Nope. None of the two.
'BEGIN' has a special meaning in awk patterns. It means "run this block
of code before you start reading any input records".
If you 'exit' somewhere in a code block, then awk will terminate the
script after the first line that matches the relevant pattern. This is
probably not quite what you want when awk filters through a long list of
words.
