Sure, you could do something like this to convert two bytes to four hex digits: UNPK OUT(3),IN(2) MVC OUT+3(1),IN+1 OI OUT+2,X'F0' OI OUT+3,X'F0' TR OUT(4),TRTABLE-240 Or you can do: UNPK OUT(5),IN(3) TR OUT(4),TRTABLE-240 IN DS XL2 OUT DS CL5 TRTABLE DC C'0123456789ABCDEF' I would opt for the latter. -- Tom Marchant
