I am looking for two things.  

First, I am looking for any information on fuzzy prolog products that exist 
in either research or commercial markets.  Use would be at a University, for
development of expert system prototypes.  Any information/leads appreciated.

Second, I am looking for public domain sources for a prolog interpreter or 
compiler.  As a part of my PhD research, I'm interested in the possibility
of developing an expert system development environment that accommodates
fuzzy sets/logic/measures.  Either/both those defined as primitive
operations in the rules generator, inference engine, operators, etc and
those called "Subroutine-like".  

Information, references, etc would be appreciated.  Code of any type would 
cause wild exultations from the Southern Tier of New York.  YACC input, LEXX 
source, C routines, PC assembly language hacks, SunView front-end definitions, 
etc.  Give me your tired, I'm poor.

Thanks folks.  Happy networking.

I'll post a compendium of the results to comp.lang.prolog and misc.wanted.
