Examples will. For example, it has recently been quoted here the case of Meteor (parisian metro), in use since 1998, and whose software is still in version 1.0: no problem discovered in 12 years of usage. I also remember an example from a SIGAda conference (no reference at hand, does someone remember?) about a system in a Boeing airplane, which was doubly written in C and Ada for reasons of diversification. The C system had several major upgrades, while the Ada one worked flawlessly. -- --------------------------------------------------------- J-P.
