EXTEND, a new product for AmigaBASIC users.
EXTEND is implemented with the standard LIBRARY command (which means it also has an associated ".bmap" file), is extremely easy to install, and provides users with 33 new commands with very little additional overhead! It may also be used with interpreted programs and programs to be compiled with Absoft's Basic compiler.
The Additional Commands What are these additional commands? Well, just to let you know exactly what's there, let's list all 33 of them: BUSY toggles pointer between standard and 'WAFT CHANGE changes window titles CHECK polls a series of gadgets CHECKSUB checks for sub-menu selection CLEARBUFFERclears contents of a string gadget CIOSEUB de-allocates gadget memory COMMANDKEYsets a command key sequence for a given menu Item DOS executes a valid AmigaDOS command FREEMEM de-aliocates all memory allocated via MEMORY GADBCOLORsets attributes for gadget borders GADGET places a gadget in the current

This single command will open a window with a
given title, allow you to select any path, then display the list of files, which may be scrolled up and down within that path. It is also possible to return to the parent of the current path if desired. When a file name is finally selected, it is returned to the using program, along with its full path. The file may then be processed as desired a very powerful command!
Using These Commands If you have ever used any operating system call on the Amiga, such as SetSoftStyle, Move, TextLen, etc, you already know how to use these new commands. It's that simple!
You must provide a LIBRARY statement for the EXTEND library, and a DEFINE FUNCTION statement for each command which will be used to return some value to the using program. From then on, just code the desired commands and parameters.

Dealer Inquiries Invited Amiga is a trademark of Commodore-Amiga. Inc, However, there are two things which you should be aware of. First, one mandatory command, SETWINDOW, must be used at the beginning of the program and each time the program switches windows. Secondly, some functions require a series of commands, in a specific sequence, to be accomplished successfully.
A short and simple example might be: DEFLNG a-2 LIBRARY ‘extend .library" SETWINDOW WINDOW(7) DOS SADD(*list dfl :'+CHRSC0» CLOSELiB LIBRARY CLOSE END Note the DOS command must usually be used from a program started via a CLI, and not via Workbench. This is because most AmigaDOS commands direct their output to the current CLI window, and there is no such window when a program is started via Workbench. When attempted, the result is almost always a system crash!
Distribution and Installation EXTEND is distributed on a single, non copy-protected, bootable disk. There are only two files of real interest on the disk: "extend.library" and "extend.bmap." For the most part, the rest are standard Workbench files.
In addition to the disk, the package contains some documentation (more on this later) documentation updates (if any are required), a registration card, a q & a sheet regarding potential problems the user may encounter, a license agreement (for possible distribution of developed programs, I assume), and promotional material for other products.
Installation is very simple but must be done via a CLI. If you think you would like to use this product but have not yet used a CLI, you should familiarize yourself with it first.
The documentation suggests you boot your Amiga using the EXTEND disk, then copy the extend files to the disk of your choice. Since this disk will almost always be your normal working Workbench disk, I suggest you do things the other way around: boot your machine as usual, then copy the files from the EXTEND disk to your working Workbench disk. (Remember, only work with disk copies, not the originals.) Assuming you're using a two drive system with the EXTEND disk in DF1:, you can use a command such as: COPY Dfbllbs extend ? TO DF0:libs You are now ready to start using EXTEND! However, you will
probably want to run most of the examples before you start using the new commands in your own programs. The easiest way to accomplish this is to "drag" the Examples drawer from the EXTEND disk to your AmigaBASIC disk where you may double-click the examples to run them.
All the examples run, and many contain multiple commands showing how they should be used in conjunction with each other. If you have a printer, it would be worth your white to print all 32 of them. (They average 30 to 40 lines each.)
Problem Areas Great as EXTEND is, it is not without a few problems. But if you have any programming experience at all, they should not be of serious concern to you.
One of the most obvious problems is that EXTEND is somewhat difficult to use. For example, all string parameters must be passed as addresses, making them awkward at best. (Wouldn't it be nice to just say DOS 'list dfl:"?) You should also note that commands are very sensitive regarding syntax. A missing ")", for example, will result in a system crash rather than a simple error message! (These two problems are shared with all calls to all library routines.)
WBExtras CLI WSExecute SeePicture LoadPicture UnloadPicture Lynn’s Luna SV3TEM INNOVATIONS Command sequence is also very important when several commands are required to accomplish something. For example, to display a gadget on the screen, you must first describe it in an array, the address of which is passed to the GADGET command via a basic VARPTR statement. Well, no basic statements are allowed between the VARPTR and GADTGET statements; in fact, you must use two separate statements. (It seems the VARPTR may not even be included as a parameter within the GADGET statement.)
While EXTEND is almost fully compatible with Absoft's BASIC compiler, there are differences in the way some things work. These differences are documented in the Q & A sheet and should not prove too serious; they may require two versions of the program, though. The one known incompatibility is that programs making use of sub-menus will not function correctly when compiled. Apparently, this is a problem with the compiler since AmigaBASIC does not support sub-menus, the compiler is simply not set up to handle them. The problem should be fixed in an upcoming release. Nonetheless, this restriction
is not documented.
The GETF1LES command is a handy one, but with the version of EXTEND I am using, its output is directed to the Workbench screen, making it unusable with a custom screen. (Please note that a later version of EXTEND does allow custom screens with the GETFILES command.)
All numeric parameters used with extend commands must be defined as long integers. This means that cither a DEFLNG a-z statement must be included at the start of the program (forcing all numeric variables to default to long integers), or they must have a appended to them (this also includes the commands themselves). It is no different from any standard (non-EXTEND) operating system call, but it is still a little annoying for the AmigaBASIC programmer.
As you can see, these problems are more annoying than serious. Careful coding, and learning some of the more unusual requirements, will enable you to use the EXTEND package to its full advantage, with minimal frustrations.
The Documentation EXTEND's documentation is probably its weakest area. It consists of 12 pages of reduced and copied text which is somewhat difficult to read. It is arranged with a small "Getting Started" section at the beginning, followed by a description of each command. The descriptions are (for the most part) reasonably complete, but they give very little indication of the interaction between the various commands.
You have to search through the examples then hope you can understand what is going on. As already indicated, there are also a number of things omitted.
Ideally, a tutorial section explaining how things fit together should be included. Sections covering the use of Gadgets, Sub-menus, Requesters and so on, using the given examples as a basis, would prove very useful to many potential users.
Don't be put off though. It just involves a little more effort on your part to understand things thoroughly!
Using EXTEND When reviewing a product of this type, it is somewhat difficult and time-consuming to use every command in a custom programming environment, especially when programmed examples of every command are also provided.
However, I did want to check out some of the commands in programs which use custom screens and windows. To do this, I modified some existing programs, concentrating on sub-menus, command keys, requesters, and gadgets features which use most of the commands anyway.
Sub-Menus, et al.
The first effort was directed at modifying some custom menus to use sub-menus, box (rather than complimentary) highlighting, and command keys. After I studied the examples and documentation, the changes were relatively easy to make, and the results were excellent (although I would have liked to be able to choose where the sub-menus appear, rather than accepting EXTEND's arbitrary choice).
(continued) Isn't it time you got the most from your Amiga?
Now, “WBExtras' is here and is specifically designed to enhance operation of the Amiga by the "New User" as well as the “Seasoned Programmer''.
For the Amiga User. . .
Use of New Workbench Menus, "RAM Tools" and "WBExtras" provide access to ANY Workbench Too! From the Workbench Menu and allow "Multiple Icon Selection" without the use of the "SHIFT Key". Also, "New Execution Modes" permit a "Single Loading" of Workbench Tools for Multiple Task Execution. This results in “Optomized Memory Allocation" and "Reduced Disk Thrashing". For FULL System Memory, WBExtras will "PolitelyRetire" and RELEASE ALLOCATED MEMORY WITHOUT RE-BOOT. As a BONUS, several New Workbench Tools are included (See Menu).
For the Amiga Programmer. .. WBExtras includes SOURCE CODE in "C” and "AmigaBASIC’' for Workbench Tools using a NEW Programming Technique which provides “Optomized Memory Utilization". "Inter-Program Communication'', and “Disk Access Queing".

Four commands are required to accomplish all this. SUB- COLOR defines the colors to be used when displaying the sub-menus; SUBMENU defines the actual sub-menus to be used; MAT defines main and sub-menu menu characteristics (type of highlighting, checked non-checked, mutual exclude flags, etc); and COMMANDKEY defines the "right Amiga- key key" combinations which may be used as alternates to the menus. I also made extensive use of the BUSY command, another really neat feature of EXTEND.
However, I did run into a couple of problems while doing this. First, as already mentioned, the documentation does not provide enough information. Second, EXTEND is very unforgiving of errors. Any simple syntax error will almost certainly provoke a visit from the Guru rather than a simple error message! (Note that this is true of any and all system calls, not just those for EXTEND.) Documentation omissions included: command sequencing (in this instance you must define all the basic menus first, provide a delay which allows AmigaBASIC to set them up, define the sub-menus, define the menu
characteristics, and then define the command keys), the need to provide space in the menu descriptions for the command keys, how to initialize a menu item with a check-mark, and so on. However, the results were excellent and worth the effort!
Gadgets As far as gadgets are concerned, I worked with the examples provided, setting up custom screens and windows, changing colors, etc. Alt worked well, but once again, there were a few frustrations of the type described above.
Even up the Score !!!
Gadgets are drawn as a single line box along with the associated text. You define the location and size of the gadget, with the location of its text in an array which is then passed to the GADGET command. With the present release of EXTEND, you may also choose between Boolean (Yes No) and string gadgets. Proportional gadgets (sliders) arc not yet supported. If you want "shadowed" gadgets, or gadgets with an additional outline, you must draw these extras yourself using standard AmigaBASIC commands.
Colors are set with separate commands for border and text.
Each of these commands has three parameters: foreground color, background color, and drawing mode. However, the border color command does not seem to make any obvious use of the latter two parameters.
Setting up and using these gadgets is a lot easier than doing the entire thing in AmigaBASIC! Plus, a couple of additional features (like disabling and enabling gadgets) automatically become available to you. Very useful!
Program Development and Distribution EXTEND, especially when used in conjunction with Absoft's AmigaBASIC Compiler, makes AmigaBASIC a realty viable development language. (The biggest drawback is the excessive amount of memory the final product requires.) So, if you develop a program using EXTEND which you wish to distribute, it follows that you will need to distribute EXTEND along with your program. The owners of EXTEND will allow you to do this for a one-time fee of S100 per distributed program. It is a great deal, and if you have been waiting to do some development with a product like
EXTEND, take advantage of this offer. (I feel that as EXTEND increases in popularity, the fee could increase too.)
Some Final Words When it comes to products which extend the capabilities of an existing language, the bottom line is: "Should I buy it?"
My answer is pretty straightforward: If you have been using AmigaBASIC for a white, if you are reasonably familiar with operating system calls, and if you feel you can make use of the additional facilities offered by EXTEND, buy it! I doubt you will regret it. Just be prepared to accept a few frustrations. If you do purchase it, remember to send in the registration card. By the way, there is a S5 charge for updates.

