  A Brief Introduction to Forth
At a deeper level, Forth programs use RPN not as an end in itself, but rather as a means to achieve simple syntax and flexible modularity.
This example follows the Forth convention of including a stack-effect comment showing that a (the second stack element) and b (the top stack element) are consumed as stack inputs, with c produced as the stack output.

  Forth - Wikipedia, the free encyclopedia
Forth is still used today in many embedded systems (small computerized devices) because of its portability, efficient memory use, short development time, and fast execution speed.
Forth is a simple yet extensible language; its modularity and extensibility permit the writing of high-level applications such as CAD systems.
Forth relies heavily on explicit use of a data stack and reverse Polish notation (RPN or postfix notation), commonly used in calculators from Hewlett-Packard.

 FORTH, Inc. -- Evolution of Forth
FORTH was spelled in upper case until the late 70's because of the prevalence of upper-case-only I/O devices.
By knowing exactly how Forth would use these resources, by omitting hooks and generalities, and by sheer skill and experience (he speculated that most multiply/divide subroutines were written by someone who had never done one before and never would again), his versions were invariably smaller and faster, usually significantly so.
Forth was designed for a programmer who was intelligent, highly skilled and professional; it was intended to empower, not constrain.

 Forth programming language - overview
Forth is not an assembler, it is a high-level language (although most versions also include an assembler for the target processor).
Forth is characterized by an interactive programming style, which dramatically shortens development times, and by extremely small target program size.
Forth was developed in the early 1970s at the National Radio Astronomy Observatory, where it was used for radio telescope control, on-line data acquisition, and data analysis.

 comp.lang.forth FAQ: General Information (1 of 7)
FORTH was spelled in upper case until the late 70's because of the prevalence of of upper-case-only I/O devices.
In the beginning Forth systems were native and performed the functions of an OS (from talking to hardware to multi-user multi-tasking).
And if the purpose is to show off Forth (e.g., by having smaller code size), there are easier projects for that, the compatibility requirement eliminates some of the potential advantages, and not that many people care about the code size of an OS kernel enough to be impressed.

 The Evolution of Forth
Forth had been born and bred to exploit the minimal facilities of resource-constrained systems.
By publishing assembler listings, the Forth Interest Group was able to encapsulate a Forth run-time environment in a manner that could be easily replicated and/or translated to the assembly language of a different computer architecture.

 Forth - the LEGO of Programming Languages - 1995

With Forth at work I could write code to test a new device, run it, and show the results to the engineer who built it about as fast as he could describe what it was suppose to do.

 Forth Language
ChuckMoore: The inventor of Forth, ColorForth, and ForthProcessor?
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.

 Forth - TunesWiki
A Forth program, after parsing, is nothing but a list of words, executed consecutively by the "inner interpreter", the core of Forth.
Forth is fully reflective and self-containing; the Forth parser (the so-called "outer interpreter") is written in Forth and can be modified at any time.
More generally, Forth is a very low-level language, with manual management of memory, fixed-size buffers, pointer manipulation; but reflection makes it a remarkably powerful language among low-level languages.

 Moving Forth: Part 3
This differs from the usual Forth interpretation process in that the address of the word-to-execute is given on the stack, and not taken from the "thread" (as pointed to by IP).
When the Forth interpreter encounters DEUX -- that is, when the Forth IP is at IP(1) -- it does the usual thing: it fetches the address contained in DEUX's Code Field, and jumps to that address.
When the Forth IP is at IP(1), the Forth interpreter jumps to the Code Field of DEUX (and increments IP).
