This book will guide you through the process of porting a Forth interpreter
to a SUBLEQ machine. If you can port a Forth interpreter to the SUBLEQ target,
you can port a Forth interpreter to any machine.
Any one with an interest of in Forth, and with an interest of how a Forth
interpreter and system actually works should buy this book. Included is
commentary about the design decisions necessary to get a Forth system
working, so you will learn both how and why.
The book will also help in those learning about how machine code is generated,
and touches a little about how compilers work and how operating systems work,
but only those that are similar to microcomputers of the 1980s.
