  Hi Kevin.  I'm the weirdo who found this problem.  Despite the name above,
I'm using a friend's account since I don't have one here.  My name is Charles
West, and I met you at the 1990 Atlanta CoCoFest and traded messages with you
on the Hayes BBS for awhile prior to the MM/1 unveiling.

  CP was made by Jamie S. Wilmoth.  I though MV was distributed by the OS-9
user group (not sure about that) and was written by Eric Williams.  Both
programs were obtained from either CIS or Delphi (not sure which) and are also
available on my BBS (405-752-8955).

  Another way to test this may be with Dupfile by Brian C. White, another
program I've seen in use.  It does with MV and CP -m does except for the
removal of the original directory reference.  In essence, it creates a second
copy of a directory enttry elsewhere on the directory tree from the original
and increments the FD.LNK byte in the file descriptor sector.

  Using the old RBF, if you tried to delete a file whose link count was greater
than 1, only the requested directory entry was "nulled" and the link count was
decremented.  Deleting the last copy of the file would result in reallocation
of that file's space in the FAT and apparantly blank out the sector references
in the file descriptor.   Curiously enough, the link count byte (even under the
old RBF) does not get set to $00 when the last copy of the file is deleted.

   ...But of course, that byte is irrelevant in such a case.

  I hope this helps.  Thanks for listening.
