better coding methods to freeing active ram in small pics

[longpole001]

interesting - had code that was compiling to 2001 words , code had a large section of select case with 24 case options ( buttons ) , replacing them with if then , compiled to 1978 words , does not look as nice but heck worth the saving in program space

When I have bits using them as bit variables or flags, I set them as this:

my_flag    var byte
  flag1      var my_flag.0
  flag2      var my_flag.1

etc

Also recently Darrel gave a tip for a calculation.

IF ABS(x-y)>16 THEN...

Using this:

IF X>Y THEN
    Z=X-Y
ELSE
   Z=Y-X
ENDIF

which compiles about the half size.

So, a little common sense and experimenting is all that is needed.
