This paper describes the architecture and instruction set of a machine to support PASCAL. This so-called P-code machine is designed both to be emulated on microprogrammable computers, and to be an intermediate step in code generation for traditional computers. Furthermore, an interpreter on CDC 6400 and a microprogrammed version of P-code on a minicomputer system are described. A percise description of all P-code instructions and examples of PASCAL programs with generated P-code are shown in appendices.
