Intermediate code is generated directly as the source code is parsed. At the end of Part II, the reader will be a very serviceable interpreter that supports user-defined functions, built-in functions, string, and list support together with a range of looping constructs. A simple console application is provided to allow users to exercise the interpreter.

The book provides fully working open-source code (also deposited at Github) and explains in plain English how the code works and why certain decisions were made. The book makes liberal use of code throughout the book chapters. Everything is done without the
