The SET SIGNATURE_FILE command enables you to automatically
    append a file to the end of a mail message whenever you use
    the ANSWER, FORWARD, MAIL, REPLY, or SEND command. An example
    of a signature file is a text file formatted as business card,
    containing the user's company name, address, telephone, and
    Internet address.

    The SHOW SIGNATURE_FILE command shows whether you have specified
    a default signature file and displays the name of that file. (The
    SHOW ALL command also displays signature file information.)

    The SET NOSIGNATURE_FILE command disables the default setting.
    No signature file will be appended automatically to any mail
    messages until you re-enter the SET SIGNATURE_FILE command.
    If you want to temporarily disable or override (to append
    a different signature file) the default setting only while
    sending a particular mail message, use the /SIGNATURE_FILE or
    /NOSIGNATURE_FILE qualifier with the ANSWER, FORWARD, MAIL,
    REPLY, or SEND command.

    You can also set, disable, or override the default signature
    file at the DCL level by using the /SIGNATURE_FILE or
    /NOSIGNATURE_FILE qualifier with the DCL command MAIL.

    Note that when you create a mail message that includes a
    signature file, that message requires more temporary disk space
    than a conventional message because temporary files are created
    during the operation. After the message is sent, those temporary
    files are deleted.

    Format

      SET SIGNATURE_FILE  file-name

      SET NOSIGNATURE_FILE

      SHOW SIGNATURE_FILE

1  –  Parameter

 file-name

    Specifies the name of the default signature file (text) that will
    be appended to each mail message.

    When specifying the signature file name, note the following:

    o  If you do not specify a file type, the default is .SIG.

    o  If you do not specify a directory, the Mail utility will
       search for the signature file in your mail directory.

2  –  Examples

    1.MAIL> SET SIGNATURE_FILE BUSINESS_CARD.SIG

      In this example, the user specifies that the file
      BUSINESS_CARD.SIG is to be appended to every mail message sent
      using the FORWARD, MAIL, REPLY, or SEND command.

    2.MAIL> SHOW SIGNATURE_FILE
      Your default signature file is BUSINESS_CARD.SIG.

      This example shows how to use the SHOW SIGNATURE_FILE command
      to determine if a signature file is currently set.
