(*
Example code for loop/lend

NOTE - I'm thinking seriously about changing the syntax for this.

Loop/Lend is a simple way to repeat a block of instructions a number of times. It
does nothing you couldn't do with a repeat or while loop, but it doesn't require a
control variable.

Note that if the count for a loop is zero or negative it will be ignored, i.e. the
statements inside the loop won't be used even once.

So, here are a couple of examples.

; A simple loop that fills a block of memory with a pattern.
; (look at the code tab to see it)

		org 0					; Start at zero
	
		loop 32					; 32 * 8 = 256 bytes	
  		  db $00,$01,$02,$03,$04,$05,$06,$07	;
    		lend					;

; Now, two nested loops with a relative instruction inside, so the value changes.
	
		org $200		; Start at $200			

Fred		loop 8			; 8 outer loops
	          loop 2 		; 2 inner loops
		  jr Fred		; Something that changes
 		  lend			;
    		lend			;

; Now, same again but all on one line...

	loop 8:loop 2: jr Fred:lend:lend; Neurgh!

; I'm sure you get the idea.
