"high table land," 1759, from Spanish mesa "plateau," literally "table," from Latin mensa "table" (source of Rumanian masa, Old French moise "table").
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.
