32 bit counter
I use the following assembly routine whenever I need a 16 bit counter
infsnz var
incf var + 1
but now I need a 32 bit counter (in assembly).
Apparently, I'm not smart enough to figure it out for myself.
Can someone please show me how to implement my 32 bit counter?

almost the same, but you'll need Var+2 and var +3
Maybe some stuff could be extracted from

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

It appears that the best routine would be
count32
incfsz var
bra doneproc
incfsz var + 1
bra doneproc
incfsz var + 2
bra doneproc
incf var + 3
bnc doneproc
bsf eflag,0
doneproc
but I can't test it tonight. Can anyone find anything wrong with this?

This has to work... hey that was easier than you thought right?
EDIT it runs smooth on MPSIM...well for that i may trust MPSIM

I tried it this morning. It works. The technique works with any number of bits.
