1 SEND
 The SEND utility enables a user to send a message to another user.
 The utility prompts for the user's name or the terminal ID of the
 receiving process.  Maximum of 250 characters can be sent.  Message
 is terminated and sent by entering <CNTR>-Z.

 If the receiver has allocated more than one terminal or does not
 have an allocated terminal, then only the terminal ID can be used.
 Likewise, if the receiver is not in the sender's UIC group and the
 receiver's name is not unique, then only the terminal ID is
 allowed.  (Group names are searched before non-group names.)

 The receiver can determine that a terminal ID is required to reply
 to the sender since the sender's terminal ID will be listed with
 the message.  (Sender's terminal ID is not listed if receiver can
 reply by specifying the sender's name.)

 Format:
     $ SEND name

 where
     name is the process name or terminal ID of the user to send to.
