Designed to be compact, learnable, and easy to adapt to specific needs, it has been developed and refined through continual use by a small community over more than a decade. Forth is a stack based programming language created in the late 1960's by Chuck Moore. Over the intervening decades it has evolved through use, with many dialects along the way.
