I'm not sure if this is what you're looking for. I think there should be an END statement just above the Delay routine or a GOTO loop if you want to repeat the sequence.

Code:
	movwf	LEDPORT	
	call	Delay
	call	Delay	
	   bcf	    LEDPORTA0, LEDA0	                    ; RA0 off
             
             END  ; if you want to stop right here
             GOTO loop   ; if you want to repeat some section of code.  Ofcourse you have to 
                              ; put the label 'loop' where you want it.
