Save some bytes in program memory

[pedja089]

You can save some code space if you use multiple If condition instead one with multiple AND.
Example:

IF portb.0 AND portb.1 AND portb.2 AND portb.3 THEN
ENDIF '46words

But if you break that in multiple if's

IF portb.0 THEN
 IF portb.1 THEN
  IF portb.2 THEN
   IF portb.3 then
   ENDIF
  ENDIF
 ENDIF
ENDIF

Code is just 13 words.
