SPACE Newsletter March 1995 ..

Newz From The Prez

by Nathan Block Nathan has failed again to submit his article in time for this publication! His article has to be submitted to me two weeks before Club Meetings. This gave him two weeks to put together an article. I find it very hard to believe that Nathan has absolutely no time to get an article together and get it to me by the two .week deadline. The Editor DOM Info by Terry Streeter Terry has failed to submit DOM info to me in time for the newsletter. It appears Terry also has absolutely no time to prepare any kind of DOM Info for the Newsletter. The Editor Treasurer's Report by Grey Leitner

The February SPACE meeting produced quite a mixture of topics for discussion. First I would like to assure Nathan that we all are behind him, and we appreciate all the input and time that he can spare for the Club. I don't think anyone could do a better job, and we all know and understand that the hectic life you lead makes it impossible for you to do all the things you would like. So Nathan as long as you still have the desire to be President, you will have my support 188 percent. Enough said! Now that the SPACE newsletter is going to be available in the near future on the BBS, I was really hoping to get some pointers from the demo that was planned for the February meeting. Unfortunately, Mike and Sherm had unexpected problems with the modem and they had to put on hold the BBS demo until the March meeting next month. Anyone who has a modem and does not take advantage of it· s capabilities (like myself) should attend the next meeting on March 10 to find out what your missing.

l .

Also, now that the Club has access to a large library of ST disks, there was a great deal of discussion on how to best use this format. Only a few of us in attendance owns ST's, so we have to find a way to get more ST users to attend our monthly meetings. Surely the old MAST members must still want a forum for their machines. Well I suppose I should say something about the financial situation of the Club since I am the Treasurer and that is why I am writing this article in the first place. The Club has been, . • ~ very well the last couple of months and once again our receipt~ were greater than our expenses. We took in a total of $186.88 for February which included three memberships, DOM and blank disk sales. Our only expenses for the month were for the February Newsletter and the January BBS phone bill totalling $39.87. We netted an additional $66.13 for the treasury and our balance now stands at $531.88 which I think is terrific. We will be getting billed for the first quarter rental of the hall ($98.88), but if we can keep getting new members and membership renewals we will have no problem in keeping our Club financially healthy. Thanks for a great February meeting and I will see you all next month. I really would like to hear some feedback from those of you who attended the Midwinter Madness show since I did not make it this year. I'm sure it was a great success and I probably missed out on some good deals. January Minutes of SPACE 1. The meeting was brought to order by the Vice-President, Sherm Erickson, at 7:30pm. 2. The Treasurer ' s report is found in the January 1995 SPACE Newsletter. The current balance was $374. 3. Old Business: The BBS was moved to Mike Fitzpatrick's home. The phone number is; (612)427-4317. Mike asked that the members be patient as he is combining his BBS, The Book Nook, with SPACE to have two boards on one system.

New Business: a. It was suggested that the newsletter be posted on the BBS for those who have and use modems. b. A demonstration of using the BBS is scheduled for the February SPACE meeting. c. It was requested that a demonstration of Atari Writer and Atari Writer+ be given. d. An invitation letter and our current bylaws have been sent to the membership chairman of the former MAST computer club, inviting them to join us at SPACE. e. Mid-Winter Madness was brought up. It was asked if SPACE were to have a booth and who would volunteer to represent SPACE at the booth. Sherm Erickson, Roger Mier, and Mike Weist indicated that they would man the pooth. To any other member please feel free to be there anii~.\.g out at th~ SPACE booth. ~ -~ f. External Club activities were discussed; with the following suggestions to be explored: 1. Volunteer(s) to visit other Atari Clubs as a representative of SPACE. 2. An individual to represent SPACE at one of the national Atari shows in Indianapolis, IN or Charlotte, SC, etc. 5. David Pascal Zimbal, president of the former MAST computer club, brought down seve~al boxes of MAST DOMs and other ST items of interest. Roger Mier is sorting and cataloging the material. Thanks Roger for the time and effort. 6. The meeting was adjourned at 8:30pm.

general consensus of the members pres agreed with her and expressed appreciat1 for what Nathan has done thus far. Sherm Erickson, Vice-president asked Mik Wiest to plan some club functions. Mike tentatively agreed to do so. Continuing Business: The BBS will be finalized this month when the SIG_Files will be sorted out and reloaded on the BBS. The ST software was sorted out by Roger Mier, MANY THANKS I I , and he reported the status of the software and printed matter. The redundant DOMs will be purged. The ST DOMs will be sold at the same price as the Classic 8-bit DOMs . Sherm Erickson challenged the club to discover where other Atari clubs meet so that we can pay a courtesy visit. Mike Fitzpatrick reminded the club about the occurrenc~ that _are _!lt_ill happeqing in the Atari community . The club is going to do an inventory of ALL equipment and software. Please bring a new or like new Cub style tote box to the next meeting for storage of club materials. The meeting was adjourned at 8:20pm.

