Keep[=(Recovery,Journal)]

    Determines whether the journal file, the recovery file, or both,
    are deleted when the editing session ends. The options are:

    o  Recovery-Saves the journal file used for restoring the ACL.

    o  Journal-Saves the journal file for the current editing
       session.

    You can shorten the Journal and Recover options to J and R,
    respectively. If you specify only one option, you can omit the
    parentheses.

    You must specify the Edit qualifier to use this qualifier. If you
    specify the Edit qualifier but do not specify the Keep qualifier,
    both the journal file for the current editing session and the
    journal file used for restoring the ACL are deleted when the
    editing session ends.
