Extractions: Forth Programming Language Overview : Charles Moore created Forth in the 1960s and 1970s to give computers real-time control over astronomical equipment. A number of Forth's features (such as its interactive style) make it a useful language for AI programming, and devoted adherents have developed Forth-based expert systems and neural networks. Functions in Forth are called "words." The programmer uses Forth's built-in words to create new ones and store them in Forth's "dictionary." In a forth program, words pass information to one another by placing data onto (and removing data from) a "stack," a software structure in which the last element in is the first element out. Using a stack in this way (Forth's unique contribution to the world of programming languages) enables Forth applications to run quickly and efficiently. Two groups of loyalists (the Forth Interest Group and the Institute for Applied Forth Research) help promote the language. Two lively books by Brodie (1984, 1987) are perhaps the best-known introductions to Forth, and an article by Sperry (1991) is a short, well-informed overview. Townsend and Feucht (1968) discuss Forth in connection with expert systems. The San Jose-based Forth Interest Group lists a number of independent developers who have build Forths for various platforms.

Extractions: by Jeff Fox Preface Computers are amazing machines. They have an incredible potential. At their best they provide an extension to our minds and our traditional media assisting us in storing and retrieving data, making calculations and decisions, visualizing information, and communicating information between humans. At their worse they introduce nightmarish complexity and problems into our lives. They account for an entire industry that is vast and pervasive and which works in cooperation with strong media and socio-economic forces to sell and promote computer use in our culture. The technological fads and media hyped product feeding frenzies that we know of as the modern computer industry also have a dark side. The phenomenon known as the digital divide is the way that technology is creating a strong social economic division in our culture that could influence generations. Those with access to modern computers will have access to nearly unlimited information and a world of training, experience and opportunity that the have-nots will never know. The strong and disturbing evidence is that home computers, SAT test practice programs, and access to the internet have become prerequisites to enrollment in a good college and getting a good job in the future. Those without a way to get a foot up into the system will be forever kept out. One aspect of the digital divide is that computers themselves must be made to appear inconceivably complex and incomphrehensible to the uninitiated.

Extractions: History Significant Language Features Areas of Application Sample Programs ... Acknowledgments 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 created an interface between humans and machines. 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. But this took time to do, so Forth is more of a direct link between the user and the machine. Not an interpreted language, it is compiled. This increases speed.
Minimal Instruction Set Computers
Stackbased processors, 5-bit words, 25 instructions, 7000 transistors, 80 MIPS, 50 milliwatts, low cost; designed by Chuck Moore, creator of forth programming language.
http://www.ultratechnology.com/misc.html

Extractions: The term MISC refers to Minimal Instruction Set Computers in general, and to the chips designed by Chuck Moore at Computer Cowboys. These chips are unusual in many ways. They are designed on Chuck's VLSI CAD software called OKAD. They are implemented in CMOS Silicon VLSI processes and are very small and fast. They use a CPU architecture based on the Forth computer language, and with only five bit instructions. The first chip to be produced at Computer Cowboys was stands for Multi-Micro Processor. With only 25 instructions MuP21 is a Minimal Instruction Set Computer. But it is not just he instruction set that has been minimized, much of the complexity in modern chips is gone. MuP21 is implemented in only 7000 transistors vs millions of transistors on other modern chips. MuP21 includes not only a Forth Engine CPU, but also a memory interface processor, and a video output processor on the chip. With only 7000 CMOS transistors MuP21 can execute 80 million instructions per second and only draw 50 milliwatts of power. A paper entitled MuP21 a High Performance MISC Processor was published by Charles Moore and C.H. Ting in the January 1995 issue of Forth Dimensions.

The 'needs core-ext' at the top of the file is specific to Quartus Forth, and the MD5 definition at the bottom of the file calls a specific routine in the Palm OS; the rest of the file, however, is Standard Forth.

Extractions: Within a loop, even within IF-ELSE-THEN structures within the loop structure, you can place WHILE, CONTINUE, or BREAK statements. There is no limit as to how many, or in what combinations these instructions are used. A WHILE statement checks to see if the value on the stack is false. If it is, execution jumps to the first statement after the end of the loop. If the value was true, execution falls through to the statement after the WHILE. The CONTINUE statement forces execution to jump to the beginning of the loop, after the BEGIN. The BREAK statement forces execution to jump to the end of the loop, at the statement after the REPEAT or UNTIL, effectively exiting the loop.
