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. ------------------------------------------------------------------------------- - Nelson H.
