- An Introduction to Forth
This introduction isn't meant to be an all-inclusive tutorial about Forth, just a simple introduction for users of our near-infrared camera software which uses Mitch Bradley's CFORTH.Forth is a high level programming language which operates similarly to an RPN (Reverse Polish Notation or postfix) calculator. It differs from typical programming languages like C and Fortran because it is an interactive language. If you are using Forth, you do not need to recompile your program to add some new functionality. You can easily define a new command and it will instantly be available for you to use.
- Forth: An underview
This document is intended to give an informal overview of the Forth programming system and perhaps more importantly, the method and philosophy of programming in Forth. It illustrates the language's history, most prominent features, usage, etc.The language "Forth" was developed during the sixties while Moore was working as a computer programmer at the Stanford Linear Accelerator Center, and later as a freelance engineer. The object in developing this new "programming tool" was to overcome the need for an engineer to learn a large number of methods for controlling compilers (linkers, assemblers and directives plus high-level languages).
is Simple Forth
Forth is, among other things, a programming language whose ideals are freedom and simplicity. Freedom requires knowledge and responsibility, and simplicity is yet more demanding. But "simple" can also mean rudimentary. Simple Forth attempts to teach the rudiments of Forth.Forth is inherently interactive. Programming in Forth is carried on as a dialog between you and a machine that understands Forth. You send the machine some code. Depending on the circumstances, the machine responds by trying either to perform ("execute") or to remember ("compile") the code. If the machine then says something like "ok", that's good.

There are many ways to provide an introduction to any subject and FORTH is no exception. Skinner and Holland developed a system based on operand behavior. Their techniques have been successfully applied to many subjects.
Another scheme is to develop a careful step by step approach. Take one step at a time and build slowly. Always provide review of material and connection from one step to the next.
Alas, that is not the way we learned to do most things. That is not the way we learned to talk or think. Rather, we were exposed to many different areas of knowledge through experience from our early pre-school days. Bit by bit we took a little here and a little there and added it to our organization of what we already knew.
