Well, opening the file gets you the reference number, so that part's
easy. Now we just have to figure out how to open it.

The idea that immediately occurs to me is to get the application's
resource fork refNum by calling CurResFile() at the start of your
application. Next, find the location and name of the resource file by
calling GetFCBInfo().  That will give you the vRefNum, dirID, and file
name that you need to call HOpen().
