NETWORKING The ocher day, during a telephone conversation, Geoff Evans at Commodore Business Machines in Canada happened to tell me about a new tool he was using in the office. It seems a British-based company called Hydra Systems had developed an Ethernet system for the Amiga called AMIGANET. Geoff was extremely proud of the way the system worked and how easy it was to install.
From The Managing Editor I was immediately interested. Foras long as we have been producing AC (four years now this is our anniversary issue), we have been looking for a networking solution on die Amiga. While there were networks available, few could do the tilings we wanted. When we told one company what we wanted to do, they suggested we adopt their system with a Sun workstation as a file controller. We were not interested.
While it might have seemed a workable solution to them, it was a dishonest solution for us.
AC maintains a policy of only utilizing software and hardware as it is shipped by the vendor. This means that we do not want a special piece of hardware which has been through more trouble-shooting procedures than an Amiga user would receive from a dealer. Nor do we want any more technical support dian we would expect to receive as an Amiga user.
As a result of this policy, misunderstandings sometimes result. When a developer is wholly enthusiastic about their product, and we tend to shun the extra assistance, the vendor can misinterpret our hands-free attitude as a lack of interest. But our main goal is to supply the reader with an accurate account of what they should expect when they purchase the product.
This means that our Amigas have had to rely on die tried and true method of file serving called "the floppy”. I will take this article I am typing on my Amiga 2000 and place it on a floppy. I can then throw it to a proof editor on the other side of our production area, where they in turn will place it in their Amiga for corrections. The efforts become more difficult if we want to use a printer or modem, which are connected to another Amiga. (During this issue, quite a line developed behind the editor who was printing out sheets from dte Amiga onto our Varityper VT6O0.)
Compounding this problem is the number of Amigas we use in editorial and production. Every editor, writer, or production person has an Amiga. Up till now, these units have been maintained as separate islands of computing. There were no bridges nor lines to tie them together.
EDITORIAL This is why we were so excited to hear of AMIGANET. On page 63, Ernest Viveiros, Jr. Previews this product by installing it in two of our Amiga 2000's. While this is not a review (we only received die product at press time), it is mentioned in this issue with exuberance. I promise, you will see a full review in a later issue.

For Am ga SCO. 1000 and 2000 systems wth 1VB Ternary. A ra'O O'Sk s recommenced Dear AC: I need a printer driver program for an Amiga 500 and a Star Gemini 10X, 9-pin, dot-matrix printer.
I have had the printer for approximately eight years and I just acquired the Amiga four weeks ago.
Although the printer works for one particular application (it prints scores from the World Class Leaderboard golf program), it does not work with the Amiga Workbench 'graphic dump’ for the 'notepad'. When I asked the dealer about this problem, he suggested that I needed a printer driver and gave me an issue of AC's Guide to the Commodore Amiga which listed all your Fred Fish programs.
However, I was not able to locate the disk I need. As I recall, when using that printer with my former C-64 and Cardco +G interface, it emulated an Epson printer.
Your assistance in this request would be greatly appreciated.
Sincerely, Terry L. Sassaman Reading, PA Well, do thank your dealer for us, Terry, they definitely had the right idea. The atiswer to your problem should be found on Amicus disk * 9. If you r dealer does not have this available they, or you, can order it directly from us. ED.
Dear AC: In my humble opinion AC is THE BEST. For content, the other magazines for the Amiga don’t come close. Keep up the good work; and more product reviews.
For those of you that use the B.A.D. disk optimizer (if you don’t, I strongly recommend it it’s well worth the 30 some dollars) I have a simple tip. I have been using this trick 011 my data disks: disks with files that are used exclusively by other programs such as MaxiPlan, Dpaint, etc.. If you usually open these files with the file requester from your main program, ‘BLITZ* these data disks using the “CLT option instead of tire "WBench" (default) option. You will find that when using the file requester for these disks after Blitzing them, the Directories, Sub-Directories, and files will fly
up on the screen, and without that annoying disk thrashing.
To go one step further, if you have die NOICON option when you save the file, use it. Or, after saving the File delete the .info file. This will not only save you space on your disk but also speed up optimizing die disk. Of course, when you delete the .info files, you won’t be able to open the file from Workbench. But since you normally open it within the program via the file requester, this won't matter.
For a long time I have reaped the benefits from tips provided by fellow Amigans through columns such as this.
And, even diough this is no earth- shattering tip, perhaps it will help to improve that quality time spent with your Amiga.
Fred Hayden Jr.
Huntersville, N.C. Thanks for the tip, Fred! We always appreciate fellow Amigans offering their hard-earned solutions to problems. It makes life easier for all ofus. Please keep up the good work and keep sending in those tips! ED.
Dear AC: Just a little tip for all the Breach 2 players out diere. I call it the multiple item use option. First select the item to use, I like the neutron bomb but you can use others, from die selection menu. When die new cursor appears, select the drop an item.
From diis menu drop die neutron bomb.
You can see the item appear in your square.
Now position the cursorwhere you want to dirow the bomb. Mega deadi at an affordable price! Now you can pick up the bomb and reuse it. This is nice for diose densely populated areas.
Tom Cafaro Bethel Park, PA Thanks for another great tip! ED.
Dear AC: In “View from die Inside: Bars and Pipes", Melissa Jordan Grey incorrecdy states die Bars and Pipes is “ the first object- oriented musical composition environment.’' This is very far from the truth. Object-oriented music languages have been around for a number of years.
IRCAM’s MIDI-LISP runs on die Mac.
Hierarchical Music Specification Language (HMSL) has been available for die Mac and the Amiga for at least three years now.
HMSL’s flexible object-oriented environment is based stylistically on Small talk, and is designed to facilitate experiments in music composition, form, and real-time performance.
This is not the first time that I've seen Bars and Pipes promoted as the firs t object- oriented music program. It is an incorrect statement, and should be dropped from their press releases. Incidentally, I do think Bars and Pipes sounds like an interesting package.
Yours, Nick Didkovsky New York City, NY We contacted Melissa Grey from Blue Ribbon Bakery fora comment. Apparently she feels that she might have left herselfopen for this criticism by calling Bars&Pipes an "object-oriented music environment" (continuedj UNLOCK THE GRAPHICS POWER OF YOUR AMIGA 2000!

Dear AC: I am one of the many Amiga 500 owners who bought their machines after Commodore started shipping the 1 meg Agnus chip with the A500. This, however, is not the blessing I first thought. I have come to find that even though I have 1 meg installed, the A500 is set at the factory for 512K of RAM and requires some internal modifications before the 1 Meg will be recognized as chip RAM. Like many AC readers I have enjoyed your hardware articles in the past and would like to make the modification myself. Will AC be publishing such an article in the near future?
Sincerely, Victor LoPresto Ft. Worth, TX To tell the truth, Victor, we've been plagued with questions about theA500 and the new Fat (Fatter) (Obese?) Agnus. Even our own Bandito is confused (see this month’s Roomers column). We had even been told by several knowledgeable (we assumed) sources that the new chip will not work in th e500's at all. Here’s the official wordfrom Commodore: Apparently, even after the introduction of the new Agnus, Commodore continued to put the older version in theA500 ’$ until supplies ran out.
They say that units currently being shipped (as well as all of those shipped since sometime before Thanksgiving) now include the new chip. They were notable to give us any information regarding lot or serial numbers to help identify your particular machine. You must still contact either your dealer or Commodore if you are unsure as to whether or not you do have the new Agnus chip. If you do have the new Agnus you will still need to move one jumper on the m oth erboa rd. This is a simple change to make and, although Commodore still recommends that you have your dealer do it, your dealer may
just tell you which one to move. There is, however, one more small fly in the ointment. It seems that this new Agnus will work with Commodore memory expansion units as well as with most third-party units but, apparently, there are a few it will not work with.
Commodore would not provide us with names, buttbey claim this is another case of some developers taking shortcuts or otherwise not adhering to all of the rules. If you 're about to make the plunge into 500 memory, you may want to get assurances from your dealer or the supplier that the particular memory you are contemplating will work with the chip. ED.
¦AC* New Products and Other Neat Stuff by Elizabeth G. Fedorzyn THE END OF WORLD AS WE KNOW FT New from Synthetic Reality Software comes World 3D, an interactive graphic editor for use with the shareware DBW_Render raytracer.
Written by Nathan Stone, World 3D provides speed in designing, editing, and previewing scenes for DBW_Render. Among its many features, Worid 3D allows you to save and create individual objects and construcy a library of commonly used shapes, easily edit attributes as well as textures and global parameters, and load and use VideoScape and Sculpt-3D objects. The Synthetic Reality program also sports ultra-fast Preview mode, compact code, editing via “ghosting", as well as object duplication and true 3D solid object support.
As demonstrated here, the results can be quite impressive. The included shot was created using World 3D and importing the lettering from Sculpt-3D, with the marble texturing being added afterwards. The image was calculated on the Amiga at 1024 x 1024 pixels.
World 3D runs on any Amiga and requires 1 Meg RAM. The program is compatible with DBW_Render, versions 1.0 and 2.x (the shareware program is included with the package), and sports a friendly “point and click" interface.

plumbers or would-be plumbers out there, it’s time to take
a swig of Drano and grab a fat roll of duct tape.
Originally created by John Dale and Martin Day in Bristol, England, Pipe Dream: The Fast-Flowing Game of Skill, Strategy, and Plumbing is now being released as a result of a collaboration between the British designers and Lucasfilm Games.
In Pipe Dream, your objective is to construct the longest possible continuous pipeline by piecing together various shapes of pipes that appear in random order you know, just like a real $ 35.00 hour plumber. All the while, you are racing against a stream of oozing chem ical fluid of dubious origin called "flooz".
In a slow-motion training period, you learn the skills necessary to face the flooz.
But it may take a considerable apprenticeship for you to advance through the 36 increasingly difficult levels. While Pipe Dream may begin on a basic training field- with seven basic pipe shapes, the game advances to more challenging levels filled with one-way pipes, obstacles, and faster- flowing flooz. Bonus rounds appear after players complete four levels.
Pipe Dream allows more dian one plumber to try their wrenching skills at one time. Two players can play against each other, or join forces in a joint battle against the flooz.
The Lucasfilm release also features a top ten high score table, and may be controlled using the keyboard, the joystick, or the mouse. A minimum 512K memory is required.

• AC* Las Vegas has got to be the perfect site for the Fall
Comdex. The similarity is really striking between the
atmosphere at the show and outside in the various casinos
around town. Both use glitter, glitz and sizzle to grab the
attention of people passing by. Both offer entertainment, food
and refreshments as an adjunct to their main business
activities. Finally both offer the potential for realizing big
winnings. For Comdex exhibitors a hit hardware or software
product can result in sales and profits in the millions of
dollars. For attendees time invested in listening to a sales
spiel or watching a demo can payoff in a promotional giveaway
ranging from a $ 50 software package to a complete system valued
in five figures.
IBM, Apple, Intel, Microsoft, Lotus, Toshiba, NEC etc. However for an Amiga dealer, distributor or end user the place to begin the show tour is obviously at the Commodore exhibit.
Unfortunately, the booth was not an impressive site. First of all it was located in the East Lobby, adjacent to the main show hall. There was only one other exhibit in the area (Tektronix), and hence it was not well sited to catch the interest of passersby.
Even worse it was located down some stairs away from die main traffic route through the lobby, so a conscious effort and a change of direction was required to enter the display.
The booth itself was a much scaled down version of the booth that had been new model but rather a variation on a theme. Like the 2500 the 2500 30 is basically a stock 2000 with an additional CPU in the form of a card for die coprocessor slot. The 2630 Accelerator Board consists of 25 Mhz. 68030 and 68882 math processors as well as an integrated memory management unit with a standarcl 2 megs of 100 nanosecond 32 bit RAM and space for an additional 2 megs of ram. Suggested list prices are S2195 for the 2630 and $ 1699 for the Amiga 2500 30.
Sharp-eyed readers will note that the list price for the 2500 30 is the same as that of tire old 2500. Concurrent with the release of the 2500 30 Commodore announced a series of price reductions ranging from 10 to 15% for the Amiga 2000 (52195 S 1895), by Ed Eercovits This year’s gathering of the computer industry was held from November 12th to 17th and was a record breaking event.
Nearly 1800 vendors hosted approximately 120,000 attendees with over 21 miles of aisles of exhibits in almost a million square feet of floor space in 10 sites.
It is a bit of a misnomer however, calling this an industry event. Comdex has evolved into a show primarily oriented towards personal computer hardware, software, peripherals and accessories.
More specifically Comdex is largely targeted towards the IBM PC and compatible community. Among these shades of blue, a Comdex attendee will find islands of vibrant and innovative colors, but they are usually few and far between.
ON THE SCENE Center ring at Comdex is located in the North and South Halls of the Las Vegas Convention Center. Here is where you will find the industry’s “household" names like used in Chicago at last spring’s Comdex.
Commodore continued the theme of focusing on the Amiga’s niche markets by setting up a warren of workstation booths dealing with desktop video, publishing, music and business applications (with the latter the area being shared between an Amiga and a Commodore PC). Along the top front of tire booth were five monitors simultaneously showing a video on the Amiga’s capabilities and first person interviews with various Amiga users recounting how they used tire Amiga.
COMMODORE GOLD While tire exterior may have been less than inspiring, there were a few treasures inside die exhibit in die form of new products from Commodore. The major announcement was a new member of the Amiga family-no not the proverbial Amiga 3000 whose appearance at Comdex had been rumored for weeks before the show. The Amiga 2500 30 is not really a 2500HD (S2999 S2699), 2500 20 ($ 4699 $ 3999) and die 2620 Accelerator card ($ 1995 51495).
Other new product announcements included the A2232, a seven port serial card ($ 399 suggested list) and the 2091-40, a 19 ms. 3-5 inch 40 meg hard card with socketed space onboard for 2 megs of 16 bit Ram ($ 899)- The A2232 uses 8 pin connectors connecting to industry standard DB-25 serial cables which are provided with the unit. With onboard ram and a dedicated microprocessor tire A2232 can operate all seven ports simultaneously at 19-2 kilobaud and multiple A2232 can be installed in an Amiga 2000, While the rated throughput is too slow to support Mididevices, die spec sheet supplied by
Commodore says it can be used to connect serial devices such as terminals (presumably for the Amiga Unix system), laser disc players (it has been rumored that a CD-Rom player is in the works with current speculation being that it will be released in 1990). And touch screen systems (a new marketing niche perhaps?).
The A2Q91-40 is based on die 2090A autobooting technology and is basically the Amiga 500’s A590 turned into a card for the
2000. In addition to being sold with a hard drive, it will also
be sold in a controller unpopulated memory7 version as the
A2091 with a suggested price of $ 399- All of the above
products were due to start shipping immediately after
Comdex.
The price reductions were also scheduled to take effect immediately with Commodore offering dealers price protection on existing inventories.
Hopefully this strategy will help move a lot of systems and peripherals and help Commodore reverse the losses of the two most recent fiscal quarters.
Conspicuous by dreir absence were several products which had been shown publicly at previous shows in the form of “technology previews". I was told that this was due to a new policy of not showing any products until they w7ere ready to ship.
There were several other new wares that were so close to being ready that the spec sheets were actually brought to Comdex, but at the last minute a decision was made not to announce them. Furthermore in the future product announcements would be grouped together and made on a worldwide basis, rather titan being released in dribs and drabs. So 1990 looks to be an interesting year with various unveilings taking place on roughly a quarterly basis.
In spite of the above, I was able to get a verbal update on a number of items. The Hedley high resolution monochrome monitor is now shipping in Europe and, with FCC certification almost completed, will be available in the US "real soon”. The Novell hardware, first shown at last spring's Comdex, is finished but the software is still being worked on by Oxxi under contract to Commodore. The Amiga Unix software will be based on AT&T's System V Release 4 and will be sold bundled w7ith a 68030 Amiga. In fact it had been demoed on the A2500 30 at a Unix Expo in New7 York a couple of weeks prior to
Comdex. The fact that Commodore is one of the first manufacturer’s showing a operating version of Release 4 should get Commodore off to a quick and hopefully successful start in the Unix market. The actual release date will be dependent on AT&T’s ‘'official” delivery of Release 4, which is expected by tire end of tire first quarter of 1990.
The timing of the unveiling of the Unix system is interesting in that it may very well be coincident with tire announcement of tire mythical Amiga 3000. Not much publicly was being said about the latter.
Given Commodore’s past track record my guess is that the official unveiling will take place at Cebit in Germany in March.
ON THE SIDE Not all the action at Comdex takes place on the exhibit floor. Throughout tire five days of the show there is a very extensive series of plenary sessions, seminars and panel discussions on various aspects of industry. Traditionally Commodore has been included in at least one of these presentations. During Spring Comdex in 1988 they were matched against Atari in a seminar on “Alternative Niche Markets". For the last few7 Comdexes they have been included, along with Apple, in seminars on various facets of multimedia, and at this show they were joined by IBM in a discussion on
“Multimedia Computing and Presentations".
Multimedia is becoming one of the hot new themes in the personal computer industry especially since companies like IBM, Microsoft and Intel have started embracing it as a “wave of the future”.
There is increasing interest in tire multimedia concept of integrating video, animation, graphics and sound as evidenced by the fact that attendance at the The Compugraphic rep gave me a press release announcing the licensing agreementfor incorporating Intellifont into Workbench. This teas rather exciting neivs, since it will give the Amiga state- of-the-art high speed and high quality screen and printer type intergrated at the operating system level above seminar had grown several-fold to over 500 people as compared to tire same seminar at the Spring Comdex.
Unfortunately Commodore's performance in the seminar was, at least in my opinion, second to dial of Apple, who had a very polished and varied presentation. Apple mentioned and demonstrated various multimedia hardware and software products (including ironically Sculpt 3D) and gave concrete examples of how Mac multimedia was being used in major US corporations. Dave Archambault from Commodore concentrated on the Amiga's technical specifications and cost benefits. It wras the classic confrontation between high price but available and useable products versus great potential and low price but more
limitations as far as current usability7.
THE GOODS Leaving tire Commodore booth, I headed out to see the rest of the show7 and to try and uncover news and information that might be of interest to Amiga owners.
Not too far away in tire Main Hall in the Sharp booth I discovered a 2000 being operated by ASDG in their demonstration of their new Scanlab 100. This is their latest addition to their line of col our scanners and software, but at a list price $ 995 it is much more affordable to die average user. The Scanlab 100 is based on the Sharp JX-100 hand scanner. Unlike other hand scanner's this one doesn’t require you to move the scanner over the document. You simply lay the hard copy on your desk and place the
4. 5 pound, 6.5" by 12.5" and 1.5" scanner on top of it. There is
a 3.9" by 6.3" window on the top of the scanner which lets you
view the area you are scanning to ensure that it is aligned
correctly. A scan at its maximum resolution 200 dots per inch
will take 40 seconds for black and white and 150 seconds for
full colour. Although the software can handle full 24 bitplane
or 16 million colour images, the hardware colour resolution is
limited to IS bitplanes or 256,000 colours. Due to the Amiga’s
video limitations not all the colours are displayable
onscreen. ASDG has developed a new screen format which they
are calling Ares and which uses 4096 colours on a high
resolution screen.
Formats with the same capabilities have been developed recently in the publicdomain (SHAM or sliced HAM) and by Newtek for Digiview 4.0. Although all these formats have the same colour resolution specifications, the image files are not interchangeable between applications. ASDG is interested in seeing a new standard emerge which could be universally supported.
A bit further over in the Main Hall Michtron was showing their new 9600 baud Group III external fax modem and software. It was scheduled to go on sale by mid-December at a suggested list price of $ 595. This is a fully multitasking system MICHIGAN SOFTWARE 43345 Grand River Novi, MI 48050 AUTHORIZED AMIGA DEALER

Allowing background receiving or transmission according to a user defined scheduled log. To prepare a document for faxing you simply print it to disk using the Epson printer driver. Received faxes are viewable in various magnifications on an interlaced screen using a zoom feature. The received fax is Stored in a proprietary format, but they are developing a program diat will convert them to IFF format. What really impressed me was the ability to take any IFF standard image or brush created in a paint program and merge it with standard text trom an ordinary' word processor for transmission, so
as to give the appearance of a document printed on a letterhead.
Undoubtedly there will be similar products appearing from other vendors, but Michtron has produced a very impressive product at a reasonable price as die first entry in the Amiga fax market.
TOUCHY SUBJECT Also on display in Michtron’s boodi was an interactive video display system from Future Touch. These are Amiga based systems housed in a “kiosk1 measuring approximately 2 feet by 2 feet by 4 feet high using a touch screen for user input. Typical uses for such systems are for public information booths, directories and product catalogs, point of sale terminals, computer based training, executive information workstations etc. Various configurations are available ranging from a budget system based on an Amiga 500 with 20 meg hard disk right up to a deluxe system which uses an Amiga
2000HD, Neriki genlock, Microway Flicker Fixer, Pioneer Laser disk, expanded ram, stereo amplifier and multiple comm ports! Prices for complete systems range from S4600 to 512,500. Future Touch also offers prefitted 13 and 19 inch monitors with touchscreen capabilities for 51100 and S3400 as well as a $ 800 hardware and software retrofitting kit for existing monitors. This type of hardware platform is an ideal solution for using an interactive application like those developed with Michtron’s Viva video authoring system.
Later getting back into the mainstream of the show I dropped in at the Agfa- Compugraphic booth to discuss the use of dieir fonts in the recently released Professional Page 1.3. I also wanted to check out the rumour that I had heard dial the scaleable font system for AmigaDos that Commodore announced at the Developers’ Conference in June was in fact the Compugraphic Intellifont technology.
The Compugraphic representative was quite open on this subject and even gave me a press release announcing the licensing agreement for incorporating Intellifont into Workbench. This was rather exciting news since it will give the Amiga state-of-the-art high speed and high quality screen and printer type (for both dot matrix and laser printers) integrated at the operating system level. Current progress on incorporating the Intellifont system in AmigaDos 1.4 is proceeding smoothly, and if the latter is released in early spring as is speculated, the Amiga will be tire first major personal
computer system to have a fully integrated scaleable font system. Support will be provided for die standard set of 35 typefaces found in most Postscript printers (possibly as a bundle included with AmigaDos 1.4; although a decision has not been made on this as yet). Approximate]}’ 100 additional typefaces will be made avail able for separate purchase a t about the same time as the release of 1.4, and Compugraphic will continue working at porting over many of the additional 1700 typefaces available in their font library.
I-iewlett-Packard has also announced that dtey will include intellifont support into their printer controllers for Level 5 of PCL (Printer Control Language) in the next generation of heir laser printers.
Compugraphic has also decided to make Gold Disk die exclusive distribution channel for the sale of Amiga Intel 1 i fonts for at least die initial year after release.
I decided to drop in on a couple of companies whose hardware products had impressed me during last spring's Comdex.
Zoom Telephonies has a product which they call the "Zoom EX Voice Data Telephone Network Interface”. In spite of its less dian catchy name this external, dual phone line, modem like external device does almost everything but make toast.
Tech specs include an 8 bit CPU, onboard ram and eproms, digital to analog converters (and vice versa), internal 2400 baud modem and jacks for headsets, speakers, audio I O, digital I O, parallel port as well as the standard RJ-11 and RS- 232 connections. It can be used as a voice mail system, a call forwarding device, a personal PBX, an automatic modem fax voice line switcher, incoming and outgoing cali logging and recording device and a telemarketing system. It also has its own C like command language which can produce compiled programs for loading into onboard ram or eproms for additional
user customization. I thought a Zoom EX with the Amiga's multitasking, speech synthesis and sound capabilities would make a powerful combination. Apparently so did a number of Amiga software vendors who have contacted Zoom and are working with them on various Amiga products at a very’ reasonable price given Zoom’s pricing of $ 300 or less to value added resellers. Look for some interesting product announcements in the near future.
Advanced Gravis had an Amiga in their booth demonstrating their high quality programmable Mousestick, With a 1200 line resolution it functions as both a replacement mouse as well as a digital joystick. They were also showing their new Hardpac line of self-contained external SCSI harddrives. The 2 pound Hardpacs are about the size of a paperback book, and are available in 20, 30, 40, 80 and 105 meg formats with a data transfer rate of 19 msec, and a 64K programmable disk cache. With an injection molded casing and, special shock mountings and automatic head parking, diese drives are designed to
be very portable.
Another company that was showing off an alternative input device for the Amiga was Marconi which was featuring their three button trackball which they are calling the Marcus. It has been a very popular in Europe and is now being distributed in the U.S. through Soudiem Technology' and MicroPace at a suggested list price of $ 87. Besides producing external, standalone trackballs, Marconi also makes a trackball module which is designed to be incorporated into keyboards. While I was in their booth, the Marconi representative mentioned that Commodore had purchased a number of these keyboard
trackball modules. I don’t know what type of prototypes Commodore's R & D engineer's are developing, but this little piece of news is certainly food for the imagination.

