(MAD) An early programming language, based on ial, developed at the University of Michigan by R. Graham, Bruce Arden, and Bernard Galler in 1959.

MAD ran on the ibm 704, ibm 709, and ibm 7090, and was later ported to philco, univac and cdc computers. It was one of the first extensible languages: the user could define his own operators and data types.

mad/1 was a later version.
