Hi All.

I was squeezing some folks assembler code today and ran across
part of it when one needs to compare variable against several
constants one by one and if case is equivalency found jump to
some address.

What I originally had :

	movfw	var

	xorlw	A	;first compare vs A constant
	skpnz
	goto	addr_its_equal

	xorlw	B^A	;then compare vs B constant
	skpnz
	goto	addr_its_equal

	xorlw	C^B	;then compare vs C constant
	skpnz
	goto	addr_its_equal

etc...

Interesting squeeze was found :) so I decided to share
in case if somebody else might find idea helpful.

	movfw	var
	xorlw	A
	skpz
	xorlw	B^A
	skpz
	xorlw	C^B
	skpnz		;
	goto	addr_its_equal
