That's very true. I was just trying to show what could be done
with regard to jumping out of a block where an exception has
occured.
In any case, like I said in my post, I don't recommed this way of
approaching the problem. In fact, I actually regret making
that post because, every time I have seen an Ada program with a
"goto", I have always been able to find a better way to write the
program; so I suppose that I really should not be gently encouraging
people to use "goto".
Most others seem to have an experience similar to mine: "goto" means
you need to change your approach. So I was wondering, has anyone out
there ever encountered a situation where "goto" was actually necessary?
