Thanks, I thought I had to be missing something. I stopped reading
the manual when it got past near and far defines in variables and on to bit
and sfr functions with pointers being just after that of course :-) .
As to the code I'm porting some from Keil and some of it is as you
note poor quality :-). Once (or in some cases as) I get it to compile I'll
try cleaning it up a bit.
