Pascal-P compiler. 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.

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.
