That guy that invented Pascal, Nick Worth(sp), would disagree. He points to
the situation where you have nested levels of 'if' statements, say 10
levels,
and you have to 'get out' because of an error. Without the 'goto' you would
have
to handle this by having more or more complicated 'else' statements. The
'break label' handles this case nicely.
