The word is spreading around and I hope everyone is still getting ZMag without any problems. As stated last week, you can call XBN BBS if you were on the ZMag BBS and continue with your access without a delay or wait for validation. ST-Report is a bit behind in circulation due to some personnel problems. We have made arrangements with ST Xpress Magazine to publish ST-Report on disk and through GEnie. I will keep you all updated on our status. If you have any text submissions you are interested in publishing, Please upload them to XBN or Starbase I systems. I will be calling these systems regularly. This publication will begin a slow change during the weeks ahead. So, keep reading and watch. On the homefront, Kovacs child number 2 is still refusing to appear, however, it has positioned itself for a soon arrival. I stay with my prediction of 2-3/2-10...(you probably dont care, but it will be of interest to me....) Hmmmmmm Thanks for reading and for all the messages about supporting us. ______________________________________ Xx ANALOG CONFRENCE ______________________________________ Re-edited for ZMAG by Ron Kovacs TEXT OF CONFERENCE ON DELPHI REGARDING ANALOG BUYOUT JANUARY 17, 1988 Andy> I'd, first, like to welcome all of you attending this conference. My name is Andy Eddy and I'll be moderating the CO. Lee> First, ANALOG has signed contracts with a publishing company in LA. That company is LFP, Inc....Larry Flynt Publishing. We expect to have the next issues of both mags out in 3 weeks. Let me give a few words about the changes...First...Larry Flynt has little to do with daily operations of the company...as a whole. He will have nothing to do with the editorial contents of either magazine. Changes you will see include new (glossy) paper, a heavier stock inside as well as a heavier cover. More color pages thoughout, INCREASED distibution, Much improved service, and a steady frequency. What you won't see is ads for Hustler and the like. LFP, Inc. also publishes a Mens fashion mag, a running mag, a new automobile mag, a motorcycle pub and a Heavy Metal mag. With many more non- pornography titles on the way. Andy> Thanks, Lee. So the fears..that this will be anything like..Hustler will not materialize. This will remain the same Analog as before..but with some changes in the "production" end..not the editorial. Lee> OK. There WILL be changes.. Because I won't have to deal with such things (as much, anyway) as distribution...subscription problems, and production, I can spend more time on editorial...that goes for Clayton as well. Andy> So you don't see anything but beneficial changes for the mags? Lee> Actually, let me say this...the only way someone will know we are owned by another company is a small blurb on the staff page. As far as changes go, I expect an even more steady stream of quality editorial since it will be the main direction of our time working on the mags. Maurice M.> Okay. I want to get this subject out of the way now especially in light of recent messages in the forum. Certain people have hinted that there will be changes in the magazine because of whom the ownership is. The point, I think has been refuted. However, DF Scott has in recent messages hinted that several of us writers were in a "dillema" over the ownership change and might no longer write for ANALOG. I would like to put to rest any fears readers might have about mass-defection of writers by asking you, Lee, if you are aware of any other regulars "leaving" because of this ownership change. Lee> No, not at this time. Let me respond to your comments. While I don't whole heartedly agree with Larry Flynts views. I am looking at what that company can do for our magazines. They don't know ANYTHING about what we publish, they (LFP, Inc) are leaving us alone in what we do. To them profit is what they want, editorial content is 100% up to what we do. They'll make the magazine look better, distribute it better, and put out a quality looking product, it's still up to me, Clayton, Maurice, Charles Johnson, Andy Eddy, MAtRat and the rest to put out a good magazine in product. To answer Maurice's question, other than Scott, no one has more than batted an eyelash over the buyout in terms of who it is. After the intial shock wheres off on the buyer's name, they settled in and want to get back to work. Maurice M.> Good to hear. I simply wanted to address the subject because I wanted people to be aware that Scott didn't speak for all of us. I'll step down now. Lee> Last Monday is when Michael Des Chenes and I signed. We are waiting to get them back from LA now then it will be official. Clay> Anyone who is interested in the terms of publication and how to submit articles may send me a self-addressed, stamped envelope and I'll see that you get our writer's guidelines. You can send requests to the PO Box 23 address in the magazines for now. Andy> Also with Analog's liberal policy of letting programs go onto BBS's after 1 month from issue date (that is right?), everyone gets to see the stuff they publish. Clay> Yes, Andy. Mike Brown> Will we be able to get back issues of both magazines and disks as in the past? Or will these "Classic" issues become collectors items? Lee> Yes! LFP, Inc is