Sends a message to one or more other users. You can use the SEND
    command and the MAIL command interchangeably because they work
    the same way.

    Mail prompts you first for the name of the user or users to
    receive the message. Reply with the user names or with the file
    names of distribution lists, using the following format:

           [[node-name::]user-name,...] [,] [@listname[,...]]

    If you entered the SET CC_PROMPT command or used the /CC_PROMPT
    qualifier, you can specify names of users to receive copies of
    the message at the CC: prompt.

    Next, Mail prompts you for the subject of the mail. To avoid the
    Subj: prompt, specify the /SUBJECT qualifier with the SEND
    command.

    You can include a file specification with the SEND command. If
    you do, the text in that file is sent to the specified users. If
    you do not specify a file, Mail prompts you for the text of your
    message.

    Enter the message you want to send, then press Ctrl/Z. Note that,
    once you type a line and press Return, there is no way to edit
    it. Using the /EDIT qualifier enables you to edit the entire
    message before you send it. The /LAST qualifier enables you
    to send the last message. The /LAST qualifier used with the
    /EDIT qualifier enables you to edit the last message you sent.
    If you decide not to send a message you are typing but want to
    stay within the Mail utility, press Ctrl/C to abort the message.
    Ctrl/Y exits you from Mail.
