Winfield Alan. The complete Forth

Sigma Tecnical Press, 1983. — 131 p. — ISBN: 0-905104-22-6.How best to read this book
Like any new programming language FORTH must be learned from the ground floor up. There may be quite a few floors in the FORTH building, but the effort is exceedingly worthwhile, as I hope I showed earlier in this introduction!
Nevertheless, FORTH is an interactive language, meaning that programs may be developed and tested 'at the keyboard', or, what is more useful at this stage, FORTH may be learned 'at the keyboard' as well. This means that as each new facility is explored we may actually try out the facility on a microcomputer running FORTH, and that is true right from the very beginning!
This book is an ideal accompaniment to a brand new FORTH system running on i xyour microcomputer, but don't worry if you do not have a microcomputer to hand, the examples will make sense anyway. Virtually all of the FORTH which appears throughout the text may be typed in, and accepted by most of the standard FORTH systems currently available. If your system conforms to the FORTH-79 standard (produced by the FORTH Standards Team), then all of the examples will run without modification. If not, you may have to consult the documentation for your system, to identify any differences.
