This _is_ documented, Al, old chum. In IM vol. IV. Where else would a
rank amateur like myself get such information? The reference to the
dirID=2 included the word "always" so I thought it sounded safe to use.
The information was somewhere in the introductory description of HFS, where
paths, etc., are discussed. Page IV-92, line 2. Still, the algorithm
presented earlier, which watched for errors instead, has the merit that
if Apple does not define "always" as I do, it will still work.

Thanks for the information, people!
