Hi Bill12780,
Take a look at this post and see if it helps.

I think this is what you are looking for. In the manual under "Ports and other Registers".

anyvar = PORTB & $0f   'Isolate lower 4 bits of PORTB and place result into anyvar

$0f = 00001111
$00ff = 11111111

Now you can check "anyvar" for changes.

Thanks everyone...

These are some really good idea's. I had to "walk away" for awhile. I will read Melanie's post(man she is a wealth of knowledge....Bet she was born with a PBP manual in her hand!), try a few things. and get back with you all tonight.

Thanks for the tips.

This will work;

X VAR BYTE

main:
  for X = 0 to 7
      if PortB.0[X] = 1 then xxxxx
  next X
  goto main

PortB.0 <-- zero after PortB indicates you're dealing with a bit.

PortB.0[X] <-- [X] = the bit index pointer.

"PortB.0 <-- zero after PortB indicates you're dealing with a bit.

PortB.0[X] <-- [X] = the bit index pointer."


Thanks bruce that is a brilliant little tidbit of information (for a noob like me)that I probly glazed over in the manual 20 times and it never stuck..

Thanks! I knew it could be done like that...Just not smart enought to figure out how! hahha

thanks again!