H4 lire inline I7E2 The System The documentation accompanying
the package is divided into sections describing the utilities'
functions. It is strictly a reference tool for the menu options
available in each utility. No summary of 68000 instruction
syntax or Amiga operating system interface is provided in the
documentation. Likewise, very few techniques and requirements
of assembly language programming are documented. AssemPro
assumes you already know these things or know where to get the
With these assumptions, section 1 of the documentation provides a short "guided tour." This introduction is meant to familiarize you with the AssemPro Amiga from Abacus Software is billed 'The professional assembly language development system." As the quote implies, AssemPro is more than a mere assembler. The package contains a source editor, symbolic debugger, and a tables (help) utility. The one unique feature of the package is that these development tools are integrated, allowing easy movement from one utility to another.
Although reference has been made to "utilities," it would be more accurate to describe the utilities as tasks, AssemPro is a single program that, when executed, initializes and opens a window for each task. This provides an excellent environment for program development. For the sake of clarity, I will continue to refer to these tasks as separate entities.
Multiple editor tasks can be started and data transfer between windows is supported. It should be noted that the editor's window refreshing appears a bit sluggish. In fact, Abacus' documentation warns you can hang up the system if you cause too many refreshes too quickly.
Error-search functions are provided in the editor. If the error-file switch is enabled during a compile, errors are written to a file that can be used by the editor in these functions. This development system. Although the example is a simple one, and does not provide any programming insight, it does demonstrate the interactive nature of the utilities.
Since most programs begin in an editor, this is where we will begin.
The editor is fairly simple to use and provides most of the normal operations expected from an editor.
Menu choices are provided for each of the editor's functions; many of them also have keyboard alternatives.
AnTREditcr: EtgiyAisliw.asii: feature comes in very handy if there are more than a few errors in the source code. If you know in advance there won't be many errors, you may want to turn off the error-file switch and use the correct error feature of the assembler. This feature is discussed later.
AssemPro's editor does not support macros, but a "string" of commands can be attached to each function key.
A command is comprised of a two or three letter abbreviation indicating the desired action. These commands can be appended (up to 120 gpgl characters) and assigned to one of the function keys.
Unfortunately, AssemPro docs not provide a command for every function the editor supports. Most of the commands are related to cursor movement, block operations, or search and replace.
The tables, or help, task is utilized best in the editor.
If the cursor is placed on an assembly instruction and the Help key is pressed, the tables window is brought to the foreground with an explanation of that instruction's syntax in the window. In addition to 68000 instructions, tables containing the syntax and return values of Amiga operating system calls are provided. It is possible to create your own tables to help with your programming.
After a program is written, it goes to the assembler. The assembler is a two-pass compiler and provides a number of menu options that can be (continued) used when compiling your programs.
One extremely useful option is its ability to compile from the source currently loaded in the editor. This is an excellent feature demonstrating the interactive nature of the product.
When switching back and forth from the editor to the assembler, load times are effectively eliminated.
A previously mentioned option lets you fix errors detected during assembly. Of course, not all errors can be repaired with this option. When an error is detected, the assembler stops and displays the source code in error.
If the error is not correctable, the only choice you have is to cancel the compile and return to the editor. If AssemPro can continue when you correct the error, you will be given the opportunity to retype the line. Another "plus" is the ability to apply the correction to the original file. This means you do not have to make the correction twice.
The last major utility provided with AssemPro is the debugger. The debugger, like the other utilities, is menu driven and provides a number of useful features. You can select symbolic disassembly, hex versus ASCII data display, and hex versus decimal number display. Functions are provided that let you search for data, perform calculations, define breakpoints and single-step execution.
The debugger also provides two more useful functions called the disassembler and the reassembler. These can be used to output what you see in the debugger to a file or other device, such as the printer. The difference between the disassembler and the reassembler is their output formats.
The reassembler's only purpose is to output source text that can be assembled again by the assembler. The disassembler, on the other hand, provides formatting options for the output text.
I should also mention a set of "libraries" and include files are provided that will assist in interfacing with the operating system. Complete assembly language programs can be written using the editor, assembler, debugger and libraries. Nothing else is required to make assembly programs not even a linker. The link step is done automatically by the assembler. Thus, Abacus can legitimately claim that AssemPro is "the complete assembler language development package for the Amiga."
Personal Notes Unfortunately, a "legitimate claim" does not always mean the product is perfect for everyone. It would have been unfair to you, and to Abacus, if I ignored all the strengths and goals of AssemPro just because it does not follow my personal programming practices. Therefore, 1 have separated the review of the product from my reservations. Please note that my reservations are just that MY reservations. I don't pretend to speak for every programmer, but some may find the following comments about AssemPro important.
The most significant reservation I have is, I can't link my assembly modules with object modules written in other languages. A modest statement in the documentation passes this problem off as something that can be solved by writing a conversion program. I didn't have that in mind and I will leave that to someone else.
Several programming practices of mine were rejected by the compiler, t referred to my 68000 programming manuals, and although most of these techniques were used in the programming examples, I could not find sufficient documented evidence to call them bugs. The practices in question are these:
1. With most assemblers, beginning a line with an asterisk
indicates a comment, not a label. AssemPro generates an error
if you do this.
2. You cannot put a label on a line by itself without a colon. It
can be followed by anything except emptiness.
3. Local labels must be defined with a leading backslash instead
of the customary trailing dollar sign ($ ).
(AssemPro's local labels can be more than a single digit.)
4. AssemPro does not support XREF or XDEF. This may be because
there is no need for a linker.
1 found these problems while trying to assemble one of my existing programs.
Each of these can be overcome. But it will not be a trivial task if you have a large program.
My final reservation concerns the documentation. A few pages should have been included covering the concepts of assembly programming on the Amiga. Additionally, better examples and more in depth explanations of the functions should have been included. Finally, the error message chapter could be improved tremendously. When I got error "(-
257) End of file," I looked it up in the book. It said "(-257)
End of file."
Although I do have a few reservations about AssemPro, it is a good product.
Obviously, a lot of time and thought have gone into AssemPro's development. The interactive nature of the utilities provides an excellent programming environment, and with a few minor revisions in future releases of the product, it will become an assembler for everyone.

(616) 698-0330 A programming language of power and elegance comes
into its own on the Amiga.
APL.68000 Contrary to widespread belief, APL is easy to use and highly efficient for certain kinds of programming. APL (acronym for A Programming Language) is presently seen as somewhat exotic, and is not widely used on microcomputers. It is inherently very powerful, and is superb for fast and flexible program development. My Amiga provides remarkable feature approximations usually available only on large computers. But one facility I missed was an APL language. Consequently, I was quite excited when I heard of the APL.68000 package for the Amiga, developed by MicroAPL and distributed by
the Spencer Organization.
APL.68000 exceeded my expectations.
It has virtually total compatibility with the IBM mainframe standard, VSAPL, and is a more refined implementation than other available microcomputer APL packages. System integration and operation are smoother than most new releases. Most important, they didn't cut corners on this package. This is a full APL language, with the capacity to do almost anything a mainframe version can do, albeit somewhat slower. It works fine with 512K of memory, but would really hum with a megabyte or more. Since the 68000 microprocessor can directly address far more memory, the Amiga with APL has almost unlimited

puter environment. But the develop- by Roger Nelson ment of
high quality implementations for microcomputers, especially
those with user-friendly interfaces, will probably soon
result in an increasing user base. APL originated as a
concise mathematical language. As such, it is inherently
oriented more to the expressive requirements of the human
than to the hardware needs of the computer. It is a
collection of powerful primitive functions and operators
(like the set of mathematical symbols), but is much more
extensive. These are the commands of the language,
implemented in machine code, and used by the programmer in
an immediate execution mode or in user defined functions.
The latter are the equivalent of programs, and are
interpreted, not compiled, making development and testing
simple and fast.
One feature that clearly distinguishes APL is that all data structures, scalars, vectors, and multi-dimensional arrays are treated alike and require no special declarations. Variables may be local or global, and the latter are immediately accessible to all functions or operations within the workspace.
Tables of numbers can be added or multiplied as easily as individual items; indexing and selection are accomplished with a few keystrokes, and APL requires none of the loops or counts other languages use for such operations. Manipulations for characters and numbers are completely analogous, and equally powerful. In APL, both the built-in and user- defined functions are used dynAMIGAlly, with the output from each function forming the input for the next. A single line of code may be the equivalent to a dozen lines or more in BASIC or C. (continued) - • ..: .... i. - "iiggi
another function.
Modules can be tested and corrected separately, then easily combined.
Although many programmers believe APL is difficult (mostly because the compact code uses special characters to symbolize its large variety of functions), those new to programming will find it easy to write simple but surprisingly powerful programs, (Experienced programmers usually have to overcome serious tendencies to iterate.)
Documentation My first actual experience was with the software in a Beta test form, and only the on-line documentation a rather severe test of the user friendliness of the package. But APL.68000 takes advantage of the Amiga Intuition interface so well that it is easy to get started, Double-clicking the APL disk icon produces a window of workspace icons, including one that opens a clear workspace for new material. The rest of the workspaces have descriptive names, such as AMGRAPH, AMFILE, and AMTOOLS. Opening each reveals a set of functions for Amiga graphics, file management, mouse
parameters, etc. One might expect these, or at least hope for a library of defined functions to be used in programs along with the primitives that make up the APL language.
The documentation provided by MicroAPL for the Commodore Amiga system is very good. There is a well done 60 page booklet detailing the special Amiga facilities, and a 300 page, spiral bound manual for the APL language. The second section, "Getting Started," is a model of clear, sensitively paced introductory lessons which integrate straight information with well posed examples for hands- on practice. Another section covers "APL Concepts," defining the workspace, explaining data structures, describing built-in functions and operators, and developing the theme of user defined functions.
The last and largest part of the manual is the "Reference" section. The formal and detailed definition of APL.68000 is found in the reference section. The index and table of contents also seem competent. The worst complaint I can make is that throughout the language manual, overstruck characters are badly printed and hard to read. But the content is understandable and effective. In short, I think most people could quickly learn to write productive code using these materials.
Workspaces The functions and variables used for a particular project or task in APL are typically stored together in a workspace that has the character of a subdirectory or a large file. APL.68000 saves workspaces with an icon, and the workspaces can be accessed with either mouse or keyboard. Functions and variables can be copied easily from one workspace to another, allowing the development of extensive and flexible libraries of program modules. The Amiga package comes with eight such libraries, for accessing graphics, sound, files, menus, requesters, windows, I O, and miscellaneous
1 will describe AMGRAPH as an example. This workspace has functions for pen movement and line drawing, and a POLYLINE function that draws a series of lines connecting any number of points defined by a matrix of X, Y coordinates. Other functions draw and fill rectangles, polygons, arcs, and ovals, and there is flexible control of colors and linetypes, as well as fill patterns, which are controllable to the level of individual pixels. Labels or text in a variety of styles can be inserted anywhere in the field. These well designed low-level graphics functions provide effective direct access to
the Amiga's color graphics capabilities (but not, apparently, to the sprites and bobs used in animations). Combined with the APL language, they constitute a remarkably facile development environment for graphics applications. The default screen for drawing is the original APL.68000 window, but another workspace, WINDOWS, contains functions that allow creation of user defined windows and new logical screens. Here again, the result is flexible control over resolution (up to 640 by 400 pixels), color (up to 32 colors), and window placement and dimensions.
The SOUND workspace is also very interesting and easy to use, with a similarly broad spectrum of functions tailored to the Amiga's capabilities.
Without going into detail, 1 can say all the libraries of Amiga specific functions are thoughtfully done. The result is the Amiga and APL are mutually enhanced.
A demonstration workspace gives a general introduction, presented by an APL function that randomly selects a sequence of descriptive text and graphic modules. While the workspaces previously described contain only locked functions (1 hope this is changed in later releases) many functions are open in the DEMO workspace. Because they have excellent internal documentation, they can be used as models for user programs. Such models are very helpful, especially for new users, since they act as a "picture worth a thousand words." APL's compact nature can be forbidding, but I think this workspace
is a good beginning for an effective on-line introduction. With a broader spectrum of open functions performing both simple and sophisticated tasks, it could serve as an important source of education and encouragement for newcomers to the language.
Multitasking APL.68000 utilizes multitasking in a number of ways. For example, the VT100 style terminal emulator (which was easy to set up and worked perfectly) can be called under program control or from the menu bar. In either case, it operates as a task, and coexists happily with concurrent APL or Workbench activities. Although a facility for downloading mainframe functions and variables does not appear to be provided in the emulator, it is possible to capture material by copying the screen representation from the terminal emulator window via the clipboard to a concurrent window or
workspace. This process also works for uploading, since the screen representation is automatically translated by the emulator. The emulator has both APL and ASCII modes, and they are easily switchable. I was able to work with no difficulty in both the CMS and the APL environments of an IBM 3081.
Multitasking makes APL on the Amiga even more flexible than the usual mainframe versions; several concurrent APL sessions may be generated. For example, the system function for printing text or graphics may be started in a window, then moved to background. The same interpreter is shared by separate APL tasks, conserving memory, and the tasks may be run either in a foreground background mode or in several screen windows.
Input can be made only to the active or foreground window, but processing and output to windows continues for all tasks.
Menus and Features The Amiga Intuition Interface is used naturally and effectively to manage APL functions and features. In most cases, it provides an alternative to keyboard commands. The PROJECT menu allows mouse and requester control for loading, saving, copying and dropping workspaces, and listing functions and variables. The EDIT menu manages the full-screen editor as a separate task. You can have multiple functions open, making it easy to copy from one to another or to the clipboard. The editor is handled either with the mouse or with keyboard equivalents, using Amiga or control keys.
Its response to various programming and typing mistakes seems generally graceful, and informative requesters are used to report errors and warnings. In addition, APL's standard "del" editor is always available, and works in the usual line- oriented manner, enhanced with cursor movement and editing keys.
An INTERRUPT menu provides Break, Suspend, and Resume functions. The terminal emulator can be accessed from the TERMINAL menu. Finally, a SPECIAL menu allows opening a new APL session, changing workspace size, and a choice of operation in an expert mode, where warning requesters (e.g., "Existing FNS VARS will be overwritten") are suppressed. Functions are also provided (in the MENUS workspace) for creating your own menus, and (in the DIALOG workspace) for setting up requesters within your own APL functions. This means these powerful features of the Amiga system are available to the APL
programmer, and that developers can capitalize on both the APL language and the (continued) Disk Access Floating Point Trig Function String Extraction Sorting Random Generation Screen Printing Looping Amiga's operating system. As a bonus for software developers, a run-time system is included with APL.68000, making it possible to create packages that are completely transparent to the end-user.
Considerable flexibility is provided by the globally accessible Amiga clipboard, which is available from APL and may be used to transfer text either between APL tasks or to any other window, by cutting and pasting. But my favorite feature is an even more immediate "session manager." It allows text selection on the screen (e.g., the previous command), using cursor movement or the mouse, for editing and resubmission as a command to APL. Having to retype commands in AmigaDOS has always struck me as unfortunate. So this is a special bonus; it is something that should be imitated in any
operating system. I think the computer should always be used for repetitious stuff, leaving the operator free for problem solving and creative work. The designers of APL.68000 for the Amiga appear to have a similar philosophy.
Performance I did several simple Benchmark tests comparing APL.68000 and AmigaBA- SIC. In some cases the differences are striking, but of course APL is a different type of language (e.g., it operates directly on arrays, without loops), and some of the results reflect style differences rather than practical comparisons of speed in actual programs. A disk access test opened a file, wrote 1000 lines of 46 characters, closed the file, reopened it and read back the
46. 000 characters to memory.

