Cohen) writes: Just a few reasons that spring to mind quickly: Very impressive list Norman ! Perhaps it could be maintained in the FAQ ? A few more good reasons for considering Ada : - Ada has a generic contract model: the implementor and the user are isolated by the compiler, each dealing with his own errors. Some C++ compilers generate error messages stemming from templates or instances when the program is *linked*. - Classical C(++)-errors that aren't trapped at compile or run time simply have no Ada equivalent. Just a few that I'm familiar with : if (a=0) oops_meant_equality; while (b /= a) oops_meant_inequality; switch (a) { case 1: one; case 2: oops_forgot_the_break; (I have the impression that the rate at which I get bitten by these doesn't decline over the years, mostly because I'm getting spoiled by Ada between occasional C usage, but still I think this is an issue). -- Stef VAN VLIERBERGHE Eurocontrol - Central Flow Management Unit stef@cfmu.eurocontrol.be Avenue des Arts 19H Tel: +32 2 729 33 42 B-1040 BRUSSELS Fax: +32 2 729 32 16 Belgium
