Yes indeed: PIP was the most important CP/M command -- used for almost anything in the days that unix hadn't been invented
yet (actually I'm not totally shure of that) and that on-line meant remote TTY access to PDP6's. You're right: it shows my age :)=Oh, yes, UNIX was around in the days on CP/M (the earliest beginnings were, if the memory servers, in 1969, and the first semi-commercial version (text-processing on PDP-11 by Interactive Systems, RIP) in 1977). However, PIP is even older. I met it first in DEC's RT-11, but it might be even more ancient.
And just imagine, there are people here even older than myself