3. 6 The floating point test did
10. 000 multiplications and stored them in an array, and the
trigonometric test did the same for 10,000 sine calcula
tions. A string test used a loop that extracted a substring
10,000 times. A BASIC ripple sort was compared with APL's
"grade- up" primitive function, and the generation of 1000
random numbers, with and without screen printing was
compared. Finally, a loop with no processing was repeated
10,000 times.
The results (in seconds) are shown in Table 1.
These results indicate that APL.68000 interfaces well with the Amiga, with both disk access and screen printing more than twice as fast as in Ami- gaBASIC. The math results are mixed, but it is worth noting that APL.68000 uses larger real numbers for such calculations, which may have slowed the repeated trig function. When looping was required for the APL function, as in the string extraction, BASIC was more than 3 times as fast.
The plain loop test shows part of the reason: 10,000 loops in BASIC requires
3. 6 seconds; in APL 49.7! The most startling difference was in
the time for sorting 100 random numbers. BASIC took 39.6
seconds, while the APL function was so fast it was hard to
measure an indication of the power provided by APL's large
number of primitive functions and operators.
On another level, the overall philosophy of APL is oriented not so much to speed as to efficiency. A few examples will demonstrate the efficiency and simplicity of APL programming.
In Figure 1, the variable V is created by drawing 20 random numbers from the set 1 to 200. V is displayed in its original order, then SORT is created with the grade up primitive (this is the process used in the comparison test above). Finally, the mean of V is calculated using only six keystrokes.
Figure 2 shows the APL editor with a user defined function that computes and displays a statistical test and related values. The last line presents (just as a curiosity) the same calculations programmed in the infamous one-line style that once characterized APL. Figure 3 shows the output of an easily readable eight-line function that creates a new window and uses a few items from the graphics library to display and label data from a white noise simulator.
Conclusions For anyone who already knows APL, this software is a splendid enhancement for the Amiga, which is capable of turning APL into a surprisingly effective substitute for an IBM mainframe running VSAPL. For others, I believe the combination of Amiga's Intuition with APL.68000 may remove the barriers and diffuse the myths that have prevented APL from reaching a large audience.
The distributor is making a commitment to education, and has provided the APL.68000 package to some 300 high schools around the country. The price is S99, including the runtime version, making this package not just affordable, but a terrific value. There is currently a program of substantial discounts for students and educators.
Versions are also available for Macintosh, Atari ST, and as a 68000 coprocessor board for the IBM PC XT AT. This could mean a rapid growth of interest, and good applications software, especially since the Spencer Organization will support developers of runtime applications in APL.68000 $ 99.00 Requires 512K Spencer Organization, Inc. 366 Kinderkamack Road

(201) 666-6011 Recently, I bought a hard disk for my A2000 and
discovered many Amiga packages lack hard drive support, by
John Steiner Bug Bytes The Bugs & Upgrades Column Some
programs cannot work on a hard disk at all. There are a few
commercial programs that demand to be in the ROOT
directory. The VIP Professional spreadsheet is one; Digi-
Paint is another. It works from a subdirectory on a hard
disk, but does not load its title screen and does not save
pictures with icons, unless it resides in the ROOT dir.
When writing software, developers should minimize special
startup sequences. The list assign commands in my startup
sequence is nearly a page long.
MiceoSearch is shipping City Desk version 1.1. The desktop publishing program now accepts files created with Scribble! And WordPerfect, A separate clip art disk of 25 pictures is included also.

expansion drawer on the A2000, If you have read error
problems on a hard disk when the Amiga is in overscan mode,
you need the new driver. It has been posted to all the
major communications links, or you may get it from your

Publisher Plus is a replacement and upgrade for Publisher 1000. Many bugs have been fixed. A couple of new features have also been added to make page-creation easier. Improvements include selecting a directory to work on. When changing directories, Publisher 1000 locks into that directory for good. This problem has been fixed with Publisher Plus, and the directory requestor now includes "select" gadgets for dfO:, dfl:, and dhO:.
Publisher Plus has a much faster TYPE mode when editing text within a guide. Publisher 1000 was really slow in this mode. The program also allows you to Lock and Unlock elements on the page. When they are locked, you can't move them, so putting layers of guides in place becomes a much simpler process.

(415) 571-7171 x379 David Britt of Madison, MS reports an
apparent leap year bug in CLImate.
No matter what date your system clock shows, if it is a leap year, and you are printing an ASCII file and putting the date on each page, CLImate prints a date one day earlier. In other words, if the system clock has March 10, 1988, CLImate prints out March 9, 1988. David tested this for other dates and years, but only leap years showed the problem. I tested my version of CLIMate, the latest available, and it has the same problem.
1 also found WordPerfect exhibits exactly the same symptoms with its date function, implying that the problem might be a bug in the Amiga system date function. On the other hand, David tested Maxiplan, and I tested Analyze!, both of which handled the date correctly. I have also used several other programs that use the date function that work properly.
Professional Page from Gold Disk has a problem that took several hours for us to track down. After developing a newsletter for our local users group, I tried to print it. The document would not print on our QMS laser printer. 1 printed it to disk, and tried to copy it to the printer still no luck. After trying to print each page separately, pages two, three and four printed fine, but page one would not print. We selectively removed articles from the page, and finally determined which article was causing the problem.
By deleting one paragraph at a time, we traced the problem to the paragraph that wouldn't print. In that paragraph was an underlined phrase.
We deleted the underline and the document printed. As it happened, the underlined phrase also was hyphenated, so we shut off hyphenation, re-underlined the phrase and it printed again. The obvious workaround here is to be sure to turn off hyphenation for any phrase that must be underlined. Thanks to Jacques Chatenay for spending much time working on this problem.

Fr ..j r, mm amS: For the Amiga 2000... MicroBotics means Amiga-Power!
Whichever Amiga you own-or plan to buy-we have the expansion you need HardFrame 2000 Super Speed DMA SCSI Interface If your application calls for super-speed uninterrupted access to your harddisk, HardFrame 2000 is your answer. This is a high- end, no holds barred SCSI interface that operates at bus speeds. With cable pinouts designed for compatibility with low cost Macintosh hard drives, one HardFrame 2000 can support up to seven devices.
Word-length data transfer, FIFO buffering, true DMA, all mounted on a metal frame suitable for mounting standard SCSI 3.5" drives "hard-card" style (or, if you prefer, cable connected to a bay mounted or external disk). Available March April. Suggested List price S329.
SB2000 Adaptor Card StarBoard2 Portability Large numbers of MicroBotics Star- Board2 owners have moved over to the A2000. To protect their investment in our technology we've made available a simple, low-cost adaptor card that permits the installation of a "de-cased" StarBoard2 inside the Amiga 2000 (in the first 100-pin slot).
When adapted to the 2000, StarBoard2 is still fully functional autoconfiguring memory plus you get access to all the StarBoard2 MultiFunction options- StickyDisk, Math chip, parity or the new SCSI Module. Available now. Suggested list price is only $ 49.95. 8-UP! FastRAM Maximum Memory in One Slot!
The FastRAM card that every Amiga owner will eventually come to -why limit yourself to the possibility of only two megabytes per slot when 8-UP! Will take you all the way to the top of the autoconfiguration memory space of EIGHT MEGABYTES! 8- UP! Uses an exclusive MicroBotics- designed memory module, PopSimm, that frees the user to install his own, conventional DIP-style DRAM in standard SIMM sockets on 8-UP!. If you use 256k PopSimms you can install two megabytes on 8-UP!; if you install 1 meg PopSimms, you can install eight megabytes on one card! In either case you can install the memory
chips yourself for maximum flexibility and mininum cost.
8-UP! Will also accept conventional SIMM memory. 8-UP! Is a power efficient, zero wait state, autoconfiguring design. 8-UP! Will be available 2nd quarter of 88. Suggested list prices start at $ 199.
For the Amiga 500... M501 Memory+Clock Half a Meg at a Great Price!
As we are all coming to realize, a 1- megabyte Amiga (at least) is a necessity not an option. When you add the inboard 512k memory and clock module to your A500, make it a MicroBotics-brand, plug compatible work-alike. It uses the exact same kind of memory and the exact same dock and battery. And note that just like Commodore and unlike some third-party expansions, we use a long-lived rechargeable Ni-cad battery by Varta- which you'll never have to replace! Set the MicroBotics clock using the same software (on your WorkBench disk) as you use for the Commodore dock. What's the
difference? You get to keep $ 21 compared to the Commodore version. M501 has a suggested list price of only $ 179.

(718) 296-2385 Proletariat Programming A Look at Freely
Distributable Compilers for the Amiga by Patrick Quaid The
Amiga community is blessed with several freely
redistributable compilers of various languages. Reviews and
articles on these compilers almost always include the
caveat that, while the compiler in question is useful to
help beginning programmers learn the language, a commercial
compiler is a minimum requirement for writing real
But what are real programs? Perhaps they are programs someone else might need, programs that do some work, provide a service, or even play a game. Can something like this be written using a freely distributable compiler? Can those who would rather not spend hundreds of dollars on a language system participate in Amiga programming? You may be surprised.
Let us take a look at three of the freely distributable compilers available to Amiga programmers. (There are many others, but this article is not a book at least, not quite.)
ETHZ Modula-2 ETHZ Modula-2 is the Swiss Federal Institute of Technology's Modula-2 compiler. It is included on Fred Fish disk 24 and was reviewed in Amazing Computing V1.10. I hope to cover different ground than that article did.
The compiler is in the same vein as the Pascal-s and Pascal-p compilers a public domain program written in part by the designer of the language. Dr. Niklaus Wirth. Unlike the Pasca!-s compiler, however, ETHZ Modula-2 produces true 68000 native code, although it does not create executable files. It is evidently related to a Macintosh Modula-2 compiler as well as the M2Amiga compiler from AMSoft.
Modula-2 contains virtually every control structure and variable type commonly available in popular languages, and ETHZ Modula-2 supports every aspect of Modula-2 that I was able to test. Sets are supported (limited to the standard 16 components), as are procedure variables, real numbers, and all the loop structures of the language.
Some standard library routines are provided, but many are not. The standard module InOut is provided, but only for string and character types.
Neither Writelnt, WriteCard, nor the ReallnOut module are included (the review in AC VI. 10 provides a Writelnt procedure). MathLibO is also absent. Modula-2, of course, is designed to make an expansion of functionality as easy as possible, so these functions can all be added by the programmer.
Contrasting this lack of standard libraries is a veritable wealth of interesting procedures and example programs. The most important is LibCallO, provided in the module AMIGABase. This procedure, coupled with a type Regs that mimics the 680x0 register set, allows programmers to access any system routine for which they know the offset, much like assembly programs. Other interesting procedures include TranslateO and NarrateO, which are as simple to use as they appear, and dec68k(), which takes a procedure as an argument and basically acts as a disassembler.
Examples are provided for each of these.
The example programs include working demonstrations of an Intuition menu, simple sprites, opening a CLI, using the requester, creating speech, sensing CTRL-C, and several uses of AmigaDOS, including a type of Info command and a date printer.
Also included are routines for (believe it or not) using the printf, sprintf, and fprintf routines in the Exec library from Modula-2. These examples are provided in lieu of documentation, but working examples are a programmer's best friend. Along with this lack of documentation, there's no explanation for the error numbers generated by the compiler. For what it's worth, I have included my interpretations of the errors I found.
The system obviously lacks a linker.
The compiler produces object modules which are loaded and run by a bulky program called Aload. Even the compiler is run through Aload, which provides functions that would otherwise be undertaken by a combination of a linker, loader, and startup code.
It loads all required modules, links them in memory, opens a window for standard input and output, etc. In some ways, this loader is novel. For instance, each object module is loaded only once, much like the Resident command. If another program requests the same module, it is linked in memory rather than loaded from the disk.
(continued) This scheme raises some obvious questions about memory and cluttered disks, as well as some more subtle concerns. Since a compiled program does not keep a unique copy of an imported module, it is vulnerable to changes in that module. Obviously, Modula-2 must keep track of which version of a module is referred to by other modules. For example, recompiling the definition file of the module Clock invalidates all other Clock files, even if no changes were made. Thus the compiler, which uses the Clock module, will not be able to load properly. To fix this, the Clock implementation
module and the compiler would have to be recompiled.
However, the source is not provided for either of these, so be sure to keep copies of all the object modules.
Aload is more annoying than necessary because it is case sensitive on its input line. It will terminate if a file is not properly capitalized or spelled, or not found, releasing all those painstakingly collected modules. It also requires that the module name exclude its .OBM extension. After it loads its object modules with Aload, the compiler presents the user with a prompt. It is not case sensitive for its input line, but it does require that any extensions be included. Since it is difficult to keep these inconsistent formats straight, it does not terminate if a file is not found, just
to be irritating, the compiler accepts virtually anything but a letter, number or period as an end-of-Iine marker for its input line. The Return key is included in this set, as it should be, but so is most punctuation, all the control combinations, and the backspace key, so watch your fingers. Regardless of the success of the compilation, the compiler returns its input prompt, a handy feature all compilers should incorporate.
ETHZ Modula-2 Error Numbers My thoughts as to the meanings of the various ETHZ Modula-2 error numbers follow. Many of these are simply the type of mistake that caused the problem, and particularly questionable in terpretations are marked by a question mark. Note that most of these were found by introducing deliberate errors. The others?

