  $ EDIT/ACL/JOURNAL=COMMONACL.SAV MECH1117.DAT

      With this command, you create a journal file named
      COMMONACL.SAV. The file contains a copy of the ACL and
      the editing commands used to create the ACL for the file
      MECH1117.DAT.

      If the editing session is interrupted, you can recover your
      edits by specifying the name COMMONACL.SAV with the /RECOVER
      qualifier.

  $ EDIT/ACL/CLASS=RESOURCE/JOURNAL=ZERO_RESOURCE.TJL [0]

      If you edit an ACL for the resource domain [0], the ACL editor
      attempts to create the file [0].TJL on the default device
      and fails. To create an ACL for the resource [0], you must
      specify a different name for the journal file (as shown in this
      example) or suppress the creation of a journal file with the
      /NOJOURNAL qualifier.