While a lot of the new hardware being shown at Comdex consists of MS- Dos compatibles and accessories, there is also a fair amount of “generic" products that are of interest to Amiga owners in particular. A number of companies including Hitachi, NEC and Panasonic were showing new colour postscript and video printers. Based on laser and thermal ink technology these machines can produce a huge palette of vibrant colours.
While prices are decreasing, they are still expensive at approximately 510,000.
However the obvious industry interest in the area of colour output devices means we should see some interesting developments in this area over the next two years.
Video is also starting to catch on in the MS-Dos world with a number of companies showing genlocks and still frame digitizers. Prices are still high as compared to equivalent .Amiga products, but this situation will change with Microsoft, Intel and IBM promoting interactive video as the new frontier for computing in the 1990s. At Comdex there were demonstrations of add-on boards with the capability' of taking a video signal and digiczing it in real time in a 256 colour, resizeable and movable window. A single frame can be grabbed with a click of the mouse and automatically copied to tire
Microsoft Windows clipboard for pasting into another application. While they are priced at almost the cost of an Amiga 2000 with a hard disk, they are available; there is nothing currently shipping or even announced for the Amiga that matches diese capabilities or ease of use, in spite of the Amiga’s supposed lead in computer video.

NEW TRENDS Mass storage is another sector where a lot of innovations seemed to be taking place. CD-ROM may finally take off after an announcement by Headstart Computers (formerly called Vendex but renamed after it was bought by Philips) of a new line of MS-DOS computers which come with CD- ROM drives as standard equipment. That it itself was not significant, but the fact that the base model includes a 40 meg hard disk, VGA colour, stereo sound, headphones, plus a mouse as well as half a dozen bundled CD-ROMs filled with applications such as Grolier’s Encyclopedia, Microsoft Bookshelf,
wordprocessor, spreadsheet, database, desktop publishing, VGA paint programs, commercial hard disk and operating system utilities and 30 games from companies such as Timew'orks, Electronic Arts, Mindscape and Ashton- Tate...with the complete bundle of hardware and software having a SUGGESTED retail price of under $ 2000! These systems could provide some serious competition for the Amiga in tire battle for the home computer market. If Commodore does release dieir rumoured CD-ROM drive they would be well advised to emulate Headstart initiatives and to form a mutually beneficial alliance with some
Amiga software publishers to help build the CD-ROM software base.
Optical media is slowly starting to make inroads into mainstream mass storage. ICI was featuring prototypes of new systems based on digital paper. This technology uses the same principles as traditional rigid opto-magnetic disks but instead uses a flexible recording medium to give storage capacities of up to 2.2 terabytes on a tape or 500 megabytes on a disk (the latter system is currently being developed by Bernoulli). The medium is “write once” but it is priced at an inexpensive enough a level that it can be used like paper hence the name "digital paper". XYX1S was one of the newer companies
showing an erasable optical drive. .Although their current SCSI-based models are designed for the IBM and Mac markets, I found out that they are working, in partnership with Impulse Ltd., on a erasable optical for die Amiga market.
Their other equivalent models are priced at $ 4998, which is not cheap, but if you're looking for a drive with a replaceable 600 meg storage capacity and a 60 millisecond access time, dien XY7CIS may have a solution for you.
For Amiga owners widi more ordinary sized wallets, several companies were showing floptical drives which should be going on Ure market in die first half of 1990. These look like ordinary 3-5 inch drives anddiey are can use normal 3.5 inch disks. However they can additionally read specially pre-formatted disks which have guidance tracks burned by lasers onto die disk surface. These guidance tracks provide very precise disk head positioning thereby allowing each track to be much narrower and hence more tracks to be recorded on die disk, so diat storage capacities of 20 to 50 megs can be
achieved. Since they use a SCSI interface, Always wished you could have a complete set of Amazing ¦ Computing-going back to the premiere issue?

They should be relatively easy to incorporate into the Amiga. According to Insite Systems, one of the major manufacturers of these drives, suggested retail prices should be about $ 600 for the drive and $ 30 to $ 15 per disk. Syquest was also showing some new removable hard disk subsystems with a new 3,5 form factor 42 meg model and a whopping 175 meg
5. 25 inch model. Both these substems are only 1 inch high and
feature an access time of 19 milliseconds. They are due to
ship in the second quarter of 1990 with pricing being very
competitve with their current removable sub-systems.
FUN & GAMES While Comdex is a very business oriented tradeshow a number of game companies are on hand to show off their new and planned titles. For the Amiga gameplayer the pickings were pretty slim.
Microprose Medalist was featuring X-Men: Madness in Murderworld, RVG Honda (Formula One motorcycle racing), Stunt Track Racer, Rick Dangerous, Weird Dreams, Xenophobe and Pirates (mid-
1990) . Microdeal newest release is Bermuda Project! An adventure
game set in the Triangle of the same name. Capcom USA new
product lineup included Pocket Rockets (another motorcycle
racing simulation), Forgotten Worlds, Street Fighter, Tiger
Road and 1943-Battle of Midway (2nd quarter 1990). Taito
was announcing a couple of aerial action games, Skyshark
and P-40: Tiger Shark for December releases with Chase HQ,
Operation Thunderbolt and the European game hit, the New
Zealand Story all being scheduled for the first half of
1990.
Major announcements as many people had expected. Commodore’s profile at die show was very low to die extent diat it was questionable whether the benefits gained were worth die costs of attending. In dieir defence it should be noted diat there have been major changes at Commodore over the last six months which undoubtedly affected their ability to put on a better showing. Hopefully however their performance at future Comdexes will be more impressive from the perspective of the Amiga dealer developer and user communities as well as within die context of die personal computer industry.
One sign of the success of the Amiga is when Far Eastern companies start producing peripherals specifically aimed at die Amiga market. Two Hong Kong companies, Asia Commercial Co. And Roctec Electronics Ltd. (marketed in the
U. S. under the California Access label) were at Comdex showing
off their Amiga
3. 5 and 5.25 inch floppy drives. Roctec also announced a new
A501 memory expansion clone as well as a 360k 880K 40 80
track 5.25 inch Amiga floppy drive.
Well that about wraps up the news from Comdex. While there were items of interest for Amiga owners, there were no

242 A Beginner's Guide To by John Steiner On The Amiga
Desktop publishing applications have brought people into
die computer age. In vast numbers. Basically, this is
because personal computers linked to laser printers have
the ability' to produce near typeset quality output. The
Amiga is more than capable at tasks associated widi
desktop publishing. Desktop publishing software triads
available for the Amiga has a wide range of capabilities
for a wide range of publishing needs. Xfhether your
publishing needs are as simple as a quarterly users group
newsletter, or as complex as a monthly, fuH-colos, glossy
magazine, Amiga desktop publishing cools are available to
help yougetthe job done.
Many people are confused about the difference between word processing and desktop publishing. Originally,word processors were used to replace the typewriter, and they did so with lower quality considering die capabilities of early personal printers. High quality' printing devices and more powerful softwaxchaye madeword: processing more powerful, more Capable and much more attractive, thus ensuring a permanent place for computers in the business office.. DTP VS. WP A desktop publishing program is not designed to be, and in most cases, is not very powerful as a word processing program.
The major function of a desktop publishing program is taking text (thatWas previously created in a word processor): and graphics (that were previously created Ln a graphics or paint program) and seamlessly integrating them into a single, cohesive document. The. Desktop publishing pro- ; gram usually forgoes Strong text editing tools in favor of better quality layout and page design tools. The fine line that separates the: two categories is becoming blurry as word processing programs add features that have previously been found only in desktop publishing programs. Further con-
fusiondevelops as competition in tire desktop publishing market is driving program developers to add powerful word process mg features such as spell checking and index generation.
This article is not written with any one desktop publishing program in mind.
Instead, die layout and design ideas expressed here are designed to improve the : appearance of your documents* w-ithout regard to die particular desktop publishing program you may use. All of the ideas : and techniques you will see here may be |: implemented on virtually ail Amiga based desktop publishing programs. Even if you don’t have desktop publishing software, yop may be able to use your w'ord processor to implement many of diese concepts.
• Consider my suggestions as rccommcnda- tions, not as absolute
requirements, when you plan your next desktop publishing
project. .
This article is divided into tliree parts. Several page layouts and design techniques are showm which have been proven to make documents look attractive to die reader. Type selection considerations are suggested to help you to choose :appropriate fonts for the style of document you are producing. Graphic elements can enhance the readability of your Figure One Portrait (left) vs. Landscape Orientation, Landscape orientation is often used for documents with large amounts of charts or graphs that are best displayed in a horizontalformat, documents by making your pages appear more
interesting and inviting to die reader.
PAGE LAYOUT AND DESIGN TECHNIQUES Before you begin your desktop publishing project, think about the nature of die document. Like a builder who draws plans before beginning a construction project, you should think about and “draw plans’’ before you begin construction on your pages. Start your document by designing a “page grid” layout, and if the document is a periodical, use the grid every time you do a new issue.
The page grid should remain the same throughout the document, as it creates an overall “look and feel” to die publication.
Changes to the master page grid should be die exception, and should be reserved for die page that has a special side bar story7, or unusual illustration. Even if you are doing a series of one page documents, the repetitive use of a similar grid for each page invites the reader in to visit familiar surroundings.
The page grid is composed of several easily recognizable page elements including margin settings, the number of columns, and column and gutter width (The gutter is the white space between columns.) Other components of the page grid include elements such as page format and page size.
The page format is suggested by the type of information to be presented. The two terms that are most often used to describe page format are portrait and landscape. Portrait orientation is used more often, but landscape setting is used for documents that contain large numbers of horizontal charts, tables or other horizontal data. See Figure One.
The first step in setting up a page grid is to decide how big each page is going to be.
Below are some facts that may help you choose a page size.
The two most common page sizes for multiple page documents are 8.5 in. X 11 in.
(letter size) and 5.5 in. X 8.5 in. (half-size).
Otirer common sizes are 8.5 in. X 14 in.
Figure Two Several commonly found page layouts.
Use an imaginary series of horizontal lines to divide the pages into thirds or fifths for inserting graphics or photographs.
Figure Four Use drop shadows to help guide the reader to the caption.

(legal) and 11 in. X 17 in. The latter size is often used to print four 8.5 in. X 11 in. Pages (using bodi sides of one sheet two pages per side). The sheet is then folded in half and becomes a four page tabloid Letter size can:
• fit more information on a page than half- size pages.
• utilize added white space to provide a more “open" look.
• make some jobs easier as it is standard for printing and
duplication.
Half-page size is:
• more compact, therefore less intimidating to the reader.
• easier to use and reference, because of its small size.
• easy to place two half size pages each side of a single 8.5x11
in. Sheet of paper.
Avoid unusual page sizes as deviations from standard sizes will cause your printing bill to be excessive. This is due to die waste generated by printing on larger sheets which have to be cut to the correct size. Excess paper ends up being discarded. If you need a smaller size, work in sizes that are evenly divisible into a normal page size (half page, quarter page, eighth page, etc.) The page grid also consists of vertical boxes, called columns that will contain die text of your publication. As a general rule, plan for about 50 to 65 characters per line when defining the width of a column.
If the line length is longer than this, it may be difficult to find the start of each line after reading the previous line. If die line lengdi is much shorter, diere maybe too many hyphens generated, reducing the readability of the document. Consider the font-related characteristics of line spacing, type size and style, and page size when determining column width. The use of a specific font, style and size will have a large effect upon die desired column widdi. See Figure Two.
Several examples of multiple column formats are shown in the illustrations. Use these as a starting point, and don’t forget to take a critical look at the publications you read regularly. Think about what makes their pages look attractive to you, and try to incorporate diose characteristics into your own documents. If your desktop publishing program comes with professionally done style sheets or templates, try using them as examples for your own documents.
The white space between columns is known as die gutter. The gutter helps keep the reader’s eyes on the correct column as die text is being read. A vertical rule (a thin vertical line) separating the gutters allows the gutter width to be smaller, as the rule helps keep die eyes from straying into the wrong column. One rule about gutter width to keep in mind is that it is generally considered unattractive to have different gutter widths on the same page when using multiple columns.
SELECTING TYPE Since before die invention of movable type for your document, the publishing industry has been conscious of die appearance of the letters as presented on the page. Any printed character has a mixture of the following characteristics: The shape and general appearance of characters is called a font, or typeface. Examples of fonts include Times, Helvetica, New Century, etc. Tire thickness and slant of the lines creating each character is called the lypes- tyle or, simply, style. The most commonly used typestyles are normal, bold, italic, and bold italic.
The size of each letter in the font can be measured in several ways. Fonts are usually measured in “points”, and a point is 1 72 of an inch. Normal newspaper type varies between 9 and 11 points. A 36 point headline is approximately 1 2 inch tall.
'The selection of an attractive font for your document should be one of the overall design considerations. Here are some general rules regarding font selection.
Fonts are either serif or sans-serif. A serif is a "tail" at the end of each pan of a letter. Serif fonts are easier to read in smaller type sizes, such as the body text found in most documents. Sans-serif fonts are cleaner and more modem looking, however they tend to be harder to read, especially in smaller sizes. A common practice among page designers is to use a serif font for headlines and a serif font for body text, Figure Five Symmetrical and asymmetrical pages.
Don’t fall prey to the novice desktop publisher's number one sin. Use only a minimum number of different fonts. Excessive use of different fonts makes your documents look unattractive, and gives it a "kidnap note" appearance.
Use fonts consistendy. For example, if you choose an Avant Garde font for heads and sub-heads, you should use dial font diroughout die document. Mixing fonts, sizes and styles excessively causes confusion for the reader as to wrhat is being emphasized on the page.
Combine typestyles (bold, italic, etc.) and point sizes to create the variety that documents need to help maintain reader interest. Designers attempt to make effective use of typestyles by following several general guidelines.
As with the use of fonts, use typestyles consistendy. Use typestyles for emphasis. Think of bold as a shout, italics for stress, and bold italics for urgency. Excessive use of typestyles other than normal reduces die impact of your message. Use the following guidelines to determine when to use which type sizes. Make body copy 8 to 12 points.
Make subheads the same size to a few points larger than body copy. Main headlines can be 14 to 20 points. Cover page text can be 24 to 48 points. Captions, headers and footers are usually the same size or slightly smaller than the body copy. Here are some general guidelines on text handling. A combination of upper and lower case text enhances readability. Use all capitals sparingly. Reverse text can draw attention to important information. Like bold and italics, excessive use of most special effects is counterproductive.
Use graphics elements to make your documents more interesting. The use of ruling lines, text boxes, illustrations, chans and tables all enhance the reader's retention of your message.
Use riding lines or "rules” to separate and organize subject matter, keep die reader's eyes on the correct column, and add visual interest to the white space in your documents. As with most desktop publishing tools, don’t overuse rules. They can make your document look disjointed and give the appearance that the columns of text have no relation to each other.
Be consistent with die use of rules. If a 3 point wide rule is used at the top of the page, make sure all pages with diat rule use die same 3 point specification. Use thicker rules to subdivide headings, thinner rules to organize sub-headings. Make the rules enhance your presentation without calling attention to themselves. A ruling box is used when you want the reader to notice important information such as disclaimers, cautions and warnings.
Ruling boxes also often surround the "side bar". A side bar usually includes information which highlights or illustrates the major topic of the body copy. Drop shadows help to set boxes off from the body text. The Tills Is an example ofnn a typical pull quote. W This is an example of a typical pu(( quote.
Figure Six Pull quotes can help break up large amounts of text in your publications.
This Is an example of a typical pull quote.
K S This is an example of a typical pull quote.
Position of the drop shadow will help guide the reader's eye to the caption. Therefore captions should be placed opposite die drop shadow. Drop shadows are best reserved for smaller boxes. Large boxes can be more effectively set off from die normal text by position and by the use of rules. See Figure Four.
Use symmetry and asymmetry to your advantage when placing graphics and text boxes on the page. The choice between them can have a tremendous effect on the overall Tfie1Ten Commandments for Desktop (Publishers

In general, a symmetrical design is less dynamic in appearance and tends to be less visually interesting than asymmetric as the examples in Figure Five demonstrate.
Asymmetric pages can look jumbled and disorganized, however, unless plans are made to keep the page visually organized. In any case, when you are working on multiple-page documents, never mix the two styles within die same document. The result is visual confusion for die reader.
Don’t be afraid of white space on the page. Instead of trying to find something to fill it, try to position the space opposite a graphic, or as a buffer between two stories.
If you’ve got more white space than you can use, and don't have an appropriate graphic or visual element to place in the document, use a "pull quote". A pull quote is an often used tool of the newsletter editor to stretch an article to finish filling a given column. Making a pull quote is easy. First, prepare a place for text that will, -when pi aced in the middle of a column, allow the text in the last column to flow to the bottom of the column without going into a new' column. Then find an appropriate quotation from the article that makes a cogent or controversial point about the topic,
and copy that quote into the space reserved for it.
Change the typestyle and font to match a commonly used headline or subhead in the docu ment. Final ly consider whether or not the pull quote should be set off from the article by rules or a shadow box. See Figure Six.
Desktop publishing can make your printed documents more readable and more able to achieve their purpose.

G Over the years a number of Amiga Desktop Publishing packages have come and Sample layout in gone. Some have been quite excellent and Page Stream. Some have been...well, let’s just say they were not quite what we hoped they would be.
Time, trial and error, and the input of Amiga users such as yourselves have molded the market into what it is today. Users and reviewers seem to agree that the Amiga DTP market currently has three major a packages. These three programs are [he most expensive, as - well as the most complex and they have an ever- increasing majority of the features offered by their non-Amiga big brothers. Professional Page
VI. 3 from Gold Disk, City Desk 2.01 from MicroSearch and
PageStream VI .8 by Soft Logtk. These are not the only DTP
programs out there, in fact, a number of tire word processing
v packages that are currently available have a variety of
low-level Desktop Publishing features. These tirree do
remain, however as the heavyweights if the Amiga Desktop
Publishing field these are the ones mm to beat.
PAGESTREAM V 1.8 As for PageStream, their latest version,
VI. 8, was being released about the time we compiled this issue,
PageStream was first released at the end of "88, making it t
h e “ n e w kid on t h e block” in Amiga DTP programs.
Unfortunately, Pagestream has been haunted by a reputation for crashing. While some people never seemed to have a problem with PageStream, others claimed they could barely keep it running. On the other hand, PageStream also has the reputation for being the most intuitive, ergonomically designed and user-friendly of the three giants.
Apparently this has been a strong enough recommendation to keep at lot of people buying and using PageStream despite actual and rumored problems. According to Gina Tilker at Soft Logik, version 1.8 will not only have several new features but should have all of those nasty bugs fixed! Here’s to no more crashes!

Perhaps with the continued proliferation of the ‘020- equipped 2500's Amiga Desktop Publishing will really flourish.
PROFESSIONAL PAGE V 1.3 Professional Page, originally released in January of ’87 was the first of these packages on the market. After four revisions, the last one being VI.3 (released last October), it is better than ever. Considered by some to be the premier CITY DESK 2.01 City Desk, in its latest revision (2.01), offers more speed and flexibility than ever before. Their latest manual is better written and easier to understand than ever before. In fact, MicroSearch is marketing a tutorial videotape made by Vanguard Video which will be of real assistance in learning the package particularly
for the firsttime user.
The folks at Sunrize Industries (who wrote the program), as well as the people over at MicroSearch (who publish CD 2.01) feel that they have gotten a bad rap from the Amiga market and particularly from the Amiga press. The reason, they feel, is that they are strictly a black & white (and gray-scale) program.
According to Tony Johnson at MicroSearch this was a tough design decision, but one they arrived at way back at the beginning.
Their view is that the majority of Amigans with color printers or access to color printers are going to be hobbyists or other nonprofessional DTP users with various types of dot matrix printers. They feet that the more serious Amiga DTP user may well have access to laser printers but will rarely have access to or really need the use of color. Who knows?
They may be right.
Among the many highlights of City Desk
2. 01 are the ability to auto-flow long documents (up to 99
pages) and the ability to download fonts to the HP LaserJet.
Desktop Publishing package, Pro Page has also had a reputation of being too hard to learn as well as difficult to use. Gold Disk claims the new version is now faster and easier-to-use, with more features than ever.
Professional Page 1.3 offers most of the features of higher-priced non-Amiga DTP packages.
Among the new features of their latest revision are the ability to import encapsulated PostScript graphics and ability to use Compugraphic fonts.
These are outline or structured fonts much like PostScript fonts, however Mary Lynn Hotte at Gold Disk says that the Compugraphic fonts have a much higher output to non-PostScript printers.
Serious Amiga DTP users have found a number of general workarounds to help the situation.
Extensive use of greeking has helped (for an explanation of greeking, see glossary).
Fortunately, the latest versions of all three claim to be (and actually appear to SUMMARY Overall, what has probably been considered the biggest problem of Amiga Desktop Publishing is speed, or rather, the lack of it.
Hopefully, now that Commodore has also announced the debut of the 2500 30 (equipped with a 25 mhz 68030 as well as a 25mhz 68882 and an MMU) things will really take off. Perhaps now the problem of speed is finally beginning to fade away.
What follows is a listing of some of the features of these three programs.The chart was compiled with information from the manuals as well as with the generous help of Soft Logik, features of these fine programs. We have also mentioned that an increasing number of Amiga word processing programs offer some basic page layout features.

are either brand-new to Desktop Publishing or are relative
newcomers, we offer this basic primer. Desktop Publishing
is different things to different people. Basically, most
people refer to DTP as any publishing which begins with a
personal computer. With as little hardware as an Amiga and
a printer, a person can print flyers, newsletters, menus
and more. For money!
Of course it helps if the printer is a top quality color ink-jet printer or a laser printer. It’s also helpful to have a top-notch word processor and a scanner and or digitizer. Having a large library offonts and clip art is nice too. A nd, most of all, it helps if you have a background in, or just an excellent sense of graphic design.
On the following pages we have undertaken to give you some of the basics of DTI3. We have included a glossary ofsome of the most basic and useful terms. We have also attempted to clear up some of the mystery surrounding printers, fonts, PostScript (and oullinefonts in general) and the various parts of a document. Also included is an explanation of what is meant by downloadable fonts and residentfonts. We sincerely hope you find ibis information helpful.

Thanks to the very industrious people in the Amiga marketplace, virtually every type of printer can now be used with an Amiga. These various printer types include:
• Daisy-wheei printers
• Dot-matrix printers
• Ink jet printers
• Laser printers
• PostScript printers DAISY WHEEL PRINTERS Daisy-wheel printers
are a type of impact printer. That is, letters are created on
the page by type heads actually hitting an ink or film ribbon
against the page. In the case of a daisy-wheel printer all of
tire type heads are on a circular wheel which spins into the
correct position just before printing each letter. These
printers are usually black & white, but in some cases drey can
use a colored ribbon.
DOT-MA TRIX PRINTERS Dot-matrix printers are printers which create letters and or graphics by putting patterns of dots on a page. In some cases these dots are created by impact with the page. These dot matrix printers are then also impact printers. These types of printer can either be black & white or color.
Resolution of these machines is measured by the number of dots which can be placed in an inch. The less expensive dot matrix printers typically reproduce 72 dots per inch.
INK JET PRINTERS Another type of dot-matrix printer, the ink jet printer also creates letters and or graphics by putting patterns of small dots on the page. Unlike an impact printer however, these dots are placed by heads which spray a small dot of ink on die page.
These printers can also be either black & white or color. The resolution of these printers usually runs about 180 dpi (dots per inch) but will vary widi make and model.
LASER PRINTERS Laser printers are non-impact printers which use the same basic principles of reproduction as a photocopy machine. A laser is used to etch the letters. Resolution of these printers is, in general, much better dian alt other types.
Generally speaking, resolutions of laser printers begin at a minimum 300 dpi.
The next step up in resolution is generally about 600 dpi. Laser printer resolution can go as high as a few thousand dots per inch.
Laser printers are now also available to do color printing but they typically cost tens of thousands of dollars.
They are still almost exclusively in die domain of specialty printing companies.
POSTSCRIPT PRINTERS PostScript printers are Laser printers which use the PostScript page description language and PostScript fonts. PostScript fonts may be sized up or down while maintaining the correct aspect ratio.
Resolution does not vary with the size of PostScript fonts or PostScript graphics (usually known as EPS, or Encapsulated PostScript).
$ u7 a tpr ntcr If you have not already bought your printer or if you are in tire market for a new one, there are several basic things to consider. For example, will you be using this professionally, semi-professionally, or just for your own entertainment? The answer to this question should help you answer many other questions such as: c* ¦JUST RELEASED- AMIGA™ UPGRADE 1 New 1 MEGABYTE, "FATTER Agnus ( 8372) Hi-Rcs chip allows users more “chip" memory for use in GRAPHICS.

