Is there a description of the opcodes/bytecodes used in the p-code VM
anywhere?
I don't have one online. Really, there are several. P-code was
used in Wirth's early Pascal compilers, and it mutated with time
and improvements by others. UCSD made their own, but it too
changed with each major release.
As for Java, it may have inherited the concept but not the byte
values for its codes.
