Description:	Public domain implementation of an OPS5 interpreter. OPS5 is a programming language for rule-based production systems. A rule consists of pre-condition(s) and the resulting action. The system as a whole acts first checking the status of system in its working memory and matches the rules to see if there are rules that are satisfied, and then the action in one selected satisfied rule is executed. There is a commercial version available called OPS83. Please contact the author for information.
