What readers say
about the 3rd edition
*

"Your succinct and clear organization — 'Just the facts ma'am' — is incredibly useful for someone who has a programming skillset, just not in Forth. Each and every one of my questions about memory organization, file management, strings and the like has been answered."

—Jeff Byron

"It's a great book. I enjoyed and profited from reading it cover to cover. At the same time, it will serve well by providing easy access to those tidbits of language and programming information you need, when you need them."

—Daniel B. Wright

Every serious Forth programmer — and everyone who wants to be one — needs this Forth book! Forth Programmer's Handbook goes far beyond the popular introductory text Starting Forth. It provides the detail needed to truly master this powerful language. Forth Programmer's Handbook is for programmers and engineers using ANS Forth systems such as SwiftForth™ for writing Windows apps and SwiftX™ for developing embedded systems.

The Handbook is intended for readers with a programming background but not necessarily prior experience with Forth. Offering comprehensive coverage of all major aspects of the Forth language — from basic principles to advanced concepts — the Handbook has become the de facto Forth reference manual for Forth programmers everywhere. This edition covers nearly 400 ANS Forth words and common extensions.*
