<h1 class="topictitle1">Completion and diagnostic messages</h1>
|
|
<div><p>Using the <span class="cmdname">Send User Message (SNDUSRMSG)</span> command,
|
|
you can send diagnostic and completion messages.</p>
|
|
<p>You can send these message types to any message queue from your CL procedure
|
|
or program. Diagnostic messages tell the calling program or procedure about
|
|
errors detected by the CL procedure or program. Completion messages tell the
|
|
results of work done by the CL procedure or program.</p>
|
|
<p>Normally, an escape message is sent to the message queue of the calling
|
|
program or procedure to tell the caller what the problem was or that diagnostic
|
|
messages were also sent. For a completion message, an escape message is usually
|
|
not sent because the requested function was performed.</p>
|
|
<p>For an example of sending a completion message, assume that the system
|
|
operator uses the command entry display to call a CL program SAVPAY to save
|
|
certain objects. The CL program contains only the following procedure which
|
|
saves the objects and then issues the following completion message: </p>
|
|
<pre>PGM
|
|
SAVOBJ OBJ(PAY1 PAY2) LIB(PAYROLL) CLEAR(*YES)
|
|
SNDPGMMSG MSG('Payroll objects have been saved') MSGTYPE(*COMP)
|
|
ENDPGM</pre>
|
|
<p>If the <span class="cmdname">Save Object (SAVOBJ)</span> command fails, the CL procedure
|
|
function checks and the system operator has to display the detailed messages
|
|
to locate the specific escape message explaining the reason for the failure.
|
|
If the SAVOBJ command completes successfully, the completion message is sent
|
|
to the call message queue associated with the program that displays the command
|
|
entry display.</p>
|
|
<p>One of the advantages of completion messages is their consistency with
|
|
IBM-supplied commands. Many IBM<sup>®</sup> commands send completion messages indicating successful
|
|
completion. Seeing the type of message sent to the job log can assist in
|
|
problem analysis.</p>
