A high-level programming language. A major feature of Forth is that user- defined operators can be used as if they are primitives.

Forth is a high level programming language that works like RPN (Reverse Polish Notation) on a calculator. It differs from typical programming languages, like C and Fortran, because it is interactive.

language developed in 1970 by Moore. Forth is fairly portable and has versions on many different platforms. While it is no longer an very popular language, many of its ideas and concepts have been carried into other computer programs. In particular, some programs for doing heavy-duty mathematical and engineering work use Forth-like interfaces.

a compiled language

(n.) Originally, a “fourth-generation programming language” that was created by Charles Moore. Forth is considered an extensible and customizable language.

A niche programming language originally designed for real-time control of telescopes. An ANSI standard since 1994 (X3.215). Forth has a simple syntax and many keywords, unlike C/C++ and similar languages, which are the opposite. Forth programs are made up of many small procedures, and math is via RPN. These procedures are compiled, though Forth has no compiler in the traditional sense. Forth is essentially just a collection of procedures, called words, and an interpreter. Nowadays, Forth is used primarily to test and debug hardware and bring up systems. Only about 2% of the subscribers of Embedded Systems Programming reported using Forth regularly in a 2001 survey. Interestingly, some Unix workstations boot a small Forth interpreter before the rest of the operating system. One such environment is Sun's Open Boot, which provides Forth programming capabilities right out of ROM and a small bootloader that enables the operating system to be manually or automatically loaded and run from a disk drive or over a network. IEEE 1275 defines a standard based on Open Boot. [ more

Forth is a programming language and programming environment, initially developed by Charles H. Moore at the US National Radio Astronomy Observatory in the early 1970s. It was formalized in 1977 and standardized by ANSI in 1994.
