If the question were limited to...

  EXIT 'label'
vs.
  EXIT [number of levels]

It seems obvious to me that a label is much to be preferred to a count.


However, in both cases you are no longer strictly structured.  I would
say that EXIT when used to leave the innermost loop is structured.

SKIP (I find myself liking this better than NEXT or CONTINUE) to skip
to the end for another iteration is also structured IMHO.

If you have fallthru in a case structure EXIT to the end of the cases
is structured as well, although fallthru itself isn't.  I don't object
to it either way.  I believe fallthru adds a burden on the programmer
that isn't needed.

I would prefer that EXIT did one predictable thing only.  But that's just me.