purchasing our entire supply of back issues. Including disks, 8-bit Extra's and so on. We expect to offer disks at a lower price and the availability should be MUCH better. JIMGAR> Thanks. My burning question is WHY???? Wasn't Analog a profitable venture? Lee> WHY is a complex answer. First - WHY NOT? ANALOG was myself and a partner, Michael Des Chenes. As you may have noticed, Michael never spent much time on Delphi and while I have gone to over 100 Atari shows and ComDex's, etc., he has not. Michael has been bored doing the same thing for 7 years and wants to try something new. In addition, I couldn't see the company growing much further the way things have been, so this gives us a chance to expand greatly....plus I'll be working on new publications, both computer and non-computer related in the next few years. Also, LFP, Inc. offered us a very good deal...and who really knows how long Atari will keep going. This way I can expand on my interests and do other things along with the Atari field -- after all, I have been doing the for 7 years. A long time! JIMGAR> In other words, the whole thing got out of hand? Clay> A company can only grow within the facilities it has at hand. Lee> Right...We needed to expand, and as do airlines, insurance companies and so on. We were bought out to expand our capabilities. WHITEWIZARD> you said that the analog depends on the 8-bit...Does this mean that you might stop publishing in the future if the 8-bit fails (ANALOG, not ST-Log)? Lee> ANALOG depends on the 8-bit market ...Lets say that advertising right now isn't overwhelming and ANALOG would most likly take a new heading (orientation) in the event 8-bits REALLY dwindle. I could see a change happening probably this year some time... WHITEWIZARD> Would you combine ANALOG and ST-Log agian? Lee> Again, it is mostly up to the ANALOG staff, not LFP, Inc. Yes, I could see us doing one mag--but here is the problem. The ANALOG name is the best known, if we put in ST-Log then the mag becomes a general Atari mag again. If we kill ANALOG and continue ST-Log...well ANALOG has the more known name and that would be a mistake. Chances are ST-Log might have some 8-bit coverage...but that is all up in the air right now. When we are in place after a couple months we'll look at the whole picture. MADMODIFIER> With many software publishers spreading out to the Amiga..... Is there any chance that Analog might do the same? Lee> I have plans to do another computer oriented mag but can't say much (exactlly nothing) about it. MADMODIFIER> You mean we might see AMIGA LOG <grin>? Lee> No Comment. But I hope to have a new project out in late Spring. Mike Brown> I would like to suggest that you run some type of a readership poll in your first new issue to determine what your readership looks like now. Lee> Huh...in what way? Between ST and 8-bit? Mike Brown> Well I imagine that the complexion of the readership has changed somewhat. It might be worthwhile from a marketing standpoint. Lee> You mean between 8-bit and ST??? Sophistication? Mike Brown> Well that and just what people are interested in reading about. What their needs are "today". Lee> We have the "bingo" cards in the mag every month and poll those to see what people are using...however we have talked about doing another mail- in campaign...a more in-depth look. Remember that Delphi users are more into their machines than many other average users. Mike Brown> Maybe, but I guess my point was that at least in the 3 user groups I belong to things are in a state of "change". STeve M.> What direction will ST Log be taking in terms of content? General readership, programming, or what? Clay> I can't see much that will change in ST-Log. Is there something you WANT to see changed? STeve M.> No, just was hoping there were not going to be any drastic changes now. Thanks. Lee> I feel we have a good balance of information, sophistication and programs. I think Clayton, myself and our new west coast person will have more time to look at each issue well in advance and look at it's contents to see what blend of information it has...thus boosting the magazines quality...(not that it needs boosting <grin>) in addition, hopefully we'll add more pages too. Clay> The combination we've had in the past has worked out well, I think. I don't see any reason to change it. (More pages would be nice.) Lee> No, I certainly haven't seen any complaints about the balance of material. Keep in mind that I'm moving from New England (fresh air, no traffic, nice scenary) to LA (smog, Lots of Traffic and more smog) for the CAUSE. In other words...If I didn't see a tremendous potential in this I would do it! [Ed.