With a capable linker, this compiler might be my favorite. It is fairly fast and provides the tools needed to write complete, rock-solid interfaces to all Amiga routines; all in the context of Modula-2, which 1 find the easiest language to develop with. The compiler handles all of Modula-2 with no apparent idiosyncrasies. But imagine releasing a program written with this system. The end user would need to create something called M2:, then copy all the required object modules into it. The user would then need to run Aload and type in the name of the program with proper capitalization, at which
time Aload would create a full sized window on the Workbench screen, which could be a waste of memory. There is no reasonable way to run an ETHZ Modula-2 program from the Workbench. Even with a batch file to do the bulk of the work, it would have to be one terrific program to justify the trouble.
If you are writing an error lister or similar program for use within the ETHZ Modula-2 environment, none of this presents much of an obstacle. In fact, if these programs were written in ETHZ Modula-2, most of the need for a second CLI would be removed.
Perhaps someone can use the system to write even the most modest of linkers. Until then, it is certainly possible to write large scale programs with ETHZ Modula-2; it's just not possible yet to let anyone else use them.
PDC PDC is a freely distributable optimizing C compiler, originally written by Matthew Brandt for a UNIX system and moved to the Amiga environment by Jeff Lydiatt. It is available on Fred Fish disk 110, which also contains an assembler and Blink version 6.7, PDC produces 68000 assembly source code rather than object code directly, which is why an assembler is included.
The introductory file on the Fish disk notes several bugs and deficiencies of the compiler. In fact, the author claims in the very first paragraph that it will not work a claim I am happy to contradict.
Actually, PDC has several commendable features. It is small (just over 50K on disk. PDC, the a68k assembler, and Blink all fit on the RAM: disk of a 512K machine comfortably).
It is fast, and it produces very compact and fast code. It is also quirky, buggy, and comes with no header files, little in the way of function libraries, and nothing playing the role of Amiga.lib. Note that it is free.
PDC accepts most C contracts, but has notable limitations. All constants are considered long words: meaning 4- byte values. (I'm afraid there will be quite a bit of assembly talk in this), which can be a problem when passing parameters. Apparently, Global variables are not allowed. The compiler simply will not accept the concept of a void function (it will not accept the word void, but omitting it does the trick).
There is no shortage of similar quirks, but of course they are not fatal. But some are. Several times, through seriously deranged syntax errors I brought on the Guru. Nevertheless, these can be worked around, because the PDC programming environment (as it were) is remarkably flexible.
In a second-hand way, PDC subscribes to the standard Amiga object files and libraries. This means, for instance, that the programmer need not write his or her own printfO or puts() functions; they can be found in Amiga.lib. This also means that a standard linker like Blink can connect the C code produced with PDC to properly written assembly (or possibly Lattice
C) object code you may have lying around. The point is that
nearly any deficiency can be fixed, with varying numbers of
backflips. One quick example would be this assembly code: XDEF
VariabteNdme SECTION BSS VariableName ds.l 1 END Assembled and
linked to your program, this creates what amounts to a
global variable called VariableName to a C program that
includes a line like "extern int VariableName" where
appropriate. Note that similar extern statements are not
required for external functions.
As noted above, PDC is an optimizing compiler, which is no idle boast. Oft- used variables and procedure addresses are automatically housed in registers, and several arithmetic operations are condensed quite effectively. For example, PDC will convert a remainder operation into a 68000 AND instruction if the second operand is a power of two. Thus Var=Var % PowerOf2 becomes: MOVE.L Var,d0 AND! . PowerOfTwo-l.dQ MOVE.L dO.Var This is up to seven times faster than the normal algorithmic method involving a DIVS instruction. Oddly, this optimization is carried out only on an equation in the above
form; something like Var%= PoweiOf2 is always figured algorithmically. The sequence is unfortunately never converted to the single instruction "AND.L PowerOf2-l,Var", although additions, subtractions and assignments can take that form.
Similar optimizations are wrought upon multiplication and division operations, using shifts in place of fcontinued) Examine the code immediately before and after the call to _c9eswitch in the assembly file (produced by PDC) in order to get a better idea of how this works. Note that most subroutines called from PDC should set up a local stack frame and save all registers used; cswitch.asm does neither.
::XDEF CODE c*switch move.1 c% switch a?)+,aO;POP the table addr IS .•default case?
;lf so, go away tst.l beq.s (aO) 2S crap.l 4(a0),d0;d0 holds compare val beq.s 3 5 ;1£ equal, return addq.l 18,ad ;ga to next entry bra.s IS ;and try again addq.l H,aQ ;for default, shift aiove.l (aO),aO .‘get return address jjnp (aO) 23 33 MULS and DIVS when possible. This results in a similar savings in time, but the same restriction applies. The moral of this story is always to use the form "Var= Var * Constant" when the constant is a power of two. Also note that in PDC this form is never slower than the "Var *= constant" form, PDC also combines constants when possible, making, for example,
"4*4" in the source simply "16" in the assembly produced.
Having raved about the optimization, I direct your attention to the Fibonacci benchmark results, in which the optimized version is actually slower.
The only optimization wrought upon this program is storing variables in registers, which in this case saves very little time. Most of the work in this benchmark is making calls, during which register variables must be pushed onto the stack, whereas normal variables are already on the stack.
Cswitch.asm The negligible savings in computation time is more than offset by the added time of saving registers. Not a very likely situation, but something to look out for.
Like most modern languages, all variables not declared static are held on the stack. This includes registers, which, as ! Mentioned, are saved when necessary. Since PDC assigns its own names which it does not export to static variables, and since it does not allow its own global variables, variable names are never exported. Those of you who have used Amiga.lib before know that it requires someone to export something called IntuitionBase in order to access Intuition functions (or GfxBasc for Graphics functions, etc.). There are several ways to get around this. I decided to rewrite Astartup.asm
so it opens Intuition and Graphics in the openDOS procedure, then closes them in the exit code.
Astartup.asm is included on the disk with PDC, but you would play with whatever procedure you use. If you are not as lazy as I am, you could use the sort of global variable kludge listed above, which could be more efficient at run time.
One flagrant bug I found is in procedure calls. If the first argument of a call (the last one pushed on the stack) is an expression, as in foo(num + 1), the PDC generates incorrect code, which takes the form: MOVE d0,-(a7) JSR Joo dO here holds the result of the expression, and could be a different register.
The first problem is that there is no length indicator on the MOVE instruction: a68k in this case assumes a word, although an int or long parameter should be a long word. The second problem is that the last parameter is not removed from the stack. There should be a statement like "ADDQ.L 4,a7" directly after the call. If there was more than one parameter, a statement to this effect is already present, but must be increased by four.
The obvious fixes: either store the expression in a variable and use that as an argument, or edit the assembly code produced. Note that since this affects only the first argument, normal printfO calls always work properly.
! Also cannot seem to get the switchO function to work properly. Blink complains that something called _c%switch has not been supplied by anyone. The documentation does not mention this so it is probably my mistake, but I have included a short assembly program called cswitch.asm that will fix the problem if linked to the code that uses a switch case statement. This illustrates not only how to fix bugs of this sort, but also how to add more useful assembly functions to your PDC programs.
To write complete programs with PDC, you will need to write header files (which can be culled from the ROM Kernel Manuals as the need arises). Then get a library (like Amiga.lib if you own Lattice C or the Metacomco Assembler, or smalllib from Fred Fish disk 92). You can use the assembler from the Fish disk 110 or any other Motorola standard assembler. Later, you will want some standard functions like getsO, which you can write yourself as you need them.
When PDC tells you something is amiss even though you know it's correct, don't fight it. Try to reshape it or attack it from another direction.
When you've pinned down the problem, write it down somewhere and try to fix it or just avoid it. You will need plenty of patience, and no doubt some assembler expertise. Remember that PDC, like many compilers, is not teTribly adept at recovering from errors; the first error normally triggers many false ones.
The fruit of this labor will be very small code, which, for many operations, is about as fast as you'll find, since it does no error checking.
If you don't mind meddling with the assembly code you can easily make it faster than any high-level language.
Your source code might have to be massaged through the compiler and will not be able to use the full power of C (like floating point numbers), but you should be able to produce fairly complex programs. The only bugs I have run across that aren't in the documentation are listed above. And all the problems I have found had fairly simple fixes. The tallest hurdle in using PDC is convincing the compiler to recognize constructs, but anything missing can be added in assembler.
If you like programming in assembly, this compiler is especially useful. You can write all your control structures in C, then insert your assembly code where necessary. Likewise, you can write tricky equations in C to get a model for an assembly procedure.
PDC supplies no comments in its assembly output, but the code is easy to digest and even learn from. PDC removes much of the tedium involved and, if you are like me, cuts down significantly on logic errors. In his documentation for Draco (see below) Chris Gray writes that anyone who really tinkers with compiler-produced assembly code has to be crazy. Well, I do like to tinker with it, so I am in a position to agree with him wholeheartedly.
If C is your job or your life, you'll need a commercial compiler so you can complain with conviction. Those of you interested in writing compilers could undoubtedly learn a thing or two from the C source code (Manx flavored) included on the Fish disk. It would be not only an interesting exercise, but also a great benefit to the Amiga community if some C wizard would undertake the next revision of PDC.
But what about those of us who simply want to write C programs?
PDC is no competition for commercial offerings, but it does most of what it is supposed to do. My background is in the non-toxic languages, but with PDC, I feel confident that I can write full scale programs programs that are smaller and faster (and in some ways nastier) than those of any other language I know, My intuition.h file is expanding, my graphics.h file is nearly complete, and my other header files are growing as necessary, so I'm well on my way to a complete C system; no apologies, no excuses.
Draco In 621 B.C. Draco (also known as Dracon) began passing laws in Athens that called for the death penalty for even minor crimes. In memory of him, the term Draconian is used describe a rigid law or cruel punishment. In an age when programming languages like Pascal and Ada are named after people, Chris Gray apparently named his pet language after Draco. Of course, the same word in Greek means serpent, so that's only a guess.
(continued) Draco is a structured programming language written by Gray for CP M systems several years ago, and ported to the Amiga just recently. The compiler, libraries, header files, documentation and example programs are available on Fred Fish disks 76 and
Draco is similar to the rest of the common procedural languages like Pascal, C, Modula-2, and AmigaBASIC.
At first glance it appears most like C, with liberal doses of Pascal. The common control structures such as "if' statements (with "else" and "else-if" clauses), "case" statements, "for" loops and "while" loops (which are flexible enough to act as true "repeat" loops) are included, as one would expect.
Standard variable types like long and short integers, characters, Boolean values, pointers, arrays, and structures are supported, as are less common types like enumerated types and unions. Draco supports normal and long real numbers and an operator type, but these are not yet supported in the Amiga version.
Indeed, Draco has much more in common with the more popular languages than it has differences.
Most of its features can be found in some other language, although none of the other languages has a similar combination. For instance, simple output is handled with writeO and writelnO calls, just like Pascal, although in Draco the field widths can be specified with variables. These, along with the related readO and readlnO calls, make up the simplest terminal input output this side of BASIC. Declaring variables and constants is much like C, although designed more logically than C, in my opinion. Procedure declarations are similar to Modula-2, with the parameter types listed within the
parentheses and function types listed at the end of the line. Equations look most like C, with more symbols than are absolutely necessary, although at least "and" and "or" can be in English. Draco, like Pascal and Modula-2, makes sure variable types in assignments and equations are the same, which might be where Draco got its name. (Some C programmers consider loose type checking a Constitutional right.)
Any language that checks types strictly must have a method for circumventing that control. Draco uses the function "pretend," which takes an expression and a type as arguments, then preWhat’s Draco???
What follows is a simple Draco program that opens a window on the Workbench screen, then waits for the dose message from Intuition.

Modula-2 has a more elegant solution, but "pretend" seems to do more conversion work. Let's face it, it is named realistically.
Draco also offers "if" and "case" expressions. The idea here is that a variable be assigned, for instance, to an "if" expression, which would look something like: Var.= if OtherVar 50 then writelnfThe other variable is '.OtherVar); OtherVar + 50 else OtherVar fi: Note the final line of each clause is simply an expression. The meaning of this code is clearer, 1 think, if "Var:=" is simply inserted before each of these expressions the statement form. The expression form may have a convenient use that 1 have yet to run across.
Function values are returned similarly, with a line consisting only of an expression.
Draco's conditional compilation facilities are similar to those of Modula-2, in which an "if" statement that evaluates to "false" (either as a constant or constant expression like sizeofO), during compilation is simply not compiled at all. This allows the inclusion of a Boolean constant called, for instance, DEBUG, which can be set to "true" in development. Debugging code can then be included in the source surrounded by an "if DEBUG" type statement. When DEBUG is set to "false", the debugging code is not included and does not inflate the size of the resulting program. Draco also includes a
method for issuing actual compiler errors from the source code, so the bases should be well covered.
A programmer who has used Pascal, Modula-2, or even AmigaBASIC, and who has even the most rudimentary knowledge of C can learn Draco in a day. It's not easier than most languages, but it's not more difficult, either. It amounts to using the same old tools and methods with a variation of the old syntax rules. A simple Draco program that opens a window and waits for the user to close it is included to provide a limited illustration of Draco.
On the two distribution disks are a complete set of Draco include files, arranged in files and directories similar to the assembler and C sets, and written according to Gray's proposed Draco conventions. There are also many libraries to be linked to Draco object files. These all have corresponding include files, and mostly concern Amiga functions like the dos.lib or intuition.lib. Others provide extra Draco functions. Crt.lib, for example, provides a long list of screen handling functions, from simple things like placing and finding the cursor to a full set of form definition and input output
routines. Along the way are simple functions for asking questions, centering and highlighting text, and even turning automatic handling of the Control-C combination on and off.
These and other functions provided with the distribution show the work Gray has put into the system over the years. There are, for example, a set of string handling functions, many input output options including simple random file access, memory management tools, and time functions. The depth and breadth of the support is stunning. The balance of the distribution is documentation, helpful batch files, an editor written in Draco and several example programs, an absolute requirement for an unfamiliar language. For one whopper of an example program, see Empire on Fred Fish disk 118; about
350K of source code is included.
Draco is designed to be linked by a smart linker that includes only those routines actually called. Gray has yet to port the Draco linker to the Amiga, however, so the system currently uses Blink. Unfortunately this means that Amiga Draco programs are very large, since some of the lavish support provided by Draco might go unused by many programs. Gray does write in his introduction that he plans to port his linker, which should help out significantly. Gray also notes that "code quality is not so good" with this version, which is bome out by the benchmarks. This implies that he plans to speed
it up somewhat, which is always welcome.
The compiler itself is apparently written in Draco, although the source is not provided. This has a pleasant effect: as the Draco environment improves, the compiler itself gets smaller and faster. The compiler is already less than 80K on the disk, and can join Blink on a 512K Amiga's RAM: disk comfortably. As the benchmarks show, the compiler is quite fast. Contrary to what its name might imply, Draco flags errors with English sentences pulled from a text file which can be edited as necessary.
Those errors are, in turn, fully explained one by one in a documentation file.
The Amiga version of Draco, it appears, is a shadow of its more mature CP M sibling, although of course it is complete as it stands. The Draco linker provides a form of modularity, complete with automatic startup and termination procedures (going Modula-2 one better). The documentation mentions the existence of a companion assembler, disassembler, and librarian for the Draco system. When and if these tools are ported to the Amiga, Gray's Draco should be among the most powerful Amiga programming environments available. As it stands, it is a full featured compiler whose only real drawback is
the unfamiliarity of the language.
Having given the Amiga community a taste of what it can expect from Draco, perhaps Gray could release the complete version as a more commercial product. Or, in a fit of marketing brilliance, he could release just the additional components, with the addition of a debugger, as commercial products (or would that be too confusing?). In any case, one would hope that the rest of the system finds its way into the Amiga. At least my Amiga.
Benchmarks The benchmarks are not, of course, meant to compare the three compilers directly; there are many more important factors to consider. In fact, no particular effort was made to create equivalent categories for the compilers.
Instead, compare the results of the benchmarks to what you require in a compiler. Run time results for the TDI Modula-2 compiler, with all error checking disabled, are provided in order to present a broader basis for comparison. No other figures are provided for the TDI compiler, since they would have no relation to apparently analogous results for the free compilers.
The Math benchmark just carries out simple math operations a ridiculous number of times. The multiplication, division, and remainder operands were specifically chosen so that PDC would not optimize them out of existence. Be assured that if powers of two were used, the PDC optimized run time would be much faster than it is.
The Fib benchmark calculated the 30th Fibonacci number by the slow and inefficient recursive method, to test the efficiency of function calls for each compiler. Believe me, this program makes a lot of calls.
The Sieve and Prime benchmarks were pulled from Amazing Computing's review of TDI Modula-2 in VI.9. The TDI results are also from that issue.
These benchmarks are included because the most common and important use of computers is finding prime numbers.
The Prime benchmark normally prints hundreds of prime numbers to the screen, which makes the benchmark's final time rely heavily on printing time. ETHZ Modula-2 had to resort to the Write]ntO procedure from Amazing Computing VI, 10 for its output, and since its slowness definitely skewed the results, I ran another version of the program that computes the primes but does not print them. This has the effect of stealing the last remnant of utility from the benchmark itself. It also shows something about the relative printing speeds.
F continued) environment is the inclusion of complete headers and libraries, as well as fertile support functions. The compiler itself is solid, with no obvious bugs and only real numbers and operator types as unimplcmentcd features. The code is slow and fat, and will hopefully speed up and slim down, but more importantly, it works as expected. As the CP M system moves to the Amiga, Draco will become stronger and more complete.
As it turns out, PDC is the only real challenger to Draco for general purpose programming. It has the advantage of being the most popular language among Amiga programmers, and also produces faster and smaller code then almost anything else. There are no header files or libraries included, however, and the limitations of the compiler make most of the existing header files inconvenient. Although In each case, the run times for ETHZ Modula-2 were cursor-to-cursor times for the first run of the program with only the compiler's modules already in memory. Subsequent runs would be quicker since no
loading would be necessary.
The build time for PDC and Draco are the cursor-to-cursor run times for a batch file that compiles and links a program using the RAM: disk as much as is convenient. For PDC this includes an assembly step, of course.
Conclusions Of these compilers, Draco is the best suited for general purpose programming on the Amiga. The unique language, regardless of its relative merits, must be considered a negative factor.

