1 TALK
 Invokes the ICR TALK utility to talk with other users on the system.

 Format:
                 TALK[Qualifier] [User_name] [Message]
2 User_name
 This parameter specifies the name of the user you wish to  talk  with.
 If  the  user is logged in at more than one terminal, messages will be
 sent to all such terminals.  If one of those  terminals  begins  using
 talk, messages will be sent to that terminal only.

 The user name ME may be used to talk to yourself.  This is useful when
 using talk for batch job status notification.

 The user name ALL may be used to talk to all users on the system.  You
 must have the necessary privilege (OPER) to use this option.

 If you specify the name of a user who is either not  currently  logged
 in  or  who  has  indicated  that  his  terminal  is busy, you will be
 prompted as to whether you would like to send mail.
2 Message
 If you include a message on the command  line,  talk  will  send  that
 message and then exit.
2 Conversation
 Once you have specified a user_name or terminal, all  lines  typed  at
 your terminal will be displayed on the user's terminal or sent as mail
 to the user.  Type control-z to end your conversation.
2 Busying_your_terminal
 If you would like to prevent anyone from talking to you, you may  busy
 your  terminal  by  using the SET TERMINAL /NOBROADCAST command.  This
 command, however, will also prevent the system manager from  notifying
 you about system malfunctions, so use it at your on risk.

 The SET TERMINAL /BROADCAST command will allow  other  users  to  talk
 with you again.
2 Batch_job_status
 You may use TALK from a batch job to notify you about  the  status  of
 the  job  by  placing  TALK commands at various stages in your command
 file.  If you are not logged in when the TALK commands are encountered
 TALK will automatically send the messages by mail.
