Yeah, but did anybody evfer actually find a use for the MARK
instruction? The best I could do was to push MARK on the stack
and then remeber where I'd left it.
Not in the least bit surprising that MARK was the only user mode
instruction that wasn't needed in compatability mode (RSX-11M/M+
don't use it and thier compilers don't generate it).
