These notes have originally been developed for a course I taught at King’s College London in 19. That means that it documents the system, but it does not explain the basics of the Prolog language and it leaves many details of the syntax, semantics and built-in primitives undefined where SWI-Prolog follows the standards. the file name in brackets, but without the ending.

SWI-Prolog no longer limits the use of malloc() or uses assumptions on the addresses returned by this function. ISO Prolog implementations have the built-in predicate unify_with_occurs_check/2 for sound unification but are free to use unsound or even looping algorithms when unification is invoked otherwise, provided the algorithm works correctly for all cases that are "not subject to occurs-check" (NSTO). SWI-Prolog has been under continuous development since 198.
Although Logtalk cannot cope with everything proprietary in SWI-Prolog, specially when a mix of Prolog modules and term-expansion is used, it’s often able to compile Prolog modules as objects without changes. It is not yet good at recognising the relations between source code fragments and queries. prolog and (Google groups).

It does affect foreign code (see section 12) that uses the normal atom and compound term interface for manipulation lists. 1 Windows-specific Operating System Interaction. Alternatively, you can also load the program by passing its name as a parameter to SWI-Prolog: swipl -s program. The predicates format/1,2 and writef/2 provide formatted output. See the reference manual for deciding on whether to use the 32- or 64-bits version. These packages ara available for Linux and Windows and can be downloaded at swi-prolog homepage.