1. What level of resolution do I need? Will 72 dpi be sufficient,
or will I need to go to 180 dpi or even 300 or 600 dpi?
2. How much printing will I be doing? This will tell you whether
to look for a light, medium, or heavy duty printer. Also this
should provide a good clue as to what kind of warranty to ask
for (or insist upon).
3. Do I really want, or more importandy, do I really need a color
printer?
It seems that most of us Amigans really want a color printer. It is really great printing outyour HAM graphics with an HP PaintJet, Xerox 4020, or similar machine.
Keep in mind, however, that the vast majority of lower level professional DTP work, i.e. the type you can realistically expect to produce in your spare room will probably be black & white.
You may be able to ««a prospective clients with 180 dpi color pictures, but to
(914) 354-4448 FAX (914) 354-6696 Dealer pricing available many
others nothing short of the 300 dpi resoludon of a laser
printer will look professional. It is also important to
remember that there are now a number of reasonably-priced
laser printers on die market, and their prices (or the
prices of better-quality used laser printers) may not be
much above that of a better quality inkjet type printer.
This may honesdy be die most important single question you
will have to answer. This answer will point you in one of
two directions in your effort to make the best overall
decision regarding your choice of printers.
4. Depending on your projected uses, the printer's speed may be
important.
Most printers will give two specifications.
One for letter quality or near-letter Quality (often listed as LQ or NLQ) and one for graphics. Once again, knowing what you will be doing is essential to the proper evaluation of these specs.
5. How much do I want to pay-’Flow much can I really afford? For
diese answers you must look deep into your heart (and your
wallet!)
There are several odier lesser questions you might want to ask yourself all of which really depend on your projected usage of the printer.
• You will want to know if the printer is single sheet or tractor
feed. Many printers can accommodate both. If it is a single
sheet printer it will probably feed from a tray. Can paper also
be supplied manually? How many sheets of paper will the tray
hold?
* Does this printer require a special kind of paper or is it a
"plain paper" printer?
How much does the paper for this printer cost5 It will not do any good to stretch your budget to buy a printer and then later find out that you cannot afford the paper.
• How about ink or toner? How much is supplied with the printer?
How long will it last? How much is it to replace?
Toner cartridges for laser printers can be very expensive, so can colored inks and ink cartridges. As regards paper and ink or toner, it is very important to get a very good idea of the operating costs of a printer before you buy.
• Besides the cost of inks toners and paper, it is very'
important (especially for those of you not living in a major
metropolitan area) to check on the availability of these items.
Is there a dealer nearby who sells these supplies? Are they
always in stock? Are they obtainable by mail-order? Will 1 have
to stockpile these items SO that I never run out?
• Will this printer also print on envelopes or mailing labels?
Again, it is vital that you really think out all of the
possible and probable uses of your printer before you buy.
• Also important is whether or not tlie printer has “resident”
fonts; how many it has and whether or not fonts can be added or
downloaded.
• It is equally important to make sure that a printer driver (a
set of computer- print er interface instructions) is available
for this printer preferably your DTP program will contain such
a driver.
Some of the more obvious questions which are easily overlooked:
• Is the printer a name brand?
While not a guarantee of perfection, few of the larger printer manufacturers became siiccesful by making and selling poor- quality units. If nothing else, having a brand name printer may make it easier to find service and or parts.
• While we're on the subject how about service and parts? Can my
dealer fix this printer if it breaks down? If not, exactly how
far away will 1 have to send it? In either case, how long is
the average turn-around time on repairs (including shipping, if
necessary).
• And speaking of service and warranties, what kind of warranty
comes with the printer, how long is it and exactly what is
covered?
These type of questions are very important to anyone who enjoys peace of mind, and they are vital if you have any thoughts at all of using your printer in a professional capacity.
In addition to thinking of major service problems, you should also investigate what sort of regular maintenance may be necessary'. For instance, with some ink-jet printers, you must regularly clean out die spraying heads so the ink does not clog. (By die way, some of the ink-jet printers have disposable heads; when you replace the ink supply you replace the heads. Check it out. There are advantages to both methods.
I have friends who swear by each different type.)
In general you must be aware of exacdy what you will be printing and make sure that all programs you may wish to print from are compatible with your printer.
Remember that even if DTP is your main thing, you may occasionally want to print from a paint program. Or perhaps you will want to print from an accounting program (to bill a client, for example). Or you may wish to print a list of clients from a spreadsheet program. As always, serious pre-planning can eliminate serious after- die-fact pain!

It has been available and in use for several years on both IbiM and iMacintosh computers. It is generally considered to be a standard in fonts and graphics systems. As of this writing, all of the
major Amiga Desktop Publishing packages allow at least some use of PostScript fonts.
If you are not yet familiar with PostScript, then “page description language” probably would not mean much to you. What this translates to in English is that in the PostScript system, letters and numbers (characters) as well as graphics (in the case of EPS [encapsulated PostScript) are described electronically by the parts which make up the characters or graphics and their relationships to each other with no reference to size. In offer words each letter is described in terms of itself.
This may still be somewhat confusing. Let’s try this.
Here is a computer describing a standard “E" to itself: There are a 1-inch vertical line and three 1 3-inch horizontal lines. The three horizontal Lines begin at the vertical line and go to the right. The first horizontal line begins at the baseline of the vertical line; the second begins 1 inch above the baseline, and the third line begins one-half inch above the baseline.
Here is a “PostScript” description: There is a vertical line of “x” height and there are three horizontal lines 1 3 “x” length. The horizontal lines begin at die vertical line and go to the right. One horizontal line is placed at 0% of “x”, die second at 50% of Y and the third at 100% of V. I'll admit this description takes some pretty serious liberties, but if die concept of outline fonts or PostScript was a complete mystery to you before now, perhaps this will give you a slightly better idea of what it is.
By the way, while PostScript may be the name most familiar to you there are other similar fonts. The generic name for these structured fonts is outline fonts.
Compugraphic fonts from AGFA Compugraphic is another well-known group of oudine fonts.
The bottom line is diat a oudine font or structured graphic is almost infinitely sizeable. And, unlike the bitmapped fonts and graphics which we Amigans are most used to dealing, they will never suffer from the “jaggies”. Even if you never quite understand the “mystery” of oudine fonts or graphics, it is pretty easy to understand this important point.

For more information, write to: Adriatic Coast Amiga User Club c o Carlo Mainardi Via Bologna n.13 47036 Riccione (FO) Italy JovMifoad 3*0 incase Taking the idea of postscript just a bit further... You may read in DTP books and
manuals about screen fonts, printer fonts, bitmapped fonts, resident fonts, etc.. Somehow it all seems very confusing. I’ll see if I can explain this without making you quite crazy.
Taking the easiest first: screen fonts are always bitmapped fonts. Basically this is an instniction to your computer to represent a character on you screen by using “x” amount of dots in a certain pattern. This is not always an instruction that a printer can understand. Remember, your Amiga's pixels are not square and not in any resolution. Also remember that the resolution of your screen is not the same as your printer. While most computers will attempt to reproduce a bitmapped font, the results are not always successful, and often they are quite disappointing.
Many printers will therefore have one or more resident fonts. What this means is that the printer itself ¦will have instructions regarding the printing of a font or fonts that have been optimized for that printer. These resident fonts are generally in ROM on die printer, or in some cases, they may be changed or added to with optional plug-in cartridges.
If your .Amiga does not have the same font as your printer’s resident font, there are basically two choices. You can make the printer struggle to attempt to print the Amiga font, or you can print using the printer’s font. In the first case your results may not be very good at all, while the printed results will be mucli better in the iater case, even though die end result wall not look like it did on your monitor. This can make page layout very difficult as you will have to print each section of your document out before you really have any idea what it will look like.
In the case of a PostScript printer, things get a little more extreme. While a PS printer will always want to print in a PS font, a PS font cannot be properly represented on your monitor. Therefore, when working in a PostScript environment.
You really need two versions of each font you will be working with, your screen or bitmapped version and die printer’s PostScript version.
What if your printer does not have a particular PostScript font? Where does that leave you? If your printer is the type with interchangeable font cartridges, then you can just go out and buy the proper cartridge. If this is the case, there are some programs that still give you an option. In some cases you can “download” a font to your printer. Most of the better printers wili accept diis but you must have this capability both in your printer and within your DTP program. In die case of a PS printer, your program will then use its bitmapped version of a font for representation on your monitor,
and it will then download the PS version of the font to your printer’s memory before printing.
Generally speaking, this will have to be done each time you reboot, because your printer will hold this information only temporarily.
It may also be important to note that diis also works with many non-PS printers.
Some programs, for instance, will download fonts to the Hewlett-Packard Laser Jet printers.

P. O. BOX 17882 Milwaukee, Wl 53217 This article is an
introductory tutorial on disk sector editing. It is a “hands
on” article heavy emphasis is placed on actually doing
something useful with the editor, while being light on theory.
For those who wish to delve deeper, references are included.
The project is to re-size die default values of die Shell CLI
windows by malting three sector edits in a couple of files. It
is intended for people with no sector editor experience. For
indivduals widiout a modem a couple of easy ways to get the
software have been included.
Resizing the SHELL AMIGA WINDOWS CLI WI with a Disk NDOW Sector Editor by William A. Jones Exacdy what is a sector editor? It is a program that allows access and modification of individual bytes of data on a disk. The disk is read from and written to directly. This is a very powerful capability, and a great way to learn about disk structure, THE PROBLEM What inspired this project was a dislike of resizing the CLI window eveiy time it was called. Along came AmigaDOS
1. 3 with the answer on page two of the Enhancer manual. Or was
it?
The instructions on page 1-2 of the AmigaDOS 1.3 Enhancer Software manual for changing the size of the Shell window do not work. At least not on my 500, with my current understanding of the English language. I'm a Southerner(y’all), so language might be the problem, but I suspect either a misprint somewhere, or my lack of the 1.3 ROM chip is the culprit.
When I include WINDOW=NEWCON:0 10 480 190 Myshell in die Shell INFO window from the Workbench, nothing changes.
Using ED to include die same line in die s:shell-startup file yields the message “Unknown Command WINDOW" and no change. All possible combinations of upper lowercase and spacing were tried, but to no avail. Giving die monitor a good stiff whack did not work neither. There is probably a simple answer to all this misery, but then 1 wouldn’t have learned die following sniff about disk sector editors.
Which is what is needed to customize a Shell window. There are several good sector editors available in die public domain or as shareware. Two of the best known are Newzap and DiskX. Bodi are recommended, as they have different strengths.
Newzap 3.18 is a file-based editor. It is shareware and die price is right. The documentation is one page long and reading it is unnecessary for this project.
However, it should be read. It is extremely intuitive; about ten minutes are required to learn how to run it. Since it is file-based the search time for a file is nil this puppy is fast. And it runs under AmigaDOS 1.3, even though the version used only mentions 1.2. It limits use to the sectors connected to the file being worked on.
Random roaming on the disk is not possible. For a beginner this is not a negative. Unlike most sector editors, Newzap displays the entire sector on screen at once, A small thing, but it contributes to that ‘feel’ of a good program.
DiskX 2.2 is a sector-based editor. It’s by Steve Tibbett, of VirusX fame, and general good Samaritan to the Amiga community, and it is free! It requires ARP to run. The documentation is 3 1 2 pages; it needs to be read carefully. It is not intuitive. For example, hitting the return key is required BEFORE making an edit.
It is more powerful than Newzap, in it ability to access any sector on the disk.
This is a very useful feature to have. Boot blocks are available on DiskX. Search time is much slower. When a file is called, the search begins at the beginning of the disk and takes a while to find the file being accessed. The drive runs continuously while DiskX is in operation, which can be kind of disconcerting. Steve says not to worry.
To be fair, I didn't spend much time using DiskX. I just happened to try Newzap first, and it did the job with no hassles. It took some time to get DiskX online. Mix an old version of ARP and a 1.2 ARP loader with an overcrowded 1.3 Workbench. Stir in a lot of file copying and deleting, and the result is a frustrating afternoon. All, the joys of living 100 miles from the nearest users group. By die time this is read, ARP 1.3 will most certainly be available.
! Wanted a “quick and dirty” tool for the job at hand. Newrzap is quick but not dirt}'. It let me concentrate on the project, not the tool. For this project I recommend Newzap, especially for a novice at sector editing.
DISK STRUCTURE Let's take a QUICK look at disk organization. In descending order of magnitude die disk is divided into two sides, 80 tracks (laid out as concentric rings) per side, 11 sectors per track and 512 bytes per sector. A byte roughly corresponds to a character. For example, the word ‘cat’ would take three bytes on the disk.
A disk sector editor reads and writes directly to individual bytes of data in a sector on disk. To be stricdy accurate, die Amiga reads and writes a track at a time, but diat won't affect this project. The data is either in ASCII text (stuff that can be read with a text editor), or binary (stuff that appears as garbage in text editors that try to read it some, like ED don't even try.)
What is going to be done is, a few bytes in two files which contain both binary and ASCII text are going to be changed. Which is why die sector editor is needed, rather than a text editor. Thus ends the theory. (I did say QUICK.)
For an in depth look at disk structure, Amiga Programmer’s Handbook Vol. II by Eugene Mortimer has a chapter on the trackdisk device. This is the low-level software interface to the disk drive, and the chapter provides much more information than needed for this project. It includes an informative picture of disk structure. The first chapter in the Technical Reference Manual portion of die AmigaDOS Manual has a chapter on die filing system widi great detail about disk structure.
USE CAUTION This is a good place for die standard disk editor warning. Do all work on a COPY of die Workbench disk. Actually, make that a copy of a copy of the Workbench disk diat is normally used, if die standard Workbench has been modified. This is industrial strength hacking that’s being done; it's easy to corrupt a disk. And I am definitely NOT referring to a hard drive here. I don’t have a hard drive. I know next to nothing about them. Do NOT use diis article as a guide.
STOP! CEASE! DESIST! It’s one diing to recopy a 3.5" floppy. Recovering from a hard disk crash is another. Well, if it must be tried, go ahead. It might work! Good luck, and don’t blame me.
THE SOLUTION
O. K. Let’s get our hands dirty. Here is a step-by-step walk
dirough for changing the size of the Shell. These instructions
are Specifically for die Newzap editor, and apply to both one
or two drive systems. If a different editor is being used, the
information needed is included further down in the article.
1. Boot a copy of Workbench and double click die Workbench disk
icon.
2. Load and run Newzap.
3. Click the Filespec box.
4. Enter ‘dfO:system di’ (no quotes) and hit return.
5. Select String Search from the search menu on the menu bar.
6. Enter ‘newcon (no quotes) and hit Picture yourself at the
next user group meeting standing around looking nonchalant as
you toss out the line, "I was customizing my Workbench with a
sector editor the other day and..." Instant wizard status.
Return.
7. On die right side of the screen you’ll see NEWCON:
highlighted. Click on die ‘5’ (3rd character after NEWCON: and
type ’10 480 190 MyshelT (no quotes) and two spaces to
overwrite the two l's from the old ‘Amigashell’). Do NOT type
past the end of the old ‘Amigashell’.
8. Click the save gadget.
9. Click the back gadget to get to the Workbench and double click
the Shell icon. 10.
Yell TA DAA!!! Type 'endshell' (no quotes) and hit return If die Shell is going to be called from the Workbench that's all diere is to it.
However, if the CLI needs to be the same size, dick die Workbench back gadget, find the word CON: (it’s the next word past the edit just made) and change die dimensions and name like step 7. Repeat steps 8-10.
Now double dick the shell icon.
When Myshell appears type 'newshelf (no quotes). As we say down South, "Ids jes one dam diing afta anutha.” Since you are now a veteran sector editor guru, fixing this one is easy. Just do the same steps on a different file. Back to die sector editor: In step 3 enter ‘dfO:c newshell’ (no quotes.)
Then repeat the rest of die steps, and type ‘newshell.’ If a different disk sector editor is being used, here is the needed information.
The file ‘dfO:system di’ is six sectors long.
The text being changed is in sector five.
Similarly, die file 'dfO:c newsheli' is six sectors long, and the text is in sector three.
The Enhancer 1.3 manual is correct here. The first two numbers determine where die window will appear on the screen. The 1st number (the one we didn't change) is the * of pixels from die left edge of the screen. The 2nd number is die of pixels from the top. The 3rd number is die width of the window, and the 4di number is the height of the window. Experiment widi diese to put die Shell window where it is wanted. The numbers I used put a window about 2 3 of the screen wide, (die disk icons can still be seen) and the height of the screen minus the top menu bar.
The maximum height appears to be 200 (10 + 190.) If this height is exceeded, it will not work. The same problem may exist, if 640 is exceeded for the width.
CLICKDOS The hardest part of customizing die Amiga interface is finding die files to edit.
Some suggestions: look through die C, libs, prefs and system directory files for strings of ASCII text. The sector editor or a directory utility, like Clickdos, can be used.
Clickdos lets you roam through directories and subdirectories on a disk with a few quick mouse clicks.
For example, die way I found the CLI file in die system director)' referred to back in step four is as follows: Click the ‘iconify’ gadget. This causes the small window on die Workbench menu bar to expand to full screen size. The screen displays two directory areas. Click the DFO: gadget beneadi either area. This displays the contents of the disk, directories first. Click on the system directory, then click the ‘child’ gadget. This displays what’s in the system directory. Click the CLI file. Click the TYPE gadget. Click the screen requester, (gee, I wonder why it’s called Clickdos) and you are
looking at,. .gibberish. Clickdos reads binary as well as ASCII. Click anywhere on the screen.
Eureka! There are the lines to alter. This takes less time to do than to describe. A couple of hours with Clickdos and you can go through every file on the Workbench.
Clickdos also has the ability7 to copy, move, makedir, delete, rename and call a
CLI. Copying is particularly easy. It also views IFF ILBM
pictures. Be sure to read the (continued on page 66) AMIGA

This may be the program for you.
How many of you have that “perfect desk” at home or work? You know, the one where anyone (secretary, spouse, or friends) can easily find important information, like phone numbers or your list of important appointmentsfor the day.
If so, you are fortunate! I keep trying, but I have had little success in keeping my desk organized in a manner understood by anyone but myself.
Blue Ribbon Bakery has a product called “Who!What!When!Where!” (from now on referred to as WWWW), that insures the gratitude of any other person needing to find your important personal information when you are not around to help them look for it.
WWWW acLs as a personal secretary, keeping track of important names and numbers for scheduled appointments and an itinerary of important things to do. This program displays information in separate windows for die Calendar, Directory, and Things To Do in a manner similar to WP Library. A timer, which is run from the startup-sequence to notify users of upcoming appointments, monitors the system dock.
Since WWW muldtasks, it sits quiedy as an icon.
PERSONAL DIRECTORIES Up to 14 different people can share WWW on a single Amiga, with each individual having a private password to protect his directory's informadon from spying eyes. Sharing informadon between different users is easy, with each user selecdng how much they wish to share!
Each directory has two smaller windows within it: one is a form displaying name, address, city state zip, phone number, birthday, groups, and notes forpeople you fill in the blanks. The second contains die list of file names (like the index for a card fde), which contain the information needed to fill in the blanks for the form.
The data files for individuals are stored where you choose, on any floppy disk or hard-disk drive directory.
Each person business in a directory list can have individual appointments. View a List of appointments for the person business currently displayed in the window, or appointments with others not cunrendy displayed. If a person does not have any individual appointments, none are displayed when selecting APPOINTMENTS WITH.... However, selecting APPOINTMENTS WITH UNLISTED will display a list of all appointments accessible widiin this directory.
THE CALENDAR The Calendar displays either Appointments or a Things To Do list for each day of any month. To select which list you want displayed (either Appointments or Things To Do, but not bodr at the same time), click on the appropriate gadget at the top left comer of the calendar. To change months, hold down die right mouse button and select the month you wish to be displayed. To view the list for a specific day, simply click on diat day and your Things To Do or Appointments list will appear. Appointments are viewed for eidier one or all of die users. The displayed list is sorted
in either alphabeucal or chronological order of appointments. If an appointment repeats on a regular basis (daily, weekly, bi-weekly, monthly, or yearly), it only needs to be entered once. A list of Appointments can easily be sent to the printer.
THINGS TO DO The Things To Do window displays What, When (time and date), New, and Delete gadgets. The list of Things To Do is automatically rolled over to the next day if you do not check it off your list. This is a very useful feature for all those procrastinators out there! A list of Things To Do can also be sent to the printer, if you have the need for a hard copy list. I keep track of .Amiga magazines and software publishers with WWWW and use the Things To Do as a reminder to mail out an article or write call a company about a product. Click on the checkmark for an item when
it’s completed, and it will no longer roll over to die next day’s list of Things To Do. I check die Things To Do whenever I want to see what I need to catch up on.
WWWW ships on a single unprotected disk, although manual protection is used. Installation for the program is simple; just use the Install requester to set up the location for all data files. One thing I would emphasize is to make sure die run wwwwtimer in the s:staraip-sequence comes after SETCLOCK, or you will have problems with the copy-protection scheme, which is date-sensitive. The WWWW Alarm can eidier use a bell, a voice, a sound effect, a screen flash, a message sent to an Arexx port, or any combination of these. Yes, WWWW is Arexx- compatible!
The manual gives adequate coverage of the use of the program and all its features, but I would have preferred a spiral- bound manual. A bound manual makes it hard for frequent manual readers to keep open to a specific page while working with die program. Tliis objection with die manual is my only major complaint widi this product, although 1 also wish the WWWW program itself was smaller than 133K it takes up a little too much space on a single disk drive system! The price is quite reasonable for this type of product on die Amiga. I use WWWW nearly every day and can heartily recommend
it to most people, especially businesspeople and students who need to keep track of important engagements widiout the hassles of eidier easily misplaced notes or appointment books.

