FORTH on the BBC microcomputer

*About this book* Forth on the BBC Microcomputer and Acorn Electron serves as a general introduction to FORTH, and includes a full description of Acornsoft FORTH with a glossary defining the actions of all standard words.

Acornsoft FORTH is a complete implementation of the FORTH language to the 1979 Standard specification for the BBC Microcomputer Model B and Acorn Electron. In addition to a comprehensive set of arithmetic and stack operators, control transfer words and defining words, Acornsoft FORTH includes full graphics commands and the more advanced features for defining the actions of defining words themselves. This opens the door to Meta-FORTH, and user-defined FORTH-based languages.

The Acornsoft FORTH system includes the FORTH Assembler, Editor, and graphics demonstration.
