ESL Prolog-2 (PD Version): Good performance public domain
(limited) version of a Prolog for MS-DOS systems.
lang/prolog/impl/prolog/eslpdpro/
ESL Prolog-2 (PD Version) is a public domain Prolog interpreter for
IBM PC (MS-DOS) systems with good performance. It deviates
slightly from Edinburgh standard (strings "like this" are not lists
of ASCII codes), but you can add a declaration that makes it fully
Edinburgh-compatible. (To do this, add the line
:- state(token_class,_,dec10).
at the beginning of the program.)
ESL PD Prolog is a more limited version of the commercial version of
the interpreter, which is available from Expert Systems Ltd. of
Oxford, England (see contact below). [Note: As of 11-NOV-94, ESL
Prolog has been sold to ESI.] The commercial version is an Edinburgh
standard prolog interpreter and compiler with several extensions, and
runs on Sun3, Sun4, HP9000 (Unix), RS/6000 (Unix), VAX (VMS), IBM PC
(MS-DOS, Windows 3.0/3.1), and 386s. The windows version includes BIPs
for programming windows graphics and dialogues.
Documentation is available as a 2-volume set published by Ablex (type
"prolog2" for info). ESL Prolog is also discussed extensively in Tony
Dodd's book "Prolog: A Logical Approach" from Oxford University Press.