Unfortunately, most C programs need to be changed considerably for PDC to compile them. If you need or want C, however, this is a useful program that becomes much easier to use effectively as you get more experience with it.
ETHZ Modula-2 simply cannot be used for general programming, since every program requires Aload and something called M2: (perhaps this would work better on a hard disk).
This is unfortunate since it is a very complete version of Modula-2 that includes a handy ability to access all the Amiga's features. Modula-2 is, in my opinion, the easiest language yet to write large programs with, and this implementation does nothing to change that. For those of you who want Modula-2, a commercial compiler is the only real game in town. Happily there is a good selection for Amiga owners.
So choose your poison. Writing complete, useful programs need not be the exclusive domain of the aristocrats who can afford a compiler costing half as much as their computer did. There are free compilers out there just waiting to be exploited. In addition to these three, there is a related C compiler, a number of assemblers, a Forth implementation, XLISP, several specific purpose languages like the Adventure Definition Language, and others. Use them, abuse them, but if they help you, make sure you take care of their authors.
• AC* Picture by Warren Ring The Unified Field Theory Continued!
Two months ago, we started a series of articles on interfacing among a number of assembler functions (a collection known as a toolbox) with unified fields. This article is the last in a three-part series describing these functions. I've included source code covering disk I O, console I O, scanning a line of text for individual words, string manipulation, Integer ASCII conversion, and text display.
This month we'll finish this series with source code and examples. Add the text shown in this month's MACROS.ASM and WARLIB.ASM files to the text shown in last month's column. Later in this article, I'll discuss how you can obtain a copy by modem.
For those of you just joining us this month, the toolbox uses a data structure I call the "string buffer" for getting data to and from the routines in this toolbox. A string buffer can contain text strings, but it can just as easily be used for disk buffers. It may contain either binary or ASCII data, and is structured to have overrun protection and fast manipulation.
It consists of a long integer indicating the size of a data area in bytes, followed by a long integer indicating the current usage of that data area, in bytes, followed by that data area.
String buffers unify the interfaces to all functions in this toolbox, and simplify many coding operations assembler programmers find difficult.
The functions we'll cover this month can best be illustrated by the two example test programs.
Example One: Character Conversion Listing 1 shows examples of character conversion from ASCII to hex ASCII. The program allows you to enter a phrase and then displays the individual ASCII characters and their hexadecimal equivalents for each character you've entered, it demonstrates how the toolbox converts nybbles (4 bits), bytes, words, and long words from integer format to 1, 2, 4, or 8 character format, respectively. These character strings can then be displayed on the console or combined with other text. Listing 2 shows a sample run of this program.
Example Two: Integer ASCII Conversion Listing 3 shows how you can convert a signed integer from an ASCII string to binary form and back again. The program also shows you how to display a binary integer as 8 hex ASCII digits. You can use this facility to get decimal signed integer responses from the console, convert the values to long integers, convert values from signed integers to decimal ASCII strings, and display these strings on the console. Listing 4 shows a sample run of this program.
This operation can be tremendously useful in communicating values to and from the console.
Parting Words This entry wraps up the first in what I hope will be a series of assembler toolboxes. I'm going to take a few months off to work on another project. Eventually, I would like to get into serial and parallel port usage, multi-tasking, and floating point support in the next toolbox. These would enable you to write your own BBS and resident print spooling routines. In subsequent toolboxes, I would like to cover graphics support, If you missed the last two columns, and would rather get a copy of these files electronically, the files are currently available under the name ASMTOOLLARC
on People Link and BIX, and on the two BBS systems I regularly visit: the Los Angeles Amiga User's Croup BBS (LAAUG Line) at

Amiga with... The Companion ...a project that lets you open
doors into the Amiga’s Event Handling capability.
By Paul Gosselin PLINK: OLS389 - CompuSeive [73117.636) One day in August, I was sitting back in my chair, hacking away at a program that I was sure would one day make me rich and famous, when I needed to use the mouse. I stretched, but it was three inches beyond my reach. After a few grunts and groans, I sat up and used Mr. Mouse. As I sat back in my chair, I remembered the Amiga could be used without the mouse for many applications, so I decided to try it.
Well, if you've tried it, you know using the Amiga and Shift keys with the cursor keys, and then ALT to simulate the mouse buttons can be a little awkward. After trying that once or twice, I decided to do something to remedy this problem (many inventions came about because of laziness).
I mean, I am a programmer. I should do something to customize the machine so it works better for me.
That's how this project, code-named "The Companion," came about. I decided to write a program that would let me use the cursor keys to look at the Menu of a given window with greater ease than the current method allowed.
1 started by looking at the Rom Kernel Manual and the source code for an older version of PopCLI, a Public Domain program that uses "hot keys" in much the same way I wished to. Unfortunately, the version of PopCLI I owned used a lot of assembly language. Since I didn't relish the thought of getting wrapped up in Assembly Code, I took a second look at the Rom Kernel Manual.
There I found an interesting example program that would place an event handler (of one's own making) in the input stream before Intuition could figure out what it meant. This was just what the doctor ordered! If I just typed in that example, I could see events as they came in, and better yet, I could change the program and maybe modify the information. Right? Wrong! Well, at least at first.
After typing the example (along with the tiny assembly part, which was no big deal), I got everything to compile. But it just wouldn't link! Something was missing. Closer examination revealed that some necessary timer-related functions were not present in the code I typed in. Where were they?
Well, as the RKM stated, the missing functions were located in an example in the Timer section. Examination of the Timer section revealed that the functions were there in spirit, but not in name or syntax. After a little tinkering, and some thought concerning a section that had a few lines out of order, I got the program to work the way it was supposed to.
The next step in the project was a sort of sidestep. To view the Menu properly, I would first have to learn about the Menus and their structures. I discovered I could go about finding the Menu Structure for the active window, and then "walk" through the menu structure. Listing One shows how you can access just about all of the necessary information, and print it out just to make sure you got it. When you use the program, I would suggest you start the program you want to investigate (with the "run" command), and then perform a "wait 4" followed immediately with execution of the menu search
program. Before the wait is complete, you should have enough time to click inside the desired window. Redirection is also possible, and is suggested for long menu trees.
With that behind me, it was time to create. The first version of this project simply looked down through the Menu tree and expected that NextMcnu or Nextltem would give the next menu or item branch. Although this worked in theory, it did not always work in reality.
Several programs yielded humorous results. For example, pressing Right Arrow makes you move left, Down arrow makes you go up, and vice versa. You have to search though the current branch of the menu, and find what really is the next menu selection for appropriate Cursor presses.
THE LISTINGS Listing Two is the result of this effort. Listing Three is the small machine language section from the RKM. The setup of Listing Two, as well as the revised timer functions, are also from the RKM.

The major functions in Listing Two are: tnainf) handles setup and takedown of the input handler.
MyhandlerO gets events & decides what to do with them.
SNP0 sets new position in the menu, depending on where the pointer currently resides.
GoQ figures out where the pointer should go, depending on where it is and the dimensions of the menu.
IN DETAIL The main routine, taken from the ROM Kernel Manual, goes through the usual process to get things started. The Intui- tionBase Library is opened, the program sets its priority to twenty to avoid delays in processing, the input.device is opened, and the handler is added to the input stream. A priority greater than fifty (that of Intuition) assures that my handler wilt get the information before Intuition does, so !
Can modify incoming signals before Intuition acts on them.
Next is a forever loop which simply loops at a specified interval (via the WaitForTimer function), waiting for the user to type the key that disables the new input handler.
When the special key is pressed, the program breaks out of the forever loop, removes the special handler, and exits gracefully. For my purposes, I changed the original main function to modify what went on in the forever loop.
Listing 4 contains a working version of the ROM Kernel Manual event handler example that inspired this approach.
THE HANDLER The first argument to the handler function (myhandler) is a linked list of actual raw input events. These events can include, among other things, disk insertion removal, key presses, and mouse movements. (The original program simply passed this chain of events to Intuition without modification, but first copied all pertinent data to a "dummy" event structure.) Meanwhile, the forever loop prints out the last copied input event data, and if it notices that the FI key has been pressed (and released), it exits, removing the handler as it goes. Since Timer events can happen so often,
they are noted and passed directly to Intuition to avoid unnecessary delays.
My handler, like the original handler, returns immediately if the first event is a timer event. The event data is stored in the structure called "copyevent" which is checked by the forever loop in the main function. Also, a ForbidO call is made to suspend multi-tasking while changing (or viewing) crucial memory structures. After the top event has been copied, the handler scans the linked list for events of interest. Table 1 shows a list (from the include files) of the possible Input Event Gasses (IECLASS). If the event was not a RAWKEY event (i.e., not a keyboard event), then the handler
quickly goes on to the next event without significant delay. If no RAWKEY events are found, the handler makes sure to return the linked list of events to the next handler in the stream (Intuition, most likely).
Another way of speeding the processing uses the switch case functions to check the Input Event Code values (IECODE; see Table 2), which represent the actual key pressed from the keyboard matrix (see Figure 1 for the AlOOO keyboard RAWKEY codes). For easy programming and legibility, defmes were used. The first possibility accepted by the handler is the reverse apostrophe key (just above TAB), This is the hot key that lets you browse among the menus, using the cursor keys. The first thing checked is the Input Event Qualifier (IEQUALIFIER; see Table 3). This tells which other things, if any,
may have been going on during the hot-key press.
The tost for "LCOMMAND" ensures that the left Amiga key was being held down while the hot key was pressed, to keep the user from getting menus by accident. (It would be a mistake to change the function of a standard keyboard key.) Once the handler is satisfied that the user wants to browse the menu structure from the keyboard (remember, the mouse still functions), the handler changes the event from a RAWKEY press to pressing down the right mouse button. (Intuition assumes the button is held until a new event tells otherwise.) In addition, a dummy event is created to fool Intuition into
thinking that the mouse had been moved. How does Intuition know where to move the mouse? Well, a function called "go" takes care of that, and will be described a little later.
Before moving the mouse, the handler stores away special information, such as the mouse's original location. It also brings the pointer to the first Menu structure to be browsed.
Note that if the "go" function encounters an error while moving to the HOME position (arbitrarily located at the center of the first Menu header), the handler assumes that there are no menus associated with the current window, and passes the keypress to Intuition.
The next character that might be pressed is the RETURN key. This key tells the handler that the highlighted menu item is to be selected (the equivalent of releasing the right mouse button). Since we are working with Intuition, this event is all that is required to make the proper menu selection. Another dummy event, coupled with the button release, simulates the movement of the mouse back to where it had been when the hot key was selected.
The next presses of interest are the cursor keys. When the browsing mode is established, pressing cursor keys tells the handler to move the mouse to a new position (if possible).
After returning from the "go" function, the X and Y values for any mouse movements are stored in the "dummyevent" and "tempEvent" structures which are passed on to Intuition.
After exhausting all possible key presses of interest, the handler returns the pointer to the modified linked list of events to the next handler in the input stream. This could be one of your own design, a program like PopCLI, or Intuition itself.
GOINC PLACES Movement of the mouse requires a call to the routine "go."
Go takes two arguments: where and how. Where is HOME, UP ARROW, DOWNARROW, LEFTARROW, or RIGHT ARROW. How determines if one of the shift keys has been pressed.

