  OPS5
       
           A programming language for rule-based {production
          system}s.  A rule consists of pre-condition(s) and a resulting
          action.
       


          The system checks its working memory to see if there are rules
          whose pre-conditions are satisfied, if so, the action in one
          selected satisfied rule is executed.
       
          There is a {public domain} implementation of an OPS5
          {interpreter} written by Charles L. Forgy 
          in 1977.  It was first implemented in {Lisp} and later in
          {BLISS}.  It was also ported to {Common Lisp} by George Wood
          and Jim Kowalski.
       
          {CLIPS} is a language for writing {expert system}s, with some
          of the capabilities of OPS5.
