'''MDL''' (the MIT Design Language) is a descendant of the [[Lisp programming language|Lisp]] [[programming]] language. It allows user-defined data types and had some advanced I/O features. Its syntax distinguishes among executable lists, non-executable lists, strings, and arrays, and between global and local values of variables. Although MDL is obsolete, some of its features have been incorporated in later versions of Lisp.

MDL's claim to fame is that it was used to write the original version of the [[Zork]] [[computer game]].

MDL was originally named "Muddle", and was designed for the Dynamic Modeling Group at [[Massachusetts Institute of Technology|MIT]]'s [[Project MAC|Laboratory for Computer Science]] and implemented on the [[PDP-10]] computer under the [[Incompatible Timesharing System]].
