Format: EXTRACT/ATTACHMENT=attachment-number [filename]

    NOTE: The /ATTACHMENT qualifier is required with EXTRACT.
    This qualifier specifies the number of the attachment as
    displayed by the LIST command. In a single part message,
    no attachment number is displayed. For this case specify
    attachment number one.

    EXTRACT extracts the specified attachment to a file in its
    native file format or in another format specified by the /FDL
    qualifier.  By default, the attachment is written to a file in
    the default directory, using the name specified by the
    Content-Disposition header of the attachment. If no file name
    is provided, the program prompts for one. A file name can be
    specified in the command to override the value of the
    Content-Disposition header.

1    /FDL

    /FDL=filename

    Specifies a File Descriptor Language (FDL) definition file to use
    when converting the specified attachment into an output file. Use
    this qualifier when the desired file characteristics differ than
    those produced by the MIME utility default settings, or are different
    than those specified in the MIME$MAILCAP.DAT file

    Note that the /FDL qualifier will override the default FDL file
    specified in MIME$MAILCAP.DAT file (if one exists).

    FDL files can be created with the ANALYZE/RMS/FDL command and also
    created and edited with the EDIT/FDL command.
