I found the English documentation for the prolog on the Houston File server. The program is from the "TOY" project and is a reduced implimentation of PROLOG10. The book and the original source are: Prolog for Programmers by F.Kluz'niak and S Szapkowicz Published by Academic Press, 1985, 400 pages - ISBN # 0-12-41620-6
