Yeah that would work quite a lot of the code seems to be something like

	ldy	#something
loop:
	lda	(indirect),y
	;; do something with a here !
	iny
	bne	loop


So I guess that would become

	ldy	(indirect)
	ldb	#something
loop:
	lda	b,y
	incb
	bne	loop


That would work well I think.

Thanks.

Phill.
