Summary

A faithful implementation of the ancient CUPL and CORC languages.

CUPL was an early (1966) teaching language implemented as a batch compiler on the IBM/360 at Cornell University. It was descended from an earlier (1962) experimental language called CORC (CORnell Compiler), which was in turn derived loosely from Algol-58. This project implements both.
