Peripheral Interchange Program
The Peripheral Interchange Program (PIP), on the Digital Equipment Corporation's DEC-10 and PDP-11 computers was a utility to transfer data files. After some use, it was finally realized that the hand-crafted syntax
PIP destination:origin
actually was inverted from common English usage. Thus the
COPY from to
syntax was born, one of the dozens of utilities that resided on the PDP and DEC machines. As late as the mid 1970s, PIP was in common use, along-side its descendant. After Gary Kildall started CP/M, he took the PIP and file concepts as well. The protean utilities which move data can also be seen in the UNIX
cp from to
which also ran on the Teletype workstations of the early 1970s and which survive in MS-DOS.