Blue Ribbon Bakery 1248 Clairmont Rd., Suite 3D Atlanta, GA 30030 1-404-377-1514 Price: $ 79.95 Inquiry 200 VTX On-Line review by VTX On Line Mllhlion Modems are in high demand on the Amiga, and so are the high-quality terminal software programs used to operate them. VTX On-Line has some very advanced features for a terminal program, which allow the user to communicate easily with a variety of systems. Unfortunately, it falls short in some of the more common features found in most terminal programs.
VTX On-Line is just one of die many players in a well rounded market of commercial, shareware, and public domain programs. It has no features that place it far ahead of any other program on die market, but it definitely has some features that make it woith looking at, particularly for a variety of different specialized applications.
VTX On-Line’s main problems are that it is best suited only for diose specialized applications (as opposed to general telecommu- nicadons work), and it is very' buggy.
One of VTX On-Line’s strong suits is its ability to communicate with mini computers such as Digital E qui p m eri t Corp s VAX and a host of various UNIX machines. VTX On-Line accomplishes this dirough its variety of file transfer protocols and emulations.
Vr-ioo?
Most terminal programs lout true VT-1 GO emulations, but most of them, including VTX On-Line, miss out on a few key features. VTX On-Line, however, has an almost complete VT-100 emulation. It supports the standard codes to relocate die cursor along with a host of other features that are not usually emulated, such as double width and or height characters. VTX On-Line even emulates a code that DEC engineers use to do diagnosdc work on real VT-100 terminals. Unfortunately in my tests, I was unable to get the graphic characters that are used on a VT-100 to -work correctly.
Even though die oilier features in the VT-100 emulation work great, this setback makes it hard to use in place of a real VT-100 terminal.
VTX On-Line lias other emulations besides VT-
100. It supports ANSI emulation for use with a bulletin board
system (BBS), Tekrronix-4014 emulation for certain
mainframe, mini and supercomputer applications, and
Prestei emulation which is documented to be useful to
European users. I was unable to test Prestei and Tektronix
emulation because diey are not in as widespread use as
VT-100 and ANSI. VTX On-Line did a fine job of displaying
the colors in the ANSI emulation, but did not fair well at
all when it came to displaying the graphics characters or
positioning the cursor in accordance with the ANSI standard
used 011 many IBM and Amiga BBS’s.
FILE Trri.XSFF.R As far as file transfer protocols go, VTX On-Line touts ASCII, Xmodem, Xmodem CRC, Xmodem-IK, Ymodem, Kermit, and CompuServe's B Protocol. The protocols all wrork excellentiy and get fairly efficient diroughput speeds. The Kermit protocol offered is very useful in conjuction with some of the emulations, : particularly when you are communicating witii UNIX based machines, the Digital Equipment Corp's VAX, and many mainframes. Al! Of this is well documented ¦ in the manual, which is extremely well written and one of the best manuals I have seen for this type of program A feature
of VTX On-Line that I did not particularly care for was the requesters used in the program The author’s intention to make all the requesters : controllable by either mouse or keyboard was a very ' good idea, but in reality it leads to confusing operation and a loss of functionability in die requester. Por instance, the file requesters do not allow you to double click on a file name to select it and then exit the requestor. There is also no way to activate die OK and CANCEL buttons from the keyboard. While this may not seem like much, it makes having keyboard activation a waste since you need
to go to the mouse anyway to exit the requester. The requester also crashes the system when an invalid directory name is selected. I also found a few other bugs in the requester, when using the keyboard that, I am told will be fixed in the next version.
THE PHONE BOOK VTX On-Line also has a phone book where you can enter the names and numbers of popularly called services. You are also able to assign a different configuration and script that is automatically loaded each time you dial that number, which is an extremely useful and time saving feature, since you do not have to reconfigure all the terminal preferences everytime a certain number is dialed. Since each entry- in your phone book may have a different setting, you can easily see what a pain life would be without this feature. One of the flaws with die phone book is that you cannot
click on multiple enuies and have them dial consecutively until a connection is made. In fact, you can’t even double click on a phone number to dial it. There is also a problem with the cursor advancing to the next line when you are entering a new phone number. The program doesn’t even hang up the phone if you click cancel. This can be very aggravating if you start dialing a long distance number and just as it begins dialing you remember it’s die wrong number, Theoretically, you should be able to click cancel and it will hang up during the dialing, saving you connect charges, but in reality
VTX On-Line does not hang up die phone, possibly cosM| you money. A :h. L Ullltl THE B-LD NEWS I have some other minoi qualms with the package. For example, it reassigns the fonts iqifce VTX On- Line disk and never assigns them.back to where they were originally; This can be very annoying to hard disk users. It also has a strange , bug m the cursor (when using inverse video) where die cursor leaves trails on lines where return was typed The program also lacks a review buffer such as that found in many popular terminal programs. This allows you to go back and review things that have gone off
the screen in case you missed somediing. The most peculiar bug I found is that there is a drawer full of demos for VTX On-Line that would not run no matter what I tried. The demos drawer was not mentioned in the manual and may have been just left out of the program, THE GOOD NEWS VTX On-Line has the ability to receive and display pictures in the RLE or GIF formats. RLE graphics are used on CompuServe to display and transmit pictures while online. GIF graphics on the otherhand have a far greater use. GIF graphics are able to be displayed on die Amiga, the IBM, the MAC, and it is even rumored to
be available on the Commodore 64.
This is useful if you have more than one computer, or if you want to draw something on an IBM at work and download it to your Amiga at home so that you can touch it up with an Amiga paint program. VTX On-Line goes so far as to even display 256 color pictures created on a MAC II in HAM mode on the Amiga.
Another nice feature of VIX On-Line is its ability to communicate with and be controlled by Arexx. In case you have been asleep for the last year or have just purchased an Amiga, Arexx is a powerful macro processing language that allows many programs, with the proper interface written into them, to cptiiniunicate. With:each other, and they are able to lie controlled and reconfigured by the user. This allows the hserto'custoinize die program to their liking, and also:to write scripts that interna with multiple programs. Having: this ability in a terminal.
Program greatly expands: the possibilities that ciil be : achieved using Arexx.
Probably the best feature of VTX On-Line ls. The ability to write automated scripts. It is possible; to .write a: script that dials your favorite BBS oi; service, logs in, reads : your mail, gets a list of the newest files;, and then logs oft.
This allows you to save time and iriOuey, if you have the script automatically start at night when the longdistance or network connect charges: ar i jcwer; Tiie-.scriptlanguage allows you to perform any available function automatically. There is also a “learn mode" where you can log onto a service, such as a BBS, and VTX On-Line will make up a script for that BBS as you go along and then save it to disk. Unfortunately, diis feature has its bugs also.
The first one is minor but annoying: die gadget to cancel the script does not respond to one click. It needs two clicks before it will acdvate. The second is not so minor.
Hitting return after cancelling a script will cause die program to crash, resulting in a GURU.
THE FINAL WORD While VTX On-Line has many features, it also suffers from many bugs. It is a very good package for what it does, but it is easily out performed by some of the better public domain packages available for free on commercial networks and bulletin boards. The program should be very useful, not to mention powerful, once all the bugs and peculiarities are straightened out. I contacted Micht- ron about die bugs and about some of die features that I thought were missing. They said that diey were trying to fix die bugs quickly, but they didn’t know whedier or not they woidd add in any of
die features (that I thought should have been in there in the first place), such as a hang up key.

The Bandito [The statements and projections presented in
"Boomers"are rumors in the purest sense, the bits of
information are gathered by a third- party sourcefrom
whispers inside the industry. At press time, they ream in
unconfirmed and are printed for entertainment value only.
Accordingly, the staff and associates of Amazing Computing™
cannot be held reponsiblefor the reports made in this
column.] While the Bandito is rarely startled by the data
that flows by on the bit stream, occasionally an item pops
tip that jars even the Bandito's complacency. Some
determined hackers have cracked the AMAX code and posted
the entire thing (Apple ROMS and all) on some BBS's. So
this means there is no need to have the AMAX hardware with
this software; you just tun it, and the Amiga is then ready
to run Macintosh software (ali tire ROM calls are diverted
to the “ROMs" being simulated in memory), The Bandito
strongly advises everyone to stay away from it. If this
gets out, two bad tilings will happen. First, ReadySoft
will have no incentive to make further improvements in AMAX
(like hard disk support). Second, Apple Computer would have
grounds for a lawsuit, possibly even an injunction against
Commodore to make them stop selling Amigas! This is
serious. Right now, Apple has the FBI investigating the
pirates who were distributing some of Apple's source code
to the ROMs. It is important that loyal Amigans know about
this and squash it hard before it ever gets out.
Legal Battles The lawyers have been extra busy lately, so the Bandito brings you an update.
Atari Games has lost the fight over Tetris; Nintendo gets the rights to the cartridge version. No resolution yet in die big battle over Nintendo cartridges, but die latest development bodes ill for die Nintendites.
Now a Congressional subcommittee has asked the Justice Department to investigate Nintendo for monopolistic practices, ¦which could mean some legal action from the government against Nintendo and perhaps a glorious victory for Atari Games.
One of the tilings that got the Congress so fired up is that Nintendo machines sold in the U.S. contain a chip that's sole purpose is copy protection, preventing nonauthorized cartridges from working (Tengen, an Atari Games’ subsidiary, was able to create a canridge that ignored this chip!). What ready teed off the committee ¦was diat Nintendo machines sold in Japan do not have this chip.
Personally, the Bandito soil hopes die Nintendo craze dries up and blows away so that developers can spend their time working on more Amiga games. But everybody salivates at the thought of selling 500.000 cartridges per title instead of 50,000 disks for a successful game.
And in the very latest in legal maneuvering, Xerox is nowr suing Apple for $ 150 million over the copyright to the Macintosh look and feel. Seems Xerox wants to get Apple's copyright declared null and void. Why did diey wait so long?
This lawsuit makes Apple’s case against HP and Microsoft look pretty funny. In one courtroom, Apple argues that they own the copyright to the look-and-feel, and in the odier, they claim that look and feel can not be copyrighted. What is the Amiga angle on this mess? Well, Xerox is already getting royalties from Sun and Metaphor, and Apple balked at paying up (even though the fees are rumored to be quite reasonable, as these things go).
Speculation is that Commodore has been approached, but no word yet on whether or not they will pay the royalty that Xerox demands. The Bandito is already putting out sensors to find out the real stone Stay tuned.
Other Game News Commodore is poised to make its entry with a splash. The game machine based on .Amiga chip set is almost ready, and reports are that it will be a killer. It is basically an A500 without the keyboard and most of the ports, adding a cartridge port and (the big news) a CD-ROM player option. Key developers are already working on products, which in many cases are easy (especially for many of the European games). Commodore has decided that there is money to be made there, so development has kicked into high gear. The CD-ROM player option is the most exciting part. Unless Commodore is
totally brain dead, they will also offer die CD-ROM player as an Amiga option (since die game machine uses the Amiga chip set).
Think of the kind of games you could have
- diere is room for 10,000 lo-res images plus an hour's worth of
digitized music.
The plan makes sense to the Bandito, even though there's already two advanced game competitors out there (the TurboGrafX and die Genesis) with Nintendo’s 16-bit machine on its way. The Amiga's sound and graphics capabilities are still far better than any of these machines, and die Amiga also has what these machines lack: a huge base of software. Developers are already working on polling their game software to the cartridge format, which is not too hard in most cases. The Bandito hears that Commodore has settled on 512K RAM as the standard, and there may be an option to increase this to 1
megabyte. The price point on die machine is said to be around $ 200, with die CD-ROM player an additional $ 300.
You can also expect a lot of Amiga games to become Sega Genesis cartridges and vice versa. Why? Because both machines are based on the 68000, and porting the code is very easy. The TurboGrafX is a fast 6502, which is much less compatible.
Will we see a cartridge port on a future version of tire A500? If the video game is a success, it could be in the Amiga’s future. Or possibly a low cost adapter that plugs into one of the existing ports would do the trick. Hey, that sounds like a product opportunity for some enterprising developer.
Expo Europe The Bandito’s spies are everywhere, even in Europe. They report that over 50,000 people attended the Amiga '89 show (AmiExpo) in Cologne, Germany. Friday alone was busier than tire busiest day of any AmiExpo in the U.S. By Saturday noon the show was packed solid, and 10,000 people were waiting to get in. A riot nearly started when people were turned away.
Several developers were overheard to mutter “why can't the shows in the states be like this?"
The other eye-opener for the Americans at the Cologne show was the amount of piracy going on (not at the show, but there was plenty of evidence to be found). Software sales in Europe are not anywhere near what they should be, given tire amount of hardware that Commodore is moving. Add-on Amiga hardware sales are doing fine, but software is not.
According to developers, piracy is rampant in Europe. It is even supposedly condoned by some Commodore officials in West Germany, who privately express tire opinion that if it were not for all tire “free” software, people would not buy as many Amigas. This attitude makes software publishers turn at least 32 different colors.
In other show news, Commodore’s big announcement at Comdex (where they looked lost among tire sea of IBM clones) was tire long-awaited A2630 card, offering a 25 Mhz68030, a 68882 math coprocessor, and 32-bit wide RAM. They have built it into a 2500 chassis and are calling it the A2500
30. This is NOT the Amiga 3000, sports fans.
But it is a screamingly fast machine two to three times faster than a 2500, Almost makes rendering Sculpt images quick...almost. Of course, you can always buy tire card and slip it into your own A2000 for some supercharged performance. The A2630 supports up to 64 megabytes of RAM. Just THINK of all the different programs you could have running at once!
Amiga Homefront Some dealers are not happy with dre Commodore ad campaign because dre sales boost they got is lower than drey expected. But computer sales of all brands were sluggish this Yuletide. Buck up. Folks.
The Amiga’s doing better than most.
Crabapptes Apple has had a tough time lately.
First of all, despite an expensive marketing push, Apple is finding it very hard to sell products to dre video market. Macs are too slow widi animation and have bad video output, even after you spend thousands on adapter cards and boxes. And the software selection for video tiding and animation is padretic.
Apple stock has taken a beating lately, since they have been hit with dre Xerox lawsuit, and they revealed their Xmas sales were well below expectations.
Their stock has dropped 15% in about a week. It seems that their unit share has dropped down from 15% to a mere 5%, and sales of dre Apple II line (which accounted for most of tlreir units, though not most of dreir profits) have also slowed. The Bandito has discovered that total Apple II line sales for 1989 are less than 100,000 units worldwide - that’s including He’s, lie's, and Ilgs’s.
So Apple is trying to revive tlreir share of die home and education markets with the Cheap Mac. Basically, it will look just like a Mac SE, with a retail price of less than S1500 (perhaps $ 995). So what is the big deal? By that time, you will be able to get a comparable A500 system for well under drat price, and you have got color, stereo sound, multitasking, and more. The Bandito predicts drat the LCM will be a flop unless drey can come up widi another gimmick. Ooh, they are also talking about a color Macintosh SE for a list price of $ 2000 (without the monitor). Amazing, a color computer for
about S2500 (that is with a color monitor and one disk drive) - what will they think of next?
Where is the BeeJ?
Apple’s not the only computer company having a problem lately. Atari is having trouble bringing the Lynx handheld video game to the market. Citizen has raised the price of the LCD screens, so Atari will eidrer have to raise the retail price of the Lynx or take a lower profit margin. And apparentiy the entire development system was not transferred to Atari before they lowered die boom on Epyx, though they arc trying hard to get it finished at Atari.
Despite a good turnout at the developer's conference Atari held in California, rumor has it drat nobody is working on Lynx development outside of Atari. What is left of Epyx would dearly love to get the royalties from the Lynx, but the people who knew tire most about dre development system are no longer at Epyx to help Atari understand it. And Atari would love to put the development system on an ST instead of an Amiga, but that may be damn near impossible. What a mess. Meanwhile, Nintendo’s Lame Boy is zipping off the shelves, propelled into high gear by a megabucks advertising campaign.
And then there is Big Blue. The Bandito hears that IBM’s HPC is reaching some developers under very tight security.
IBM regs call for locked drawers, all equipment locked up in very secure locations, documents marked Top Secret (Bum Before Reading), and so on. They enforce this with surprise inspections and a sneaky trick: every developer gets a separate code name for the hardware, so if leaks occur IBM knows where to look. IBM is working hard to get some applications ready for shipment of the system education and recreation are both important target areas. The Bandito has sifted die evidence and believes diat IBM is looking for a Christmas 1990 ship date; however, they may be forced into a first quarter
1991 ship due to hardware and software availability problems. The latest price quote: $ 3,000 for the machine.
Microsoft’s interest in multimedia may prompt diem to reopen discussions with Commodore about software products.
The Amiga could be a test-bed for some of their new ideas, especially since it looks like Microsoft’s vision of a multimedia MS- DOS machine (the HPC) will be too expensive for a couple of years to create die kind of large market they need. So they are looking at the Amiga’s installed base of over 1 million (probably 2 million by the end of 1990) with a speculative eye. The Bandito says why not? Just do not give us an operating system. We already have all die neat stuff you are trying to put into OS 2, and Intuition takes a little less dian 4 megabytes to run in. We would not mind anodier
word processor or spreadsheet, though. Work on it and get back to us when you have something.
* AO* by Barry Solomon
• How High is Hi-Fi? • The facts about audio for video!
Well, hello again. I was thinking the other day ahout what to write for this month’s column. I was stuck for a little while, so I began reading a new book that had just come into the AC office for review.
The book is entitled Amiga Desktop Video by Steve Anzovin. There I was reading along when I spotted a reference to something that has become one of my pet peeves.
The reference was to the Hi-Fi sound feature on a VCR. The reference was neither incorrect nor, I am sure, was it intentionally misleading. But it made me crazy nonetheless. The fact is that most people (including most audio video salespeople and even some desktop video pros) do not really understand Hi-Fi VCR sound.
Represents video signal helically recorded on closest surface of tape.
Represents Hi-Fi audio signal recorded onto deeper layer of tape. ..... JUST THE FACTS First of all, let me clear up the first misunderstanding. 1 am talking about what is known on some Beta and some VHS VCR's as Hi-Fi sound or Hi-Fi Stereo sound. This relates to your home stereo system only indirectly; through tire original usage (circa the early 1950’s) of tire term Hi-Fi which was short for High Fidelity.
Hi-Fi referred to tire (then) new generation of recording and playback equipment which was finally able to reproduce music throughout the entire range of human hearing (20 to 20,000 cycles per second; now' referred to as Hertz). For you youngsters out there, remember, this is still almost ten years before stereo became widely available!
When consumer VCR’s first became available, only monaural (mono) sound could be played back and recorded. The quality of the mono soundtrack was (and still is) pretty poor. Remember, when recording anything on tape, be it audio or video, the faster the tape passes the record or playback heads, the better tire sound is.
It should not take a degree in engineering to understand this.
If a tape is moving by the record heads at one inch per second, and you record a one-second note, then you have a one-inch long “description” of the music on tape. If you record that same one second of music with die tape running at two inches per second (ips), then your “description” is now two inches long. Get it? The longer the “description” the more accurate it can be.
Try describing your house in three sentences. Now try it using six sentences.
Odds are, I will pick up a lot more information about your house from the second description.
If you know-- only the most basic technical facts about a VCR, you know' that the video is recorded and played back by using record and playback heads which are mounted on a rotating drum. This is done to increase the tape-to-head speed. In the case of video, this wras not done to increase the fidelity. It was done to make recording possible! Video signals are so complex and cover such a wide bandwidth that they cannot be recorded at the speeds of standard consumer audio equipment.
They could have just worked out a way to have the tape move very fast across a stationary head, but you wmuld have had to change video cassettes every five minuU.s or so, (You would have needed a shopping basket to get Gone With The Wind from the neighborhood video store to your car.) So the tape moves slowly, and the drum with the heads spins madly away to get the required speed. Where does the audio portion come in? Well, the mono audio track was and is recorded along a narrow' strip on the edge of the tape by a stationary head. Remember, the video tape is actually crawling past this
stationary audio head. The speed is actually somewhat slower than the speed of an audio cassette deck, The sound, therefore, is not too good.
DOLBY STEREO In the early 1980’s some VCR manufacturers began producing machines with “Dolby stereo". This w'as a system by which the mono soundtrack w'as divided into two sound tracks, left and right, for stereo. Now we had this extremely slow- moving, extremely thin strip of sound-on- tape divided in two! As with faster speeds, fidelity is usually better, if there is more area on which to record. So now we finally have the possibilitv of a stereo soundtrack, but the draw'back is excessive noise.
This is where the Dolby part comes in. These machines incorporated a system of noise reduction licensed from Dolby Labs, inc. very similar to the “Dolby” on your average audio cassette. So now we have a VCR wriich can record and playback stereo sound. This was a major advance- ment for tire home video industry. First of all, since we all have two ears, located (preferably) on either side of the head, we tend to hear our normal environment in stereo (Actually, what we perceive is binaural sound, but it is pretty much tire same idea.) This means that stereo sound of any quality tends to sound
much better and much more natural to us than mono sound of comparable quality.
Secondly, in case you have not noticed, movie makers have been spending more time, effort and money creating the soundtracks for their movies.
In fact, for the movie Indiana Jones and the Temple of Doom, which w'as filmed almost five years ago, die producers spent over $ 5 million on die soundtrack alone!!
So here, at last, wre have a way to convey some of the impact of a movie's music and sound effects in our own homes.
The difference, compared to mono sound is astonishing. In fact, I was one of the many people who immediately ran out and bought a Dolby stereo VCR. Of course, when this feature was new, only the top-of- the-line models had it. So that was what 1 was forced to buy in order to get better sound.
The problem was that, as nice as this improvement was, the fidelity was still our surroundings (the ceiling, walls, floors, the person sitting next to us, etc.). In almost any environment there will be some continued bouncing as the sound bounces back and forth, between several surfaces, before reaching our ears. This is called reverberation. Our ear brain combination environment. In fact, the reverse is also true. Our ear brain combination cannot locate the source of sounds below 100 Hz.
Now, as far as what or who makes the noise: imagine, you and your significant other sing die same note. How can I tell whose voice is whose? A guitar and a piano So m pretty poor. The average specifications (specs) for Dolby stereo on a VCR involve frequency ranges of about 100 to 10,000 Hz. Better-made machines will occasionally offer frequency response as high as 12,000 Hz. If you are not an audiophile I will remind you that you can hear from about 20 Hz to about 20,000 Hz if your hearing is normal.
HARMONICS Obviously, Dolby stereo misses quite a lot of possible sound. Now, there are no musical instruments that will be “invisible" to your ears because the primary sounds of most instruments do not really reach into that range. Nor are there opera singers, singing at 16,000 Hz, whose voices you will not hear. For the most part, the frequency range from 12,000 Hz to 20,000 Hz is the range of “overtones" (harmonics), (If you are an audiophile or a musician, please bear widi me.) Harmonics and overtones do two basic things for us. They tell us where die music or sound is, and they tell us
(pretty much) what or who is producing die sound.
When we hear a sound, our brains tell us the approximate location of the source of that sound by automatically comparing the different versions of the sound as they reach us. When a sound is produced in front of us, we sense that sound directly, as it reaches our ears. We also hear how that sound bounces off of is so sophisticated that it can discriminate between reverberations as small as a millisecond (one thousandth of a second).
Our ears can also sense when a sound is stopped (literally, absorbed) by our surrounding surfaces. I am sure, if you close your eyes, you can imagine the The fact is that most people (including most audio video salespeople and even some desktop video pros) do not really understand Hi-Fi VCR sound.
K, ...... -Jt K!

