help clean up some code

[longpole001]

thanks mike , both option work ok , as it turned out i decided to go with "and" option , it just really large array group and as such it has about 30 " and " statements per match group of the records it takes about 10k compile for that section , large arrays do take space , i need to write the sorting index routine for this large array in PBP next , not seen any examples where using large data arrays to sort as yet

cheers

Hi,
Generally, using nested IF/THENs produces less code than using AND. For example

IF A = 1 THEN
  IF B = 2 THEN
    IF C = 3 THEN
      IF D = 4 THEN
          IF E = 5 THEN
            HIGH PortB.0
          ENDIF
      ENDIF
    ENDIF
  ENDIF
ENDIF

Compiled for a 16F628 is 30 words and 76 bytes for 18F4520 (all variables are bytes) while using AND, like this

IF (A = 1) AND (B = 2) AND (C = 3) AND (D = 4) AND (E = 5) THEN
  HIGH PortB.0
ENDIF

takes 79 words for the 16F628 and 162 bytes for the 18F4520.
