Arity/Prolog

Description

A Prolog development system initially supplied in 1985 for DOS with a version for 16 bit OS/2 following a few years after, these 16 bit systems were sold on a modular basis, you could start out by buying an interpreter, then add a compiler, SQL Sever and so on. The initial version shipped for 32 bit OS/2 was a new development of the compiler and interpreter and not fully compatible with the older Arity/Prolog version 6 for 16 bit DOS and OS/2.
