<div><p>You can query remote files using the <span class="cmdname">Open Query File (OPNQRYF)</span> command,
but only if the remote files are on a target <span class="keyword">iSeries™ server</span> or
a target <span class="keyword">System/38™</span>. </p>
<div class="section"><p>If multiple remote files are specified on one <span class="cmdname">OPNQRYF</span> command,

<div class="section"><p>If the target server is an <span class="keyword">iSeries server</span> or
a <span class="keyword">System/38</span>, a query request
is created and sent to the target server using the DDM file that the query
refers to. If the target server is other than an <span class="keyword">iSeries server</span> or
a <span class="keyword">System/38</span>, the query request
cannot be processed and an error message is created. However, the query utility
on the <span class="keyword">System/38</span> can be used
to query remote files that are other than <span class="keyword">iSeries</span> files. </p>
