'''Amiga E''' is a [[programming language]] created by Wouter van Oortmerssen on the [[Amiga]] computer. The work on the language started in 1991 and was first released in 1993. The original incarnation of Amiga E was being developed until 1997, when the popularity of the Amiga platform dropped significantly after the bankruptcy of Amiga intellectual property owner [[Escom AG]].<ref>{{Cite web |title=1994-1998: From Commodore-Amiga to ESCOM to Gateway |url=https://sites.google.com/site/amigadocuments/ |access-date=2023-01-11 |website=Amiga Documents |language=en-US}}</ref><ref>{{Cite web |last=van Oortmerssen |first=Wouter |date=1999-11-04 |title=Statement of the future of Amiga E |url=http://www.ecs.soton.ac.uk/~wvo96r/e/efuture.txt |url-status=dead |archive-url=https://web.archive.org/web/19991104065743/http://www.ecs.soton.ac.uk/~wvo96r/e/efuture.txt |archive-date=1999-11-04 |access-date=2023-01-12 }}</ref>
According to Wouter van Oortmerssen:<blockquote>"It is a general-purpose programming language, and the Amiga implementation is specifically targeted at programming system applications.

== Overview ==
Amiga E combines features from several languages but follows the original [[C (programming language)|C programming language]] most closely in terms of basic concepts. Amiga E's main benefits are fast compilation (allowing it to be used in place of a [[scripting language]]), very readable [[source code]], flexible [[type system]], powerful [[module system]], [[exception handling]] (not [[C++]] variant), and [[Object-oriented programming]].<ref name=":0" />
Amiga E was used to create the core of the popular Amiga graphics software [[Photogenics]].<ref>{{Cite news |date=1995-12-01 |title=Amiga E 3.1i, Cover Disk 122 |pages=10 |work=CU Amiga Magazine |url=https://archive.org/details/cuamiga-magazine-070/page/n9/mode/2up |access-date=2023-01-16 |archive-url=https://archive.org/details/cuamiga-magazine-070/page/n9/mode/2up?q=%22amiga+e%22 |archive-date=2012-09-20}}</ref>
== "Hello, World!" example ==
A [["Hello, World!" program]] in Amiga E looks like this:
{{pre|
PROC main()
WriteF('Hello, World!')
ENDPROC
}}
