I am planning to use an expert system shell, that is CLIPS ( http://www.ghg.net/clips/CLIPS.html ), with PureBASIC.
CLIPS has a dll, too (http://ourworld.compuserve.com/homepage ... ipstuf.htm).
There are also some interfaces for CLIPS such as PyCLIPS (Python interface) but since I am a PB fan from now on (

Any comments? Suggestions?
