  Yes it does put it in 'a' but it also puts it in 'de' or 'e' for
what we need.  This program will return.  So I guess the call uses the
acculator to load it into e at the last (should probably take look at
the memory with calcem).

loop:
 	ld a, 20	; \
 	call _setxxop1	; |--- This is the equivalent to _getk
 	call _op1toop2	; /
 	xor a		;Notice that I make a=0
 	call _op2toop1
 	call _convop1
	cp	22  ; Take out this and it will return
	ret	z   ;  ''   ''   ''   ''
	ld	a, e ; Take out this and it won't
 	cp 20    ;   ''     ''    ''    '''
 	ret z    ;   ''     '''   ' '   ' ' ' ' '''''''
 	jp loop
