Aquarius Prolog is a high-performance, portable Prolog available free in source and object form from UCB, USC, and DEC's Paris Research Laboratory. The compiler is built around the Berkeley Abstract Machine (BAM) optimization for general-purpose machines. An interpreter simplifies program development. The run-time system is similar to Quintus Prolog, but with two kinds of destructive assignment. Current platforms include ULTRIX, RISC/os, SunOS, and HP-UX. Send a "get aquarius-info readme-full" or "readme-enduser" message to listserv@acal-server.usc.edu for more information, or a "get aquarius-info license" message to arrange free access. Send a "sub aquarius-prolog your name" message to joint the mailing list. Or contact aquarius@acal- server.usc.edu. [Peter Van Roy (vanroy@prl.dec.com), comp.ai, 4/1/93. Bill Park.]
