I don't know the answer, but I've found that the Goto works just fine. The
only problem is for organizations that don't allow Gotos.

Having spent a lot of effort to get this to work, I can assure that there
is no such limitation in Ada 83 or in Ada 95. In Ada 95, particularly, it
is messy because of finalization and exception issues. In any case, the
rule is that you can't Exit out of a body, but a block statement isn't a
body. (And I'd hate to be wrong here, because I use this occasionally, as
I like to use blocks to limit the scope of temporary variables.)
