PIP

[Peripheral Interchange Program]

vt.,obs. To copy; from the program PIP on CP/M, RSX-11, RSTS/E, 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').
