The parallel logic programming language PARLOG is now available for the Apple Macintosh (TM) and IBM-PC families of microcomputers. Two new products -- MacPARLOG and PC-PARLOG -- have just been released, to coincide with Addison-Wesley's recent publication of the tutorial book "Programming in PARLOG" by Tom Conlon. MacPARLOG and PC-PARLOG are full implementations of PARLOG, including both parallel and sequential operators, "deep" guards, control metacalls, and a wide range of primitives. Other features include: * A "lazy" incremental compiler. * A concurrent window-oriented debugger. This includes features analogous to those provided by Prolog debuggers: (no)trace, (no)debug, (no)spy, etc. Traces the events: CALL, SUSPEND, RETRY, REDUCE, SUCCEED, FAIL. Each process is traced in its own dynamically-created window. * Automatic display of incrementally-generated variable bindings in independent windows. MacPARLOG is fully integrated into the Macintosh WIMP environment, while PC-PARLOG provides a more conventional command-style user interface. Both systems are inexpensive and are especially suitable for educational and experimental use. For full details write to: Parallel Logic Programming Ltd.
