Study the complete source code for a self-hosting compiler that runs on and generates code for CP/M on the Z80 processor. No prior knowledge in the field of compiler construction is required. The T3X/0 language that is discussed and implemented in the book has its roots in Pascal and BCPL and is very simple. A full 20-page manual is contained in the book.

The reader should know at least one procedural programming language, such as C or Pascal, and at least one assembly language, ideally the one for the Z80 CPU. They should also know the basics of the CP/M operating system. For the determined autodicact a short introduction to Z80 assembly language is also included in the book.
