[comp.lang.prolog] Expert System shell needed

dwr@lear.cs.duke.edu (David W. Reed) (03/06/90)

I am going to teach a short course on Prolog and expert systems to bright
high school students.  What I would like to find would be a good, simple
expert system shell that I could use as an initial demonstration.  It does
not need to be written in Prolog (I don't really care about the coding).
Does such a beast exist in either Freeware or Shareware form?
Any tips (or actual software) would be greatly appreciated.
