One that I exploited heavily was the "ON ENDPAGE" trap: I wrote code
that we used from both PL/I and Fortran to attach running page
headers/footers, with a job name, timestamp, and page number. This
mattered to us a lot when our nightly outputs sometimes ran to a box
of z-fold paper (1K or 2K sheet? my memory is hazy).
In Unix, of course, we would just run
myprog | pr > myprog.lst
but IBM mainframes of the 1960s and 1970s did not have anything
remotely like that at academic customer sites.
Alas, all of my PL/I code archives were lost to a dumpster some 30
years ago: we lacked the disk space to make copies of a couple of
thousand 9-track tapes, and with the retirement of our DEC mainframes,
we no longer had 9-track tape drives to read the tapes. I have long
regretted our action, but budgets, and the limited technology of the
time, gave us no option.
