I really beleive that this can not be easily solved unless an array can be used greater than 16. I am becoming clueless of what else to try. 

I have moved the RA lines over to RB and have the following Interupt code:

' ---------------------------
INTERRUPT
' ---------------------------
ISR_Start:

RC = 0       'CLEAR DISPLAY OUT TO PREVENT GHOSTING
 ' Inc RA       'INCREMENT COLUM ADDRESS (RA I/O PINS)
Inc RB
 ' RC = NOT Display( RA )     'LOAD NEW ROW DATA TO RC
RC = NOT Display( RB )

IF RB > 15 then
RB = 0
EndIf

ISR_Exit:
RETURNINT 63
