That was for Ada '83 about 5 or 6 years ago. I know that we use as a code inspection checklist item that exceptions are not to be used for normal control flow. We do HRT. At "outside world" input interfaces, values are checked with normal logic comparisons and a completely deterministic response is given (often very helpful since the offending parameter is found in a very localized fashion). Could this be done in a more blanket fashion by enabling full Ada checks and having a local exception handler? Perhaps, but IMHO a system that is running properly _should_ not have any exceptions being raised. _____________________________________________________________________ Robert S.
