  /NODIRECTORY

   Sets  or resets the  directory  attribute of a file. This  qualifier
   allows to set  the directory bit of a file which was mistakingly
   reset by the 'SET FILE/NODIRECTORY' command. If it is done on a non-
   directory   file,  then  access   to  that  directory  will  give  a
   'BADIRECTORY' error.
