The T3X/0 language discussed in the book is simple and has its roots in Pascal and BCPL. The book assumes some prior knowledge of procedural programming languages like C or Pascal, as well as assembly language for the Z80 CPU and the basics of the CP/M operating system. However, it also includes a short introduction to Z80 assembly language for determined self-learners. The book leaves no stone unturned and explores various aspects of compiler construction, including lexical analysis, syntax analysis, code generation, simple optimizations, the BDOS interface, and the runtime library.
