Normally, it is redundant. I don't think there's any
possibility for an
exit to fail, but I
don't have Stevens handy at the moment, so I cannot
check. Of course, if there's any posibility the
msg subroutine gets redefined, it's not
redundant.
While I would be hesitant to put a call to exit
in a subroutine (but I have done it in the past), I certainly
wouldn't be eagar to remove the 'redundant' last.
It gives a clue that after finding key, the array isn't
searched any further.
