IMHO the original poster was looking for an atomic ada construct similar to
the 'continue' statement in C. We, including myself, responded with
'work-arounds' that achieved the same thing.

Some of us who write Ada for the US government are stuck with coding
standards which prohibit the use of 'goto' under any circumstance. Not good
CS, but we have to learn to live with it.

I don't know how to use the 'exit' statement to get out of a block.
Elucidate, dear doctor?

Yes, that's also what my psuedo code does.

Please lets not get into a 'which language is better' mode. I've been using
Ada for almost 15 years now, and C for longer. Both Ada and C/C++ have
there uses.
