I'm surprised nobody else has commented that we saw this about 3
months ago. Tom Van Vleck wrote about CTSS:
Louis wrote a disk loaded program called RUNCOM that
read command
lines from a file, substituted arguments into the command, and
requested the supervisor to run them, and then return control to
RUNCOM. This is a shell-like function.
...
Revised command processing, RUNCOM, and . SAVED are documented in
the second edition CTSS manual.

Our assumption at the time was that the "rc" comes from this program.
