Hmm, do you think that=92s a big enough reason to use Microchip C18 =
instead of
HI-TECH's compiler? I have no yet used PIC's enough to know how often =
you
would need to use a 24 bit variable, and if you could juse use asm in =
those
cases you do.

I only noticed HI-TECH PICC lacked 24 bit support when I wanted to =
implement
Roman Black's one-second timer which needed a 24 bit variable. I guess =
in
this case I could have used a 32 bit variable, but used inline assembly
instead.

Frequently. There are many cases where 16 bits isn't quite enough but 32 =

Probably less of an issue on the PIC18, but on the 16 series, RAM is =
usually
the first thing you run out of.
