First of all Greg, I'd make sure that it doesn't use any nibblecounts, and the
like..  second of all, you'd have to search the disk for jsr's to the ProDos
Mli  (a jsr $BF00)..  then you'd wanna look at the byte after that, which
tells the mli which operation to perform..  the bytes for disk access are:
      $80 Read_block
      $81 Write_block
      $C2 Rename
      $C1 Destroy
      $C3 Set_file_info
      $C4 Get_file_info
      $C5 Online
      $C6 Set_prefix
      $C7 Get_prefix
      $C8 Open
      $CA Read
      $CB Write
      $CC Close

  the ones i'd search for would be the online cmd, the set_prefix and
get_prefix cmds...  Those are what I'd expect them to use....
    Of course, this is all assuming that they are using the mli as their file
searching utility, and not basic system...
