ANSI (typically pronounced as an acronym "ann-see") is the American National Standards Institute, a large engineering standards organisation with headquarters in Washington D.C and web site ansi.org. It was founded in 1918.
It is responsible for a number of important standards in computing, including:
- ANSI Standard C, usually called ANSI C, published as X3.159-1989.
- ANSI Standard Fortran, usually called Fortran 66, published as ASA X3.9-1966.
- ANSI Standard Cobol standards in 1968, 1974, and 1985.
- Expansion of 7-bit ASCII character set beginning in 1963.
As well as many other general engineering standards with application to historical computers:
- The threads of inch-based machine screws including UNC (coarse) and UNF (fine), used in very many US-designed computers.
