If you write string code assuming Ada83 rules, it will behave accordingly. It's maybe more of an issue that some things which might have been considered a "mistake" in Ada83 are O.K. in Ada95 >Unless you are learning this for an existing, non migrating project, >give your educators a big kick, and tell them to teach Ada95. > Good advice. Ada95, having the GNAT compiler available, ought to be standard-issue for college courses in Ada. And given the new features, it ought to extend nicely from an "intro" level course on to advanced courses in operating systems, realtime systems, compiler theory, etc. >There is so much more that is better in Ada95. > >Dale > Yeah, verrily.
