/ENTIRE[=keyword[,...]]
       /MESSAGE[=keyword[,...]]
       /PART[=keyword[,...]]

    For interactive PMDF MAIL sessions, specifies message content
    scope for EXTRACT, FORWARD, PRINT, and REPLY commands. The
    accepted keyword values are EXTRACT, FORWARD, PRINT, REPLY, ALL,
    and NONE.

    The /ENTIRE qualifier specifies which commands by default act
    upon the entire message. The /MESSAGE qualifier specifies
    which commands by default act upon only the current portion of
    the message which constitutes an entire message. (Note that a
    message may contain one or more messages as subparts.) The /PART
    qualifier specifies which commands by default act upon only the
    current message body part.

    Specifying /ENTIRE without any qualifiers implies /ENTIRE=ALL;
    specifying /MESSAGE without any qualifiers implies /MESSAGE=ALL;
    and specifying /PART without any qualifiers implies /PART=ALL.
