Scott asks: > > Does anyone have an idea as to what the MPE acronym stands for? Reliability, safety, stability, power and...the answer you wanted... Multi-Programming Executive Note: the exact capitalization/spacing/hyphentation may be in dispute... I couldn't find a copy of "Beyond RISC!", the (ahem) authority :) but an MPE-IV Intrinsics Manual defined it as "Multiprogramming executive (MPE-IV)" [sic]. and the System Error Messages manual of the same era capitalized the "Executive". -- Stan Sieler [log in to unmask] http://www.allegro.com/sieler.html
