P-code
A
p-code is similar to a
byte-code but a p-code works at a higher level. Whereas byte-codes work at a very low level similar to
machine code, p-codes can perform moderately complex tasks such as printing a message or clearing the screen. Some implimentations of
BASIC and
Pascal use p-codes generated by a
just-in-time compiler.
The Business Operating System (BOS) of the 1980s was a cross-platform operating system designed to exclusively run p-code based programs.