TABLE TWO i Event Codes Please allow four to six weeks for
The first order of business is finding out where the mouse is. If the mouse is sitting atop any available menu item or subitem, this section will find it and set all of the variables for the selected menu item. From here, the program can figure out where to go when a cursor key is pressed. Unfortunately, this function uses a lot of local variables.
Generally, variables starting with "a" are associated with the Menu Header; "b" corresponds to actual Menu Items; "c" is for Menu Subitems. For example, variable "c" is the selected Subitem in the linked list, "cup" tells where to go in the linked list if the "UPARROW" key is pressed, and "cdn" tells where to go if "DOWNARROW" is pressed.
TABLE THREE: The lowest mathematical position (i.e. the highest on the screen) available in the Subitem linked list is "clow," and is selected if a SHIFTED UPARROW is pressed. In the special cases where an Item has Subitems, I chose to set one of 4 possible flags to note possible movement, rather than create another bunch of variables for right and left. The variable "stoir" is set if pressing the RIGHTARROW results in movement from a Subitem to an Item. The variable "itosr" is set if RIGHTARROW is a valid movement from an Item to a Subitem. As it's coded, the routine knows the difference
between Subitems placed to the left or right of the respective Item, making Menu movement less complicated.

Nacogdoches, TX 75961 Once the possible movements have been calculated, another switch case combination decides how a call to the SetNew- Position function will be made. The SNP function calculates where to place the mouse pointer. The parameters indicate the depth of the Header, Item, and Subitem of the entire Menu tree in the limited lists. Note how the use of defines makes reading easier. If not shifted, the mouse moves to the near item, but a
shifted keypress results in a move to an extreme position in the menu strip.
THE SNP FUNCTION The SNP function uses the characteristics of the menu structure to calculate where the mouse must move. Because some programs have Subitem lists that overlap more than half of the Item containing the Subitems, a temporary Event "tempEvent" was created for the linked list. Its function is to zip the mouse to the header, and to make Intuition remove the Subitem list, enabling the mouse to be properly placed on the next Menu Item as positioned by the "dum- myEvent" Event, ScaleX and ScaleY were needed to handle the various possible screen resolutions. Although the means of
determination (ScreenHeight 202 and ScreenWidth
322) are by no means the best, they do the job quite well.

items and moving to the extreme positions when the shift is
held with the cursor key.
BUGS The program is actually crash-free, but it does have one shortcoming. To make coding simpler for this example, left and right arrow key presses are assumed to be meaningful when moving along the header, and between Items and Subitems. Some application programs have "two-dimensional" menu structures, and this program may not find some of the possible items if they have the same TopEdge value. Since very few programs use this, the mouse can be used to move over to the unreachable items and a press of the Return key will still register the selection. This can be corrected by a more

Who knows, maybe we can even see those secret messages mentioned in Amazing Computing V2.8, without needing four fingers, two toes, and two noses (while inserting a disk in drive 0).
By the way, that program 1 mentioned at the start of the article that would make me rich and famous has long since been forgotten.

anyone can customize the Amiga to suit their needs. This
technique could be used in turn-key applications to easily
utilize the powerful Amiga Menu system, where a mouse is not
desired. Similar techniques can be used for answering
requesters or pressing gadgets. It beats the built-in method by
leaps and bounds.

NULL) C-0; Memory designed with some thought... If you’re an
Amiga 2000 owner, you'd undoubtedly like to add more memory to
your system. After all, the reason you chose the A2000 was for
the expandability. The question now is "What's the best path
for upgrading?". A 2 meg memory expansion card may seem the
cheapest way, hut it’s loo easily maxed out. You’d like to be
able to expand beyond 2 megs, but the sticker shock of an 8 meg
board populated with its minimum configuration of 2 megs makes
this route unappealing as well. The Digiironics RC4 Ramcard was
designed to solve these problems. The RC4 is auto-configurable
as low as 1 2 megabyte, but as your memory requirements
gradually grow, so can your memory, in steps of 1 2 meg, all
the way up to 4 full megabytes of no wail-stale fast memory!
If you’re an Amiga 500 owner, adding memory to your system may seem a bit more difficult than simply plugging in an expansion card. Some vendors seem to think it's a good idea to tear open your machine and solder in printed circuit boards, voiding your warranty, overheating the inside of the case, and bringing an already overtaxed A500 power supply to its knees. Digitronics offers a much better solution. The same RC4 Ramcard designed to plug into the A20IX) can be plugged into the expansion slot on the side of the A500 when installed in our adapter box. This adapter is a completely enclosed
low-profile metal case with its own power supply, which can fit neatly under your external A1010. This allows for a quick and easy way to add up to 4 megabytes of fast memory to your A500. Best of all, if you should ever decide to move up to an A2(H)(), the RC4 ramcard you’ve been using in your A500 can go along as well.
The RC4 comes completely assembled and tested, and is fully socketed for 4 megs of 256k x 4 DIF DRAMS (Ilk installed). Also included is a disk containing memory test software, our ow n version of a recoverable RAM Disk, and other useful utilities.

- -------- 'yF Hard n Fast You bought your Amiga because it is
the most powerful personal computer and installed a hard disk
to make it even more powerful. Being a knowledgable computer
user, you then set out to backup your data.
You started the program and waited . . . Through hours of gronking and disk swapping. It was so tiresome that you put off backing up your disk again, ff you haven’t already lost irreplaceable data, you know that it will happen sooner or later.
@%&C%! That’s how I feel too. 1 know the Amiga is better than that. Fortunately I know how to program the Amiga right.
Backup your whole disk, a directory, or just the files that have changed since your last backup. Restore it all or just a file or two that you fat-fingered. It’s fast, 10 megabytes in under a half hour! It's easy to use, with menus and all that nice Intuition stuff.

• AC* In a previous article I discussed the M2Amiga package's
termination code feature and its merits. I would like to
present termination modules for the Benchmark and TDI
compilers, and discuss their implementation.
Modula-2 Programming on the Amiga™ Termination modules for the Benchmark and TDI compilers by Steve Faiwiszewski Modula-2 programmers are quite familiar with the initialization code section of implementation modules. This code is guaranteed to run upon startup, before the main module gets a chance to execute. The initialization section enables the programmer to set up things specific to the implementation module without having to do so explicitly from the main module. This feature can make software a great deal more modular and "clean." Unfortunately, there is no analogous mechanism for
program shutdown, which forces the main module to "know" about any cleanup that must be done by the other modules, and to call those modules' cleanup procedures explicitly.
The M2Amiga package introduced the ability to specify for each module a procedure to be called upon program exit.
This frees the main (or any other "client") module from having to know about any cleanup details interna! To the implementation module, allowing the programmer to create truly reusable, stand-alone code. M2Amiga's implementation of this mechanism is quite elegant; upon the program's termination whether in the normal course of the program or due to some runtime error all the implementation modules' designated termination procedures arc executed.
This facility is especially useful on the Amiga, where any resource allocated by a task must be explicitly deallocated by it, or be lost forever. (Or at least until the next reboot.)
If your program is compiled with an Amiga compiler other than MlAmiga, and it encounters a runtime error and dies, all its open screens and windows will be left open, and its allocated memory will be lost.
Following M2Amiga's example, I set out to implement this termination feature for the Benchmark and the TDI compiler.
Specifying the terminating procedures is quite simple, as Modula-2 has procedure variables. Executing is another story. I could not find a way to have these routines implicitly execute upon normal program exit. Therefore, a program needing to use this feature must not exit at the bottom of its code or call HALT; it must call the procedure ExitGracefully. This is the only thing in my implementation that differs from the way M2Amiga does it (after all, theirs is integrated at the language implementation level while mine is done as user code).
To call the exit procedure upon encountering runtime errors, you must be able to trap these errors. The TDI package provides a very simple way to do so; Benchmark's approach is a bit more difficult. In the TDI package, there is a procedure variable in module AM1GAX called ErrorProces- sor which is called when runtime errors occur. To trap these errors, all I had to do was point ErrorProcessor to one of my own procedures. Since my goal was to call my own cleanup routines PLUS the usual code of Trapper and the Post Mortem Debugger, I simply saved the value of Er- rorProccssor in another
procedure variable first, then pointed ErrorProcessor to my own code. When an error occurs and the cleanup code runs, I simply call ErrorProcessor's old value (by actually calling the other procedure variable).
Since ExitGracefully must be the last procedure to run, it must not return (meaning that execution cannot just fall out the bottom of the procedure). Modula-2 provides the keyword HALT to terminate execution but unfortunately, the TDI package treats a HALT as a runtime error, so it cannot be used. Instead, the AmigaDOS Exit procedure is used. Exit returns control to the CLI, setting up the process's exit status according to the value passed to Exit as an argument.
Since the runtime package does not provide for it, trapping errors with the Benchmark package requires a bit more work. Each task on the Amiga has a field in its Task record, called tcTrapCode, that points to an error handler.
It's quite simple to point tcTrapCode to my own code. But since I still wanted to execute the error handling code of the Benchmark RuntimeErrors module, something more complicated was required.
When an exception occurs, the task's trap frame and the trap number are pushed onto the stack, and the error handler code is executed. (The exception I'm referring to is the Motorola definition of a runtime error. In Amiga lingo, a runtime error invokes a trap; an exception is something different.) The error handier must at least pop the trap number of the stack before executing an RTE (Return from Exception), Since I wanted to execute Benchmark's own error handler, 1 had to make sure the processor's stack was set up corTectly before the Benchmark error handler executed. For one thing, my
code can't simply call the error handler, as the compiler will generate a JSR (jump to subroutine) instruction which will alter the stack by pushing the return address onto it. Instead, I had to code an actual jump to the error handler using the INLINE statement.
The compiler always generates some instructions at the beginning of a procedure to push certain things on the stack, so I had to generate code to negate that. I found when absolute addressing is used, all the compiler generates is a LINK instruction (therefore, it generated more code when base-relative addressing the default was used).
Then all I had to do was code an UNLK instruction. LINK allocates a temporary area on the stack (called the stack frame), and UNLK deallocates it.
In the Benchmark package, a HALT is a perfectly acceptable event, so ExitGracefully uses it to exit the program. The status code is returned to the CLI by simply setting up the CLIReturnCode variable imported from module System.
The AmigaDOS Exit procedure should NOT be called. It will bypass Benchmark's own exit code, where libraries are closed and other cleanup is done.
Lastly, it's important to note, the Benchmark compiler defaults to having all runtime error checking disabled. I strongly urge you to always run with error checking enabled it can save hours of detective work. Error checking can be enabled using compiler switches, or it can be permanently enabled using the M2Init utility.

• Book reviews* by Richard Grace Learning C: Programming Graphics
On the Amiga and Atari ST By Marc Sugiyama & Christopher
Metcalfe Published by Compute! Books, $ 18.95 One of the books
about programming in the Amiga environment is Learning C:
Programming Graphics On the Amiga and Atari ST. Marc Sugiyama
and Chris Metcalfe have put together a volume introducing
reader to the C language in general, and specifically to C
programming on the Amiga and the Atari ST. The book includes
many large programs which must be typed in to create a custom
programming environment compatible with the book's concepts.
This approach has its problems. While the Amiga and Atari ST are both 68000-based machines, they are very different in their overall hardware structure. As a result, the actual programming tools available to programmers on the respective machines are different. The ST does not have the complex set of custom graphics chips (blitter, copper, etc.) or the extensive ROM kernel the Amiga does. The ST also does not have an equivalent of a CLI or even of the Intuition operating system. The Amiga's Exec task management kernel, which is the core of the multi-tasking system, also has no Atari ST
As a result, by trying to promote common ground between the two machines, this book completely ignores all these Amiga qualities. The closest the authors come to acknowledging this discrepancy is in the introduction: C Primer Plus, Revised Edition By Mitchell Waite, Stephen Praia, & Donald Martin Published by Howard W. Sams, $ 24.95 Inside The Amiga With C By John Thomas Berry Published by Howard W. Sams, $ 22.95 'The Amiga has a very complex set of screen-controller chips which fill areas, draw lines, and move images around the screen, giving the Amiga a speed advantage over the ST. The Amiga
does in hardware what the ST must do in software; leaving the Amiga's processor more time to do computing." This observation is accurate, but doesn't solve the problem.
Rather than presenting a useful synopsis and introduction to the Amiga Intuition and ROM Kernel environments (written in C), the authors substitute several graphics programs to fulfill the functions of line and polygon drawing, fills, windowing, etc. "in an effort to bring these two machines together." This approach is fine for the Atari, but the Amiga programmer is left out in the cold with no idea how many aspects of his powerful machine can be used.
Keystroking in a graphics routine is redundant for Amiga owners, when far more powerful manipulations can be found inside the machine.. This flaw is fatal, at least from the Amiga standpoint. Otherwise, the book is fairly well written. The aspects mentioned above are essential to understanding the Amiga. This book would certainly be more meaningful for the ST programmer, because Sugiyama and Metcalfe do a fairly good job of describing, in readable form, some of the often cryptic ins and outs of the C language.
The expertise the authors bring to this work is evident. The concept is flawed, however. It is hard to understand why the authors decided on their approach, given the differences between the machines. Amiga programmers interested in C would do well to stay away from this book because they will learn nothing about what really makes their machine tick.
There are superior alternatives, however. One is the C Primer Plus by Mitchell Waite, Stephen Prata, and Donald Martin. While it is in no way Amiga-specific, this book provides an excellent introduction and overview of
C. It is exceptionally readable, given the notorious tendency of
C specific books to be as cryptic as their subject matter. In
fact, it is tempting to call this text the best of its kind.
Any budding Amiga C programmer will profit handsomely from
this book.
(continued) Once familiar with the C language, the Amiga programmer is confronted with the onerous task of navigating the 2000 pages of Addison-Weslc s famous texts to understand the complex Amiga system. No longer.
Those books are still very useful, but John Thomas Berry's Inside The Amiga With C provides, for the first time, a useful, well-written, one-volume programmer's "roadmap" of the Amiga.
Berry aptly summarizes: 'The multiprocessing capability of the Amiga puts it in a class beyond most small computers. One important thing that experienced programmers miss when making the translation from mainframe or minicomputers to small systems is the ability to run more than one task at a time. From a productivity standpoint, the advantage is obvious."
Berry does not attempt to teach C programming; it is not his task. An exhaustive exposition of the ROM kernel is also beyond the scope of his work. However, he discusses many key ROM functions, gives a detailed account of Intuition (in one chapter!), and gives the reader the signposts and information necessary to acquire a comprehensive knowledge of the Amiga programmers, especially in C code, face a challenging task when they begin to explore the Amiga environment.
Amiga's numerous programming tools.
The chapter on Intuition alone covers almost a hundred pages and follows this logic: "Of the three programming environments found on the Amiga Intuition, AmigaDOS and the executive kernel this is the most difficult one in which to develop software. It is a very complex system which requires even small, simple programs to handle many display details. However, Intuition is meant to be the primary user operating system, and most software will have to deal with it."
The book is very well written and approachable by any intelligent user.
However, some prior knowledge of C is necessary (the more the better). For the Amiga C programmer this text is really the next logical step after C Primer Plus because it puts that earlier knowledge into the proper context.
Amiga programmers, especially in C code, face a challenging task when they begin to explore the Amiga environment. Fortunately The Waite Group, through Howard W. Sams publishing, has provided us with the means to make that task a little easier,

