77. The RTVMM of claim 1 wherein an O-OPL byte-code loader is used to load an HLL byte-code program into a computer system, the implementing step comprises the step: causing each byte code to be examined when a class is loaded to determine whether it operates on pointer or non-pointer data; causing pointers to be pushed onto and popped from a pointer stack; causing non-pointers to bc pushed onto and popped from a non-pointer stack.
