Definitely 31bit. See the IRXSHVB data area mapping (used by the REXX variables access interface).

I'm asking because many moons ago I tried to use some REXX variables coming from RMM and due to large number of tape volumes (~25000) the script did not work. I asked on IBM-MAIN and people here explained it is because of 24-bit memory limitation. I vaguely remember it could be OS/390 2.10 -- Radoslaw Skorupka Lodz, Poland W dniu 29.06.2024 o 07:52, Rob Scott pisze: > I have been using REXX for over 30 years and I pretty much agree with > everything Dave says here. > > Having Python " automatically there " on a customer system will make it used > much more frequently by IBM, ISV and public domain software. > > REXX has always had some big pluses : > > 1.
