Re: MI400 Digest, Vol 8, Issue 5

retired ::  you ask a question (and if i look) [developed a MI xlator OPM] which could reconstruct the subject program from the code  .. though i dont trace what IBM has done in recent releases i do have some understanding ... will review your e-mail
OPM is well known  .. perhaps not documented
