/sys$common/syshlp/helplib.hlb EDIT, /ACL, /JOURNAL, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    By default, the ACL editor keeps a journal file containing a
    copy of modifications made during an editing session. The journal
    file is given the name of the object and a .TJL file type. If
    you specify a different name for the file, do not include any
    wildcard characters.

    To prevent the ACL editor from creating a journal file, specify
    /NOJOURNAL.

    If your editing session ends abnormally, you can recover the
    changes made during the aborted session by invoking the ACL
    editor with the /RECOVER qualifier.