Contact me at the address at the end of the lesson. ------------------------------------ FEEDBACK: ------------------------------------ Since Lesson 1, I have received inquiries about what Disk Operating System (DOS) I am using. I am writing for Atari DOS 2.0s/2.5, as everyone with an Atari has, or has access to this DOS. Other DOS's allow variable names beginning with #'s, and other features. More discussion of DOS in later lessons. ------------------------------------ VARIABLES: ------------------------------------ Two common ways of using numbers in programs, are to use them as CONSTANTS, or in VARIABLES. When you simply use a number like 3, that's a CONSTANT, because it's just and always 3. It doesn't change. VARIABLES can hold different numbers or letters at different times in a program. For example, a payroll program, could use the variables EMPLOYEE$, RATE, HOURS, and SALARY. These would hold new data each time they calculated an employee's salary. There are two kinds of variables. 1. Numeric Variables (numbers) 2. String Variables (letters) Numeric variable names must start with a letter, and may contain up to eight uppercase letters or numbers (alphanumeric data.) No spaces are allowed. As a general rule, you should keep variable names short, but use names that suggest what they do. For example to set up a numeric variable to hold Fahrenheit temperature in a conversion program, you could call it FAHREN, FTEMP, F, etc. String variables hold letters, or words, sentences, etc. They must begin with a letter, and end in a dollar sign, as NAME$. A quirk of Atari BASIC requires that string variables be dimensioned before use. This is done with the DIM statement followed by the variable name, and the maximum length the computer should reserve storage for. For example: 10 DIM NAME$(20) This reserves storage for a name of up to 20 characters in length. If you typed 25 letters for input, it would only read 20. If you forget, you'll get an error message when you try and use a string variable you haven't dimensioned. More than one variable may be dimensioned by separating variable names with commas. For example: 10 DIM ADDR$(20),CITY$(20),STATE$(2) ------------------------------------ LET STATEMENT: ------------------------------------ The LET statement, assigns something to a variable. It could set X = 0, or NAME$ = Jack. The official form of the LET statement goes like this: 10 LET X=0 20 LET NUMBER=1024 30 LET TOTAL=NUMBER 40 DIM NAME$(25) 50 LET NAME$="George Washington" etc The way this ASSIGNMENT statement works, is that it looks for a variable name on the left of the equals sign. It will take what's on THE RIGHT, and put it into the variable on THE LEFT. Got that? It loads from the right, into the left. 10 X=256 (sets X equal to 256) 20 25 = SUM (*** WON'T WORK ***) 20 SUM = 25 (this is correct) 30 SUM = X (now SUM = 256) It happens that you don't need to put the word LET in there for it to work (how handy), and in fact it is nearly poor practice to do so. The 'hip' way to do it is: 10 X=0 20 NUMBER=1024 30 TOTAL=NUMBER 40 DIM NAME$(25) 50 NAME$="George Washington" We will use LET statements in EVERY program we write, but outside this lesson, probably never use the word LET again! Interesting tidbit. We'll see more examples as we progress. Note that spaces between variables, the equal sign, and constants, in the LET statement are optional. Atari BASIC is loose about this. Spread it out if it looks more readable to you, or eliminate spaces when you're running out of room in a 100+ character line. BASIC already has RESERVED WORDS that cannot be chosen for variable names. For instance, PRINT, STOP, END, SIN, COS, TAN, RND, INT, and others cannot be used for your variable names, as the computer already uses those words to call built-in functions. Remember to check for this in programs you just can't seem to de-bug. Next week Part 5 ______________________________________ Xx Atari News Update ______________________________________ ANTIC PUBLISHING INC., COPYRIGHT 1988 REPRINTED BY PERMISSION. ATARI GETS TOUGH ON TV BY Gregg Pearlman, ASSISTANT EDITOR In the wake of a Christmas season in which Atari Corp.'s video game sales were more than twice those of the same period last year, Atari plans to keep the ball rolling by launching a major first-quarter national television advertising campaign featuring six new commercials, according to Michael Katz, president of Atari's electronics division. The commercials will be aired in the top 30 markets in children's and prime-time viewing hours and will include syndicated and cable programming. Katz said that first-quarter spending will be comparable to what Atari spent in the fourth quarter of 1987 when the company sold out of two of its three game systems, the new XE Game System and the older 7800. The new Atari 2600 commercial, like the previous one, uses rap music while heavily promoting the new games available for the 2600. The new XE commercials include a testimonial/ endorsement commercial presented by the presidents of four computer game companies; a commercial comparing Atari's baseball game with Nintendo's; and three more promoting the range of new games for the XE. Atari also announced new playable, self-running point-of-sale display units for the 7800 and XE systems, available at no charge to retailers. ATARI PC: MYTH OR FICTION? January 6, 1988 -- "I'm sure that I will never see" "Atari's duplicate PC..." That song's been sung for months. There's been little evidence of the IBM clone Atari started showing a year ago. But according to a classified advertisement in the San Jose Mercury News, Atari is seeking a "Production Development/Sustaining Engineer for our growing line of PS2/PCAT/PCXT systems." So keep on your toes -- it may not be far away after