<h1 class="topictitle1">Message queues in break mode</h1>
|
|
<div><p>A break-handling program can be called whenever a message of equal
|
|
or higher severity than the severity code filter arrives on a message queue
|
|
that is in break delivery mode.</p>
|
|
<p> To request a break-handling program, you must specify the name of the
|
|
program and break delivery on the same <span class="cmdname">Change Message Queue (CHGMSGQ)</span> command.
|
|
The break handling program must receive the message with the <span class="cmdname">Receive
|
|
Message (RCVMSG</span>) command so the message is marked as handled and
|
|
the program is not called again. There is an IBM-supplied break-handling program
|
|
that you can use by default on the <span class="cmdname">Change Message Queue (CHGMSGQ)</span> command.
|
|
For example:</p>
|
|
<pre>CHgMSGQ MSGQ(name) DLVRY(*break)</pre>
|
|
<div class="note"><span class="notetitle">Note:</span> This program cannot open a display file if the interrupted program is
|
|
waiting for input data from the device display.</div>
