path-name

  Specifies the dictionary directories,  subdictionaries,  and  objects
  you  want  copied into the backup file.  The path name is optional if
  the /LIST qualifier is the only one used.  You can use the  wildcards
  %  and  *  in  the  last given name of the path name, and you can use
  either > or .> at the end of the chain.  You cannot use  @.   If  you
  are  using  a  terminal  of  the  VT200  family,  you  can  use 8-bit
  characters in path names.

  DMU assumes a > at the end of the chain as a default.

  Type "HELP specify path-name" for further information.

  file-specification

  Names the backup file.  Use the standard VMS file specification.  The
  default file type is .BAK.
