MOVF STORE1,STOREV
MOVF STOREV,W
XORLW 0X21 if same with w register Z=1
BTFSC STATUS,Z
CALL DIO ;DIO !
is this routine will trigger if register storev contain 0x21 to subroutine DIO,
Can anyone can tell me how to test an 8bit wide data USING PIC when btfss and btfsc are available

If you look on the PICList there's on entire section on 8bit and 16bit comparisons and checks.

I cut and pasted it from the site - and clicked on it just now, it's working fine.

We talked about your code already, the MOVF function creates a copy and does not delete the original. I see you ignored everything I said...
