I'll bet 99% of people -- even those who ran OS/360 -- didn't t know what Roll
out / Roll in did.
I found it included in Mitre OS/360 SYSGEN when I joined company in 1971,
laughed, exercised it, removed it -- saving xxKB from resident nucleus, back

Widening the perspective. Versatile IPCS is used to analyze all sorts of
dumps--SVC, standalone, SYSM--as well as GTF trace, which can be for hardware
or software or both. So why is it so little used outside of the 'system
programming' inner sanctum? At my one and only GUIDE conference in 1980,
Hope you are well Shmuel. We had one at NVIP. I believe my first performance
problem was related to slowness early on after the online came up. One of the
files ended up on MSS and the first time through was delayed by waiting for
back end staging to the 3350s, I believe we had 2 staging

That's a legitimate diagram, not the old OS.360 joke diagram.
