The Zork Implementation Language (ZIL) is a domain-specific programming language for creating text-based adventure games, also known as interactive fiction. It was developed by Infocom in the late 1970s and was used to write many classic titles like Zork, Enchanter, and Planetfall. The language uses an object-oriented design with hierarchically organized objects and inheritance. Programmers use a toolset that includes a compiler named ZILCH to translate source code into virtual machine instructions understood by Infocom's game interpreter called the Z-machine. Despite being largely superseded today by modern game development tools, there remains an enthusiast community dedicated to preserving and enhancing these vintage games written in ZIL through open-source interpreters such as Frotz that can run on various platforms from PCs to mobile devices.
