Sends a message to one or more users. The MAIL command works like the
  SEND command.

  MAIL prompts you first for the name of the user(s)  to  receive  the
  message.  You reply with the user name(s) or with the file name of a
  distribution list file(s), in the following format:

  [[nodename::]username,...] [,] [@listname[,...]]

  If you have entered the SET CC_PROMPT command or used the /CC_PROMPT
  qualifier,  you can then specify names of users  to  receive  carbon
  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  MAIL
  command.

  You can include a file specification with the MAIL command.  If  you
  specify  a file with the MAIL command, the text in that file is sent
  to the specified user(s).  If  you  do  not  specify  a  file,  MAIL
  prompts you for the text of your message.

  Enter the message that you want to send; then press <CTRL/Z>.   Note
  that  once you have typed a line and pressed RETURN, there is no way
  to edit it.  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.  You then receive the MAIL> prompt.  CTRL/Z exits  you
  from MAIL.

   Format:

       MAIL [file-spec]
