The term ''autocoder'' needs to be distinguished from ''[[autocode]]'', a term of the same era which was used in the [[UK]] for languages of a higher level. Both terms derive from the phrase ''[[automatic programming|automatic coding]]'', which referred generally to programs which eased the burden of producing the numeric [[machine language]] codes of programs.<ref>Hopper 1955.</ref> ("Autocoding" is seen occasionally, and can refer to any kind of programming system.) In some circles "autocoder" could be used in a rather generic way to refer to what is now called a macro-assembler.<ref>For an example see Allen 1981, p. 540.</ref>
The first Autocoders were released in 1955 for the [[IBM 702]] and in 1956 for the almost compatible [[IBM 705]].<ref>{{cite manual
The first Autocoders were released in 1955 for the [[IBM 702]] and in 1956 for the almost compatible [[IBM 705]]. They were designed by Roy Goldfinger who earlier had worked on [[New York University]]'s (NYU) NYAP assembler.<ref>Goldfinger 1956.</ref><ref>[http://hopl.murdoch.edu.au/showlanguage.prx?exp=2989 The Encyclopedia of Computer Languages<!-- Bot generated title -->] {{webarchive |url=https://web.archive.org/web/20070916104501/http://hopl.murdoch.edu.au/showlanguage.prx?exp=2989 |date=September 16, 2007 }}</ref> These machines were [[variable word length (computer hardware)|variable word length]] commercial machines, as were many of the computers for which an Autocoder was released.▼
