Editing Genera (operating system) (section)

== Programming languages ==
Symbolics provided several [[programming language]]s for use with Genera:

* [[ZetaLisp]], the Symbolics version of Lisp Machine Lisp
* [[Common Lisp]] in several versions: Symbolics Common Lisp, Future Common Lisp (ANSI Common Lisp), CLtL1
* Symbolics Pascal, a version of [[Pascal (programming language)|Pascal]] written in Lisp (Lisp source is included in Genera distribution)
* Symbolics C, a version of [[C (programming language)|C]] written in Lisp (Lisp source is included in Genera distribution)
* Symbolics Fortran, a version of [[Fortran]] written in Lisp (Lisp source is included in Genera distribution)

Symbolics Common Lisp provides most of the Common Lisp standard with very many<!-- Someone quantify this, please. --> extensions, many of them coming from ZetaLisp.

=== Other languages from Symbolics ===
* Symbolics [[Prolog]], a version of Prolog written and integrated in Lisp
* Symbolics [[Ada (programming language)|Ada]], a version of Ada written in Lisp

It is remarkable that these programming language implementations inherited some of the dynamic features of the Lisp system (like garbage collection and checked access to data) and supported incremental software development.

Third-party developers provided more programming languages, such as [[OPS5]], and development tools, such as the [[Knowledge Engineering Environment]] (KEE) from IntelliCorp).
