ZIL (Zork Implementation Language) is a programming language (based on MDL, a programming language created at MIT which is based on LISP) used to develop interactive fiction games. It was developed by Infocom. It compiles into Z-code via the intermediary code ZAP (via a compiler that's apparently lost; however, see ZILF below for a new working compiler).

Interest in this language for new development has been spurred by the release in April 2019 of a large collection of Infocom source code.