• • difference between sounds in a small, relatively “dead" room
(wall-to-wall carpet, overstuffed furniture, Low ceilings) and
the way things sound in a large “live” or “hard" room, such as
a gym, church or auditorium.
In some ways, the higher the sound or harmonic, the more it tells us about the position of the source and our play die same note. How can I tell them apart? It is the harmonics produced by our voices, by instruments, by anything that makes a noise, that tells us who or what die noisemaker is. Hearing die complete harmonics produced by a voice or instrument enhances die pleasurability of the listening experience immeasurably. It is one of the major factors which make a difference between listening to a cheap portable radio and a fine stereo system.
There is also a third factor which affects our perceptions: those 'lost" sounds below 100 Hz. Louder sounds of approximately 100 Hz and below are not only heard, but felt. This enhances the realism of sound effects and music considerably. We usually do not even notice that we feel die sound unless it is extremely loud, but we do feel it. (If tiiis interests you, you might want to check out a book on psychoacoustics.)
But 1 digress...So here we are with Dolby stereo. It is a vast improvement over mono, but it is still not like in the theaters.
What we need is a way to improve the fidelity, or accuracy, of die sound. (By the way fidelity is from the Latin fidelitas-, meaning faithfulness.)
A GOOD IDEA So it came about that some very clever engineer, diinking back to the equation, greater speed + larger recording _(continued on page 70) ASDG's ScanLab View from the Inside by Peny Kivolotvit: If anyone bad told me eighteen months ago that ASDG would be a leader in color technology on the Amiga, I would not have believed them. It was two summers ago, and we were just introducing our general purpose inpuCoutput board, Twin-X.
I had gone to Atlanta for a quick tour of Comdex. I arrived in Atlanta with no hotel reservation, expecting to find lodgings on the fly By the way ibis was m y first Comdex After hoofing from hofeflo hotel for three hours. ("We're Sony. You should know heller than hying to get an itnre-

7Se bus 7saw in the distance late Comdex shuttle. Of su re i
- course, it wa&ffot Fj mnh’ a cab came up. And I jumped mi. At
that moment a man asked if I would not mind sharing the cab.
reluctantly agreed.
The fellow asked what I drought of die show. I replied that I had not been there yet, and that I was at the show only to meet a couple of specific people, and tiien would be on my way back home.
Seeing no I.D. badge on him, I asked if he was an exhibitor or attendee. He said ‘'an exhibitor'. I asked him how the show was going for him to which he replied. “Oh pretty well. I have been incredibly busy though. I had to give 54 press interviews yesterday.” Huh? Bing, bing, bing. Who is this guy?
Well, the man I shared the cab with was Bill Robinson, general manager of the Sharp color products division, and he was at Comdex to introduce Sharp’s new line of color scanners. The scanners, it turned out, interfaced to a host computer using the General Purpose Interface Bus (GPIB), which coincidentally was one of the first interfaces we were going to implement for our Twin-X board.
Well, we talked for a while. .And in our conversations, I learned tiiat Sharp would have liked to have had their scanners interfaced to the Amiga, Said tire gendeman, “But I don’t see how we can do that for at least two years". Ahem.
A short time after Comdex, a Sharp JX-450 color scanner arrived at ASDG’s building. We had thirty days to prove we could interface the device to die Amiga.
The first order of business was to design, prototype, and prove a GPIB module for our Twin-X board. Of course, we had not explained to Sharp diat the GPIB module did not actually exist at the time we talked about doing the scanner software. So the hardware engineers at ASDG worked a litde overtime.
Once the GPIB hardware had been developed, it became a software task to write die low-level routines which would control the GPIB bus and actually talk to the scanner. Of course, no one at ASDG had ever written any GPIB software before.
So the software engineers at ASDG worked a litde overtime.
Widi 15 days left on our clock we were set to start writing the code to actually control the scanner. After several days we actually got the scanner to talk to the .Amiga widiout it, die Amiga or both devices curling up in large and uncooperative ball.
In the time we had remaining, we were able to develop what became the Trial screen of Professional ScanLab ® and die rudiments of what was to become Professional ScanLab's fine screen. So everybody at ASDG worked a litde overtime.
This early version was crude. Very crude, in fact, if compared to what we are doing in Professional ScanLab and in ScanLab 100® (for die brand new Sharp jX-100 portable color seamier). We made amangements to have Sharp see the prototype system at AmiEXPO, Chicago (198S).
We waited anxiously for die man from Sharp to arrive, We did not know what he looked like, nor he us. We did know that one word from him, and ASDG's foray into color graphics would be over.
Well into die appointed day, a very lost looking fellow in a heavy' overcoat wandered by the booth. He was sort of walking and doing slow pirouettes, trying to take in the cacophony of bleeps and sounds. (In case you do not remember or were not there, .AmiEXPO Chicago '88 saw some fierce competition between audio digitizer manufacturers. We must have heard an F-14 take off from die U.S.S. America at full, realistic volume a thousand times).
He saw die ASDG name on the boodi and came in to take a closer look. There was a crowd around the JX-450, and when he saw it, he knew he was in die right place.
We showed him our prototype software. At that time we could not even render our own color pictures. We had three 4-bit plane IFF files out, one each for red, green, and blue, and tiien merged diem inside Pixmate. Crude. But it was enough to get die go ahead, and we got to keep die scanner.
Soon after AmiEXPO, we developed our own color palette technology and were able to render HAM images inside of Professional ScanLab. It was dien that we began to experience a now too familiar form of frustration. That of “Big Pixels and Litde Palettes".
Professional ScanLab was often being shown on the company MacII’s.
With a 1024 x 800 24-bit true color card (alias "Real Tiny Pixels and A Very Very Deep Palettd') die MacII scanner software literally changed nothing in the image in order to show' it, and the images looked great. We, on die other hand, worked our buns off to pick the optimal set of lS color registers which would milk the most visual accuracy out of each and every' one of our huge lo-res pixels. It was discouraging.
But on the upside, we found diat Professional ScanLab and the Amiga did have some small advantages. Like being able to perform a color separation 6 to 30 times faster than the best software on the Madl. Like being able to scroll around a HAM image as large as 5000 x 3000 without the user ever seeing any of those unsightly fringes along the left edge of the screen, (HAM bases the value of any given pixel on the value of the pixel which is to its left. When the pixel to the left scrolls off the screen, the pixel remaining must be recomputed.
When people think of scanning resolution, they often think in terms of black and white (1 bit) scanning.
But a color dot contains an incredible amount of information. In fact, if you represented the amount of information in a black and white dot as one inch, a 24 bit color dot would stretch just under 265 miles.
Consider for a moment that each time the screen shifts, a column 16 pixels wide and as high as the whole bit map must be recomputed. And, it has to be recomputed faster than the eye can pick up the intermediate, and very messy results.)
Oh, and while the HAM recomputation is taking place, also consider that we are paging the image in and out of CHIP ram and FAST ram, A solid month of 16 hour days was spent on the scrolling code alone.
Another issue was the sheer volume of data which comprises any 24-bit plane image. We calculated that the JX-450, if asked to scan its maximum area at its maximum resolution, would deliver 52 megabytes of data to the Amiga. So much for our fully decked out 8 megabyte Amiga.
As it turns out, die huge disparity between what the scanner can deliver and what die Amiga can handle without true virtual memory does not really impact die use of the scanner in color publishing all that much. We learned that most scanning applications require no more than 150 dots per inch as opposed to the 300 dots per inch of which the scanner is capable. Also, it is pretty rare that users need to scan all of an 11 by 17 inch area.
When people think of scanning resolution they often think in terms of black and white (1 bit) scanning. In black and white, 300 dots per inch is not close to being acceptable for professional applications.
But the JX-450 is a 24 bit per pLxel scanner, not black and white. A color dot contains an incredible amount of information. In fact, if you represented die amount of information in a black and white dot as one inch, a 24 bit color dot would stretch just under 265 miles.
We also learned that the required input resolution (for good results) is dependent upon die relative size of the input image versus the output image. For instance, if you print something one quarter the size of die original, you can cut in half and get the same results.
Given what wre learned, we discovered that an 8 megabyte .Amiga can serve almost all of the needs of a color publishing house. Of course, if you are lucky enough to have a 32 megabyte 32-bit memory board on your 68020 or 68030 board, you can do more.
Once Professional ScanLab started shipping we were able to rum our attention to the next small problem. That of "Now that we can generate these really cool 24-bit images and 24-bit file separations, who can process them?" We found the answerto be, “no one”.
We knew how much work went into getting the 24-bit color processing right, and after talking to Gold Disk, we confirmed our suspicion diat they would not have die resources to develop the necessary 24-bit suppoit that would allow our images to be directly imported into Pro Page. The question then became, "Howrdo we lend Pro Page our ability7 to process 24- bit color?” The answer came to me during a University of Wisconsin basketball game (the Badgers won, by the way). Have Pro Page insert the key informadon that we would need in PostScript comments imbedded into dieir color separation
output.
That way, we could edit the output of Professional Page as a post-process. We could “strip out" the 12-bit color separations done by Pro Page and “strip in” the 24- bit color separations perfomied by Professional ScanLab. ReSEP was born.
An interesting postscript (oh dear, those puns do creep up silendy don't they?)
To the story of ReSEP is that several months later the publishing software giant, Aldus, introduced die Open Pre-Press Interface on the MacII. Opi is a system whereby DTP software imbeds comments in their PostScript output so that other programs can key in on them. Sound familiar?
The focus of Professional ScanLab has thus far been the printed page. Many of our customers have asked us for improved rendering capabilities for the purpose of displaying images on the Amiga’s screen.
Recendy we have had die opportunity to create what we hope might be one of the finest image rendering engines yet produced for the Amiga. Called ScanLab 100, we hope diat the product will be shipping by the time this article hits the streets.
The focus of ScanLab 100 is to generate the finest rendering possible given the limitations or constraints of die Amiga's display hardware. We have included some sample images with this article to show you how far we've come with ScanLab 100 towards getting die most out of the Amiga’s display.
Pioneering the use of 24-bit color technology on the Amiga has not been easy. .And, it certainly has not been widiout cost. Professional ScanLab, ReSEP, ScanLab 100 and our other color products are the work of an extremely talented and enormously underpaid team of engineers.
It's been my pleasure and privilege to work with them.
In all we have written, approximately a quarter of a million lines of color processing code over the last eighteen months.
This effort was and is necessary to give the Amiga a credible presence in the color publishing marketplace. To us, the idea of the world's most capable, inexpensive color computer not being at the forefront of color publishing is repugnant.

W e received several letters with information on problems and workarounds, as well as a couple of upgrade notices for commercial software this month.
Bug Bytes The Bugs and Upgrades Column by John Steiner Robert Singleterryjr. Of Idaho Falls, ID ishavingaproblem with both RAD: and the ASDG recoverable RAM: disk. RAD: gives read write errors and KEY errors. The ASDG device has similar problems. Both these devices work reliably in most Amiga computers, so the finger of blame seems to be pointing to Mr. Singleterry's hardware which consists of an older Amiga 1000, a 2 MB MicroBotics memory board, die Amazing Computing 5 MB memory modification (AC V2.1), the grounded PAL modification, and mo floppy drives.
If you have run into similar problems with either RAM: or RAD: disk, or if you have found a solution or workaround, please let me know, I will pass the information along to Mr, Singleterry.
Peter Orvis of Arlington, VA reports of a problem with the September 29, 1989 update of WordPerfect. The PRINT program does not subtract one inch from the top margin setting when the “Hand Feed” mode is selected. The result of this is diat paper in a hand-fed printer, which is automatically or manually fed so that the top edge is under the bail, will be fed further in accordance with the top margin setting, just as though itwere continuously fed paper in a tractor printer. This fault was not present in previous versions of WordPerfect. The obvious workaround is to manually reduce the top
margin by one inch, or whatever is required to make the print function handle the top margin correctly.
Paul Olson of Germantown, MD sent a copy of a rather lengthy letter he mailed to Electronic Arts regarding a problem with DeluxePaint Til when used with the Cal- Comp ColorMaster. The symptoms of the problem are as follows: Immediately after loading the paper, the plotter is instructed to advance tire ink roll (a cellophane roll with three wax-based ink frames: yellow, magenta, and cyan) to tire next yellow- frame. The plot is then generated. The plotter is again instructed to advance the ink roll to tire next yellow frame. The plotter is never instructed to eject the paper.
If multiple copies are requested, the additional copies are simply printed on the same sheet. The only way to eject the paper when using DeluxePaint III to generate the plots is to press the plotter eject button when the plot is completed.
Mr. Olson researched the plotter manual and determined that die developers of DeluxePaint III assumed that all plotters use form feed characters to eject the page. The ColorMaster uses the end-of- transmission character. As a result, the form feed characters cause the printer to use two sets of color frames for each plot. At over $ 3-20 per frame on the color roll, tire waste of a frame for every picture is too expensive to ignore. If you have ever had a problem combining several software products provided by different vendors, you will immediately identify with what happened next.
Mr. Olson spoke with Electronic Arts, who told him that since Commodore supplied the driver, it was their problem. He called Commodore, and they told him it was CalComp’s problem, since they wrote the driver. CalComp pointed die finger at Electronic Arts, and said drat it was dreir problem.
Mr, Olson found that both Photon Paint and Digi-Paint 3 use tire CalComp driver to drive the plotter correctly, and his current workaround is to work in DeluxePaint III and print from Photon Paint.
Mr. Ed Gwynn, the quality- assurance engineer for Electronic Arts, seemed to agree with Mr. Olson diat the problem was caused by the way the program handles plotter devices radier than in the driver itself, as other programs were using the CalComp driver correctly. Mr. Gwvnn said that the problem would be forwarded to DeluxePaint III author Dan Siiva for correction.
Walter Strickle r of Boulder, CO wrote with several potential problems for owners of M.A.S.T. Tiny Tiger hard disks. Mr. Strickler reports that older A1000 units have capacitors between the signal lines of the parallel port and ground. Since the Tiny Tiger plugs into die parallel port, this can cause problems.
A call to M.A.S.T. revealed the solution immediately: remove the capacitors.
They recommend removing C33-C35. Also suggested was removing all the parallel port capacitors (C23-C35). Removal of the capacitors solved die problems. In conversing with technical support personnel at
M. A.S.T., I found that they do not recommend the removal of
these capacitors.
Rather, they recommend replacing C33.
C34, and C35 with 100 picofarad capacitors.
The second problem Mr. Strickler writes about concerns the transparency of the parallel port connection. M.A.S.T. claims that data to the printer is passed through the Tiny Tiger transparently. This is true if you ignore multitasking, which is a major reason to have an Amiga, if you send data to die printer from one process while accessing (even reading) the hard disk from anotiier process, the printer hangs.
The technical support person at
M. A.S.T. said he never heard of any problems with the system
when multitasking, and he would like to have more details on
which programs are being nan when die system seems to hang up.
The moundist entry for these 50 MB units had a defective entry
which caused an unusual problem.
Once the drive became over 50% full, certain files would be trashed when copied to the drive. There was no warning, die data tiiat was written was just wrong. If enough files were removed to go below 50% full on the drive, then recopying the trashed files worked just fine.
A representative from M.A.S.T. told Mr. Strickler that Seagate said the 50 meg drives contained 6l4 cylinders, so that’s what they set the moundist entry' for ‘highcyl’ to. They said the real number is 607, because some of tiiose cylinders are reserved for SCSI internal use. When the disk becomes over 50% full, the hashing al- goridim becomes more random, and die data for files with certain names sometimes ends up in the reserved area.
The solution is to back up the drive and reformat with highcyl set to 607. Actually, you may have noticed an inconsistency in this response. They said that they thought die drives contained 614 cylinders and so they set highcyl to 614. The latter would imply 615 cylinders total (including a lowcyl of 0), and Mr. Strickler was suspicious of die 607 number. Is that 607 cylinders or a highcyl value of 607?
Not having any documentation on die drive mechanism, and not thinking it was wordi another call to M.A.S.T., he decided to play it safe and set die highcyl to 606 (for a total of607 cylinders). This has worked just fine, as the problem with file trashing has not occurred since, even though the drives in question are well over 50% full.
In my visit with the technical support people at M.A.S.T., the people I talked with said that tiiey do nor remember having a problem like diis and they requested complete details on the problem. I promised to send them a copy of the letter I received for their evaluation, and they promised to reply to the problem once they had had a chance to more thoroughly determine what kinds of problems Mr. Strickler was having.
As I received the correspondence on this comment only a few days before deadline, I opted to comment on the possible loss of data widi diese drives and advise, if you have the Tin)' Tiger 50 MB drive, and the moundist highcyl entry is 614, that you may incur a potential loss of data. You should contact M.A.S.T. about this. Next month 1 will print any information they provide as diey will have had a chance to study die problem.
Overall, Mr. Strickler thinks the
M. A.S.T. Tiny Tiger is a fine piece of hardware. He comments
that it is inexpensive, quite fast for a parallel
port-attached disk, and is portable between current Amiga
models.
Also in this month’s mail bag, I received a letter from Gregory Epley, President of Second Sight of Lexington, NC. He writes tiiat Version 1.3.0 of ANSIEd, the ANSI Screen File Editor, is now available as an upgrade to all registered users. The upgrade fixes several major and minor bugs, compresses space gaps for reduced file size and 15-45% faster displays, and optionally stores icons for files. The interface and installation procedures have been greatly improved as well. Registered users can receive the upgrade free by sending tiieir original master disk to Second Sight.
Electronic Arts has released De- luxeVideo III, a major upgrade to one of the first truly powerful animation programs.
The latest version requires 1 MB and two disk drives and supports all Amiga IFF modes including HAM and overscan. SMUS andS5VX files, Arexx, MIDI, and Supergen support are also provided.
The program also works with De- luxePaint III. To upgrade from previous versions of DeluxeVideo, send $ 49-95 + $ 7.00 shipping and handling (CA residents must pay $ 4.20 sales tax) along with die front cover of the manual to Electronic Arts DeluxeVideo Upgrade Offer, That’s all for this montii.

tl& C (froup "Static" Variables by Stephen Kemp In past
articles, we have discussed different variable types and
ways to define those variables. Primarily we have focused
upon local variables (those defined within a function) and
global variables (those defined “outside” of functions)
which are available to the entire program. This month we
will discuss a modifier for variable definitions, which
makes “static" variables, and how these relate to the
normal declarations.
Global variables (sometimes called external variables) can be referenced by any function within a program. Additionally, a global variable retains the last value assigned to it diroughout the remainder of the program (or until assigned again). These types of variables are generally used for information that needs to be available for numerous functions throughout the program and eliminate having to pass the variable as a parameter. At any given point, any function can reference a global variable to determine the value that was last assigned to it, or the function can assign a new value for
other functions to reference. Finally, most compilers include code that assigns a global variable a “zero" value at the start of a program.
Local variables, on die other hand, can only be used by the function that defines them. And, unlike global variables, die value of a local variable is undefined when die function begins and must be assigned each time. Local variable space is assigned to a function each time the function begins. The space used for local variables is assigned from an area of program memory called the stack. Your program’s stack space is usually the same (constant) size diroughout your program. When a function begins the space necessary for local variable definidons is assigned by adjusting pointers into the
program stack. At the function’s exit, the stack space used by local variables is then reclaimed (pointers readjusted) and available for subsequent functions to use.
The constant use and reuse of the stack means that when space is allocated at the beginning of a funcdon, you cannot rely upon the value your variables will contain. Unlike global variables, die compiler will not include code to clear your local variables. Global variables only have to be cleared once at the start of the program; a minor amount of overhead. Clearing local variables would require diis overhead in every function that declares variables. Also, many of die functions that you write will have to turn around and reassign a value anyhow because you probably did not want zero. Radier
than penalizing your program's performance, it is left to the developer to ensure that initialization is done properly. In fact, many compilers will issue a warning if they diink a Local variable is being used prior to initialization. Usually die -warning is something like, “Warning: Possible use of variable before definition.” There is one last danger I should mention about local variables declared by functions. Since they only have “space” while the function is active, it is important to NEVER return a pointer to a local variable from a calling function. Do you see the danger here?
Remember, the stack space is likely to be reused by subsequent function calls. Therefore, the pointeryou return may at first point to what you intended but will soon be undefined. It is okay to pass local pointers “down" to functions you call, but never “up” to those diat called you.
Using the stack for local variable space, however, is an important feature. Each time a function is called, it first allots die variable space it requires. That is why it is possible to have a recursive function. Each invocadon has its own variable space and will not interfere widi die former's “position”. Likewise, it is important to realize that reusing the variable space is more memory-efficient. Carrying around all of your variables as globals would make you quite a memory hog.
Now that we have had this refresher on where variables are kept, it is time to introduce a new modifier that limits the “scope” of a variable. The word “static” can be used as a modifier to variable declarations. This modifier can be used on any variable definition and allows you to bend the rules set forth in the previous discussions of global and local variables.
Here are a few example definitions: static long recnum; static char last_message[803; static MYTYPE lvar; * where MYTYPE is a structure typedef* As you can see, the static modifier is not difficult to use. It merely precedes the variable type indicator. Lt can be used on either variables declared within or outside a funcLion. I did not say local and global variables because the static modifier changes those definitions.
When a static variable is declared outside of a function (like a global variable) it makes what you might call a module-global.
The variable is only global to those functions declared within the same program module (or file if you prefer). Your functions in the DR. OXIDE SLICES PRICES!

w cable S129.99 same module will not know the difference
between a module- global and any other global variable.
However, outside of the declared file, the module-global
variable is no longer defined. This means we can limit tire
scope of a global variable to a given file.
In all other respects, a module-global variable is treated like any other global by the compiler and is usually initialized to zero as any oilier global variable would be at tire start of your program.
Static local variables do not have to limit the scope of reference because local variables can only be referenced by the function that declares them. So, what does a static local variable give you? It gives local variables more permanence. Rather than allocating tire space each time the function begins, your C compiler ¦will assign the static variables space from the regular memory (again like a global). This means that your variable will retain tire last value assigned to it no matter how often the function that declares it begins and ends. In a sense then, the variable is a global variable
that has a limited scope to one function.
The value of static variables lies in the fact that often your functions need to know former values, yet you don’t want to confuse the variable with your global ones. Since static variables are limited in scope, they can be given the same names in different areas widiout interfering with each other. This fact can help to ensure that your variables have useful names without causing a conflict with subsequent function (or module) declarations.
Wrapping up this discussion, I should mention that you can also declare static functions: static long get_number(var) These are declared similarly and have the same effect as module-globals. The function’s scope is limited to a single file. Those functions declared within the module can reference the function, yet it will be invisible to those in other modules. This too allows you to assign useful names to functions without conflicting with other static declarations in other modules.
This has been a brief introduction to the world of static variables. If you still have questions, get out your favorite reference manual and see if the authors) can fill in the blank spots.
Then get out your compiler and try a few experiments. You can learn a lot from experimentation.

• The Cycles STELLAR CRUSADE First on the list this month is
another Amiga entry' by Strategic Simulations, Stellar Crusade.
While the interface is still not what it should be, it is an
improvement over Star Command, and it is at least as enjoyable
to play as Red Lightning, Strategics WWI1I game.
Sometime in the far future (isn’t that when ail these things take place?) Two small empires are vying for control of a rich group of stars in a remote arm of the galaxy. The Terran Navy had kept the peace in the area for many years, but with their departure, the People’s Holy Republic declared a holy war against their bitter rivals, the Corporate League. Filled with an intense hatred of capitalist ways, tire Republic used their bizarre religious combination of ancient Biblical and communist -writings to justify one final act to clear their corner of die galaxy from the scourge of free
enterprise. Only the ‘-timely" assassination of the man who had declared the Jihad, First Elder Grisham, gave the League the few years respite they needed to prepare for the massive assault that was to follow.
Rescuing Sandy the cheerleader: Litcasjilm’s Maniac Mansion.
Vyingfor control of a rich group of stars in a remote arm of the galaxy: Strategic Simulation's Stellar Crusade.
Stellar Crusade combines elements of economics, exploration, production, and combat into a grand strategic struggle for diis sector of space. While the entire game system would be a bit much for the starting player, the rules are designed to gradually ease the player into the mechanics of the game bit by bit. Each scenario covers a different aspect, and if played in die proper order, they will quickly teach the player the mechanics of play.
Play begins widi Operation Gold River and Plan Jericho. These two batdes only last a fewyears and are strictly combat exercises. All production is automatic, and the pi ayer only needs to be concerned with maneuvering his fleets for confrontation with the enemy. Operation Gold River is very simple, since the only goal is to control Brotherhood, die Republic’s home planet.
Plan Jericho is a litde more extensive, and points are given for control of eight key planets along their common borders.
The next section covers exploration and colonization, which is vital to winning the longer contests, since each side only begins die game with two or three planets under their control. Appropriately named, Exploration covers the first five years of the war, and the heady wave of expansion that characterized the chaotic beginning of the war.
Finally the player can tackle the game’s economic system. While it is not really that complicated, many decisions must be made to successfully wage war in this dark future. The four remaining scenarios combine all these elements together to challenge even the experienced player. Two versions of The War are included, one historical and the other an alternate order of events where First Elder Grisham was not assassinated and, therefore, had personally launched the fighting. Each runs about 50 turns until one side or the other is subdued.
The last two scenarios are evenionger affairs. The Short Campaign is only short by comparison and will typically run around 75 turns, beginning just after the initial period of chaotic expansion and after things have had a chance to balance out. The Long Campaign is the grand daddy of them all, lasting about 100 turns and including the period of initial imbalance. Before fighting die war in earnest, the players must balance out dieir productions to optimize dieir chances of winning.
Stellar Crusade combines elements of economics, exploration, production, and combat into a grand strategic struggle... Stellar Crusade can either be played solo, against the computer, or with two human opponents. If a solitaire match is chosen, the human player always has command of the League. I suppose the designer thought the computer was more “religious” in its outiook.
The player has control over many aspects of gameplay, suchasthedifficultyof the computer player; whether realistic command and control will be used; whether fog of war constraints will be used; and whether resupply will be done for the player. In the later campaigns, players can even design dreir own ships to complement dieir own playing style.
As I mentioned before, the graphics in the game are very similar to that of Strategic's other releases. The map of the local group takes up the upper half of the screen and uses an interesting 3D-like display to show the location of each system. The base plane of the galaxy is drawn slighdy tilted, with colored dotted lines indicating how far above or below die plane each system lies.
This was a nice touch and looks reasonably well.
Unfortunately, the rest of the graphics fall short. Even the title screen is not very clear. The main problem is the overabundance of text. I am not sure tiiat it could have been completely avoided, but most of die information used in the game is displayed in a straight text manner. Because there is so much information to display, the game has many screens packed witii information, which can be tough on the eyes.
Where they tried to add graphics, diey often missed the mark.
Production capabilities do lend themselves well to the pie charts used in the planetary displays, but the use of icons for population figures is counterproductive, and it is one of the places text should have been used. Basically the system works as follows: Each man-shaped figure represents 1000 people, widi underlining used for powers of ten. Thus 287,000 wouid have two people with two underlines each, eight people widi one underline, anc! Seven people without adornment. A simple “287" would have been much better and easier to read.
The different ship types are rather crudely drawn and simply use a common front and rear end, filling in the middle sections from a palette based on dieir structure.
I suppose this might make you tiiink I am totally down on the game. On the contrary, it has great potential and appears to have a solid computer model underneath, but the difficulty of the interface again hinders play. I sincerely hope SSI will listen to its users’ feedback and start coming out with games that do more to utilize die extreme power available in the Amiga, instead of the half-hearted attempts they have made so far.
The price is a bit steep, but since the competition is weak, die hard-core space combat warfare player may still want to pick up a copy of the game, especially if they can find it at a discount.
MANIA C MAN SION Next on die list is a game that has been out for a while on die Amiga, but since it is a good game, and it has not been covered, I decided to cover it here.
Maniac Mansion is a fairly bizarre role-playing game unlike any odier before it. Originally released in 1987 for the Commodore 64 and Apple II personal computers, the game has been greatiy improved and brought up to the standards of the 16-bit machines. It is not perfect, but it is a good start in the right direction, and did lead to several follow-on games, two of which 1 will mention briefly later.
A demented scientist has kidnapped Sandy, everyone's favorite cheerleader, and has hidden her away in his secret laboratory in the basement of an ancient Victorian mansion. With the help of his devious assistants his wife, Nurse Edna, son, Weird Ed, and several unearthly pets he is preparing his victim for irreversible brain surgery, ending forever her hopes of becoming homecoming queen.
From a pool of eight of her fellow students, you must assemble a three-person rescue team, navigate die hazards of the house, and free her from imprisonment.
The game has a movie-like feel to it, dianks to die Lucasfilm staff. In addition to hilarious sight gags and smooth horizontal scrolling, “cut scenes" are used liberally throughout piay to show the players what is happening “back at the ranch”, keeping them up-to- date on the whole system. The game is fairly easy to play since it uses a “point and click*’-type interface. It is very easy to play the game with only a mouse, tiiough many of you will prefer to keep one hand on the keyboard as an alternate way of entering many of the one keypress command equivalents used during play.
This ease of play does not mean the game is shallow. On die contrary, die game has so muchdepdi that it will take the player a long time to actually solve the game. The available commands provide for Lays-.- front A-cir Approxirutf ?!

