The Forth Programming Language Forth Name: Forth Created: By: Charles H. Moore Home Page: Acronym: none Language type: interpreted stack-based language Extensions: .4th .frt .muf Tutorial: Note: An extensible programming language that uses data stacks and tokens, and has a postfix syntax. Forth was created in 1970 by Charles H. Moore. He wanted to create a language that would allow more direct user and machine interaction. Therefore he created Forth. He designed the language on an IBM 1130, which he considered a third generation machine. But he considered his language a fourth generation language. Because of this he decided to name the language "Fourth," but unfortunately the IBM 1130 only allowed five character file names so it got shortened to "Forth." Forth has one of the simplest syntaxes of any computer language. The syntax can be stated as: Forth code is a bunch of words with spaces between them. Each word is equivalent to a function or subroutine in a language like C. Functions are executed in the order they appear in the code. The following statement is an example that could appear in a Forth program: WAKE.UP EAT.BREAKFAST WORK EAT.DINNER PLAY SLEEP. The dots between WAKE and UP and the other words simply connect the two words to make one. Forth word names can have any combination of letters, numbers or punctuation.

It features both interactive execution of commands (making it suitable as a shell for systems that lack a more formal operating system ), as well as the ability to compile sequences of commands into threaded code for later execution. Its name is derived from Mr. Moore's belief that it was a " fourth-generation computer language " on a computer whose file system allowed only five-letter identifiers Forth offers a stand-alone programming environment, consisting of a stack oriented interactive incremental interpreter compiler . Programming is done by extending the language with 'words' (the term used for forth subroutines ), which become part of the language once defined. 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.

Table of Contents Background Recommended Software The Stack The Compiler ... Data Types Some background information on Forth Forth is simply the greatest computer language I've ever seen. My first language was BASIC on old IBM PC's and Apple ]['s. From there, I moved up to Pascal, then C. I tried to use object-oriented languages like C++ and Java, but I hated them. I even started to write my own language, but it was too heavily influenced by C. I gave up that project when I found Forth. It's simple, elegant, fast, powerful, extensible, and practical. Forth was developed by Chuck Moore, starting way back when he was in college in the late 1950's. In 1970, he named it Forth. Around that time, other people started to find out about it, and they were deeply impressed at how simple and powerful it was. You could write a program in Forth faster than you could in other languages of that time, like Algol and Fortran, and it would run faster and take up less of your precious memory. In the three decades since then, Forth has been used mainly by scientists, the military, and big industries, for everything from tiny single-board microcontrollers to giant networked databases. Meanwhile, mainstream computing has continued its stuffy academic tradition. Today's typical computer is bogged down with all the layers of bureaucracy that existed in the 70's, and then some. Windows NT 4.0 occupies hundreds of megabytes of disk space, and 40 megs of RAM, leaving hardly anything for programs even on high-end machines! Linux is better, but still big, especially if you use X-windows. By contrast, a complete Forth-based operating system (with a graphical interface and everything) fits on a single floppy disk.

66. Levels Of Code In Forth Programing Levels of code in forth programming. The ANS forth programming Language specification IS a formal specification for a programming language. http://www.ultratechnology.com/levels.htm

Levels of code in Forth programming I had been programming in Fortran and assembler for a number of years when I got my first personal computer. It was exciting. On the first generation PC one had to toggle in a paper tape loader from front panel switches, byte by byte, then start the paper tape reader and then one could output to the led on the front panel. I had waited for the first model that booted from ROM, had a parallel port for keyboard input and had video output from he factory, it was 1974. The PC I got had a wonderful monitor program that replaced a front panel with a nice video display of the contents of all the CPU registers where one could change anything and single-step through programs seeing everything visualized before you. One could also the video for text and graphics display by your programs. I found it very educational. About a year later I upgraded from 1KB of RAM to 9KB and could now run an assembler or BASIC interpreter/editor on the 8080. There was DOS but I could not afford a disk and used cassette storage. I also found FIG-FORTH about that time. Since I had assembler training I found that Forth let me do everything I could in assembler and much more and do it much faster and re-use my old code that I had compiled and added to the dictionary in my-language.

Forth from a programmer's perspective Forth relies heavily on explicit use of the stack data structure and Reverse Polish Notation (or RPN, also used on advanced calculators from Hewlett-Packard ). This notation is also called postfix notation because the operator comes after its operands, as opposed to the more common infix notation where the operator comes between its operands. The rationale for postfix notation is that it is closer to the machine language the computer will eventually use, and should therefore be faster to execute. For example, one could get the result of a mathematical expression this way: This command line first puts the numbers 25 and 10 on the implied stack; the "*" command multiplies the two numbers on the top of the stack and replaces them with their product; then the number 50 is placed on the stack, and the "+" command adds it to the previous product; finally, the "." command prints the result to the user's terminal. Even the language's structural features are stack-based. For example:

70. FORTH forth programming. A section of programming using FORTH, rather than discussing FORTH itself. There are duplications of some sites http://www.cs.wisc.edu/~bolo/forth.html

FORTH Forth is a stack-oriented language and interactive environment. It is versatile, light weight, and highly adaptable. Forth was originally created by Charles Moore in the late sixties. The name is an allusion to Forth being a "fourth" generation language. In some ways it is, in others not. Forth is probably a transition between 3rd and 4th generation languages in that it allows you to CREATE a language which is suited for your task. For many years (late 1980s, early 1990s), it seemed that Forth was dying out. The number of Forth programmers had declined. The number of hardware limited platforms which forth excels at utilizing efficiently also declined. Managers would say it isn't mainstream and not allow the use for Forth even it was THE tool for the job. However Forth has become resurgent. In 1994 a new standard for Forth was published by ANSI. This new standard, though it does cause problems for many people who use Forth to its true potential, does open up the market for a standard which all vendors can provide compatability to. In addition, I believe the standards body made some fine analyses of things which widely differed between forth systems and managed to Factor them into more basic parts which actually eliminate many existing difficulties.

Marshall Space Flight Center, Alabama Forth Source Code Analysis Tool Set (FSCATS) is a computer program that provides a wide range of capabilities for documenting, analyzing, and reverse-engineering computer programs written in the Forth programming language. FSCATS also aids in the management of software, estimating costs of software, and development of metrics for characterizing software. The functions performed by FSCATS include the following: Categorizing lines of code and counting the lines in each category; Producing cross-references for all words, constants, and variables; Producing cross-references for all definitions; Identifying unused and multiplicate definitions; Identifying unused and undefined Forth words; Identifying development system code, missing library definitions, and missing compiler definitions; and Listing a call tree at selectable levels of detail Selected categories of symbols (partial structure) Only application-code-type symbols (classical structure chart).
