You can get the vRefNum from the global variable SFSaveDisk ($214, word).
Note, however, that this is a true vRefNum (actually, it's the negative
of a true vRefNum), and not a WDRefNum. To get the folder that the file
is in, you have to check another global variable, CurDirStore ($398, long),
which contains the current DirID. See the assembly language note on page
IM-72 of Inside Mac for more information.

No problem.
