PXG - The Pascal Expert Generator
By Samuel H. Smith, Public Domain Material, Version 1.0, 4-Oct-85
This program allows you to prepare a set of rules for a
decision-tree expert system.
You teach the expert by repeatedly "Learning" new facts in the
interactive learn mode.
When you have your rules working properly, PXG will generate a
stand-alone expert program in turbo pascal!
This disk contains the following files:
PXG.COM The pascal expert generator
PXG.DOC Documentation for the pascal expert generator
PXG.PAS Source code for the pascal expert generator
PXG.INC Include file needed when compiling your experts
LANGEXP.KDB A knowledge base for a language selection expert
LANGEXP.PAS Generated source code for the language expert
LANGEXP.COM The compiled language expert example
MECHANIC.KDB The knowledge base for an auto mechanic expert
MECHANIC.PAS Generated source code for the expert mechanic
MECHANIC.COM The compiled expert mechanic example
Legal commands while running PXG:
