     The SAY utility consists of two files:

          SYS$SYSTEM:SAY.EXE
          SYS$SHARE:SAYSWITCH.EXE

     These files must be installed as known images in order for the utility
     to function correctly.  Therefore, the following lines should be added
     to the site-dependent startup procedure ([SYSMGR]SYSTARTUP.COM) in the
     section where other images are installed:

          SAY/PRIV=(CMKRNL,GROUP,WORLD,OPER,SYSLCK)/SHARE/OPEN/HEADER
          SYS$SHARE:SAYSWITCH/SHARE/WRITE

     NOTE:  Do not precede the above two lines with dollar-signs

     The following two lines must be added AFTER  the install  in the site-
     dependent startup procedure:

          $ SAY :== $SAY
          $ SAY/INITIALIZE

     In addition, the following line must be  added  to  the  system  login
     procedure that all users execute:

          $ SA*Y :== $SAY

     SAY will then be available to all users logging in after these changes
     are made.


     The following text can be added to the system help file using the 
     librarian.

1 SAY_$
 Allows sending of messages to any interactive user on the system.

 Format:

      SAY [TO] username message-text
2 Parameters
 username

  Specifies the login username of the recipient.  If you specify an
  asterisk (*) as the username, the message will be sent to the last
  recipient used.

 message-text

  Specifies message to be displayed at all terminals logged in under
  the username of the recipient.
2 Qualifiers
/DISABLE

 Blocks messages from being sent to your current process.  This is reset
 when you logout and has no bearing on other processes logged in under
 your username.  No username or message-text can be specified with this
 option.
/ENABLE

 Allows messages to be sent to your process.  Counteracts the /DISABLE
 qualifier.  No username or message-text can be specified with this
 option.
/INITIALIZE

 Initializes the global database so that all processes are receiving
 messages.  This qualifier requires that you have a system UIC or the
 user privilege SYSPRV.
/QUERY

 Allows you to determine who your "current correspondent" is.
/SILENT

 Prevents bells from being added to message.
