Send warning or message to user(s)

Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $SirWarn function, because it is very easy to do the same thing using a Daemon.

The $SirWarn function is used to send a warning or message to the specified user or users. If the user invoking $SirWarn is a system manager or system administrator, $SirWarn acts like a WARN command; otherwise it acts like an MSG command.

Syntax

%rc = $SirWarn (user, message)

Syntax terms

%rc	A numeric variable that is set to indicate the success of the function.
user	Identifies the user(s) to receive the warning. If this argument is the string `OPR`, the warning is sent to the operator's console (or virtual console under CMS). If this argument is a valid user number, the warning is sent to the indicated user number. If it is neither `OPR` nor a valid user number, it is treated as a userid, and the warning is sent to every user logged on to this userid.
message	The text of the warning to be sent to the user(s) indicated by the `user` argument.

Return codes

0 - Warning issued 1 - User(s) not logged on 2 - Insufficient storage 3 - Parameter missing (either userid or message)

Examples

The following statement sends a warning of an application error to the operator:
%rc = $SirWarn('OPR', 'Severe application error for user' WITH $USER)
This statement sends a warning to user 57 to leave subsystem BARNEY:
%rc = $SirWarn(57, 'Please leave subsystem BARNEY')
This statement sends a warning to all users logged on as HOMER to call Marge:
%rc = $SirWarn('HOMER', 'Please call Marge')
