Here's my version of led52, which doesn't work. The device is changed to SX52, and all the obsolete DEVICE directives are removed. I've changed the whole port C to be outputs so I can use any of its bits. What else is needed? 

[code]
;-------------------------- DEVICE DIRECTIVES --------------------------

		DEVICE		SX52,OSC1MHZ

IFDEF	__SASM  ;SASM Directive
		IRC_CAL		IRC_SLOW
		
ELSE		;Parallax Assember Directives
		
ENDIF

		RESET		Initialize

;------------------------------ VARIABLES ------------------------------
			
		Count1	EQU	$08
		Count2	EQU	$09

;---------------------------- DEBUG SETTINGS ---------------------------

		FREQ 	1_000_000
	
		WATCH	Count1,16,UDEC

;------------------------ INITIALIZATION ROUTINE -----------------------

Initialize
		;Configure port settings
		mov	rc, #%00000000		;Port C output zero
		mov	!rc,#%00000000		;Port C output dir.

;---------------------------- MAIN PROGRAM -----------------------------

Main
;Toggle RC with a delay of 64k counts in-between.

		call	delay			;delay	
		mov	W,/RC			;toggle all of RC port
		mov	RC,W				
		jmp	Main			;goto main				


Delay		clr	Count1  		;Initialize Count1, Count2	
		clr	Count2								

Loop		djnz	Count1,loop		;Decrement until all are zero		
		djnz	Count2,loop							
		ret				;then return				
[/code]