- M am® a wide range of options, and nearly anything can be
examined, encouraging the player to poke around all areas of
the screen. In addition, five different endings await each of
the possible fourteen teams that can be used to rescue our
beloved cheerleader. Do not get too overwhelmed; all the
puzzles are solvable, though some will require significant
thought. And remember, think bizarre!
The graphics are a semi-3D view, reminiscent of the Space Quest series, and the on-screen characters move around the screen fairly convincingly. The graphics may not do everything, but they are good enough that they get out of the way and let you play the game.
While the game manual is only about ten pages long, the documentation includes a poster resembling the school’s bulletin board. In addition to its humorous aspect, this poster contains many clues to overcoming the obstacles that will face the player in his attempt to free the cheerleader and save the world! (You always have to save the world in these games, right?)
Maniac Mansion is a quality production and shows Lucasfilm’s touch. Gameplay is challenging and will provide many hours of entertainment. The games replayability also adds to its value. This game is a must for those who enjoy adventure-type games.
Two similar games were more recently made in the same series, both enjoyable - Zak McKraken and the Alien Mindbenders, and Indiana Jones and The Last Crusade: The Graphic Adventure. Both also add a few new features to the already good game system.
The graphics are not as good as the original though. Some of the feeling of depth is missing, and these cars seem rather plain.
I realize that they may not have been as sleek as current sports cars, but they did look nice when polished up and cruising the town.
The cars also sound different, a nice feature. A slightly rougher rumble is used as MUSCLE CARS Nostalgia is a hot topic nowadays, and in attempt to cash in on that craze, Accolade has released Muscle Car, a data disk for Test Drive II: The Duel. This disk covers five classic cars popular throughout the Sixties and known for their "muscle".
The car speeds along, reminiscent of the era.
This is a nice improvement.
On the whole, the data disk is OK. If you really enjoyed Test Drive II, you might want to add this to your collection. If you do not play it a lot, it is not worth digging out just to play this disk.
ETOR IS I ON Vrroomnt: The Cycles by Accolade.
Included on the disk are die 1963 Corvette Sting Ray “Split Window'” Coupe, the 1968 Shelby GT500 Cobra, die 1967 Pondac GTO, the 1969 COPO 9560 ZL-1 Camaro, and the 1969 Dodge Charger Daytona. These were true All-American powerhouses.
While not as powerful as die Ferrari F40 or Porsche 959 that come with the main program, diese cars have their own unique features and can be fun to race against each odier.
THE CYCLES The last game this month is The Cycles, also by Accolade. As you may have guessed, this is anodier in the growing field of motorcycle racing games. The program features races on fifteen tracks throughout the world. Each track is in a different country' and features a different layout. Some are a series of gradual curves with the ocassional ability to go flat out. Others are extremely curvy and constandy require preparation for an upcoming twist or turn.
Three different cycles are available to race: 125cc, 250cc, and 500cc. The higher the number, die more power the machine has, and each cycle will race against others of its own class. The game also has five difficulty levels, from Beginner, with its automatic shifting and forgiving drivers and course all the way up to Pro, where you will face of?
With die best, and put your skill to a real test.
Three different opdons are available during play. Pracdce laps can be taken on any course to learn its particular curves and twists.
The next step is usually to race the same track.
After completing a qualifying lap, you are put head to head with nine other top- qualicy racers who want to race you into the ground. A complete race can consist of anywhere between 1 to 99 laps, at your option.
After you have mastered each course individually, you will want to go for the whole ball of wax on tire Championship Circuit. This places you, and the same nine drivers head to head on each track in succession. May tire best racer win.
The bottom of the screen features the view over the front of tire motor cycle, which is rendered in good detail. The actual course is rather sparse and features little detail in the w'ay of scenery. Along the top of tire screen are three useful information displays. An overhead viewr of tire current course is shown in tire upper left comer, the rear-view mirror of your cycle is in the middle, and an information readout, with your current speed, lap time, and race time is in the upper right comer.

O. BOX 1453, COLLEGE STATION. TX 77841 Hither tire joystick or
tire keyboard can be used to control tire cycle during the
race. However, as is common with games of this type, it can
take a while to get used to the controls. New users will often
find themselves weaving back and forth from one side of tire
track to another, even at tire easy level.
This is tire game’s greatest failing.
When I first began playing, I could not pass anyone in a real race, even at the easiest level, since I kept going off the road. I suppose this is realistic, but it is my view that games of this type should let even a new' player do well at the easy level. I do not expect to win instantly, I just wrant to do well, and have a reason to continue on into the game. The higher difficulty levels should be where the challenge comes in.
I guess I have yet to find a racing game that has a really good control. They all tend to jump back and forth pretty easily, a bit too responsive. Maybe a real steering wheel device will come out at a reasonable price.
Until then, only true racing game fans, who need another fix should buy The Cycles. There is simply not enough here tc make it stand out. Compared to other cycle racing games, it is OK, but there are other racing games that are better.

Analog t0 Djgjta| Conversion by John Iovine 1JB7 on die Amiga parallel port. Previously, we used parallel interfacing. This is easily implemented by POKEing a control number in die Data Direction Register (DDR), then reading or writing to the port output in whatever combination is required by the user.
Parallel interfacing transmits or receives eight data bits (see Figure One) simultaneously on eight parallel lines (PB0- PB7) which we call a data bus.
This is what we have experimented with on the Amiga’s parallel port. Figure One details die PB lines off die port.
To read the binary number you add the decimal values represented by eadi bit. The binary number in this example is “01100101" This binaiy number translates to the decimal value (1 + 0 + 0 + 8 + 16 + 0 + 6-1 + 0) of
89.
Figure Two shows how the same information can be transmitted or received over a serial line. The figure should be read from right to left. The “most significant bits" (MSB) are transmitted first. A serial bus need only consist of two lines. As its name implies die informadon is transmitted serially, that is, one bit at a time. The first bit transmitted or received is bit =7.
The clocking line correlates the precise moment to receive or transmit data on the line.
Amiga computers have a built in Serial Data Register (SDR) and clocking (CNT) line on die parallel port that can receive or transmit serial data in such a fashion. This gready simplifies our programming task.

as eidier an input or an Tills month we will build an analog to
digital (A D) conversion circuit. Analog to digital conversion
circuits are very useful.
They allow the computer to interpret or analyze an input voltage signal. The voltage signal can be from any number of different sources and can be digitized for use or for display by the computer. Some more familiar examples are sound and video digitizers. The simple digitizer we will build allows the computer to monitor the real world environment.
Depending upon the type of sensor (transducer) we use, the circuit can measure and or delect light, heat and some toxic gases.
The A D converter we will use is a serial A D chip. This is very easy to interface to die Amiga via the parallel port. You may wonder why we are using a serial A D chip on die parallel port. The Amiga has a functional bi-directional serial data register and clocking line on die parallel port. This increases the options as far as interfacing with the computer, and it is real easy to do.
For those of you who may have missed the first installments of diis series, I will review some preliminary information so you won’t be completely lost in the description of the circuit or its operation.
The basic definition of binary signals: a binary “1” is equal to approximately 5 volts, a binary “0" approximately 0 volts. Binary- signals can be inputted to or outputted from lines PB0- m Circuit C2 Circuit Cl Figure Four In addition, notice the three wire labels (A,B,C) placed on die tliree wires to die pot. 1 placed this notation diere so you the computer. One property of analog signals is that they are infinitely variable between any two points. Take as an example the possible voltages existing between 1 volt and 2 volts. The possible number of analog voltage measurements between these
two points is infinite. It can have virtually any value, such as 1.1 volts or
1. 0000001 volts' or 1.00000000000000001 volts. As you can see,
voltages can vary by infinitesimal amounts. The same is true
for all natural phenomena such as time, temperature, gravity
etc. DIGITAL CONVERSION The digital conversion of an analog
signal occurs in discrete, predefined steps. A simple example
is an electric light that has two states, on or off. A rising
voltage, plotted digitally against time, would not plot as a
straight line (analog signal), but would jump in increments in
a staircase fashion (see Figure Two).
The chip we are using has an 8-bit resolution. This means it can output values 0-255- Because the resolution or step value of an analog signal is infinite, and that of digital conversion is limited to 255 discrete values (in a 8-bit chip), Chicago land’s Amiga software, hardware, and repair stores at* At* T* *T* *t* *• t* *t* *T* At* At* At* At* At* * t* at*

$ Staffed by Amiga users $ Pull selection of books, magazines & peripherals, including imported software Wheeling 708-520-1717 Chicago 312-338-6100 Hanover Pk 708-837-6900 conversion errors do occur. These are called quantization or “rounding off’ errors.
Lets look at this a little more closely.
If our chip is measuring voltages between 0 volt and 5 volts, it has a resolution of 5v 255 steps or .0196 volts per step. If a voltage varies from one step to another by less than .0196 volts, it would be rounded either up or down to the nearest step. This rounding off to the nearest step is called cjuantizalion error.
It also follows if we are reading a number from the chip, say decimal 100, we can use that to calculate the voltage being input. 100 x ,Q196v = 1.96 volts or (approximately) 2 volts.
SERIAL A D CONVERTER CHIP An analog to digital converter does exactly what its name implies. It reads an analog voltage then converts it to the proportional digital (binary) value for use by the computer. In our case, this digital value is transmitted serially into the computer.
The chip we are using is an 8 pin chip, some of its capabilities are as follows, max 40,000 sample: per second, internal clock and 8-bit conversion resolution.
CONSTRUCTION Construct the circuit on your experimenter's breadboard. As shown in Figure 3, a 1 OK potentiometer is inserted between the +6 volt line and ground (pins 1 and 4). The wiper of the potentiometer is connected to pin 2, analog input of the A D chip. This is a testing circuit for you to test the construction and the program.
CNT line by itself to provide the clocking pulses but this would require us to use the built in timer. We do not want to use this timer at this point. The timer will be used in other interfacing projects where we will demonstrate the numerous functions it is capable of performing.
PROGRAM Type in the program and run it. Vary die control knob on die pot and observe the results on the screen. The numbers represent the approximate digital equivalent of the voltage on pin 2. If you have a volt-meter handy you can connect the meter between pin 2 (analog in) and ground to verify the correlation of volts to the digital readout. Remember, your voltage step for this circuit is 6v 255 = .0235 volt per step. (Please see Using on page 62.)
Can see how simple and easy it is to connect the transducers into the circuit. The transducer schematics also have their respective wires labeled showing the connections into the circuit.
By looking again at the schematic and the program you will notice that pin 2 on the Amiga port (PB0) is used to provide the clocking pulse both to the chip and the CNT line on die port. We could also use the Figure Three RESOLUTION Although the resolution is fixed at 8 bits (255 steps) the voltage span being measured can be adjusted within limits using the Ref+ (pin 1) and Ref- (pin 3)- See chip pin out, A D chips on die market are identified by their resolution and interface method. Most A D chips are parallel interfaced and these can also be used with die Amiga parallel port. The common
resolutions available are 4,6, 8,12 and 16- bit resolution. Typically the cost of a chip is directly related to its bit-resolution and Thermistor Graph NTC Negative Temperature Coefficient A Temperature Figure Five conversion speed. The higher the bit- resolution and the faster the chip the greater the cost. 1 would advise sticking with 8-bit conversion resolutions unlil you have more experience working with these types of circuits.
TRANSDUCERS By substituting different sensors (transducers) for our testing pot, we can have die computer sense and measure light, heat, or anything else that a transducer can be made to detect. The three transducers we will work with are all variable-resistor types which will detect (separately) heat, light, and toxic gas. As each transducer detects its target, its resistance will change. This will cause a corresponding change of voltage across the transducer. This, in turn, will be noticed as a change on Pin 2 of our A D chip and will be displayed in the same way that turning the pot was
previously displayed.
LIGHT Cadmium sulfide (CdS) photocells, (Radio Shack PN* 276-1657) respond to the intensity of light that falls on them. Their resistance is greatest in complete darkness, and decreases in proportion to the light made available. Examine Figure Four Cl.
This shows die simplest method of connecting die photocell into die circuit.
The disadvantage in this particular circuit is that we are utilizing just one half (128-255) of our resolution (0-255). We can easily correct this situadon (see Figure Four C2 by adding two resistors. These two resistors make a voltage divider diat changes our REF- from) 0 volts to 3 volts.
This in turn changes our volts per step (ref+ minus ref- = ref voltage) 6-3 = 3volt. Using the new ref voltage we get 3v 255 - .0118 volts per step. With circuit C2 we are reading voltages between 3 volts (ref-) and 6 volts (ref+). This gives us full scale operation with the photocell.
Nov.' that we have a method of measuring light intensity, what are some applications for this device? If you are a photographer and do your own printing you could use this as an exposure meter for your enlarger. In the high-tech end of applications, a spectrophotometer is possible. Spectrographic analysis is a method used by sciendsts to determine the composition of unknown compounds. This technology is also responsible for determining the composidon of the sun and stars.
Templicity HEAT To measure temperature simply replace the photocell with the heat transducer (thermistor) in Figure Four C2. The thermistor is an NTC (negative resistance coefficient) type, which means it decreases its resistance as the temperature increases. See Figure Five. Resistance at 25 c 7605 a7- I 2 3 6V -VZ- Pins 1 & 3 imemaliy connected Pins 4 & 5 internally connected Figure Six degrees C (77° F) is 10,000 ohms. Maximum operating temperature is 150° C (302°F).

Change tire temperature scale and improve its response in the 0° to 120° F range, replace Rl with a 47K resistor.
Note: Although we are changing the reading range of temperatures by changing the resistor Rl, the volts per incremented step and the voltage reading range (on pin
2) remain the same. The only way to adjust this is by changing
the voltage divider resistors. If you should decide to change
the voltage divider make sure to remain within the range
detailed in the spec sheet and pin out description.
Calibration is necessary before using this sensor for any critical operation. One method of calibration is to submerge the sensor first in ice cold water then in boiling hot water marking each readout. The first number obtained is the equivalent of 32°F, while die second is 212°F. The most obvious application is an electronic thermometer and thermostat control.

Are using a 7805IC. The 7805 resembles a transistor but it is actually a 5 volt regulator.
The 7805 will provide a 5V voltage source for our circuit from any number of battery voltages. You may use this regulator in the main circuit to trim the 6 volt power to 5 volts (to keep the voltage closer to the design specs for the A D chip).
Examine Figure Seven. Pins 2 and 5 of the gas sensor are connected to an internal heater coil. Pins 4 and 6 of the transducer are internally connected as are pins 1 and 3. When you make your solder connections to the sensor you need only Canadian Software Developers Introducing: PSFont... ...the Adobe Postscript' font down- loader tor the Commodore Amiga'.
PSFont allows you to tap into the many font styles currently available to the MS-DOS community.
PSFont allows the Commodore Amiga Desktop Publisher to download Adobe Postscript fonts to an Adobe licensed Postscript printer using the MS-DOS file format.
PSFont is designed with flexibility in mind, able to download multiple fonts, through both serial and parallel interfaces, it is only limited by the amount of exisiting memory on the printer. Ease-ol-use is emphasized by full cli, workbench, and TASS* support.
Finally this obstacle in the Amiga DTP market has been hurdled.
Dealer Inquiries Welcome!
Connect to one pin of each pair. Polarity isn’t important for either the heater coil or sensor, any way you connect the wires the unit will function properly, You maynotice that die sensor feels quite warm when operating, don’t be alarmed, diis is normal and is a result of the internal heating coil.
Change R1 in Figure Four C2 to a 47K ohm resistor and connect the circuit as shown. Since die transducer has been in storage prior to your receiving it, it will require an initial 2 minute warm up period.
This warm up period will decrease with use. After the warm up period has passed you can Lest the sensor with a number ol household items. I first used a butane gas lighter, by releasing gas by the sensor (unlit), the sensor reacted by immediately jumping from a base line of 0 to 255. By breathing on the unit it will detect the carbon dioxide you exhale. You can test and experiment with other items such as cleaning fluids. You can use the toxic gas sensor for an automatic ventilator control or a home gas leak detector and alarm.

AMIGANET '' be Firs True Amiga to Amiga Ethernet Network Arrives* Just hours before this issue went to press, we received a new product from I iydra Systems of England AMIGANET, a high- end, Ethernet networking system for the Amiga. Included with the system was a DMA plug-in board, ThinWire Ethernet™ RG58 thin Ethernet coaxial cabling, and installation software. After muddling through the manual, and a relatively simple and straightforward installation. We were up and running in a few minutes. It's i 1C)T!
NO SERVER REQUIRED AMIGANET is Ethernet Version 2-compatible. And is fully compliant with IEEE 802.3 standard types A and 15. Separate versions are available for the 300 and 2000 series. In addition, Hydra Systems has announced a soon-to-be-released adaptor for use with the A10CJ0. AMIGANET can be implemented with standard Ethernet (Type A) cabling, or the less expensive ThinWire Ethernet™ KG38 ¦‘Cheapernef (Type 15) coaxial cable. AMIGANET is the only Amiga Ethernet network to offer logical connection to shared (remote) hard disks and floppies as well os die serial and parallel ports.
It's jusi like being there. It's a server-less network!
AMIGANET also includes the ability to talk (chat) with other users on the network, and the ability to access remote printers and devices. Another promising feature is a highspeed unidirectional interactive "pipe” mechanism, which passes real-time data at a high rate between AMIGANET nodes.
(Did 1 hear someone say Arexx port?) All of this power can be accessed with icons or through the CLI.
RAW NETWORK HORSEPOWER The best part about AMIGANET is its blazing speed. AMIGANET boasts a 16-bit data path with a 10-megabaud transfer rate using a 16K buffer,This translates into an instantaneous transfer rate of approximately IMB sec. The AMIGANET board is DMA and can directly access Cl III1 and FAST RAM. The DMA sequencer has a 16-.MI5 address range.
Future developments for AMIGANET include support for TCI1 II’ and file servers.
Novell client software is now being written and is slated for a February' ‘90 release. We hope to put AMIGANET through the paces, and give you a full report next month.
The A2000 board retails for S797.00. Pricing for the A500 and A1000 systems will be slightly less.

• SENSOPRO• (FRIED FISH DISK 283) SensoPro is a freeware program
written by Peter Handel from West Germany. This version was
released to Fred Fish for distribution in his collection.
Anyone else interested in distributing this program in their PD
collection must first contact Peter. His address is on die
Intro screen in the game.
OPTIONS SensoPro has many features of a commercial program.
Among diese is a catchy rock and roil song that plays in die background before a game begins. Also, there are professional- looking grapliics, not to mention the nice double-fade from the intro instructions screen to the game screen.
There are several gadgets diat you can seiect. You can turn sound on or off with the Sound gadget. The music only plays at die beginning of the game and in between games.
The Replay gadget will make die computer replay the iast sequence in case you missed it the first time. You can only Replay each sequence one time.
There are diree Level gadgets. Each allows you to select a different level of difficulty for the game you are about to play.
The Start Game and Quit gadgets do just as they imply.
HI-SCORE There is also a hi-score list to record your new scores. This way you can show your friends that you really did make it to 99 iit pads (the maximum number).
SensoPro is another quality PD game. If all of the PD games were gathered together they would make a very nice coilection of free games for the Amiga.
LAYOUT SensoPro is similar to die hand-held electronic Simon game. The game screen consists of a round disc with four light pads on it. Each pad is of a different color and has a different note diat is played when lit. Down the right side and bottom of die screen are several gadgets that allow you to control different aspects of the game.
GAMEPLAY The object of the game is to click on die Nahbing those pads in die same order as the computer. Nasty viruses: Initially the computer will randomly pick one ZeroVirtis 2 01 pad to light. You would then click that same pad. The computer then picks another pad.

