1	BROADCAST
     BROADCAST is a task which allows any user to send a one line
notice to another user on the system.  Its syntax is

	BROADCAST[/BOT] TTuu:"message...message...message"
or
	BROADCAST[/BOT] TXuu:"message...message...message"   (DMF-32)
or
	BROADCAST[/BOT] OPA0:"message...message...message"
or
	BROADCAST[/BOT] Username:"message...message...message"
2 Parameters
Terminal_Name

IF the text preceeding the ":" starts with a "TT", a "TX" or an 
"OPA0:, the target device is assumed to be a terminal and not a
username.  The terminals must exist.  They do not have to be logged on.


Username

If the form using the Username is used, the name may either be a valid
VMS login name or a logical name which translates to a login name.
In this case, BROADCAST will send a notification message to all terminals
the user is logged on to.  Alternatively, using the form specifying 
the terminal number, the message will be sent to the terminal regardless
of the user at the terminal.

Message

The message text should be enclosed in quotes.  The length is limited
to 80 characters.
2 Qualifiers
/BOT
Messages sent to DEC CRT terminals will erase the top 6 
lines of the screen and display the notice 2 lines down from the top.
However, the optional switch, /BOT, may be added to the command to force
the broadcast message to the bottom line of the terminal. 
2 Display_Area
Unless the /BOT switch is used, a message broadcast to a VT100 type
terminal will erase the top 6 lines of the display, sound the bell, 
and display the message downw two lines from the top.  The /BOT switch
forces the message to be displayed as if the terminal were a hard copy
terminal (ie the message appears at the bottom of the screen or at
the current text entry location).
2 Use
     VPW defines BROADCAST for users to use as needed.  However, to use
BROADCAST apart from VPW, define the symbol

	BROADCAST:==$SYS$SYSVPWFILES:BROADCAST

To properly work, BROADCAST must be installed with OPER, and WORLD 
privilege.
