Except of course that that wouldn't work since it is nested under a second loop.
This is the only alternative to using a flag on the lines of the alternative
code.

People, listen closely, GOTOs are not inherently bad.  If used carefully
as in this example they are quite reasonable and really not hard to follow.
Of course, they would be much harder to understand if they didn't use
mnemonics and instead used numbers ala Pascal or ForTran.
