Forth
This article is about the programming language Forth in connection to Commodore computer systems.
Forth is a stack-based, extensible language without type-checking initially developed from Charles H. Moore in 1969. It is probably best known for its "reverse Polish" (postfix) arithmetic notation, familiar to users of Hewlett-Packard calculators[1]. Forth is a real-time programming language originally developed to control telescopes. [2]. Forth is also a programming language and develope system, which is stand-alone from an operating system.
