*sigh*

then just follow that stuff above with:

	ld	hl,start
	ld	bc,768
loop
	ld	(hl),0
	inc	hl
	dec	bc
	jp	NZ,loop


how hard can it be? think some.. please...

or take it in the same loop:

	ld	hl,start
	ld	bc,768
	ld	de,moveto
loop
	ld	A,(HL)		;load data
	ld	(hl),0		;erase
	ld	(DE),A		;put it at the new place..
	inc	hl
	inc	de		;increase pointers
	dec	bc		;decrease loopcounter..
	jp	NZ,loop
