Abstract This paper describes the implementation of a P‐CODE interpreter by microprogramming. An existing system based upon the Pascal P compiler was modified by rewriting the interpreter in microcode. Consequent improvements in the system performance are illustrated by times for compiling the compiler and various small Pascal programs. The execution rate for the new system is also compared with several other languages available on the Eclipse. Problems relating to Eclipse microcode when used for tasks of this type are also discussed.
