; Program Initialization
;-----------------------------------------------------------
INIT:							; The initialization routine
		; Initialize Stack Pointer
								; Init the 2 stack pointer registers

		; Initialize LCD Display
								; An RCALL statement

		; Move strings from Program Memory to Data Memory
								; A while loop will go here

		; NOTE that there is no RET or RJMP from INIT, this is
		; because the next instruction executed is the first for
		; the main program

;-----------------------------------------------------------
; Main Program
;-----------------------------------------------------------
MAIN:							; The Main program
		; Display the strings on the LCD Display
								; An RCALL statement
		
		rjmp	MAIN			; jump back to main and create an infinite
								; while loop.  Generally, every main program is an
								; infinite while loop, never let the main program
								; just run off
