Assembly language for a hypothetical stack machine, the

P-machine, said to have been an imitation of the instruction

set for the Burroughs Large System. The term was first used

in Algorithms + Data Structures = Programs, N. Wirth, P-H

1976. Byte articles on writing a Pascal Compiler in Northstar

BASIC (ca Aug 1978) also used the term. Later used in Apple

Pascal, and as the intermediate language in the UCSD P-system.
