So to david nugent do I speak these words:

Yep, TP it is...

Actually, it's C++ I'm using... I keep forgetting the minor (no comment on
that please! :-) ) differences from one version to the next.

It's just that most of my interesting ASM routines are designed for
interfacing with TP. And it seems much simpler then the C equivelents...
Expecialy at times when you don't need the extra length!
