In years gone by, I had checkpoint/restart in COBOL programs
using Tape, so that they could pick back up from the last
checkpoint. Obviously a long running program since it was
processing multiple tapes (reel to reel stuff).
In the COBOL 6.2 Programming guide, there is chapter 36 that is
about Interrupts and checkpoint/restart, and that is found about
p. 651 (SC27-8714-01).
In the JCL REF, there is info on SYSCHK DD, and RESTART (JOB
stmt) that is associated.
I've not used these for many years.
But they are documented and are possibly still in use in certain
customer sites.
If IBM gets rid of this, they may have a loud cry from Banks
and/or TELCOs and others that have a short period of time to
process all their monthly data.
Granted, paperless statements have solved many of these old
problems, but still...

The Smart/Restart product uses it and runs COBOL applications.
