PIP
/pip/ [Peripheral Interchange Program] vt.,obs. To copy;
from the program PIP on CP/M, RSX-11, RSTS/E, TOPS-10, and OS/8
(derived from a utility on the PDP-6) that was used for file
copying (and in OS/8 and RT-11 for just about every other file
operation you might want to do). It is said that when the program
was originated, during the development of the PDP-6 in 1963, it was
called ATLATL (`Anything, Lord, to Anything, Lord'; this played on
the Nahuatl word `atlatl' for a spear-thrower, with connotations
of utility and primitivity that were no doubt quite intentional).