• AC- (PD, continued from page 64) 'LINER (FRED FISH DISK 285)
'Liner is a freely redistributable program written by David
Schreiber. David got sick of trying to write an outline in his
word processor, so he wrote ‘Liner. Necessity is the mother of
invention.
WHAT IT DOES ‘Liner allows you to easily create outlines. It will automatically keep track of the numbering and indents. It has all the basic word-processing features. And ‘Liner is straightforward, allowing you to concentrate on your oudine and not how die program works.
FEATURES ‘Liner allows you to load and save your oudines. You can save in either outline format or ASCII. This would allow' for editing in a word processor later (if needed) or for use in a desktop publishing program. Copy, Cut, Paste, and Erase are all available. The Copies and Cub are sent to the Clipboard for use with other programs such as Notepad (comes with all Amigas on the Extras disk).
The ability to switch between interlace and non-interlace is also provided.
This is handy because it allows 48 lines of text to be displayed on the screen at once instead of the normal 24. One reason this is important is because 'Liner can highlight a maximum of one screen.
‘Liner is a straightforward, easy-to- use program that has many features of die commercially available outline programs.
One feature that some commercially available oudiners have that 'Liner doesn’t is the ability to compress areas of the oudine out of sight, making for easier reading on large oudines. It may have enough features for what you are doing.
VIRUS HELPERS VIRUSX 4.0 & ZEROVIRUS 2.01 (FRED FISH DISK 287) VIRUSX 4.0 VirusX 4.0 by Steve Tibbets is an update to version 3.20 The new version checks for more viruses than the old version. Version 4.0 also checks for the Xeno virus that was mentioned in last month’s “Virus Alert” (AC V5.1, page 2).
VirusX runs in the background and checks each disk inserted for known viruses. VirusX 4.0 will also check memory for known viruses when it is first mn.
ZEROVIRUS 2.01 ZeroVirus is another nice virus checking program. This version is freely redistributable and was written by Jonathan Potter. ZeroVirus III is an update to this version and will be a commercial product. It is available from Micro Momentum, Inc. (See this month’s “New Products and Other Neat Stuff’).
ZeroVirus is an integrated virus checker and killer widi bootblock save restore feature. It can find bodi bootblock and file-based viruses.
One feature ZeroVirus has that odier virus checkers do not is the use of brain- files. ZeroVirus uses brainfiles to recognize what is and what isn’t a virus. There are two distinct benefits to this method. One is that, onceanewvirusis fou nd, only die brainfile needs to be updated (as opposed to rewriting the entire program).
The second is diat ZeroVirus can tell if a bootblock is non-standard (as odier virus checkers will), and it can also tell you if the non-standard bootblock is safe. For instance, if you have a disk that has a text- displaying program on die bootblock, ZeroVirus will tell you that it is a text-display program. Other virus checkers will tell you that the bootblock is non-standard, leaving you to believe that it is probably a virus.
The brainfiles that ZeroVirus uses can be edited with an on-line brainfile editor. This means you can make ZeroVirus learn new bootblocks (whedier they are viruses or useful bootblock programs).
ZeroVirus can also be iconified. This means that you can run it from the Workbench and check for viruses, etc. When you are done, ZeroVirus allows you to iconify it.
This causes the w'hole program to change to a small tide bar diat displays the time and memory usage. But the program is still fully functioning in the background. It will continue to check memory and disks inserted for viruses. And if you activate die tide bar and click the right mouse button, the program reopens to a full screen!
Both VirusX 4.0 and ZeroVirus are a requirement for anyone who swaps disks with friends. These programs can save you major headaches down the road.
• AC- mm TELEPHONE Ass&tniiif lan aa f row by Martin F. Combs
AmigaBASIC is relatively speedy for an interpreted language,
but eventually most BASIC programmers develop a yearning for
more speed. This yearning applies particularly to those users
who get their thrills from recreational mathematics problems
such as those found in the Computer Recreations column of
Scientific American. One solution is to go to a compiled BASIC,
and there are some good fast compilers out there. Another
possibility is to learn a new language such as Pascal, Modula
2, or C. The ultimate speed demon of languages is Assembly
language, with some programs running on tire order of 100 times
as fast as BASIC, but only a dedicated programmer would write
stand alone programs in Assembly language. There is, however,
an alternative.
In any program which needs significant speeding up, the portion of the program which uses most of the time is usually found to be a loop of a few lines of relatively simple code, which the computer executes over and over again perhaps thousands of times. Radier than writing an entire program in a new language, write just die loop in Assembly language.
Chapter 8 of die AmigaBASIC Manual describes die keywords available in the BASIC language, including the keyword CAI.L. CALL has three uses, one of which is “calls a machine language routine at a fixed address". The description of CALL goes on to say a number of things which may not be understandable to the average AmigaBASIC programmer. This article provides a number of hints which should at least get the reader started, assuming the reader has a book on programming die 68000 computer and would like to get some hands-on experience. The Motorola 68000 is the guts of the Amiga, as well as of
several odier ¦well known computers. “Programming the 68000" by Steve Williams, printed by SYBEX is a good example. There may be some genius out diere who can learn Assembly language programming by reading a book, but most mere mortals find “learning by doing” much easier.
First look at die BASIC statement “CALL name”. When the CALL statement is executed, the Amiga shoves die contents of die variable “name” into die program counter (PC). Whatever machine language roudne happens to be at the address specified by the PC begins execudon. Therefore “name” must contain an address, which means diat name must be a variable able to carry an address.
Single or double precision floating point will do, as well as die long integer type. A regular integer is not large enough. Call this variable startcode.
The variable startcode must point to the start of the machine language program. Assume that an Assembly language program had been written, having assembled the program into a sequence of byte, (diat is numbers all of which must be in the range from 0 to 255), and those numbers have been converted into a bunch of DATA statements which are part of die BASIC program. That’s one way to do it, but diere are odiers.These numbers dien need to be located where die program can find them. The Amiga has a way of moving stuff around in memory widiout letting die user know, in the sometimes mistaken idea
that it is not impoitant. One way is to Since all variables and arrays have been defined to be of the long integer type, each element of die p() array will contain four DATA items. A machine language program of up to 84 bytes could be held here, since POKEing starts at p(10) and must stop at p(30).
The array can be made much bigger, of course. In the fifth line, 999 is die EOF or end-of-file signal, which will be the last item in the data statements. J=0;k=0 is a statement initializing variables j and k. and is essential even though BASIC would assign a zero value to them when first encountered if diey had not been initialized. If this is not done, die Amiga will make room for them in the variable list when it first encounters diem, probably changing the location of the p( ) array in die process. This would be disastrous, because startcode would then hold the wrong value. The usual
result is anodier one of tiiose frustrating Guru messages as the machine wanders off into never-never land. Now is a good time to mention that if the CALL statement is used frequently, you will be seeing a lot of Gum messages. They cannot inflict permanent damage, but will waste a lot of time. You can always reboot die machine. The reason die POKEing started at p(10) radier than p(0) is because readily available variables p(0) tlirough p(9) can pass parameters to and from the machine language program conveniendy.
Once the statement CALL startcode is executed, the PC is set to the value held in startcode and points to the first item of data.
What should the start of die machine language program do?
Probably the first thing that should be done in the Assembly language program is to protect the informadon in the various data registers. The 68000 computer has S data registers, known as d0 through d7, and 8 address registers known as aO dirough a7.
According to the various Amiga manuals it is safe to use dO, dl, aO and al widiout protecting diem, but why take a chance? Here is a simple Assembly language program: U V mmmm POKE the numbers into a string, but die Amiga does some peculiar diings to strings. It’s preferable to POKE diem into an integer or long integer array. Dimension die array big enough to hold the machine language program and in addition, big enough to hold any information that may get passed to or from the program. Remember that 2 of diose numbers from 0 to 255 will fit into one element of an integer array, or 4 of them
into an element of a long integer array.
Here is a fragment of a BASIC program which will do the job: DEFLNG a-z : DIM p (30) j=0:k=0 starteode=VARPTR(p(10)) again: READ j IF j-959 THEN loaded POKE startcodei-k., j k=k+l : GOTO again loaded: REM BASIC program continues here REM: DATA statements must be somewhere in the program.

The first instruction pushes all registers except a7 onto the stack using the pre-decrement mode. Any good book on the 68000 will clarify terms like "pre-decrement mode". In other words registers are being pushed onto a stack which uses register a7 as the stack pointer (sp). Notice that a7 and sp mean die same thing to tire assembler program. Line 1 is a bit of overkill, since many
oi the registers are not used in the program, but it’s still a good idea to start a program this way. I never know what registers I will be needing until after I have used them, since my programming technique is to lay down some code first and get organized later.
It's not what computer scientists teach as structured programming, but it does make life interesting. Line 10 restores the registers to their original condition before leaving the program.
Line 2 is a bit confusing. Its effect is to load the address which is 46 less than the present value of the program counter into register Circle 113 on Reader Service card.

| Calljwoi OO am £2 t3 ro CD CD cc a5. Six of that 46 comes from the fact that the program counter started at the location of p(10), that is at the start of the program, processed line 1 which is a 4 byte instruction, and then was increased by 2 more in processing line 2. The other 40 come from the distance from p(0) to p(10), with every element of the array taking 4 bytes. Now register a5 points to p(0).
In line 3, the contents of register d7 are moved to (a5), the location pointed to by a5, and a5 points to p(0). Why are the contents of d7 of interest? When calls of the form call startcode(a) or call startcode(a,b) are made, the value of a ends up in d7, which can be convenient. For calls of tire form call startcode(a,b,c,d), check die results and discover die problem. If the call is call startcode(a), then the value of a is also on die stack somewhere, in fact the whole list of variables will be on die stack where they are accessible.
Line 4 moves the contents of the location 60 greater than that pointed to by die stack pointer into 4(a5), which is four greater dian (a5) and therefore must be p(l). Why 60 greater? Since the Assembly language program started to run, 15 registers were pushed onto the stack by line 1. Therefore, 60(a7) must be what die stack pointer was pointing to when the program started, and the contents should be some hint to the computer as to how to get back to BASIC when asked to do so by line 11, the rts or RETURN statement. When die complete BASIC program is eventually run; it is noticeable that p( 1)
holds a large number, presumably an address, but it will only be of an academic interest to die user.
Line 5 moves the contents of 64(a7) into p(2) for future examination. This is the value of variable a, which is the last thing diat gets pushed onto die stack before the call is made. It turns out that if the call statement includes a variable list, the variables get pushed onto the stack in order from right to left. Lines 6, 7 and 8 move the remainder of die variable list into p(3) drrough p(5).
Line 9 illustrates another non-standard but still highly effective way to pass variables to an Assembly language program. In this example, a copy of the contents of p(6) are moved to p(7), but die contents of any of the array elements from p(0) to p(9) could be passed to the Assembly language program to be used as needed.
It may be easier to pass variables in both directions by diis mediod rather than on die stack, since die status of die stack can be rather confusing at times.
Lines 10 and 11 have been discussed but line 12 needs a bit of explanation, which brings up the subject of assemblers. Spending $ 20 or so to buy a book on how to program the 68000 is not a major investment, but it is a bit much to expect casually interested programmers to buy assemblers to find out if they really like programming in Assembly language. The alternative is to obtain a public domain assembler. The a68k program on Fred Fish disk -110 is an outstanding assembler, easy to understand and to use. Its output, a machine language file, can be inputed into a simple program which
manufactures DATA statements. An adequate BASIC program that does this is listed at the end of the article.
(.Although the a68k assembler will get die job done, eventually dedicated Assembly language programmers need to know how to access the built-in routines of the Amiga, i.e. the ‘‘include’’ files will be needed, which means buying an assembler. That is an entirely different subject. Don't worry about it until a much better understanding of die Assembly language is obtained.) Since die a6Sk assembler assumes that the program being convened to machine language will be a stand alone program, it acids some code to assure that tiiis happens, both at the beginning and the end of the program, This
code must be stripped off if the program is to be called from BASIC; this code is easily recognized. The code for line 1 is 72, 231, 255,254 and any code before this should be discarded. Back to line
12. The code for nop (no operation) is 78, 113. Just put line 12.
Or several copies of line 12, at the end of the code and it
will be obvious where the unneeded code at the end starts.
Not all programs end with the rts statement, but the 78, 117
code can Ire recognized as a rts instruction, You will
probably want to make many calls to a machine language
routine, using a loop, which will probably grow out of
necessity. The value of startcode can be reestablished each
time through the loop, but that is a waste of time if it
doesn't change, and if careful, it won't. The trick is to
initialize every variable (string or numerical) that is being
used in the loop before establishing the value of startcode.
Initializing means setting the variables to something even if
the value will be changed later. If using a string known as
aS then put the assignment statement aS="” before the
startcode=VARPTR(P(10)) statement. Repeated encounters with
the Guru, might be solved by putting the startcode statement
in the loop. If this works the source of the problem has been
narrowed down.
The terms Assembly language and Machine language are often used somewhat interchangeably. Assembly language is a relatively easily understood language which is written on a text editor such as the ED program provided by Commodore. There are many more efficient text editors available commercially or through the public domain. My favorite is dme by Matt Dillon. (If you are interested in public domain software, do yourself a favor and check into dme, dmouse and shell, all by Matt Dillon.) The assembler processes this ASCII file, creating a file which is the machine language program. Typically one

' movem.1 (sp)+,d0-d7 a0-a6 ' rts ' end For the unbeliever, Assembly language programs definitely do run faster than BASIC programs, many times as faster. They also seem to take one hundred times longer to write than BASIC programs, mostly because they are much harder to de-bug. So why not have the best of both worlds by combining the two. Write most of the program in BASIC and just the highly repetitive stuff in Assembly language. The results wall be amazing.

(Schmideo, continuedfrom page 47) area = better fidelity, decided to put the audio record and playback heads on the same rotating drum as the video heads.
Now we have the same incredible tape-to- head speed ratio with our audio as we do with our video. A great idea hut where on die tape do we store the sound? We could not use die same narrow track as the mono Dolby stereo sound or we would lose compatibility with all previous and current machines.
Remember, I did say that this engineer was very clever. The idea that was finally decided upon is the method that is currently in use. The two audio tracks are encoded (multiplexed) into the video signal and actually stored on the full width of die tape at die opposite angle to the video signal and on a deeper layer of magnetic particles. Voila! Faster speed and larger recording area. Perfect? Maybe not.
Since this is a totally different record and playback system from die mono Dolby stereo systems on previous machines, a tape recorded on a Dolby stereo machine, for example, would have no Hi-Fi tracks, and, therefore, no sound would be heard when played on a Hi-Fi machine. The reverse is also true. A tape recorded with only Hi-Fi sound would have no soundtrack playable by a machine with mono or Dolby stereo heads. In order to solve this final problem of compatibility, all Hi-Fi machines are also equipped with Dolby stereo record and playback heads.
Therefore, when you play a tape you can listen to the mono or Dolby soundtrack, if that is all the tape has, or you can listen to the Hi-Fi soundtrack, if there is one. For backwards compatibility, when you record on a Hi-Fi VCR, you are actually recording two soundtracks at once. You see? This way you can listen to die Hi-Fi track when you play it back, but your stingy neighbor with the ten-year-old VCR will still be able to listen to the soundtrack as well (if you loan him the tape).
The average Hi-Fi VCR lias a record and playback range of approximately 20 to 20,000 Hz (using die Hi-Fi tracks). That's right! The full range of human hearing. In fact, it is only the signal-to-noise ratio and die resulting dynamic range that set this level of sound quality apart from that of compact discs. And the difference is actually reladveiy small. (Note: serious audiophiles were making copies of their favorite albums on Hi-Fi VCR’s years before CD's became popular.)
THE NAKED TRUTH So, back to why I brought this all up.
Any of you readers who are into Amiga video eidier have or will need a VCR and or camcorder. Both VCR’s and camcorders are available with three levels of sound recording and playback quality. Most of die low end home VCR's and the majority of all camcorders in existence use mono sound only. An increasing number of units are now available with Dolby stereo (sometimes known simply as stereo). All of the top end VCR's and camcorders offer Hi- Fi sound. Now we are getting to diat pet peeve.
An ever-increasing number of VCR’s and particularly, camcorders, are available with a feature called audio dub or dubbing or even over-dubbing. This is particularly true of the better models. Audio dubbing is the ability to record or rerecord a soundtrack on videotape independendy of die video signal. For example, you tape your family at die beach and when you go home you would like to "dub" a narrative track onto your tape. To do this without disturbing the already-recorded picture, you will have to have a machine with the audio dub feature.
The more clever among you will ask,"if the Hi-Fi track is mixed in with the video signal, how can I rerecord it widiout changing the video portion of my tape?” The answer? You can’t! This is the crux of my peeve. I constantly see references to VCR's and camcorders with "Hi-Fi sound and Audio Dubbing". Apparently I am not die only one who finds this misleading. A good friend of mine, having recently bought a camcorder with Hi-Fi sound and...you guessed it, audio dubbing, asked me why the quality of die sound recorded with the picture was so good, and yet, when he dubbed over the sound, no
matter what he did, die quality just wasn’t the same.
DONTBE FOOLED In my friend’s case, it not only said "Hi-Fi Sound with Audio Dub” both on the box and in the manual, the salesman had specifically pitched him on the Hi-Fi quality of die overdubbed sound.
Does this mean that you should avoid atidio dub like die plague? Absolutely not.
It is an extremely useful feature which can, at times, become invaluable. It can really be very hard to live without. Just remember, when you are dubbing sound using diis feature, you are dubbing onto the Dolby stereo tracks. This means you arc back to diat 100-10,000 Hz sound quality. So plan accordingly.
If you will be using semi-professional editing equipment (most of which will allow simultaneous playing of the Dolby Stereo [or, linear tracks] and the Hi-Fi tracks) just remember to put the voice on die linear track and the music or sound effects on the Hi-Fi tracks.
Also remember that w'hen you narrate over that trip to die beach you probably will not be able to listen to die sea gulls at the same dme you are listening to die narration. Again, diis is because most consumer equipment will not allow' playing of both types of soundtrack at once. There is a bit of a workaround to this in that with some VCR’s and camcorders die audio dub feature will allow you to independently rerecord the right and left linear tracks. Remember, wdiile you originally recorded those sea gulls on die Hi-Fi tracks of your camcorder, you also recorded them on die left and right
Dolby stereo tracks. Therefore, if your machine will allow you to overdub, say, die right linear track without disturbing die left, then you can play those linear tracks as your finished product, listening to the narration and the sea gulls at the same time.
Hopefully, diis information will help keep you from being flimflammed by eidier overzealous boxes or overexuberant salespeople. And please, if any of you go on to write books about Desktop Video, do not mention I li-Fi and audio overdub in the same sentence without explaining that they are not related!

LEVEL DEBUGGER For those of you who may not know, a source
level debugger is a tool which allows you to troubleshoot a
developing program. It lets the programmer single-step through
program statements, examing and modifying variables, A source
level debugger differs from a symbolic debugger in diat
while die symbolic debugger operates at die assembly language
level, a source level debugger works at the original
high-level language mode. Thus, a source level debugger is
much more conducive to high- level language thinking, widiout
having to get bogged down by compiler-generated assembly code.
THE PACKAGE The Benchmark SLD package consists of a manual and one disk. The disk contains a few files, most important of which is the debugger, a new version of die compiler, and a module called PMD (both ,SBM and .OBM files are supplied, naturally). The new compiler version is IdenU- cat to the previous one, except that there is some additional debugger support. The PMD module is used if post-mortem debugging is desirable. Also included on the disk is a program called WBColors, which toggles the number of bitplanes in die Workbench screen between 1 and 2. Running with only one
bitplane saves about 16K of CHIP RAM, so this is quite useful for owners of 512K system. Another included utility, M2Detab, is used to filter out tabs in source files. More about this tool later.
Over a year ago I had a conversation with Leon Frenkel of Avant-Garde Software, trying to convince him of the importance of a source level debugger for his Benchmark Modula-2 compiler. He was not impressed at the time, claiming that the usefulness of a debugger would be limited.
Well, I’m glad Leon has changed his mind, and now he has produced one of die best debugger packages I’ve seen anywhere.
Top: Module List window displays all known modules.
Bottom: 71 je Option menu allows you to select options for the debugging process.
INSTALLATION Installation is very simple. Simply copy the new compiler to where die old compiler was. Place the debugger into the same directoiy as Lhe compiler, and copy PMD.OBM and PMD.SBM to the directory where you keep all die odier support modules. You might also want to place one of the supplied configuration files in the S; directory under the name M2Debug.Config. The debugger will read this file upon startup, and set itself up accordingly.

The linker must generate source level debug inl'o. This can be specified by using die -g’ option for a Clt-based link operation, or by issuing the command ‘M-x set-m2-link-gen-sym’ in die editor, specifying ‘TRUE’ for the
source level debug info prompt. An easier way is to place die following command in die Si.emacs file: (set-m2-link-gen-sym T F F) In addition to die linking instructions, all modules which have to be debugged must be compiled widi the refer- ence-fiie option turned on. Again, this option can be invoked by using the ’-g' argument for a CLI-base compile, or by using the ‘M-x set-m2-comp-opt' command in die editor. In addition, this can be set via the M2Config utility.
Once the program is compiled and linked properly, it can be debugged by issuing the following command from the CLI: [run] m2debug ProgramName Com- mandLineArguments FENESTRATION (OPERATION WITH WINDOWS) The Benchmark SLD is fully “intui- tionalized”. All commands are invoked through mouse clicks and menu selections.
In addition, the function keys are used for activating certain menu selections. The SLD is quite similar to the MetaScope symbolic debugger in this aspect. Just as with .MetaScope, numerous types of windows may be opened, and the number of open windows is limited only by the availability of CHIP RAM (see Picture One, for an example debugging session with many kinds of windows open). In addition to horizontal and vertical slider gadgets, each window also has an additional “destination” gadget, which is used for various kinds of navigation.
The SLD's pow'er and flexibility stem from its window capability'. The following window types are available: Source window - displays the Modula-2 source code.
The next statement to be executed is highlighted in inverse video. A breakpoint can be placed at a source statement by simply double clicking on it. That statement will then appear in a different color, to denote it as a breakpoint.
• Symbolic data window - displays the variables’ content. It's
possible to display module global variables, as well as proce
dure local data. For variables of simple type, their type and
actual value is displayed in die appropriate format. For
variables of a more complex structure (array or record), only
their size and type is displayed. To display a complex
variable’s content, simply double-click on it. If die variable
is an array, die window will then display the individual
elements. Similarly, if die variable is a record, the window'
then will display die individual fields.
Circle 129 or Reader Service card.
For pointer variables, the window shows their address value. Double clicking on them causes the wfindow' to display the object pointed to (assuming the pointer is not NIL). Set variables (of type SET OF ...) are displayed as a hex number, which is really dieir bit pattern. Double-clicking on them causes the window' to show' the names of all possible set members. The members diat are actually contained in the set are highlighted.
Pressing BackSpace , or doubleclicking the top line of the w'indow’’s display, will return the window to its previous state. Pressing Escape will restore the w'indow to its initial state (showing the top level list of variables).

Variables may be modified by selecting them and then pressing F9. A requester will be displayed, showing the variable’s current value and prompting for die new value.
• Disassembly window - displays die assembly listing of the
source code. This is quite handy, as sometimes it’s quite
important to know what exacdy is taking place.
The next assembly instruction to be executed is highlighted in inverse video. As widi the source window, breakpoints can be set in this window (by double-clicking on an assembly instruction), and they will appear in a different color.
• Procedure call chain window-displays a list of currendy active
procedures, with the most current active procedure on top. This
shows you exacdy how the program got to where it's currently
at. This is also useful for navigation: selecting a procedure
in this window (simply click on it), and then clicking on a
source window’s destination gadget will cause die source window
to display the procedure’s code. Similarly, clicking on a data
window's destination gadget while a procedure is selected will
cause die data window to display that procedure's local data.
• Memory window - allows you to display memoiy in all sorts of
ways (as individual bytes, characters, strings, binary
integers, reals, etc.).
• Registers window - displays all the CPU's registers. All
registers may be modified by selecting them and pressing F9. A
requester will appear, prompting fora new value. Of course, if
you are about to change some register's value, you’d better
know what you're doing.
¦ Module list window - displays a list of all known modules. For each module, the window displays whether it “knows" about the corresponding .mod, .def, and .rfm files. This window is useful for navigation: select the .mod or .def entry for a module, and tiien click on a source window’s destination gadget to display the corresponding code. Similarly, select the .rfm entry for a module and click on a data window’s destination gadget to display the variables declared in that module’s .def file (this is a bit obscure, but it works).
• Info window - displays various useful things about the system,
such as open libraries, devices, ports, etc.
• Directory window - displays directories and their files. I
found this one pretty useless.
PROGRtUM CONTROL A debugger must have ways of controlling the program being debugged. The SLD has two types of 'Step1 and ‘Run’ commands. The ‘step into’ command will execute one Modula-2 source statement and tiien stop. If the statement happens to be a procedure call, the debugger will step into the procedure and stop. The 'step over’ command is similar, except that a procedure call is executed without stopping.
Execution will stop as soon as control from the procedure. The ’Run’ commands are similar to die ‘step’ commands, except that the debugger will keep executing source statements until the 'stop' command is issued. As with ‘step’, there is a 'run into' and a ‘run over’ command. Single stepping can be at die Modula-2 level, or assembly level, depending on a menu selection.
In addition to ‘step’ and ‘run’, diere are two kinds of 'go’ commands. The regular go command will let die program run unchecked. Control will return to the debugger only after the program terminates (by either executing a HALT, or by simply exiting), or when it encounters a runtime error or a breakpoint. The ‘go with temporary breakpoint' command will place a temporary breakpoint at the selected source statement, and then issue a ‘go’. The temporary breakpoint will be cancelled as soon as the program encounters it. At that point, control will return to die debugger.
As mentioned earlier, setting breakpoints is as easy as double-clicking on a Modula-2 source statement, or an assembly instruction. While all other source level debuggers I’m familiar with allow setting a breakpoint on a particular line, Benchmark's SLD goes one step beyond; it allows breakpoints on source statement. That means, it can handle multiple statements on one line.
HANDLING OF CPU EXCEPTIONS (RUNTIME ERRORS) The debugger should trap and handle any runtime error which results in a CPU exception. Such runtime errors include dividing by zero, array subscript out of bounds, and overflow (for example i := b - 4, where i is INTEGER, and b is a CARDINAL set to 3). I found the SLD a bit lacking in this area.
Single stepping into a statement which causes an exception (such as the CHK or Div by Zero) will cause the Amiga to crash. This is actually not Benchmark's fault; it will happen with all debuggers since tire problem is with die Amiga DOS.
This is briefly mentioned in the manual (page 4-12) in one short sentence, so it’s quite easy to miss.
If division by zero of REAL numbers is encountered during a “go”, the debugger will not single step after the exception.
Instead, it will perform a “go” even though tire user selects “step".
The debugger does not make a distinction between an array subscript, out of bounds error, and an overflow error. This is actually due to a “feature” of the compiler, and is not tire debugger’s fault; tire compiler generates code that signals a CHK exception for both types of errors.
POST-MORTEM AND WORKBENCH APPLICA TIONBEGUGGING The package comes widi a new module which you should import into all your programs. The new module, PMD, will invoke the debugger in the event that a program encountered a runtime error.
The debugger will load in the program’s source and display tire offending line and type of exception. Unfortunately, there is a bug which shows up if you try to single step past tire end of the program (this is probably related to one of the problems mentioned above). Otherwise, the PMD SLD combo works as advertised.
While the SLD can be run only from tire CLI, there is a way to use tire debugger with Workbench based programs. The trick is to import PMD and code an inline instruction at tire beginning of the program to signal a trap. Once the program is launched from the Workbench, it will encounter the trap and invoke the debugger.

