/EDIT
       /NOEDIT

    Invokes a text editor to edit the message you are sending. Unless
    you select a different editor, the TPU-based EVE editor
    is invoked. The /NOEDIT qualifier overrides the /EDIT default
    qualifier if you entered the DCL command MAIL/EDIT.

    You can use the /EDIT qualifier with the /LAST qualifier to edit
    the message before sending it.
