Build-A-Fish 2.1
Copyright 1991 Virginia Marine Science Museum
Programmer - Mark C. Vang (VMSM)
The Build-A-Fish program allows the user to define physical attributes
of a fish and then the computer displays the fish. This program is capable
of generating 67 different fish. Each fish is described briefly. This
program is an interactive exhibit used on the floor of the Virginia Marine
Science Museum.
Computer requirements:
Build-A-Fish was originally written for a 4mhz XT computer with 256K RAM.
It has also been run on IBM compatible AT computers.
CGA graphics capability is required.
The program and all graphics files will occupy about 1.3 megabytes of disk
space.
Program description:
Build-A-Fish was originally written in GWBASIC.
It was compiled using QuickBASIC 4.5 in December of 1990 with enhancements.
The graphics files were also updated at this time to make use of the full
CGA color range.
Program operation:
Build-A-Fish incorporates a timeout feature which causes the program to
return to the previous menu if the keyboard is unattended. This
modification was included primarily for use at the Museum so that a
patron would always start at the beginning of the program and not where the
last patron left it. The program sets up simple timing loops to determine
how long it will wait. Since this program was written for use on a 4mhz XT
it was necessary to allow the user to change the timeout values. If you
were to run this program on a 12mhz AT with the values for 4mhz, you would
be bounced back to the main menu so fast you wouldn't know what happened.
To change the timing values, run TIMEOUT.EXE. This program is disributed
with the Build-A-Fish shareware package. TIMEOUT.EXE will allow you to
enter your own values for the timing loop and then saves it in TIMEOUT.DAT
which the Build-A-Fish program looks for when it starts out. Remember, this
value is NOT in seconds. If the Build-A-Fish program does not find the
TIMEOUT.DAT data file you will get a "FILE NOT FOUND" error message. Simply
run TIMEOUT.EXE to create the file and then run Build-A-Fish. Be sure that
you keep ALL of the Build-A-Fish programs, data files, graphics files on the
same directory/sub-directory of your hard drive.
Please see REGISTER.DOC for information on registering Build-A-Fish,
software upgrades and a list of programs which come in the Build-A-Fish
package BLDFSH.ZIP.
