Advanced Program-to-Program Communication (APPC) or <span class="keyword">iSeries™</span> conversations in the job that

dropped or kept active for the source job.</p>

<dd>Specifies that once each DDM conversation is started for the source job
|

it is kept active at the completion of a source program request, and it waits
|

for another request to be received from the same or another program running

in the job. This is the default value.</dd>

<dt class="dlterm">*DROP</dt>

<dd>Specifies that each DDM conversation started in the source job is to be

automatically dropped when both of the following items are true: no request

|
from the source server program(s) running in the job is being processed in

the conversation, and all the DDM files are closed and all objects that were
