ZPL

ZPL is a high-level programming language developed by Z-Systems. It was designed for use in the Z-Machine, a virtual machine used by Infocom for its interactive fiction games. ZPL is based on the programming language Forth and shares many of its features, including a stack-based design and a simple syntax. However, ZPL also includes features specifically designed for use in interactive fiction, such as a text windowing system and support for multimedia. ZPL is a compiled language, and programs written in ZPL are typically distributed as Z-Code files. These files can be run on any system that supports the Z-Machine, including modern computers and mobile devices. ZPL is a powerful language that allows for the creation of sophisticated interactive fiction games. However, it is also easy to learn and use, making it a good choice for beginners. If you're interested in creating your own interactive fiction, ZPL is a great place to start.
