I am working on a utility where I need to be able to write to a directory
entry.  I am able to *read* from a directory file using FINDFIRST and
FINDNEXT ms-dos calls, but I can't find any way to write back to the
directory.  MS-DOS won't allow treating the directory like a file, so
it can not be opened for normal file operations.  (The CHMOD function
call won't allow changing the directory bit, which would have allowed
turning the directory entry into a file entry temporarily.)

I realize this can be done through writing directly to the disk sector
containing the directory entry, but the root directory lies at different spots
on floppies, and different hard disks, so this poses a compatability problem.

If anyone has any suggestions, I would be very thankful.
