Didn't I just post that selfsame code yesterday, albeit in 8080?

How about:

	and	al,0fh
	xlate	hextable

hextable	 db	'0123456789ABCDEF'

Straightforward and fewer instructions.   Not only that, you can use ANY
character code (say, EBCDIC) for output.

Or even:

	and	al,0fh
	movzx	ebx,al
	mov	al,hextable[ebx]