Mid Winter Madness Show Blaine, Minnesota Feb. 11, 1995 Could weather couldn't keep Atari DieHards from the Mid Winter Madness Show in Blaine, Mn. Several members from the Space Atari Club showed up. Sherm Erickson, Rich and son, Roger Meier, Tony Walsh and others were there. Lance Ringquist and son manned a booth at the show, also Mike Schmidt and his son and I manned another booth. Both of the booths had Atari Space club literature, Mike's booth also was set-up for people to try Atari software. One visitor was surprised to see Atari at Mike's booth and said II Atari I can't believe it, I had Atari when I was younger. Mike told him to play around with some of the programs. Lance's booth had Atari equipment which included software and hardware for sale. Mike and Lance's were good coverage to advertise ATARI. Let me tell you, when it comes to electronic shows which include Mid Winter Madness. Hamfest. and the Amateur Show a person wants to buy everything at these shows, but a person's wallet puts a stop to that~ Atari software and hardware wasn't plentiful at Mid Winter Madness show, but there were a few Atari Items for sale. The show was fun and I am looking forwards to the next show on October 28, 1995 at the St. Paul Civic Center. So mark your calendars!!!!! Lastly, a thanks goes out to Mike Schmidt and Lance Ringquist and kids for promoting SPACE!! See you all next Space Meeting. Mike Weist Two-Minute Know-it-All Exhibiting Problems Birds of a feather••• die together? Forty-four black footed penquins at the Los ~ngeles Zoo have joined that big flock in the sky over the past ten years; a population that once reached 27 is down to four. Most of the pen_q uins died of diseases that were aggravated by stress due to heat, poor nutrition and competition (there are now three males competing for the attention of one female), experts found. Also, unknown predators have gotten into the open enclosure and killed six of the penguins.

"It would appear ••• that it is the wrong exhibit for the species and, indeed, it probably is the wrong species for the L.A. Zoo," says Gretchen Wyler, president of the animal rights group Ark Trust. Weird News According to an October report from U.S. Rep. John Dingell, defense contractors recently billed the federal goverment for such inappropriate employee perks as $263,000 for a Smokey Robinson concert; $20,194 for "professional quality" golf balls; $63,000 for crystal decanters for employee awards; and $17,000 to hire referees and umpires for office sports leagues. An Associated Press story on body branding revealed that the idea of having one's skin artistically sear .,- as a "personal statement" is growing in popularity, especially in San Francisco. The branding customer endures from one to hundreds of one-second "strikes" with a blowtorchheated, white-hot galvanized sheet metal design selected or created by the customer. Each branding scar takes siz weeks or longer to heal. One customer interviewed by the San Francisco Examiner said she got a large, elaborate African sunburst on her _lower back because she thought it would help "keep me more centered" because "I couldn't get in balance with myself."

+----------------------------------------+ Larry's ACTION! TUTORIAL

+----------------------------------------+ Overview I

As seen before, when declaring variables, you also have an option to assign that variable to a specific address. Another option allows you to assign a value to it at compile time.

From the top, programs in Action! are made BYTE ch=764 assigns an address up o't procedures and functions which are BYTE spd=[3] ; assigns a value called upon to do portions of a programmed task. Usually, the parts of a program You need to use some sort of compiler or that must be done repetitively, are coded numeric constant in the assignment option. in separate procedures and called when Any numeric or compiler constant works! needed. Also, certain tasks that are This can lead to some interesting results: common among all programs, are also often written as separate p~ocedures and then PROC SeeFormat() included in each program as desired. The BYTE lsb , msb reading of the keyboard, may be an example CARD num=lsb of a task that could be written as a BYTE function, and included in any program that PrintE("LSB/MSB program O=exit") - - do needs user input from Th·~·•·k~yboard.- The Action! system makes re-using routines Print("Enter a number>") very easy to do. num=InputC() PrintF( 11 %U > LSB=%U MSB=%U%E", Following along with the Action! manual, num, lsb, msb) Language section, the manual uses special PutE() notations which you should read about. You until num=O might remember seeing them from an earlier ad issue. Next comes Fundamental Data Types RETURN which are BYTE, CARDinal and INTeger type variables or constants. It may help to In this program, the variable ·num· is remember, the variables invariably change assigned the same addresses that are used during program execution, while constants for 'lsb' and ·msb·. Once 'lsb' has been consistently remain the same. A ·score· declared, its address becomes "fixed", the variable might always be changing while 'lsb' identifier is assigned a specific a constant number ·5· will not. address. Because its address is now a compiler constant, it may be used later, To let Action! know you want to use a where ever a compiler constant is allowed . named variable, you must declare it using Its the fixed address that is used in the one of the fundamental types. declaration of ' num. BYTE w,x CARD y INT z Both ·w· and ·x · are 8-bit values. They use one memory location to store values in. Their value may be 0-255. The CARD y is a 16-bit variable, it uses two memory locations in the 6502 LSB/MSB format. That is, if ·y· is assigned to address 1536 (Ex CARD y=l536) then the least significant byte will be in address 1536 while the most significant byte will be in address 1537. CARDs hold any value from Oto 65535. INTeger variables are 15-bit values, with the most significant bit used as a sign bit. INTegers hold the values from -32768 to 32767.

As you can see from above, the compiler usually i-gn.ores any spaces yeu may want to use. An exception to this is while trying initialize a string. Read the LANGUAGE section of the Action! manual, typing in their program examples. This will get you familiar with using the Editor, Monitor, Compiler and language.
