MAD (programming language)
MAD (Michigan Algorithm Decoder) is a programming language and compiler for the IBM 704 and later the IBM 709, IBM 7090, IBM 7040, UNIVAC 1107, UNIVAC 1108, Philco 210-211, and eventually IBM System/370 mainframe computers. Developed in 1959 at the University of Michigan by Bernard Galler, Bruce Arden and Robert M. Graham, MAD is a variant of the ALGOL language. It was widely used to teach programming at colleges and universities during the 1960s and played a minor role in the development of Compatible Time-Sharing System (CTSS), Multics, and the Michigan Terminal System computer operating systems. The original version of the chatbot ELIZA was written in MAD-SLIP.
The archives at the Bentley Historical Library of the University of Michigan contain reference materials on the development of MAD and MAD/I, including three linear feet of printouts with hand-written notations and original printed manuals.
Three MAD compilers exist:
While MAD was motivated by ALGOL 58, it does not resemble ALGOL 58 in any significant way.
Programs written in MAD included MAIL, RUNOFF, one of the first text processing systems, and several other utilities all under Compatible Time-Sharing System (CTSS). Work was done on a design for a MAD compiler for Multics, but it was never implemented.
The following is an interesting quote from An Interview with Brian Kernighan when he was asked "What hooked you on programming?":
MAD was quite fast compared to some of the other compilers of its day. Because a number of people were interested in using the FORTRAN language and yet wanted to obtain the speed of the MAD compiler, a system called MADTRAN (written in MAD) was developed. MADTRAN was simply a translator from FORTRAN to MAD, which then produced machine code. MADTRAN was distributed through SHARE.
MAD/I has a syntactic structure similar to ALGOL 60 together with important features from the original MAD and from PL/I. MAD/I was designed as an extensible language. It was available for use under MTS and provided many new ideas which made their way into other languages, but MAD/I compilations were slow and MAD/I never extended itself into widespread use when compared to the original 7090 MAD.
