Hi, Walter!

I've tried to use UD2 instruction (I want to generate exception to dump
registers), but got an error:
"Assembler opcode expected".

Opcode for UD2 is  '0F 0B' according to
Intel Architecture Software Developer's Manual Volume 2: Instruction Set
Reference (Order Number 243191)

It would be nice, if you implemented all instructions up to PPro (or may be
up to PIII) in inline assemler.

                  Looking f orward for your answer,

There are actually two of those opcodes,
    db  0fh,00bh
    db  0fh,0b9h
You can insert whichever one you want with the db pseudo-op.
