    MIME provides basic composition commands that allow you to create a
    text file in MIME compliant format: NEW, OPEN/DRAFT, ADD, EDIT.

    Use the NEW command, which runs the editor specified in the VMSMAIL
    user profile, to create a text message. You are prompted for a
    filename if one is not specified.

 	MIME> NEW [filename]

    Or you can use the OPEN/DRAFT command to continue editing a previous
    MIME message that was composed and saved.

         MIME> OPEN/DRAFT [filename]

    Then use the ADD and REMOVE commands to add attachments (or parts)
    to the message or to remove them. Attachments are such as binary
    image files, sound files, and compound documents, and also text.

         MIME> ADD filename /CONTENT_TYPE="image/gif" /ENCODING=base64

 	MIME> REMOVE n

    Where "n" is the attachment number. Use the LIST command to list
    attachments and their characteristics.

    Lastly, execute the SAVE command to write the composed outgoing
    MIME text file.

 	MIME> SAVE

    Note that the MIME command SHOW FILE_TYPES lists the file types
    and their default settings for the  ADD command. Other optional
    file types: the file extension, its Content-Type/subtype, and the
    encoding to use,  are defined in MIME$FILETYPES.DAT file.

    For more help, see the ADD command and SHOW FILE_TYPES
    MIME$FILETYPES.DAT command.
