摘要: Prolog-X is an implemented portable interactive sequential Prolog system in which clauses are incrementally compiled for a virtual machine called the ZIP Machine. At present, Machine emulated by software, but it has been designed to permit easy implementation microcode or hardware. running on software-based emulator provides performance comparable with existing interpreters. To demonstrate its efficiency, compatibility, and comprehensiveness of implementation, used compile run several large applications programs. Several novel techniques particularly areas representation therecordx database, selection clauses, compilation arithmetic expressions.
