Welcome to Retro, my personal take on the Forth language. This is a modern system primarily targeting desktop, mobile, and servers, though it can also be used on some larger (ARM, MIPS32) embedded systems.

The language is Forth. It is untyped, uses a stack to pass data between functions called words, and a dictionary which tracks the word names and data structures.

But it's not a traditional Forth. Retro draws influences from many sources and takes a unique approach to the language.

Retro has a large vocabulary of words. Keeping a copy of the Glossary on hand is highly recommended as you learn to use Retro.

This book will hopefully help you develop a better understanding of Retro and how it works.
