I was wondering if that would be a problem. For my situation, either of the
following would work:

  1. The last exit status that is set wins. So if there are multiple END
procs, and they all set the exit status (by calling #exit), the last one
registered wins (END procs are called in the order they are defined,
correct?)
  2. Calling #exit in an END proc does nothing, but calling #exit!
immediately terminates with the given status (skipping any remaining END
procs).

From my perspective either one of these will work; others may have a
preference and/or additional ideas.

Thanks,


Nathaniel
