Open Prolog: Prolog interpreter for the Apple Macintosh

Open Prolog (OP) is a Prolog interpreter for the Apple Macintosh. It follows the so-called 'Edinburgh' syntax and supports most standard Prolog features, including Definite Clause Grammars. OP includes a debugger, good syntax error detection, and a flexible text editor. It is reasonably fast, and can execute large programs. Extra predicates can be added via drop-in external predicates, in a manner similar to Hypercard's XCMDs.
