CORC was designed with ease of use in mind. In contrast to the BASIC programming language under contemporaneous development at Dartmouth College, it used English language statements. Since programs were tediously input with punch cards, the compiler had a high tolerance for error, attempting to bypass or even correct problem sections of code. Students could submit a program by 5 PM which would be compiled or run overnight, with results available the next morning.
It was initially run on the Burroughs 220 and later extended to the Control Data Corporation CDC 1604. In 1966 it was superseded by CUPL, a batch compiler for teaching which ran on the IBM System/360.
An extension of CORC, the Cornell List Processor (CLP), was a list processing language used for simulation.
