VMS Help SET, DIRECTORY, Examples  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    1.$ SET DIRECTORY/VERSION_LIMIT=5/CONFIRM [VERCAMMEN...]

      The SET DIRECTORY command in this example sets a version
      limit of five for all files in the VERCAMMEN directory and
      all subdirectories of [VERCAMMEN]. The /CONFIRM qualifier
      requests that you confirm whether the specified directory
      should actually be modified. Note that it affects only the
      files created after the command is entered.

    2.$ SET DIRECTORY/OWNER_UIC=[360,020] [WOERTMAN],[MOSER]

      The SET DIRECTORY command in this example modifies both the
      [WOERTMAN] and [MOSER] directories, changing their owner
      UICs. Using the OWNER_UIC qualifier requires SYSPRV (system
      privilege).