month 1 presented a program that set up and displayed a simple,
non-intuition screen. However, much remains to be explained in
our discussion of "display routines" on the Amiga Kernel.
Variations In Display You will recall from last month's discussion, ViewPorts may have special display properties of their own. Each ViewPort may have its own dimensions, color set, and display mode (resolution). Therefore, a display consisting of more than one ViewPort could have variations in display modes. For example, one half of the screen may be interlaced and hi-res with a set of 16 colors, while the other half may be low-res with only two colors. To accomplish this, the program must "link" the ViewPorts together so the display routines can process the entire display. The element of the
ViewPort structure titled "vp_Next" is a pointer to a linking ViewPort.
The order in which ViewPorts must be linked is related to the position of the ViewPort on the screen. For example, picture a two ViewPort display: one ViewPort on the top portion of the screen and one on the bottom. The ViewPort on the top must be the first in the linked list and must "point to" the second ViewPort (in the lower portion of the screen). Remember, the computer constructs the display from top to bottom. A list of ViewPorts must also be constructed this way. Each ViewPort may have its own display mode. The display modes, defined in the ViewPort element "vp Modes," are as
V. HIRES Set high resolution graphics mode (640 pfxels across).
V_LACE Set Interlace mode (4G0 pixels down).
V_HAM Set Hold-and-Modlfy mode (4096 colors of once).
V_SPRITES Include sprites (animation graphics objects) on screen.
V_DUALPF Set dual playfield mode (discussed later).
V_PFBA Set alternate priority of playfields (discussed later).
Modes can be combined by placing a "!" Between the modes. For example, to create a display with graphics of 640 x 400 pixels, the modes V HIRES and V_LACE must be combined, and the following definition is used: VJHIRES ! V_LACEc Since most of the work is done by the Amiga's display routines, creating variations in the display is rather simple.
However, one must remember the order in which the display routines should be called. I spent many hours trying to determine why some of the programs I wrote didn't work, and I found the fault in the way I set up the display. Here is the correct order:
1. Allocate memory space for bit-planes, use AllocRasterO.
2. Initialize the View structure with InitView().
3. Point the View structure to the first ViewPort in the linked
list. Set the View element v_ViewPort to the location of the
ViewPort structure.
4. Initialize the ViewPort structure(s) with InitVPort().
5. Link the ViewPort list if there is more than one ViewPort in
the View.
6. Point each Viewport to its own Raslnfo structure. Set the
ViewPort element vp_RasInfo to the location of the Raslnfo
7. Set width, height, and display mode of each ViewPort.
8. Initialize the BitMap structure with InitBitMapO.
9. Point the Raslnfo structure to the BitMap structure by setting
the Raslnfo element ri BitMap to the location of the BitMap.
10. Make the ViewPort by calling MakeVPortO. You need to "Make"
only the first ViewPort in the linked list, since the others
will be pointed to and included in the "Make" process.
11. Modify the Copper instruction set by merging the new Copper
display list with the currently existing list. Use the
MrgCopO instruction.
12. Show the display with the LoadViewO instruction.
Smooth Scrolling Smooth scrolling, a graphic effect used in many games to achieve a smooth moving background, is created by allowing the screen display to act as a "window" to a larger graphic area. The large display is shown only a portion at a time, the smooth scrolling effect is attained by moving this "window" to display other parts of the large display. What I call the "large display" is a bitmap of dimensions larger than the Viewport, the "window" is the ViewPcrt itself, which can display only a portion of the bitmap (see figure).
Each ViewPort has its own Raslnfo structure, pointed to by the vpRasInfo element of the ViewPort. The Raslnfo elements determine the position of the "window" in the large bitmap: ri_RxOffset and riRyOffset are the X and Y coordinates of the upper left corner of the Viewport in relation to the upper left corner of the bitmap. The smooth scrolling effect is attained by incrementing or decrementing the ri_RxOffset and ri_RyOffset values to move the position of the ViewPort in the large bitmap. After the Offset and RyOffset elements have been modified, the display must be recreated to give the
effect of motion. The following routines must be called in order to re-make the display: MakeVPortO MrgCopO LoadViewO Dual-Playfields Dual-playfield mode is a very interesting feature of the Amiga's graphics capabilities. In dual-playfield mode, you have two superimposed screens (playfields) to work with.
Each playfield can have a maximum of 8 colors. You must define the following structures for EACH playfield: Raslnfo, BitMap, and RastPort (for drawing routines).
Perhaps the most important structure in the definition of a dual-playfield display is the Raslnfo structure. For a dual- playfield display, you must create two Raslnfo structures one for each playfield. The Raslnfo structures must be linked together in the same manner that Viewports are linked: the element riJNext of the first Raslnfo structure should be set as a pointer to the second Raslnfo structure.
As in a single playfield display, each Raslnfo structure has its own BitMap. (An interesting effect in dual-playfield mode is the smooth-scrolling of each playfield at the same time, Two BitMap structures also must be defined, each pointed to by the Raslnfo structures, just as ir a single playfield display, the BitMaps may be of dimensions up to 1024 x 1024 pixels. When drawing in each playfield, you must address a RastPort structure for each. I simply name the RastPorts "rpl" and "rp2," for the first and second play- fields' RastPorts, respectively.
Because of the many ways of distributing bit-planes among each playfield, there are seven different ways to configure a dual-playfield display. The following table shows the assignment of bit-planes in dual-playfield mode: of Bit-planes Playfield 1 Depth Playfield 2 Depth 0 0 0 1 1 0 2 1 1 3 2 1 4 2 2 5 3 2 6 3 3 Another consideration you must make is the display priority of each playfield; in other words, which playfield will appear "on top of" the other. By default, the first playfield (playfield 1) will have priority over the second. However, this priority may be switched by setting the V
PFBA flag in the Viewport Modes. In any case, you must set the V_DUALPF flag in the ViewPort Modes to tell the system that this ViewPort will use dual-playfields. Follow these steps to create a dual-playfield display:
1. Set up a View structure.
2. Allocate memory for two BitMaps.
3. Set up two linked Raslnfo structures, each pointing to its own
4. Set up one ViewPort structure (both playfields will share the
same ViewPort).
5. Set the ViewPort element vp Raslnfo to point to the first
Raslnfo structure in the linked list.
6. Initialize each BitMap with InitBitMapO.
7. Initialize the ViewPort with FnitVPort().
8. Set the VJOUALPF and, if you want, the V_PFBA flags in the
ViewPort Modes.
9. Call MakeVPortO, MrgCopO, and LoadViewO.
Next month, I will present a program that sets up a dual- playfield display and smooth scrolls both playfields at once!
• AC- AMAZING REVIEWS CBTREE is a software development tool for C
programmers which provides a collection of C functions. They ¦
can be incorporated into your application program for quick
storage and retrieval of data records in your files. All source
code is included, making your code portable to other computers
where a C compiler is available, including PC-DOS and UNIX
systems. CBTREE can be used with any C compiler now available
for the Amiga.
What You Get The CBTREE package includes an interface to B+tree manipulation routines, sample programs which use the CBTREE routines to manipulate a database, a number of utility programs for creating and customizing your B+tree file structures, a user's manual, and free telephone support from Peacock Systems. Also included is a command file to install CBTREE on your system. All the documentation is provided on a single disk.
Background CBTREE provides an interface to routines which manipulate a B+tree.
Before describing the tools in this package, I will discuss some of the properties of B-trecs and B+trees, and the pros and cons of using such an access method. Three operations are normally performed on data records stored in a file. These are: FIND a record (given its key), INSERT a now record, and DELETE an existing record.
J, A sequential file is probably the easiest method of storing data. You simply place each record consecutively in a file. FINDing a record using a sequential file is easy, but slow, unless there's a small number of records. To find a particular record, we scan the file from beginning to end. We examine about half the records in the file. Given n records, we perform approximately n 2 operations. IN- SERTing records in a sequential file is simple. Position yourself at the end of the file and write the new record.
This is a single operation. However, to avoid duplicates, we first have to do a FIND to make sure the record does not exist, and then insert it.
DELETE can be implemented by FINDing the record and then marking it deleted (a single bit is sufficient for this) again roughly n 2 operations.
A B-tree is a data record indexing system which provides fast access to your data. Each of the operations in the elementary operation can be implemented in a B-tree, and performed with order log n disk accesses.
Refer to the table for the estimated number of file accesses required to retrieve data using a simple sequential file. Compare it to the number of file accesses using a B-tree index.
A B-tree stores your data in a balanced tree structure. Each node of the tree contains pointers to its children, as well as the key of the smallest element descendant from the second child.
The maximum number of children in a node is limited by the block size of the tree's nodes. All data records are stored at the leaves of the tree. (For more details on the internals of B- trees, see the description of 2-3 trees in Chapter 5 of Data Structures and Algorithms, by Aho, Hopcroft and Ullman, Addison-Wesley, 1983.)
Storing your data records, using B- trees or any other indexing scheme, does use more disk space than a sequential file, but the time saved by the indexing should be well worth the extra space.
A B+tree (yes, that's "B plus tree") is a variation of a B-tree with the index and the data are stored in separate disk files. The B+tree leaves (index file) contain actual pointers to the record location in the data file, instead of containing the actual data themselves, as in a B-trce. This organization allows for any number of separate (continued) indices into your data files, each in a different index file, and each representing alternate keys to access your data.
Installation CBTREE saves the programmer from implementing any B-tree functions. It allows the programmer to concentrate on all the application details. With CBTREE, you get the full power and speed of B+trees, without "getting your hands dirty" while implementing the low-level B+tree manipulation routines.
Installing CBTREE requires two formatted diskettes: one for the CBTREE library, and one for the program files. A command file for installing CBTREE is included on the distribution diskette. You may have to edit this file somewhat, depending on your particular programming environment, and also on which compiler you have. But the changes are quite straightforward.
Programming Before creating a database, you must set up the CBTREE parameter file btparms.btr. A utility called btsetup is provided as a programmer interface for creating and updating this file.
CBTREE allows you to change the parameters in btparms.btr using btsetup without recompiling your code. With this interface, you must provide the following information for each B+tree you are developing:
- Name of the index file
- Size of each index block
- Maximum key length
- Data record size Given the information in the parameter file,
your program must call the routine btrinitQ to initialize each
of the B+trees it will be using. It must also open all data and
index files. At this point, all further calls are made to the
roatine cbtree(). The operation performed is dictated by a
field you se: in a structure called btcommo. The user's manual
provides detailed examples of function calls for all CBTREE
operations. Your code must provide the user interface and
screen handling facilities for input and output, but CBTREE
will handle all the file I O.
Sample Programs CBTREE comes with a sample database and code for manipulating the package. The sample is a physician's database of patients, indexed by patient's name and Social Security number. It stores both B+tree indices in a single index file. A program (B.d2keys) is supplied to read the data records from a raw data file and create the corresponding data and index files.
In execution, this program took only about 45 seconds to build the database in RAM for 150 data records, but over 13 minutes for files on disk. Given the slow disk I O of AmigaDOS, such a di'ference is expected.
The CBTREE package includes a program for manipulating this sample database. The user is asked which operation he would like to perform, as well as its keys and data, if required.
The program then runs and displays the results. This program helps introduce CBTREE operations. Also included in the CBTREE package are programs for verifying the status of your B+trees and for timing your CETREE operations.
User's Manual The manual provided with version 2,30 of CBTREE is labelled version
2. 00. Differences between this release and the manual are
outlined in a separate document included in the package. The
manual is 75 pages of explanation and examples of CBTREE
function calls, as well as installation instructions. The
manual's only problem is that the installation section is
geared toward PC-DOS users.
Peacock Systems has provided a document on both disk and hard copy to help out Amiga users.
Future Releases Peacock Systems is currently planning to release CBTREE 3.00. They plan to offer a user-oriented query language and report generator to be sold as a separate product, which will work along with CBTREE. The query language and report generator will be priced comparably to CBTREE.
Peacock Systems' policy update for registered owners is releases within the same version are distributed free of charge, while upgrades to new versions are charged S10 to SI 2 to cover the manual's cost.
Summary CBTREE is an excellent product and a quality tool for the C programmer.
Getting familiar with the CBTREE function calls takes some time. But the manual provides detailed examples that fully outline what must be set up before each call is made, and how to make each function call. Overall, CBTREE is not hard to use and the time spent getting familiar with the product is well spent.

