So that settles it, Ada definitely precedes M2, since the first public specification (preliminary Ada) is 1979. Note that this is the right level to compare with the public "specification" of M2. If you want to compare final ISO standard dates, then of course Ada also precedes M2. Going over some notes, and discussions, it is clear to me that my recollection is accurate, there was no very specific input from M2 to Ada, the timing as shown from the above was just wrong. However, of course, M2 and Ada are related in the sense of being Algol-like languages developed at the same time in the same mix of ideas. Probably the threads of input are a bit different. For example, it is clearly the case that Algol-68 had a significantly greater influence on Ada than on M2 (considering the history this is not surprising :-) -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
