First best thing -- wrap DIVISION into a subroutine. If you look at the list output for something like

temp1 = temp2 / 10 

You will find a LOT of code is generated for division. In fact, if you are using division, multiplication or modulo anywhere in your application, wrap 'em into a subroutine and you will find huge amounts of code space freed up, e.g.

' Use -- result = MATH_DIV word|byte, word|byte
' when mixing word and byte, the WORD comes first...
' tmpW1 and 2 are word vars

FUNC MATH_DIV

   IF __PARAMCNT = 2 THEN
      tmpW1 = __PARAM1
      tmpW2 = __PARAM2
   ELSEIF __PARAMCNT = 3 THEN
      tmpW1 = __WPARAM12
      tmpW2 = __PARAM3
   ELSE
      tmpW1 = __WPARAM12
      tmpW2 = __WPARAM34
    ENDIF
    tmpW1 = tmpW1 / tmpW2     
    RETURN tmpW1

    ENDFUNC
