I am interested if anyone has compared these two prologs; what are their relative merits? Paul -- -- Paul Kirkaas kirkaas@cs.ucla.edu

SICStus Prolog is in general much better than SB-Prolog: it's faster, has a garbage collector and stack expander, and has much better support. It also supports primitives such as freeze/1 that are unavailable in SB-prolog. Also, I believe that it's practically free for educational institutions. -- Saumya Debray CS Department, University of Arizona, Tucson internet: debray@cs.arizona.edu uucp: uunet!arizona!debray

SB Prolog: never mind the quality, feel the price! (It's free.) SICStus Prolog: it isn't free, but put it this way: I can't think why anyone who actually wants to use Prolog for serious work would prefer SB Prolog to it. It hews much closer to the `de facto' `Edinburgh' standard than SB Prolog (Saumya Debray, on whom be blessing, wrote that one of the privileges of an author of free programs is to indulge his own taste). Performance is much better. As in really rather good (even if you haven't got a 68020 and have to use C-interpreted code rather than native code). It doesn't fall over as often as SB Prolog. It has a rather crude form of coroutining (everything you need to build more powerful schemes). If you can't afford a commercial Prolog, SICStus Prolog is the best I know of. -- Fear most of all to be in error. -- Kierkegaard, quoting Socrates.

Sepia is not yet well known, but it is an alternative that should be also considered. It has all the features mentioned with SICStus, plus some extras, e.g. the graphic interface for X and SunView, synchronous and asynchronous event handling, constructive negation, declarative corouting etc. I can give more details to everyone who is interested.
