The Complete FORTH

Alan Winfield

In English
ISBN: 0-905104-22-6 (Fennica) (HelMet) (Kirjastot.fi) (Library of Congress)
Publisher: Sigma Press

FORTH is a new, unusual and exciting computer language. Originally developed to control telescopes, it has since been applied in many diverse fields including the animation sequences for 'Star Wars'.

FORTH is a compact and fast language: faster than BASIC yet more flexible. It is more than just a language: it is a programming language, editor, assembler and disk operating system all rolled into one. In short, a complete 'environment'. This book describes the standard dialect of FORTH, together with numerous examples, exercises and complete programs. Read it - you'll never use BASIC again.
