Help categorize the TRS-80 software archive
Nearly 30,000 programs, and almost none of them say what kind of program they are. Mark whatever you recognize. Pick as many words as fit — a game that teaches arithmetic is Game, Math, Education — then send the page. Everything is reviewed by hand before it goes anywhere near the archive, so a best guess is worth more than a blank.
Important Note: Do not do multiple entries of the same program. If you flag Super Nova by Big Five once, all Super Nova by Big Five entries will get updated. No need to waste your time flagging each Super Nova

Transparent Sort [Original]
transort.zip
Making Transparent Sorts Visible Pulse Software's Transparent Sort program is a graphics demonstration of the Shell-Metzner sort, an efficient Basic sorting subroutine. Although the subroutine is only 16 lines long, how and why it works can be a mystery to beginning Basic programmers. The Pulse program shows the compare/swap process as it happens, with a display of 26 letters being sorted into alphabetical order. Arrows indicate the letters being compared, and a top-of-screen display shows a continuously updated table of statistics and variables. A comment at the bottom of the screen explains the line being executed. The Level II program is available on 16K cassette ($14.95) or 32K disk ($19.95) for the Models I/III. For more information, contact Pulse Software, P.O. Box 1086, Freehold, NJ 07728.

Trashman is an arcade-style game for the Model I and III with 16K which tests your skill as you guide a little 'critter' from the Coalsack Nebula around the halls of the Deneb IV Haladay Inn devouring the trash left behind by careless guests. While you are avoiding the alien pets that also have been left wandering the halls, search for Dr. Peppo's Elixir of Health and Vitality and become 'Super Trashman!' From Creative Thaumaturgy.

Trashman Utility [Set 1][Dual Boot][Original]
trshmanm.zip
DOES STRING COMPRESSION HAVE YOU TIED UP IN KNOTS? LET TRASHMAN CLEAN UP THE MESS! TRASHMAN is a machine language utility for the TRS-80 Models I and III. It was written by Glenn Tesler, the author of FASTER, and can reduce BASIC's string compression time by 95% (see table below). # STRINGS SECONDS DELAY NORMAL TRASHMAN PERCENT IMPROVEMENT --- --- --- --- 250 11.8 0.7 94 500 45.8 1.6 96.5 1000 179.6 3.5 98 2000 713.2 7.8 98.9 WHAT'S STRING COMPRESSION? When a BASIC program changes a string (words, names, descriptions), it moves it to a new place in memory, and leaves a hole in the old place. Eventually, all available memory gets used up and BASIC has to push the strings together to free up some space. This takes time. Lots of time. The computer stops running for seconds or minutes, and you may even think it's 'crashed'. The keyboard won't work, and until all the strings have been collected, you just have to sit and wait. Then things run for a while, until string compression is needed again. And again. If you're using your computer for business, that wastes your money. If you're using it personally, it wastes your time. WHAT'S THE SOLUTION? As soon as you start using TRASHMAN, those delays almost disappear. It uses less than 600 bytes of memory, plus 2 bytes for each active string. It works with other machine language programs and with all major operating systems. It's easy to use, comes with complete instructions, and can be copied to your own disks. WHAT'S THE CATCH? If a BASIC program uses only a few strings, very little time is wasted in string compression, and TRASHMAN won't be helpful. But, if hundreds of strings, including large string arrays, are used, TRASHMAN is just what you need. Ask your software dealer for TRASHMAN, or order directly on our toll-free number. The price is just $39.95 (plus sales tax in California). (All timings done on TRS-80 Model I, Model III 15% faster, but pct. improvements identical. Listing of timing program available on request.)

Treasure Quest

TREASURE QUEST TRS-80 by Luke Buxton If you've ever wanted to captain the trackless seas of the world in search of riches without measure, with a band of treacherous dogs who happen to double as your crew, then this game should act as a most effective substitute. As captain of the 18th century sailing ship Zombie, you have come half a world in your quest for treasure. Your journey has brought you to the nefarious Blood Straits, and perhaps to a rapid death as well! In your favor are accurate chartings of the area, a dependable navigator, and a seasoned crew. In a negative vein, however, the Blood Straits is an area frequented by both violent storms, and an unsympathetic British Navy, which may mistake you and your men for pirates. A fickle crew and a rapidly approaching hurricane season round out your problem roster! TREASURE QUEST consists of your inputting a series of commands into your microcomputer as you go about searching for buried or sunken booty. A detailed instruction booklet is included to clarify and expound upon the various situations that you will encounter, along with advice and hints to aid you in your search. Each game begins differently, so you are assured of many hours of seafaring fun!

Treasure TroveMISSING
TREASURE TROVE - SEARCH THE DUNGEONS FOR TREASURE TREASURE TROVE is a type of adventure game (note the small 'a') which can be played by 1-3 players. Although it is a familiar theme in that the player or players must search dungeons and corridors for treasure, this program does have a lot to recommend it. The dungeon is made up of a block of 100 cells on four levels. The instructions include two sample player sheets, the first is made up of a map of one level and the second a map of all four levels. Thus the player can map his progress as he goes. The winner, of course, is the first person to retrieve a set amount of treasure and get out alive. In your search for the elusive treasure, you will have to fight monsters of varying strengths, avoid numerous traps, and use the full potency of the 6 magic items. The good news about this game is that all is not lost if you are killed. TREASURE TROVE is a three generation game, this is to say, if you get clobbered your son inherits your treasure and may continue the family quest. This program, as supplied, is compatible with Disk Basic and a customer may transfer it if he wishes. Memory Requirement 16k TRS-80 Tape Model 1 & 3 11-1907

Trend AnalysisMISSING
Market Trend Analysis The Trend Analysis program offers the Model I- or III-owning investor the ability to create and maintain files of historical data on stock and commodity prices, market averages, trading volume, interest rates, put and call activity, stock index futures, or any other data of interest. It can make calculations to help the user determine the major trend of the series, as well as calculate the deviation from the trend of the data itself or any moving average. The program lets you create and update files from the keyboard, read data from and write to disk for storage, combine two or more files or parts of them, or examine any part of the file on screen. You can calculate up to two moving averages with periods of your choice, determining the percent deviation of one from the other, or a time-weighted moving average in which the most recent data has the greatest weight. Data and the various averages can be printed; six different options let you use your printer to draw graphs. Four and a half years of NYSE Composite Index daily closing prices, from early 1978 to late 1982, are supplied, as is a user's manual (available separately for $12). Full operation requires 48K, two disk drives, and a printer; the program will run with some modification in 32K. Price is $37.50 from Harley D. Wilbur, 9709 Elrod Road, Kensington. MD 20895.

You can use the munched data you got from Seasonal, or some other data, and feed it to Trending. Trending also takes a bunch of data from a particular operation, but it uses it to predict trends. It uses three different common methods to predict the future path that the operation will take, and you get to pick the one to believe. If you only have 16K of RAM, limit your data input to Trending to 95 entries (Model I) or 85 entries (Model III).
