MPE/iX Commands Reference Manual Volume I
WARN
Sends an urgent message to jobs/sessions.
Syntax
{@ }
WARN {[#]Jnnn } [;message]
{[#]Snnn }
{[jsname,]user.acct}
Parameters
@ All users receive the message (including those
running in QUIET mode).
#Jnnn A job number (assigned by MPE/iX) for the job that
is to receive the message.
#Snnn A session number (assigned by MPE/iX) for the job
that is to receive the message. Only jobs
submitted on interactive devices can receive
messages.
jsname, user.acct The names of the job/session and user to receive
the message and the account name under which they
are running. (These names are the same as those
entered with the JOB or HELLO command.)
If several users are running under the same
job/session identity, MPE/iX sends the message to
all of them.
message The message text, consisting of any string of ASCII
characters containing no more than 67 characters.
The message is terminated by Return. Default is
that no message is printed.
Operation Notes
Sends an urgent message, interrupting any current pending read or write
in progress. The message appears on the list devices of all sessions
(even those that are QUIET) as:
OPERATOR WARNING: text
Messages sent with the WARN command are received by a job only if the job
was submitted on an interactive device.
The user has the option of running a session in QUIET mode. In that
case, TELL messages from other users are suppressed. WARN messages
generated at the system console, however, override QUIET mode.
NOTE Use caution when sending a warning to users. The WARN command
overrides a block mode screen.
Use
This command may be issued from a session, job, program, or in BREAK.
Pressing Break has no effect on this command. It may be issued only from
the console unless distributed to users with the ALLOW command.
Example
To send a WARN message to all sessions, followed by a WARN message to
session #S51, enter:
WARN @;THE SYSTEM WILL SHUTDOWN IN 5 MINUTES. PLS LOG OFF.
WARN #S51;LAST CHANCE TO LOG OFF GRACEFULLY.
