Editing MAD (programming language) (section)

== MAD, MAD/I, and GOM ==
Three MAD compilers exist:
# Original '''MAD''', the compiler developed in 1959 at the University of Michigan for the [[IBM 704]] and later the [[IBM 709]] and [[IBM 7090]] [[mainframe computer|mainframe]] computers running the [[University of Michigan Executive System]] (UMES) and the [[Compatible Time-Sharing System]] (CTSS) [[operating system]]s.<ref name=MADManual>[http://www.bitsavers.org/pdf/univOfMichigan/mad/L2-UOI-MAD1-2-RX_MADum_62.pdf ''A User's Reference Manual For The Michigan Algorithm Decoder (MAD) For the IBM 7090''], Digital Computer Laboratory, Graduate College, University of Illinois, 1962, 221 pages</ref><ref name="deepblue.lib.umich.edu">[http://deepblue.lib.umich.edu/bitstream/2027.42/3292/5/bab2545.0001.001.pdf ''The Michigan Algorithm Decoder (The MAD Manual)''], Bruce W. Arden, Revised Edition 1966</ref> In the mid-1960s MAD was ported at the [[University of Maryland]] to the [[UNIVAC 1108]].<ref name=UnisysMad>{{cite journal|url=https://wiki.cc.gatech.edu/folklore/index.php/UNIVAC_and_ALGOL#MAD|title=UNIVAC and ALGOL|author=George Gray|journal=Unisys History Newsletter|volume=6|issue=2|date=June 2002|archive-url=https://web.archive.org/web/20170629210750/https://wiki.cc.gatech.edu/folklore/index.php/UNIVAC_and_ALGOL|archive-date=June 29, 2017}}</ref> Versions of MAD were also available for the [[Philco]] 210-211 and [[UNIVAC 1107]].<ref name=UnisysMad/>
# '''MAD/I''', an "extended" version of MAD for the [[IBM System/360]] series of computers running under the [[Michigan Terminal System]] (MTS). Work on the new compiler started in 1965 as part of the [[Defense Advanced Research Projects Agency|ARPA]] sponsored CONCOMP project at the University of Michigan. As work progressed it gradually became clear that MAD/I was a new language independent of the original 7090 version of MAD.<ref name=MADIManual>[http://deepblue.lib.umich.edu/bitstream/2027.42/3709/5/abu9341.0001.001.pdf ''The MAD/I Manual''], Bolas, Springer, and Srodawa, CONCOMP Technical Report 32, 1970, University of Michigan, Ann Arbor, 194 pages</ref>
# '''GOM''' (Good Old MAD), a reimplementation of the original 7090 MAD for the [[IBM System/370]] series of mainframe computers running the [[Michigan Terminal System]] (MTS). GOM was created in the early 1980s by Don Boettner at the University of Michigan Computing Center.<ref>[http://hdl.handle.net/2027.42/79612 ''MTS Volume 2: Public File Descriptions''], University of Michigan Computing Center, 1990, p. 14</ref><ref name=GOMManual>[http://hdl.handle.net/2027.42/79620 ''GOM Manual''], Don Boettner, University of Michigan Computing Center, Ann Arbor, June 1989</ref>
