Forth is unique among programming languages in that its development and proliferation has been a grass roots effort unsupported by any major corporate or academic sponsors. Originally conceived and developed by a single individual, its later development has progressed under two significant influences professional programmers who developed tools to solve application problems and then commercialized them, and the interests of hobbyists concerned with free distribution of Forth. These influences have produced a language markedly different from traditional programming languages. Presented at the ACM SIGPLAN History of Programming Languages Conference HOPL II, April, 1.

During his development of Forth, she became the second ever Forth programmer. Since then, she has become a leading expert in the language and one of its main proponents. Elizabeth was the chair of the ANSI Technical Committee that produced the ANSI Standard for Forth 1. She is an author of several books on Forth and gave many training seminars on its usage. Donald R. Colburn. Don Colburn was one of the earliest Forth users. He was one of the founders of the Forth Interest Group, and contributed to the development of the first public domain fig. Forth. Subsequently, he founded Creative Solutions, Inc. CSI, which introduced Mac. Forth in 1. 98. 4. Mac.

Forth based chip RTX2. NASA. At Computer Cowboys, Mr. Moore designed the Sh Boom microprocessor and then co founded i. Tv, an Internet Appliance manufacturer. During the 1. 99. CAD software to design several custom VLSI chips, including the F2. More recently, he invented color. Forth and ported his VLSI design tools to it. Moore served as CTO for Intella. Sys during development of the S4. Chuck Moores Programming Language. Early Development. Moores programming career began in the late 1. Smithsonian Astrophysical Observatory with programs to compute ephemerides, orbital elements, satellite station positions, etc. Moore, 1. 95. 8, Veis, 1. His source code filled two card trays. To minimize recompiling this large program, he developed a simple interpreter to read cards controlling the program. This enabled him to compose different equations for several satellites without recompiling. This interpreter featured several commands and concepts that survived into modern Forth, principally a command to read words separated by spaces and one to convert numbers from external to internal form, plus an IF ELSE construct. He found free form input to be both more efficient smaller and faster code and reliable than the more common Fortran practice of formatting into specific columns, which had resulted in numerous re runs due to mis aligned columns. In 1. 96. 1, Moore received his BA in Physics from MIT and entered graduate school at Stanford. He also took a part time programming position at the Stanford Linear Accelerator SLAC, writing code to optimize beam steering for the then pending two mile electron accelerator, using an extension of some of his prior work with least squares fitting. A key outgrowth of this work was a program called CURVE, coded in Algol 1. To control this program, he used an enhanced version of his interpreter, extended to manage a push down stack for parameter passing, variables with the ability to explicitly fetch and store values, arithmetic and comparison operators, and the ability to define and interpret procedures. In 1. 96. 5, he moved to New York City to become a free lance programmer. Working in Fortran, Algol, Jovial, PLI and various assemblers, he continued to use his interpreter as much as possible, literally carrying around his card deck and recoding it as necessary. Minicomputers appeared in the late 6. Moore added operators to manage character input and output. One project involved writing a Fortran Algol translator and file editing utilities. This reinforced for him the value of spaces between words, which were not required in Fortran source. Newly married and seeking a small town environment, Moore joined Mohasco Industries in Amsterdam, NY, in 1. Here he developed computer graphics programs for an IBM 1. This computer had a 1. CPU, 8k RAM, his first disk, keyboard, printer, card readerpunch used as disk backup, and Fortran compiler. He added a cross assembler to his program to generate code for the 2. This system could draw animated 3 D images, at a time when IBMs software for that configuration drew only static 2 D images. For fun, he also wrote a version of Spacewar, an early video game, and converted his Algol Chess program into the new language, now for the first time called FORTH. He was impressed by how much simpler it became. The name FORTH was intended to suggest software for the fourth next generation computers, which Moore saw as being characterized by distributed small computers. The operating system he used at the time restricted file names to five characters, so the U was discarded. FORTH was spelled in upper case until the late 1. IO devices. The usage Forth was generally adopted when lower case became widely available, because the word was not an acronym. Moore found the Forth based 1. Fortran environment in which the 1. This added looping commands, the concept of keeping source in 1. Forth today. Most important, there was now a dictionary. Procedures now had names, and the interpreter searched a linked list of names for a match. Names were compiled with a count and three characters, a practice learned from the compiler writers of Stanford and which prevailed in Forth until the 1. Within a dictionary entry was a code field containing the address of code to be executed for that routine. This was an indirect threaded code implementation see Section 5. Dewars paper on indirect threaded coded appeared in Communications of the ACM Dewar 1. The use of indirect threaded code was an important innovation, since an indirect jump was the only overhead once a word had been found. Dictionary entries could consist either of pointers to other high level routines or of machine instructions. Finally, in order to provide a simple mechanism for nesting routines, a second stack called the return stack was added. The benefit of having a stack reserved for return addresses was that the other stack could be used freely for parameter passing, without having to be balanced before and after calls. The first paper on Forth was written at Mohasco Moore, 1.
