ALGOL 68S is a programming language designed as a subset of ALGOL 68, to allow compiling via a one-pass compiler.[1] It was mostly for numerical analysis.

Implementations

A compiler for ALGOL 68S was available for the PDP-11, written in the language BLISS. The multiprocessor version designed for the C.mmp[2] has been preserved at the PDP Unix Preservation Society archive.[3]

Charles H. Lindsey created another implementation of ALGOL 68, named ALGOL 68S, for Sun-3, Sun SPARC (under SunOS 4.1), Sun SPARC (under Solaris 2), Atari ST (under GEMDOS) and Acorn Archimedes (under RISC OS), c.f. Charles Lindsey's Home Page

Chief differences from ALGOL 68
