Thank you Chris, that is what I meant...  Well, it was just an idea, so
what can I say.  I knew from the beginning that it would be difficult to
make them on the chips etc.  And the protocol, would be large, and take
up a lot of The calcs mem w/in the shell.  But, just another one of
those crazy ideas floating around in my head...
