New machine language port

[Joe Horn]

Aha... I think I detect the problem here. Are you trying to use those mnemonics in System RPL mode, outside of a CODE / ENDCODE block? If so, that's the problem. None of the mnemonics you listed are System RPL commands. They are Saturn assembly language mnemonics which only makes sense inside the source code of a Code object. In brief, System RPL is a different language than Saturn Assembly Language. You *can* create a single System RPL program object which contains both SRPL code and Saturn code, but to do that you must enclose all Saturn code inside a CODE / ENDCODE bloack in the System RPL source code.

If the above does not describe your problem, then please post the shortest source code you've had trouble with, and share exactly how you tried to assemble it, and exactly what the result was. That would help us figure out what's causing the errors you're seeing.
