forth - Computer Definition
(FOuRTH-generation language) A high-level programming language created by Charles Moore in the late 1960s as a way of providing direct control of the computer. Its syntax resembles LISP, it uses reverse polish notation for calculations, and it is noted for its extensibility. It is both compiler and interpreter.
