The definitive guide to this system is Pascal Implementation: The P4 Compiler and Interpreter by Steven Pemberton and Martin Daniels. It provides the complete, documented source code for both the compiler and interpreter.

Written in Pascal, this program translates Pascal source code into P-Code. PASCAL Implementation: P4 Compiler Compiler and...

By targeting an abstract "P-Machine," the compiler remains machine-independent. To port Pascal to a new system, one only needs to write a P-Code interpreter or a P-Code-to-native-code translator for that specific hardware. The definitive guide to this system is Pascal

Compile pcom.p and pint.p using an existing Pascal compiler. you follow these steps:

To use the P4 system for compiler implementation, you follow these steps:
