Mesa
     
        Xerox PARC, 1977.  System and application programming for
        proprietary hardware: Alto, Dolphin, Dorado and Dandelion.
        Pascal-like syntax, ALGOL68-like semantics.  An early version
        was weakly typed.  Mesa's modules with separately compilable
        definition and implementation parts directly led to Wirth's
        design for Modula.  Threads, coroutines (fork/join),
        exceptions, and monitors.  Type checking may be disabled.
        Mesa was used internally by Xerox to develop ViewPoint, the
        Xerox Star, MDE, and the controller of a high-end copier.  It
        was released to a few universitites in 1985.  Succeeded by
        Cedar.
