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

Shrink [BASIC Program Compressor]MISSING

Gulf States Computer Services

Shrinking Basic Well-commented programs facilitate debugging and clarify program logic. Once you're familiar with a program, however, these lines lose their usefulness and waste memory space. Shrink ($24.95) compresses Basic programs to the smallest possible size without altering program logic and data. It removes remarks and unnecessary spaces, and combines statements into as few lines as possible. You can then run larger programs and execute programs faster. If you need to edit a program, Break ($19.95) puts each statement on its own line. For even clearer listings, Insert ($19.95) puts spaces before and after each Basic operator and key word. All three utilities execute from the overlay area of your operating system while the Basic program resides in memory. No saving and loading is necessary. Load the program once, then insert spaces and break lines for corrections, or shrink it and run it from RAM. The programs run on the Models I, II, III, 4, 12, and 16. A complete package with all three utilities is $49.95 from Gulf States Computer Services, 10039 Bissonnet, Suite 130, Houston, TX 77036, 713-270-9003.

Shuttle II [Disk]MISSING

Molimerx Ltd

M1

SHUTTLE II-A COMPUTER MODEL OF THE COLUMBIA FLIGHT This program is a simulation of the shuttle flight of the space vehicle Columbia. The entire flight is covered, proceeding from the initial countdown, through the launch, and into orbit. From there you may drop out of orbit, fly the shuttle through the atmosphere, to a safe landing. You will, however, need a lot of skill to do it! An important feature of this program is that it can be started at any of three points. Either at countdown, while the Shuttle is in stable orbit around Earth, or shortly before landing enabling you to clock up your practice hours before the maiden flight. Your objective is to guide the Shuttle, and to do this you are provided with a number of different controls. The thrust of the ship can be varied on a scale or 0-9, the craft may be rotated vertically in either large or small increments, there are controls for jettisoning your fuel tanks and controlling your undercarriage. To achieve a stable orbit you must be able to control you height, horizontal speed and vertical speed. Skilful use of the orbiter motor in conjunction with the altitude controls will achieve this result. One remarkable feature of this simulation is that it includes a full atmosphere with a density that closely follows that of the real atmosphere. As the density steadily and rapidly increased below about 55,000 yards, the craft begins to experience both life and drag similar to an ordinary aeroplane. The drag starts to slow it down, whilst the lift allows the craft to start to fly. This is a very tricky part of the flight as several things can go wrong. If the Shuttle is too 'nose up', it can experience enough lift to shoot it back into space. Alternatively, if the opposite occurs, the G-Force will rise above tolerable values making the pilot unconscious and then, if allowed to continue to a level of 10 G's, the craft itself will disintegrate. These cheerful remarks apply, incidentally, apply throughout the flight. The secret is to loose speed and height in a controlled manner. Apart from the attitude controls, the lift and drag can be controlled be setting an air brake on or off and by setting flaps for extra lift. The emphasis in this program is in presenting as realistic as simulation as possible. It combines the control of a space vehicle with that of an aircraft and gives the user the best of both worlds. It is not a graphic simulation. The joy remains in controlling the orbit and landing the craft successfully, rather than presenting a graphic representation of an orbiting Shuttle.

Simple Interest for Days [Part of LIBRARY 100]MISSING

The Bottom Shelf

LIBRARY 100 The LIBRARY 100 from TBS is without doubt the greatest software bargain ever. Released in November 1978, it has sold thousands in 44 countries. Written for the TRS-80, LIBRARY 100 contains 100 programs on five tapes. Most of the programs can be run on a 4K, Level II computer. Designed to be a basic computer library, it provides a series of programs over a broad range of topics. All programs but one are written in BASIC and can easily be modified to suit your own purposes. 'The program mix is eclectric, interesting, and curious If I had a Level II TRS-80 and one or more grade-school children, or if I were a hardcore software collector, or if I had little software and wanted to get a lot of it with a minimum of bother, I'd buy the Library 100.' Stephen Gray, Creative Computing, April, 1979. ' a basic computer library for the hobbyist, parent or businessman.' Kilobaud Microcomputing, December 1978. The programs are spread over five general categories; Finance, Education, Graphics, Home and Games. As an added bonus, the LIBRARY 100 contains Tiny PILOT, a condensed version of the high level language primarily used in education. It is perfect for teachers, parents, students and sales trainees. Using only six commands, even a child could be programming in minutes. The other programs are as follows: FINANCE: Present Value of Future Sum, Simple Interest for Days, Future Value of Present Sum, Amortization Schedule, Interest Rate-Compound Interest, Interest Rate-Installment Loan, Days Between Dates, Term of Installment Loan, Present Value of Series of Payments, Real Estate Investment Analysis, Nominal-Effective Interest, Internal Rate of Return, Future Value, of Regular Deposits, Regular Deposits for Future Value, Depreciation (Amount, Rate, Salvage Value, Schedule), Bond Present Value, Bond Yield to Maturity, Sale-Cost-Margin-Day of Week, Moving ad.

Simple SortMISSING

The Alternate Source

SIMPLE SORT What are the best qualities of a sorting utility? The sort must be fast. (Simple Sort is written in Z-80!) The sort must be efficient. (Simple Sort occupies less than 3K of machine code and requires less than 1K for buffers!) The sort must be kind to the diskette. (Simple Sort does all its sorting in memory, with a minimum of reads and writes!) The sort must not use any extra storage space. (Simple Sort does not require any intermediate files!) The sort must be easy to use. (Simple Sort only needs to know the bare particulars!) Simple Sort -it's easy, it's fast and it's efficient! The perfect answer for single drive owners, and great for dual drive owners who prefer to use formatted-only diskettes! $79.95 on diskette with manual.