all. ATARI NABS COUNTERFEITERS December 17, 1987 Agents of the U.S. Customs and U.S. Marshals Services seized 2,000 counterfeits of Atari's 2600 video game system at Terminal Island in the Port of Los Angeles on December 17. The imitations were manufactured by Fund International Co., Ltd., of Taiwan, and distributed in the United States by P.S.D. Inc. of Canoga Park, California. VIRTUSONICS LICENSING AGREEMENT December 16, 1987 Virtusonics Corp., creators of the Desktop Performance Studio, has entered a development and licensing agreement with 2nd Mate Systems, a marine navigation software systems company, to adapt and interface its Virtuoso software technology with 2nd Mate's computerized marine navigational systems. Boaters will now be able to plot their courses and positions on computerized charts using computers (such as an 8-bit Atari) and a monitor or television. A review of the Desktop Performance Studio and an in-depth article about Virtusonics and the Virtuoso Software technology will appear in the April, 1988 issue of Antic. ATARI WINS SHOOTOUT VS. NINTENDO December 15, 1987 A U.S. District Court Judge denied the request of Nintendo of America to halt Atari Corp.'s television commercials that said that more games could be played on the Atari XE Game System than on the Nintendo, according to Reuters. Nintendo had contended that the ads were false and misleading, but Atari was "confident of the outcome," according to Michael Katz, Atari's president of entertainment electronics. "The commercial was hard -hitting but truthful, and we proved it," he said. The XE Game System runs all cartridge -based Atari games, and a disk drive can be added to run all disk-based Atari games. ______________________________________ Xx REVIEW GREAT AMERICAN CROSS-COUNTRY ROAD RACE ______________________________________ BY LAWRENCE R. ESTEP Activision has produced many great programs in the past few years,and this review is of one of them. This piece of software is one of many classics from Activision software. If you love a good challenge, then you'll love this game! The object is to race from a city on the West Coast to a city on the East Coast in a time that will place you among the top contenders. You can also race in smaller races, from one state to another nearby state to gear up for the final challenge. However, in all races you have to be ready for unexpected problems, such as road construction, inclement weather, and of course the dreaded radar-detector and speed traps! This game is unlike most, as this one is always a challenge,no matter how many times you play it. There is always a new group of racers to compete with, and always a new problem that comes up! This is one of the best racing programs I've ever seen! The graphics are great, and the competition is thrilling! Check out this fine program from Activision, and continue supporting this company, so they can bring us more programs like this for years to come! ______________________________________ Xx MTOS ______________________________________ by Tom Hunt MTOS (C) 1988 SAMPLER MTOS is a revolutionary new operating system system shell for Atari 8-bit computers with 256k(+) of internal memory. This text is from the MTOS sample with some of it's most important features installed. The features of this sampler are as follows. ALLOWS MULTITASKING OF 2 BASIC USER PROGRAMS ATARI DOS 2.5 COMPATABLE SUPPORTS GRAPHICS MODES 0-6 GETTING STARTED WITH THE MTOS SAMPLER Copy MTOS.COM onto an Atari dos 2.5 disk that does not have any RAMDISK.COM on it. When this is done, turn off the computer for a few seconds, and turn it back on, with the disk you just created in D1: drive. Boot without holding down the option key (basic enabled). It is suggested that RAMDISK.COM is not on the dos boot disk, since MTOS uses the extended banks, and any files in your ramdisk might get corrupted. Type "DOS" from basic's "READY" prompt. When you get to the DUP.SYS menu, type "L" for binary load. At the next prompt (for the filename,) type "MTOS.COM". After MTOS is done loading, you should be looking at the Executor (aka Exec, task-manager) screen. You can now initialize 2 user tasks, which in this sampler, is limited to basic. To attach (view) a task, choose the "view" option, choosing from the list of active tasks. Limit your viewing to tasks 1 thru 2, since tasks 3 thru 6 are non-existant in this sampler version. If you followed the above instructions, you should be looking at basic's familiar "READY" prompt. To detach from a task, just plug your joystick in to the second joystick port, and press the button. You will automatically reattach to Exec. MTOS stands for M.ulti-T.asking O.perating S.ystem. It is more properly called a shell, since it works with your dos and the Atari o.s. rom. It offers the Atari 8-bit owner a new dimension of computer enjoyment- the ability to run more than one program at one time. I have designed MTOS to place as few constraints on people wanting to write programs that will run under MTOS as possible. There are a few constraints, however. Your programs simply have to be "well behaved" in that they can't indescriminately go poking around in memory, since our CPU doesn't support protected modes.
