SICStus Prolog

Multi-platform industrial strength Prolog interpreter and toolkit. v2 and v3 versions of the toolkit were available on a number of platforms including OS/2 but from version 4 and onwards only released on Windows, Linux, Solaris and Mac OS X. v1 and v2 and possibly early versions of v3 also featured a built in Prolog compiler but it was eliminated from later versions as the performance advantages of the compiler versus the interpreter were not as great as they had been in early versions.