(703) 356-7029 703} 847-1743 The National Computer Graphics
Association (NCGA) show was held recently in Anaheim,
California, right next to Disneyland. (For anybody
interested in computer graphics, the NCGA show was better.)
Most of the products on display at the show were incredibly
expensive so much so that when people saw what the Amiga
could do, they had a hard time believing the price. Some
people were actually checking the wires, like in the Wang
ROOMERS by The Bandito Commodore had a booth filled with third-party developers displaying some of the best graphics products for the Amiga VideoScape, Sculpt and Animate 3D, Deluxe Productions, TV Text and TV Show, Pro Video Plus, Professional Page, Digi-View, and X- CAD. The only new item displayed was Digi-View 3.0 with overscan (and some other features promised as well).
Digi-View is a software upgrade that should be available by the time you read this.
Professional Page was attracting attention from Publish!, a magazine devoted to desktop publishing that usually concentrates on IBM and Macintosh products. A crew from Entertainment Tonight was filming various demos for a special report on desktop video (air time unknown as yet). A sign of the times: Apple employees at Commodore's booth, inspecting Amiga products with a close eye. Sure, you can do some of that stuff with a Mac 11 (some day), but at 3 or 4 times the price. There's a Mac II buyer born every minute, though.
No one expected any surprises at the Hanover Fair, the big computer show in Germany. But Irving Gould, CEO of Commodore, provided one he announced the Amiga 2500 and 3000, and even showed A2000 cases with those nameplates on them. The A2500 has a 68020 and the A3000 has a 68030. Throw in the new Fat Agnus chip and the revised Denise, and that's basically what they were. No word on price or availability, but the Bandito would expect the A250Q for the fall.
Oh, and while Commodore watchers were surprised by the announcement, Commodore employees were even more surprised. Seems that Gould hadn't mentioned to the Amiga product managers he would be making these announcements. In fact, while Gould was telling the world about these new Amigas, Commodore employees were telling exhibitors at the NCGA show that no announcements would be made about new Amigas. You just don't know who to believe, these days.
In the second quarter (probably in June), Commodore will introduce the A2024 monitor, a 1008 x 800 monochrome display for current Amigas.
The new monitor pulls some tricks with the standard Amiga chips to get its high resolution, dividing the screen up into four virtual areas. It will be great for desktop publishing, but you'll want to use large fonts the screen is 13 inches diagonally and 100 dpi, so standard Amiga fonts are tiny.
However, don't try any animation it would look pretty strange on this monitor.
New Amigas will add another resolution mode 640 x 400 non-interlaced.
Don't expect more colors until summer 1989, at least. When the next round of custom chips appear, the color resolution will probably be 15 bits per pixel, which the Bandito's slide rule says is just a hair over 32,000 colors. You'll get 256 colors out of this palette at once, and there may be a special HAM mode that allows all 32,000 colors on the screen at once. Oh, and new operating systems? Well, expect 1.3 this summer, and then 1.4 by ycar-end.
Then again, you may be running UNIX on your Amiga another nifty gimmick shown at the Hanover Fair.
The word on the wires is that some Amiga developers are secretly looking into "porting" their products to Macintosh and MS-DOS computers. Why?
Well, there's almost 2 million Macs out there (200,000 Mac II's) and perhaps 15 million MS-DOS machines, so the potential market is much bigger than the current Amiga market. The Bandito hears two theories from Amiga developers to explain their interest in Macintosh and MS-DOS.
One is that if you have a successful product on the Amiga, it's easier and more profitable to translate this sure hit to a bigger marketplace than it is to develop a new product. The other theory is that if the product didn't succeed in the Amiga marketplace, maybe it will do better when there are 4 or 30 times as many computers to sell it to (if you think this second theory sounds a bit funny, you're right).
Companies are working on IBM and Mac products under both theories. A word to the wise: the Amiga third- party market is full of garage entrepreneurs who started out by putting their product in a ziploc bag, and though (continued) 0 Distortion-free fills in raster lines crisp bright colors, converts all IFF files Wow- Custom graphic -int and illustration.

P. O. Box GGO, Cooper Station New York, N.Y. 1027G most Amiga
developers have gone beyond that, they're still not in the
weight class of Mac or IBM type companies, The companies in
those markets tend to have a LOT of money and some very clever
people. The big fish coming from the Amiga pond had better
watch out for the great white sharks... ...and the sharks are
already circling.
Takeover rumors are hovering around several developers. Companies that have created successful products have gotten big enough (or have the technology) to attract some of the heavy hitters in the computer business, where acquisition has been all the rage for the past year or so. The Bandito hears that Apple has supplied some Mac II's to certain developers to get them to develop their applications for Apple (and possibly for other reasons?). Dollars are beckoning, and it's a good bet that some companies will grab while the grabbin' is good.
You can tell the software business is doing well when companies arc hiring each other's employees. Electronic Arts, long notorious for taking the best employees away from other companies (usually Activision), is now seeing the cream of its crop skimmed off. The Bandito hears that more than a half- dozen EA employees have left for greener pastures (read higher salaries) at Activision. Not only that, EA seems to be the place to hire new marketing vice-presidents first NewTek, then Activision, and now Accolade have all acquired people from EA to become marketing Vps. Not to be outdone, EA has
hired Aegis' marketing VP, John Skeel, as a product manager for video and music products. 'Round and 'round they go, where they stop, nobody knows... 35mm SLIDES FROH VOUR ARTWORK!
The Bandito hopes some of these Amiga developers have been working hard, because we haven't seen much in the way of new products lately.
Delays are everywhere, and the RAM chip situation (availability tight, prices going through the roof) hasn't helped.
Memory expansion board prices are going up, and new products that depend on RAM chips may be delayed or see price increases. The Bandito th.nks the prices for the NewTek's Video Toaster, Mimetics' ReaSyn board, and Commodore's frame buffer board will all be higher than initially announced. Of course, in six months, the price of RAM chips should fall, and maybe the board makers will lower their prices (then again, maybe they won't). Hopefully, there will be a flood of products released at Comdex in May.
Whatever happened to Caligari?
Perhaps you remember the demo (first shown at Siggraph in 1986), with the "camera" flying through an Amiga logo floating in space, then zooming into and around a set of three- dimensional shapes. The display was tremendously impressive, but the product has never appeared. So the Bandito tapped into the electronic grapevine to find out the true story.
Seems that Electronic Arts picked up the rights some time ago, but Octree Software (the developer) has had problems keeping and finding programmers. The word is that the interface is good, but the rendering still leaves much to be desired (no ray- tracing), The development is taking so long that the product may well be obsolete by the time it gets to market.
You snooze, you lose, as the saying goes.
Is there a curse on low-cost genlocks?
First Commodore, now Mimetics has problems getting a reliable product at the low price point. The Bandito thinks someone should just put out a basic, reliable genlock at whatever it really costs, and not try to cut corners.
Digital Creation's SuperGen works well, but it has some extra features that not everyone needs, and it costs S750. How about a basic genlock for £300? No frills, no muss, no fuss, The Bandito's got his money ready any takers?
Commodore's new president, Max Toy, is trying hard to fix the problems he's inherited. He even has an assistant who asks questions of Commodore dealers, buyers, and developers in an effort to identify problem areas and suggest solutions, A laudable effort, since many of Commodore's problems can be solved just by listening to the people who actually use the products on a day-to- day basis. Let's do our part by trying to come up with constructive suggestions on how to make things work better. Meanwhile, the Bandito will do his part by continuing to talk about what's really happening in the
Amiga market, so everybody has enough information to make intelligent suggestions. Besides, gossip is so much fun, isn't it?

In the Public Domain by C.W. Flatte Announcing Fred Fish disks 129 to 138!
Fred Fish 129 DosJCttu'k version 2.0 (update to disk 103) Tired of those long, slow loads from floppies? Then put the pedal to metal with DosKwik, by Gary Kemper.
Comprised of the two programs ReadKwik and RitcKwik, DosKwik allows you to save and load files from floppies about 3 times faster than AmigaDOS. If that isn't enough, DosKwik allows you to save more data on a diskette than ever before - a whopping 901,080 bytes on one diskette. DosKwik also allows you to save massive files, that would normally only fit on a hard disk, on multiple diskettes (for that gigantic one and a half meg digitized sound file). You should note, however, that DosKwik does not store files in AmigaDOS format. DosKwik is available only in binary form, and is only accessible
through the CLI.
MRBackup versions 2.0 & 2.1 (update to disk 128) There's nothing worse than a hard drive crash... especially when there are no backups, MRBackup to the rescue.
This hard disk backup utility by Mark Rinfrt is flexible and time-saving. It backs up individual directories, directory trees, even a whole disk easily. Incremental backups, based on last modified dates, are also suported.
File compression is standard. It's no speed demon, but MRBackup is powerful and easy to use. Extensive documentation is included.
Version 2.0 includes the source.
Version 2.1 includes only the binary (the source is available from the author).
The virus is still alive and kicking... Get rid of it for good with VirusX, on Fred Fish 137!
Paintjet Attention PaintJet owners! This one's for you! Finally, an "official" Hewlett Packard PaintJet printer driver, received directly from Hewlett Packard and placed in the public domain. This one is snag-free! It has been fully tested by H-P on the A500, A1000, and A2000. Great printing and it doesn't cost fifty bucks!
(continued) Patch versions 13 & 2.0 Here's a useful program. The official definition of patch, from the Contents file: 'Two independent ports of the very useful Unix utility 'patch,' which applies context diffs to text files to automatically update them." Got it?
Just as the definition states, there are two independent ports of Patch included on this disk. Patch version 1.3 was ported to the Amiga by Rick Coupland, and Patch version 2.0 was ported by Johan Widen. Both versions include the source.
Fret! Fish 130 DirMaster version 1.1 (update to disk 108) If you're like me, you have anywhere from twenty to fifty diskettes scattered on your desk. You have another two hundred or more in a shoebox many of which aren't even labeled, which is another story. What is actually on those diskettes?
Catalog those disks with Greg Peters' Directory Master, the fastest, most comprehensive, and most versatile disk cataloguer available on the Amiga.
Functions include Finding Duplicates, Display Filtering, Powerful Sorting and much more. Directory Master is fully mouse and menu-driven, and can be run from the WorkBench. This is a superior product! To get you started, Directory Master also includes sample database files of the Amicus, MCA and BIX_28 Dec libraries. Now where is that printer driver 1 downloaded a few months ago? Cee, only two hundred disks to check. Arrhhhh!
Evo Did you ever wish you could watch the evolution of man from 20 million years B.C. to the present? Evo shows the path of human evolution over 20 million years. In fact, a total of 601 crania can be displayed by clicking on a specific era on a time-line. Clicking on the "text" option displays a paragraph about the species currently displayed. Evo is a wonderful product by Steve Bonner. Well done! Evo includes the source in C. By the way, did you know that man of 4 million years ago (Australopithecus afarensis) walked upright, was only about 4 feet tall, and had a brain of about 450cc
(vs. 1400cc for modem man)?
Hp version 1.0 Calculate those complex numbers with the Hp RPN scientific calculator by Steve Bonner. This exceptional calculator is designed to look and function like a hand-held scientific model. Hp supports calculations in binary, octal, decimal, hexidecimal, floating point, and complex numbers, Hp also includes 32 registers for storing data and transcendental functions. Includes the source in C. Let's see... 1-1=2.. .2+2=4... Mach version 1,6a MachClk version 1.2a Is your mouse just dragging along?
Need a little speed? Then turbocharge your mouse with Mach, the mouse accelerator. Available only through the CL!, Mach boosts the mouse by a variable acceleration factor (0-9). Mach also gives your Amiga mouse the capabilities of a Sun mouse the window the pointer is over becomes the active window. Also features the ability to program HotKeys (assign definitions to the function keys).
Other features include screen blanking, Cick-to-Front capability, and more.
The disk also includes MachClk, with all the features of Mach plus a title bar clock, beeper, and on-line meter. The title bar clock displays the available memory and the time. The beeper, when activated, will beep at set intervals (from 0 to 60 minutes). The ori-line meter keeps track of the time on-line and converts it into terms we can deal with much better than minutes dollars (from your pocket).
The rate is variable and can be easily set.
Mach MachClk is definitely a don't nr.ss! Another superior product by Polyglot software. (Includes the source to Mach 1.6a in C.) PatEdit Designing fill patterns for use with the Amiga SetAfPt macro call? Eliminate graph paper and design patterns up to 32 bits high with PatEdit, by Don Hyde. PatEdit is easy to use and makes full use of the Intuition interface. PatEd also supports the saving and loading of pattern files. The save function also creates a C header file which contains the code for the data which is required to pass to SetAfPt, SetAPcn, and SctBPen. PatEdit includes the source in
C. Qman Mandelbrot programs create beautiful graphics, but arc usually painstakingly slow. "Quick Mandelbrot" or Qman, by Steve Bonner, is a speedy mandol- brot-type program which is written partially in 68000 assembler code to speed things up. Qman is runable from the Workbench and makes full use of the Intuition interface. This program is great for people new to mandelbrots (it won't discourage them with slow results).
Wow! That's neat!
Well, that about covers the first two disks, and I’m out of time. However, one final note before I close: The virus is still alive and kicking... let’s get rid of it for good! There are a few CLI-based virus checkers available in the public domain, which do a great job in ridding the virus from your diskettes. But, what if even the mere thought of having to use the CLI is even worse to you than having the virus on ALL your disks?
The solution? VirusX, by Steve Tib- bett, which is available on Fred Fish
137. VirusX runs in the background and automatically checks all
inserted disks for a nonstandard boot sector.
These disks can optionally have their boot sector rewritten to remove the virus. More on this next month... Until then... Cotcha!
