<p><span class="h1">Retro: a Modern, Pragmatic Forth</span>
<br/><br/>
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.
<br/><br/>
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.
<br/><br/>
But it's not a traditional Forth. Retro draws influences from
many sources and takes a unique approach to the language.
<br/><br/>
Retro has a large vocabulary of words. Keeping a copy of the
Glossary on hand is highly recommended as you learn to use Retro.
<br/><br/>
This book will hopefully help you develop a better understanding
of Retro and how it works.
