		Programming is done by extending the language with 'words' (the term used for Forth subroutines), which become part of the language once defined.
		Forth has been popular for developing embedded systems and instrument controls because it is easy to add small machine code definitions to the language and use those in an interactive high-level programming environment.
		Forth became very popular in the 1980s because it was well suited to the small microcomputers of that time: very efficient in its use of memory and easily implemented on a new machine.

	Forth programming language - Wikipedia, the free encyclopedia
		Forth is a procedural, stack-oriented, reflective programming language and programming environment.
		Forth became very popular in the 1980s because it was well suited to the small microcomputers of that time: very efficient in its use of memory and easily implemented on a new machine.
		Forth programming style uses very few named data objects compared with other languages; typically such data objects are used to contain data which is used by a number of words or tasks (in a multitasked implementation).

	Forth programming language : Forth (Site not responding. Last check: )
		Forth is a computer programming environment developed by Chuck Moore[?] then at the US National Radio Astronomy Observatory (NRAO[?]) during the 1960s, and later formalized as a programming language in 1977, and standardized by ANSI in 1994.
		Forth is usually implemented with an inner interpreter tracing indirectly threaded machine code, which yields extremely compact and fast high level code which can be compiled rapidly.

	Stack Computers: 3.3 OVERVIEW OF THE FORTH PROGRAMMING LANGUAGE
		This is because the primitives of the Forth language are defined at a very low level, and correspond to the machine code operations that would have to be present in any stack machine.
		The consensus among Forth programmers is that use of the Forth language reduces development time by a factor of 10 compared to other languages over a wide range of applications.
		Forth has not been used extensively in extremely large programming efforts, so its effectiveness in very large applications is as yet unknown.

		The forth programming language was originally formalized in the early 70s by Chuck Moore, but its beginnings predate that by several years, mostly as a small, specialized programming platform for various systems.
		Forth had a brief stint with popularity after microcomputers were introduced, often being the first language to support the new microprocessors, but soon fell into relative obscurity in mainstream programming.
		Forth is built upon the belief that every implementation aspect of the language should be as simple as possible, and that all complexity should be built upon this base of simplicity.

	WHAT IS FORTH
		Forth was invented by Charles Moore, a freelance programmer who had worked on control and data acquisition applications in environments ranging from a carpet factory to the Stanford Linear Accelerator Center.
		Nearly all Forth words use the parameter stack for both their arguments and their results; the return stack is used for flow of control within a program and (occasionally) for temporary storage of working values.
		The ANSI Forth Technical Committee (X3J14), which operated under the auspices of both CBEMA and the IEEE Computer Society, made slow but steady progress reconciling the existing Forth dialects, and the after many revisions the committee's work was finally approved as the American National Standard for Forth Programming Language in the Spring of 1994.

	BBC - h2g2 - Forth - the Programming Language
		Compiled languages - programs ran very quickly but took a long time to write, as each time a change was made, the program had to be recompiled, which could take five or ten minutes.
		Forth was 'flavour of the month' in the early 1980s, until people actually tried writing programs in it.
		The term 'Fourth Generation Language' (4GL) went on to mean something different in the computer world (a language for interrogation of relational databases), and Forth is not a 4GL in the normal sense of the term.

		Forth was created in 1970 by Charles H. Moore.
		Many larger machines had several languages to communicate between user and machine, such as an application, a complier, a supervisor, and an assembler.
		The program would be converted through these languages so it could communicate with the machine.

	One Definition of Forth
		Instead of seeing Forth as an approach to problem solving rather than a specification for a programming language there is now a formal ANSI specification for the Forth programming language.
		The 10% of the programs that are Forth can be optimized to be compact and efficient and may be more compact and efficient than other programs that also start with a 90% overhead.
		Forth has been most sucessful in the embedded programming arena where severe restrictions in computing power and memory size dictated by minimal cost and power consumption requirments demand compact and efficient programs.

	Forth - the LEGO of Programming Languages - 1995
		Unlike syntactic languages that require the use of a complex combination of syntactic structures to create an expression, Forth is a semantic language where the syntax is just words with spaces between them and the meaning is the defintion of the words.
		The simplicity is unmatched in any other programming langugage, and this is why Forth is usually the first language implemented on new machines, is the language that boots up on Sun workstations and new "Open Boot Firmware" bus machines, can fit in the ROM of common microcontrollers, and can be easily implemented directly in hardare.
		Forth is not as well known or widely used as 'C', more things are published in 'C', it is widely used in universities, and there are more jobs in 'C'.

	Forth Language
		In the 80s, Forth was also commonly used by astronomers (and their grad students!) to program the control systems of telescopes and other instruments.
		Forth is a low-level language when you start, because it doesn't come with a large vocabulary of ready-made words for every application.
		Not so much a negative criticism of forth (or lisp or scheme), but an observation that extensibility of a language tends to be used in very incremental ways, while those looking for radically new constructs tend to choose a different language entirely regardless of the expressive power of the macro suite.

		This concept isn't common in programming languages, but it has a name (in fact two names): "macros" (by which I mean LISP-style macros, not the lame C preprocessor) and "domain specific languages" (DSLs).
		Linux because instead of programming directly to the hardware on a bare PC which I could have done, I went for a simpler tutorial by assuming that the 'hardware' is a Linux process with a few basic system calls (read, write and exit and that's about all).
		In this FORTH you cannot easily turn a codeword pointer back into a dictionary entry pointer, but that is not true in most FORTH implementations where they store a back pointer in the definition (with an obvious memory/complexity cost).
