When I first started at my current employer in 1983,
there were a scattering of mainframe (3270) terminals, all
of which presented a short list of login options. One of
these was TSO; that's what I had an account for and
was supposed to be using. But one of the other choices
was IMS [1]. One day, curiosity got the better of me and
I selected that. Anyone who has used IMS probably knows
what happened next: Big blank screen. I tried everything I
could think of to get out of there: "quit", "exit", "bye",
"logoff", "logout" -- nothing worked.  Even power cycling
the terminal of course does nothing on a 3270. Panicing at
that point, I sheepishly called the mainframe help desk,
and was told -- of course in a BOFH-ish tone of voice --
that the way you get out of there is with the "/RCL" command.
As with <ctrl-x><ctrl-c> in emacs, this was the only
command I ever learned in IMS.
