Jonathan, thanks for the quick reply. I am aware of the LIST option on HLASM. Actually, I've added code to z390 to mimic its behaviour :-)
The point is, I do not have access to HLASM on real iron. So I was wondering whether or not the omission in the PoP had been repeated in HLASM. The proof of the pudding would have been to see the instruction being assembled correctly. I'll take your word for it, HLASM will assemble it just fine. Kind regards, Abe Kornelis ========== Op 29/03/2018 om 10:05 schreef Jonathan Scott: > Abe Kornelis writes: >> Anybody care to double-check on HLASM being aware of the WFKHEXBS mnemonic? > HLASM definitely supports this mnemonic.
