Is it GUPI? I understand that IBM had intended that it not be GUPI.
However it leaked into the lore in pre-OCO times.
STARTIO existed long before the notions of GUPI, PSPI and DMTI. AFAIK,
IECDIOSB became classified DMTI long after the fact: as of MVS V5 I
believe. Before that it was in the logic manuals, microfiche, etc. and
still appears in the source-maintained portions of products like JES3
and IMS.
