[TUHS] Fwd: Origins and life of the pg pager

All, I just received this e-mail from a non-TUHS list member. If you have an answer for Michael, could you reply to him and pop a cc here as well?

The research I've done so far vaguely suggests it came with one of the System V versions, though Internet claims it to be “the name of the historical utility on BSD UNIX systems” occasionally.[1] I think System V because the source code of pg.c in the util-linux package says that this utility is “a clone of the System V CRT paging utility.”[2] I'd also like to find out when pg was discarded and if it ever made it into POSIX before that. Linux still has pg to the very day, but none of the current major BSDs (Free/Net/Open) offer it. POSIX 2001, 2004 Edition lists it as an excluded utility.[3] I've not been able to get the text of any prior POSIX documents. It seems they aren't freely available. Any ideas on how to proceed? Best Michael [1] This one's from Wikipedia (https://en.wikipedia.org/wiki/Pg_(Unix)) but I've also found other sites stating the same.
