Access pin using index

[skimask]

That's not nice but it works

This may not be any nicer, and I'm not even sure if it'll work...but...

temp var byte
pin var byte

pin = 0 : temp = porta     'initial pin to zero and save porta to temp
loop: pin = pin + 1 : if (temp.0[pin] <> 0) AND (pin <> 4) then loop
got_pin:    'when you get here, if pin = 5 then porta.0 thru porta.3 <> 0
