An application that I am working on needs to save information on a file so
that that file may be opened later.  What is the minimum amount of information
that is needed in order to get at a file?  So far, I have been storing the
file's name and volume reference number.  I call SetVol and everything
seems to work fine until I save this info, exit the program and restart.
The SetVol call then fails with a "Volume not found".  I know that under
HFS, there is a directory reference number floating around out there that I
may need to use, but I haven't had any success at playing around with these
either.

Any hints?

Pete O'Leary.
