[PHLSIM]README.TXT

This disk contains six files:

	1. Readme.txt - this file
	2. Induct.bas - BASICA source code for the INDUCT program
	3. Fast.bas   - BASICA source code for the FAST program
	4. Induct.exe - stand-alone executable code for INDUCT
	5. Fast.exe   - stand-alone executable code for FAST
	6. Phlsim.txt - text file document which describes the
			educational use of the two programs

 
Instructors should carefully read Phlsim.txt before trying these
programs in their classes.  Phlsim.txt also has references to other
articles, published and forthcoming, which contain more detailed
discussion about the educational purposes of these programs.

Please note that the source code is in BASICA.  These programs
can be run in the BASICA interpreter, but students will then
be able to read the rules of the systems unless the code is protected.

The programs are better used by students when they are compiled (and
the source code is not available to them).  The compiled programs,
INDUCT.EXE and FAST.EXE, can be run from the DOS prompt by typing
INDUCT or FAST, resp.  The programs have been run on DOS 2.0,
DOS 3.0, and MS-DOS 3.1.  They require an IBM PC, XT, or AT with a
color graphics adapter and color monitor, or a completely compatible
system (e.g., I have run them with no changes on a Tandy 3000).
They have also run on an AT with an Enhanced Graphics Adapter
and Monitor.

The programs have been compiled with Microsoft's BASIC Compiler
Ver. 1.00 and also with the newer Microsoft QuickBasic Compiler.
The *.exe files on this disk were made from the former.  I have
never tried the *.exe files on a machine with less than 512K RAM,
although they should run in considerably less memory.

Although FAST is a more interesting program than INDUCT, it is also
considerably harder to understand and work with.  I strongly advise
that one try working with INDUCT for awhile before starting with
FAST.
