MDL (programming language)

MDL (originally Muddle; MIT Design Language) is a LISP-like programming language introduced at MIT. It is best known for its use in Interactive Fiction as the original development language of Zork; later Infocom games used a language called ZIL that had a syntax based on MDL, though it didn't have the functional-language capabilities of its parent language.
