Whether you are a beginner seeking information on this multi-faceted programming language or a serious programmer already using FORTH, this book is a reference that should not be overlooked. The text describes FORTH syntax, specifically applicable to both FORTH-79 and FIG-FORTH. Included are notes on logical extensions and alternatives to the standard FORTH syntax. Hogan explains the history and uses of FORTH and provides a tightly structured synthesis of material from programming manuals, independent programmers, and the publications of the FORTH Interest Group. Many of his observations come from his own extensive use of FORTH in a major software project.
