/EDIT[=keyword[,...]]

    Specifies for interactive PMDF MAIL sessions, which commands
    implicitly invoke the editor. The accepted keyword values are

 ALL

    Always invoke the editor in conjunction with all commands that
    accept the /EDIT qualifier.

 COMMAND_LINE

    In conjunction with /EDIT=SEND, invoke the editor even when
    sending a file or message from the DCL command line.

 DIRECTORY

    Always invoke the editor to display DIRECTORY and
    DIRECTORY/FOLDER listings.

 FORWARD

    Always invoke the editor to edit messages being forwarded with
    the FORWARD command.

 HEADER

    By default the message's header is always displayed in the
    editor. To inhibit this, specify /EDIT=NOHEADER.

 KEPT[=editor-process-name]

    Initially invoke the editor as a subprocess; re-attach to the
    subprocess for subsequent editor operations.

 NONE

    Never invoke the editor unless explicitly requested to do so with
    the /EDIT qualifier.

 READ

    Always invoke the editor to display messages being read with the
    READ, CURRENT, BACK, NEXT, FIRST, and LAST commands.

 REPLY[=EXTRACT[=quote]]

    Always invoke the editor to edit messages being replied to with
    the ANSWER or REPLY commands. If the optional EXTRACT keyword
    is specified, then the content of the message being replied to
    will be included in the reply. To specify a text string to use
    to quote each line of the extracted message text, specify a value
    for the EXTRACT keyword. For instance, to quote each line with
    the two characters "> ", invoke PMDF MAIL with the command

    $ PMDF MAIL/EDIT=REPLY=EXTRACT="> "

 SEND

    Always invoke the editor to compose messages being sent with the
    MAIL or SEND commands.

    If /EDIT is specified without any keyword values, then
    /EDIT=(SEND,REPLY) is assumed.
