Retro Pascal Compiler Memory Optimization: Clever Tokenization Techniques

2025-03-20

This article delves into the memory optimization strategies of a retro Pascal compiler. To accommodate limited memory, the compiler employs tokenization, converting error messages, reserved words, identifiers, and other elements into bytecodes. The article provides detailed hexadecimal representations and meanings of error codes, source tokens, and P-codes (pseudo-machine codes), revealing how the compiler efficiently handles the compilation process through clever tokenization and bytecode manipulation. This is valuable reading for those studying compiler design, reverse engineering, and embedded systems programming.
