You have to use SPARK Ada. I could be wrong, but I was under the impression that the SPARK subset disallowed exceptions entirely because they are too difficult to analyze. If so, the only exceptions that might occur in a SPARK program are the predefined ones; and as I understand it the SPARK tool set gives you a way to prove, under certain circumstances, that even those will not occur. Not being a heavy SPARK user, however, I could be off base here. Peter