There are options for searching through memory or through source, including copying and filling memory blocks.
The Benchmark debugger is remarkably reconfigurable. At any given moment the user can save the debugger’s current configuration to be used later.
Items that can be customized include: screen and window colors, workbench vs. custom screen, interlaced vs. noninterlaced, how many and what kind of windows should be initially opened, etc.. There is an option to enforce version control, called '‘Verify .MOD File Dales".
Enabling it means that the debugger will insist that the program being debugged was linked from object files (.OBMs) that are completely up-to-date. If you choose to use this option (as it provides more security), beware of the following pitfall. If you edit a source file, be sure to compile and link from within the editor, and then debug the resulting program, without first saving the editor’s bufferto disk, tire debugger will complain with tire message “An ‘.REM’ and ’ or ‘.MOD’ file was not found for die program module”.

DOCUMENTATION There is not much to say about the manual. It is in the same fonnat as all the other Benchmark manuals. While it has all the needed information, it’s not organized very7 well, and there is no index. Basically, tire only thing you can do to assure full knowledge of all the debugger’s features, is to read the manual completely, thoroughly, and sequentially, since looking things up isn’t easy.

Handle tabs at all. Tabs appear as a strange rectangular characters embedded in the source, and all the gorgeous indentation that you have painstakingly put into your program is completely missing. This is inexcusable, especially since the integrated editor inserts tabs, and has no option for “soft tabs” (inserting spaces when the TAB key is pressed). The debugger does come with a utility called M2Detab, which will filter out die tabs. RM2Detab should be used on a module BEFORE the module is compiled.
The debugger's file requesters are lousy!
All you get is a simple string requester. In this day and age of ARP and other similar freely available file requesters (not to mention the one available in the editor!), not having a smart file requester is unacceptable. It IS possible to use tire directory window to "sort of’ function in conjunction with the file requester: select the desired file in the directory window, and then issue die command which puts up the requester.
The selected file will appear in die requester. I dislike diis feature, since it’s inconsistent with the Amiga de facto file requester standard.
Variables are displayed in die data windows in their order of declaration. There is no option to list them in sorted order. This becomes a major pain in die neck when diere are lots of variables, and you have to scroll up and down die variable list in order to find a particular one. It could be argued that the order of displayed variables is a matter of preference, but it woidd have been nice to at least have an option to choose die order of display.
There are no condidonal breakpoints or watchpoints, A wacchpoint is a breakpoint on a variable, which gets invoked when the variable is modified. This can be useful for tracking bugs that mysteriously zap some memory. I understand that diis feature cannot be implemented efficiendy on the Amiga (for lack of hardware memory protection), but I'd rather have an inefficient implementadon than have nothing at all. A conditional breakpoint is one that gets invoked if a certain condition exists. The SLD has a "counted” breakpoint, which will be activated after it has been encountered a set number
of times, but it is no substitute for a true conditional breakpoint.
There is no graceful way to exit early and clean up. If die program being debugged allocates resources (memory, screens, etc.), those resources will not be freed up if the program is tenninated prematurely.
Granted, the debugger should not have to keep track of resources allocated by the user, but there should be some mechanism for releasing it (e.g. a facility to call some termination procedures. Leon actually has something like that, but it’s not widely available. You can always ask him for it).
The destination gadget doesn't apply to all types of windows, but it’s present in all of diem. This just adds confusion.
Some things aren’t obvious; for example, how do you display variables declared in a definition module? (the answer: select the corresponding .RFM file in the Module List window, and then dick on the destination gadget of a data window). The command to change variables and registers (function key F9) does not appear on any menu. The only wray to find out about it is by reading die manual.
SUMMARY Despite the minor problems, the Benchmark Source Level Debugger is an excellent product. Overall performance is good and the user interface is quite slick. It is obvious that a great deal of time wrent into developing it. If you are serious about programming in Benchmark Modula-2, then I suggest you purchase the debugger; it is worth the investment.

decided to write one function capable of generating evert'
requester I needed. To accomplish this task, I used dynamic
memory allocation, DYNAMIC MEMORY ALLOCATION ON THE AMIGA
After studying the various methods of allocating memory on
the Amiga, I decided that using the AllocRemember function
provided by the Intuition library would be the simplest
mediod.
This function creates a linked list of memory blocks using a Remember structure (defined in intuition.h). A Remember structure has the following form: struct Remember ( struct Remember ‘NextRemember; U10NG RememberSize; U3YTE *Kemory; I This structure contains a pointer to another Remember structure an unsigned long integer containing the size of the memory block, and a pointer to the memory’ block allocated. The Nex- tRemember pointer makes the linked list of memory blocks possible.
In order to create a linked list, a pointer to a Remember structure must be declared and initialized to NULL as follows: struct Remember 'MyMemBlocks = NULL; Suppose that two blocks of memory, one 100 bytes long and the other 200 bytes long, are needed by the program. The AllocRemember function is called as follows: ir.ein_pointerl = AllocRemember (SMyMemBlocks, 100,MEMF_CLEAR}; The first argument is the address of the Remember structure pointer. It is important to remember drat this is not a pointer to a Remember structure, but a pointer to that structure pointer. This is illustrated in
Figure I. The second argument is the amount of memory to allocate (in this case 100 bytes). The third argument contains flags (defined in memory.h). MEMF_CLEAR fills the memory' block with zeroes after allocation. Other flags include: MEMF_FA3T Allocate fast (external) memory MEMF_CHIP Allocate chip (internal 512K) memory MEMF_?U3LIC Allocate memory for different tasks or r-.terrupt code such as task control blocks, messages, etc. FIGURE 1 Address of a Pointer CO a Remember Structure &MyMemBlocks - My.MemB locks Pointer V h Remember Structure If none of the above flags is set, then MEMF_FAST
is assumed first.
If no fast memory is available, chip memory is used.
If the AllocRemember function is successful, it returns a pointer to the allocated block of memory. If it fails, it returns NULL.
AllocRemember actually perfonns two memory allocations: one for the Remember structure and another for the memory block requested, ft also fills in the Remember structure and sets the variable MyMemBlocks to point to the structure. This is represented graphically in Figures 2a and 2b.
In order to allocate the 200-byte block of memory, the .AllocRemember function is called again in a similar fashion as before: mem_pointer2 - AllocRemember (SMyXemBIocks, 200,MEMF_CLEAR) ; Here the function creates another Remember structure and sets the NextRemember element of the previous Remember structure to point to this new structure. It then allocates a 200-byte block of memory (see Figure 2c).
Because of the manner in which die AllocRemember function is called, it is very easy to allocate multiple blocks of memory Figure 2 Graphical Representation of Pointers Before and After Calls to AllocRemember Function &MyMemBlocks - MyMemBlocks
(a) Before call: NULL
(b) After first call: &MyMemBlocks ¦ MyMemBlocks | Pointer |-|
Remember structure NULL 100 byte 10(1 Memory Pointer Block
(c) After second &MyMemBlocks call: MyMemBlocks £ Pointer
NextRemember r 100 byte Memory Remember structure 100 Pointer
Block NULL rf 200 byte Remember structure 200 Memory Pointer
Block of equal size. For instance, to create ten blocks of
memory whicli will each contain an IntuiText structure, the
method shown in Listing One can be used.
After this code is executed, IntuiTextBlocks will point to die first of ten Remember structures that are linked together dirough die NextRemember pointers. Each memory block can be accessed through the Memory element of its corresponding Remember structure. These pointers can be cast to type "pointer to an IntuiText structure” and dien die memory'blocks can be filled in with data as shown in Listing Two.
When the memory blocks are no longer needed, the Free-Remember function can be called, FreeRemember(&Intu IT extBlocks, TRUE); This function will deallocate all the memory blocks in the list, as well as the memory used by the Remember structures. If the second argument is FALSE, all the Remember structures will be erased, but the memory blocks will remain intact.
The mediod just described was used to allocate memory' dynAMIGAlly for various structures and buffers in a function which can create a requester that contains a variable number of string gadgets. This function is entitled StringsRequest and is part of the program entitled StrReq.c shown in Listing Three.
THE STRINGSREQUEST FUNCTION Six separate linked lists of memory blocks are used in the StringsRequest function. Four of these linked lists contain NurnEn- trys Remember structures, where NumEntrys is the number of string gadgets required in the requester. These Remember structures point to memory blocks containing all the Gadget structures and their associated IntuiText and Stringlnfo structures, as well as to buffer memory for the gadget strings. The fifth and sixth linked lists actually contain only' one Remember structure each. One points to a memory block containing a Requester
structure, while the other points to an undo buffer.
The IntuiText structures supply information about text related to each gadget. This text will appear to the left of each string gadget and can be used to identify the type of information the user should supply in the gadget. The Stringlnfo structures supply information about the strings that actually appear in the gadgets. One piece of information in this structure is a pointer to a buffer -where the actual text is stored. There is a separate buffer for each gadget. The structure also contains a pointer to an undo buffer. This buffer is filled in with a copy of a string gadget buffer
when die gadget is first selected. After changes are made to the string in the gadget, the user can revert back to the original contents of the gadget by pressing [Right Amiga)-
Q. One undo buffer is sufficient for all die gadgets because only
one gadget can be active at a time. The Requester structure
des all of the above information together.

NumEntrys The number of string gadgets to appear in the requester.
BoxWidth An array of short integers containing the width, in characters, of the boxes to contain the strings in the gadgets. This array must have at least NumEntrys elements.
Titles An array of pointers to null-terminated strings containing the text to appear to the left of ecch string gcdget. This text will help Identify the type of information each string gadget contains.
This array must have at least NumEntrys elements.
DefText An array of pointers to null-terminated strings containing the initial text to appear inside each string gadget. Make sure the buffers containing the strings are long enough to contain their respective maximum string lengths. This array must have at least NumEntrys elements.
MaxLenDefText An array of short integers containing the maximum length of the strings in each string gadget. This length includes the null- terminator. This array must have at least NumEntrys elements.
TypeDefText An array of short Integers containing either a zero cr LONGiNT (defined in intuition.h). A zero indicates that the corresponding gadget is a standard string gadget, LONGINT indicates the gadget should only accept long integers. This array must have at least NumEntrys elements Window Pointer to the Window structure of the window in which the requester will appear.
Redirected to this file. TestSRwill read die informadon, open a window, and display die requester. After changes are made and either the OK or CANCEL gadget is chosen, the window will close, and the current text from each gadget will be displayed.
HOWTO USE THE STRINGSREQUEST FUNCTION The StringsRequest function is of type BOOL, If the requester is opened and closed successfully, it will return TRUE. Otherwise it will return FALSE. The eight parameters passed to the function are described in Table I, Intuition will not allow a string gadget to be wider than the maximum length of the string it contains. Therefore, if an element of the Max- LenDefText array is smaller than the cone- sponding element in the BoxWidth array, the gadget width will be equal to MaxLenDefText, rather than BoxWidth. The StringsRequest function takes this into
account when determining the size of the requester.
If an element of the TypeDefText array is equal to LONGEST!, Intuition will only allow long integers to be entered into the string gadget, This is useful if the information needed is a number. The initial value in the corresponding DefText array element must still be a string; therefore, it is necessary’ to convert the long integer to an ASCII string before calling StringsRequest. Once the function returns control to the calling routine, the ASCII string must be converted back to an integer, The StringsRequest function uses the information supplied by its parameters to determine the
necessary’ width and height of the requester, so it can contain the string gadgets and associated text. It first allocates the necessary amount of memory, fills in this memory' with ail the necessary clata structures, and then displays the requester. Figure 3 shows a sample requester con- mining five string gadgets. Because the gadgets are displayed in column format, the requester is limited to 10 string gadgets in the requester on a full screen window in non-interlaced mode or 20 gadgets in interlaced mode.
The requester also contains two boolean gadgets, one displaying OK and the other displaying CANCEL. After changes are made to the text in the string gadgets, the OK gadget can be selected to assign the new entries to the strings pointed to by7 the DefText array. If CANCEL is selected, the text that was originally in die gadgets when die requester was displayed remains intact.
After choosing OK or CANCEL, the requester will disappear, die memory allocated to the various data structures will be returned to the free memory pool, and control will be returned to die calling program.
The short program entidedTestSR shown in Listing Four can be compiled and linked to StrReq.c. It demonstrates how the StringsRequest function works. The program prompts the user for informadon about the string gadgets to be displayed in the requester. .Alternately, a text file containing all of this information can be created and the program can be executed widi the input

farmers. While at the camp, the requirement was raised to one
year. After her obligatory year at the camp, at the age of 19,
she entered a pharmaceutical college. Two and a half years
later, she graduated from the college and was immediately sent
to a military hospital to assist die war-wounded. After a short
time at the hospital, she was transferred once more. This time
Lilo was stationed in an airplane parts factory. She spent the
remainder of the war producing airplane parts in a prime target
for Allied bombers.
Later, her husband Klaus returned from his internment in a concentration camp. He was one of six survivors out of 35 men who were in his high school class. .And although Klaus had survived, his return to the couple’s hometown of Gera placed him within East German borders. In 1953, Lilo and Klaus escaped to the West and, in 1954, they arrived in the United States.

AMIGA The AmigaBASIC program, CONUNDRUM, is a puzzle-like game.
The puzzle consists of nine squares, arranged in a three-by-
three matrix, like a Tic-Tac-Toe board. Each square is randomly
colored, either red or green. You solve the puzzle by switching
the colors of the squares, so that the eight outer squares are
all green, and the square in the center of die board is red. To
switch a square from red to green (or vice-versa), simply move
the mouse pointer onto the square, and click the left mouse
button. East'? You bet!
Oops! There's [ust one small complication. Each time you click on a square, not only does that square switch colors, so do some of its neighbors. The squares in the actual game are not numbered, but I will use the numbered diagram, to explain how it works. If you dick on a corner square, that square, plus the three closest squares, switch color. For instance, if you click on die square numbered 3 in the diagram, squares 2, 3, 5 and 6 will each switch color. Click on the middle square on any edge to switdi all three squares on diat edge. Forexample, ifyou click on square 6, you will switch
squares 3,6 and 9. Click on the center square (square 5) to switch die five squares that form a cross (squares 2,4, 5,6 and 8).
Simply continue clicking on squares, as fast as you can decide which square to click on next, until die square numbered 5 in die diagram is red, and the other eight are all green.
1 2 3 4 5 6 7 8 9 At this point, a requester appears, and a computer voice congratulates you. The program pauses undl you dick die left mouse button, as die requester asks, and it then proceeds to set up the next game. The pause gives you a chance to read the elapsed time for your game, and the number of moves that you made. This information is continually updated on a scoreboard displayed just left of the gameboard. Below the scoreboard are two buttons, labelled NEXT GAME and QUIT, which do just what they say when they are clicked on.
By David Senger You will find CONUNDRUM easy or difficult, depending on your ability to visualize special relationships. If you find it difficult, take heart. It gets easier with practice. Also, it is possible to cheat!
Some of the random patterns that the computer generates are much easier to solve than others. In fact, you will occasionally get a game diat allows you to win in just one move, provided tiiat you spot your opportunity.
If you don't like the board layout diat the computer has provided, you can ‘'cheat" by clicking on. Die NEXT GAME button, which will immediately produce a new pattern of colored squares.
Ifyou do not like diat one, simply continue clicking on die button until you get a pattern you like. When you have had enough, click on the QUIT button, and the program will clean up after itself and go away.
To use this program, type in the listing, save it to a disk containing a copy of AmigaBASIC, and double-click on die program icon. Make sure you have Preferences set to eighty columns before you run the program or it won't work properly.
Two or three points about the source code are worth a look.
The program begins by presenting you with a screenful of instructions. When you finish reading and click the mouse to continue, the program blanks die screen to a light blue, simply by setting all four of die PALETTEs it uses to the same color. This conceals the activity on the screen for die two or three seconds it takes die Amiga to draw' and GET the graphic arrays, drawr the game display, and initialize the first game. At this point, the PALETTEs are reset to die colors used during play, and the game flashes onto the screen. This is done by the subroudne ‘ReColor’, and it is here that you
must look for the PALETTE values used during play, and not in the PALETTE statements diat appear near the start of the listing.
If you check the section in which die program draws and GETS die graphic arrays, you will notice that the array ‘Square’ is drawn using PALETTE 1, which is set to black by ‘ReColor’. This may be a little confusing, since ‘Square’ is used to PUT a random arrangement of red squares on the gameboard at the start of each game. The reason that the black array produces a red square is that ‘Square’ is not PUT on the background color held in PALETTE 0 (in diis case, blue), but on the green gameboard, whose color value is held in PALETTE 2. The XOR PUT function (the default PUT function) doesn't
recognize the actual colors held by the PALETTEs, but only the PALETTE numbers. When an array whose color value is held in PALETTE 1 (in diis case, black) is XOR PUT on an area of die screen whose color value is held in PALETTE 2 (in this case, green), it produces tire color whose value is held in PALETTE 3 (in this case, red). Similarly, the graphic array, 'Quit’, is drawn with PALETTE 2 (green), and 'NextGame' is drawn with PALETTE 3 (red). But when they are repeatedly XOR PUT on their PALETTE 1 (black) background by die subprogram 'Flash', 'Quit' displays a red button, and ‘NextGame’
displays a green one.
I’ve used the default XOR PUT function because, in spite of this minor complication, it is so extremely handy. When ‘Square’ is PUT on tire green gameboard, it produces a red square. When 'Square' is PUT on the red square, the green gameboard reappears. This simplifies and speeds up the subroutines (One, Two, Three, etc.) used to draw squares on the gameboard and keep track of their colors, and also simplifies the subprogram, ‘Flash’, A couple of simple routines that you might find useful in your own programs are the subprogram ‘Flash’, and the subroutine, 'Game- Clock’. 'Flash' can be
used to repeatedly draw and erase an image on die screen. It uses two SHARED variables, 'FlashNunT and ‘FlashDe- lay'. The first controls the number of times the image flashes on the screen. Increasing die value of the second makes the routine flash slower.
GameClock' can be used as a general-purpose timer. It is powered by die AmigaBASIC 'ON TIMER(n) GOSUB label' command.
‘SwitdiColors’ quickly calculates which of the squares the mouse has been clicked on, if the mouse pointer is anywhere on the gameboard.
This one-line routine, which replaced about two-thirds of a page of code, shows how fast and convenient integer division can be. The congratulatory spoken messages are held in the array Talk?’, which is defined at the start of the listing.
If you would prefer to hear other comments, they are easily changed.
If you like, you can even change the rules of the game. Take a look at the beginning of the 'subroudnes and subprogram’ section. The first nine subroutines, labelled ‘One’, Two’, etc., define which squares will switch colors in response to a click on any square. They are very straightforward, and easy to understand.
For instance, in subroudne ‘One1, the instruction 'PUTCSXl,SY1),Square’, XORPUTs the graphic array 'Square’ on the gameboard at the position labelled T in die diagram, reversing its color from green to red, or from red to green, as the case may be.
The accompanying instruction, 'C(l)=3-C(l)', switches the color flag variable from zero to one, or from one to zero, which keeps track of the color of square 1 (zero stands for green, and one stands forred). This allows the routine, ‘WinCheck1, to determine whether or not die latest move has won the game, by checking the values of all nine of the color flags.
With a litde tinkering, you can modify these subroutines so that any combination of squares you choose will switch colors in response to a dick on a particular square. You can also change the rules by modifying the ‘WinCheck’ routine. As written, ’WinCheck’ recognizes a win when it finds that square 5, the square in the center of the gameboard, is red, and the odier eight squares are all green.
But you can have 'WinCheck' recognize a win for any combination of red and green squares you choose, just set the color flag to one for each of die red squares in your winning pattern, and set die flag to zero for each of the green squares. If you make this adjustment, you must also set the color flags in the corresponding code near the end of die routine TnitGameBoard' to the same values.
If you revise either the nine subroudnes mentioned above, or the ‘WinCheck’ routine, you might also want to update the instructions diat appear when you start die game, by rewriting die PRINT statements. Experiment with either, or both, of these modifications. You can make the game as easy, or as difficult, as you like.
Thanks to the great speed with which the Amiga draw's graphic images, and thanks to the natural agility of the mouse, I find the game very quick and responsive. It has the quality of transparency, which means that you soon lose awareness of the computer and focus completely on the game. I hope you enjoy it.
I first saw a version of this game in an article and program written for the Cotnmodore 64 in the March, 1987 issue of Commodore Magazine. A tip of die hat to Sally and Richard Daley.
For the AmigaBASIC program that follows, I must take all the blame myself.

The AMICUS & Fred Fish Public Domain Software Library This software is collected from user groups and electronic bulletin boards around the nation. Each Amicus disk is nearly full, and is fully accessible from the Workbench. If source code is provided for any program, then the executable version is also present. This means that you don't need the C compiler to run these programs. An exception is granted for those programs only of use to people who own a C compiler.
The Fred Fish disk are collected by Mr. Fred Fish, a good and active friend of the Amiga.
Note: Each description line below may include something like ’S-O-E-D', which stands for 'source, object file, executable and documentation’. Any combination of these letters indicates what forms of the program are present. Basic programs are presented entirely in source code format.

Lilo and Klaus have retired in Southern California. Lilo spends her retirement learning and playing with the Amiga. For the holidays, she gave her grandchildren a used Amiga 500 purchased with the money she made selling her Commodore 64 equipment. Lilo has become an active Amiga user through her desktop publishing and video work. She enjoys her Amiga and has a large group of fellow Amiga users as friends. With her Amiga, she has been able to remain in touch with her friends and home country.
Lilo Blumenfeld demonstrates why desktop publishing is such an important tool for all of us. It is not always necessary to produce magazines or newsletters for the masses; sometimes it is good to be able to keep in touch with the people that have grown to mean so much to you.
Networking is a fantastic thing, whether it be on die Amiga or with your friends. The ability to share knowledge, exchange ideas, and stay in touch with people with whom you have a common interest makes us all a little richer. We become larger in ourselves when we remain a part of a bigger whole.
As I said above, Amazing Computing is celebrating its fourth anniversary and we are proud of the people we have come to know in the Amiga community and of the excitement the Amiga is currendy generating in video, animation, and presentation. AC is a result of the great efforts presented by a good many people. 1 thank you all.
