ROSIE (Rule-Oriented System for Implementing Expertise) is a computer programming language/environment developed for the Defense Advanced Research Projects Agency. ROSIE is designed specifically for developing expert systems, and its primary purpose is to aid the knowledge acquisition process. To this end, ROSIE assumes its most characteristic feature, an expressive and highly readable English-like syntax. This report constitutes a new reference manual and user's guide for the ROSIE programming language/environment. It consists of an informal yet detailed discussion of the syntax and semantics of ROSIE 3.0, including an explanation of the programming environment as a whole. The report supersedes all earlier documents describing ROSIE. A technical audience is assumed, but the introduction provides a comprehensive overview of the ROSIE language for those interested in a less technical presentation.
