<h1 class="topictitle1">Display DDM remote file records</h1>
<div><p>The <span class="cmdname">Display Physical File Member (DSPPFM)</span> command
can be used to display a remote file on a target server.</p>
<div class="section"><p>For performance reasons, however, whenever possible, you should
use display station pass-through to sign on the remote server, and display
the file directly. When display station pass-through is used, only the display
images are transmitted over the communications line. When DDM is used to access
the remote file, each record is transmitted separately over the line, which
requires many more transmissions.</p>
</div>
<div class="section"><p>If pass-through cannot be used (for example, if the remote file
is not on an <span class="keyword">iSeries™ server</span>, a <span class="keyword">System/38™</span>, or a <span class="keyword">System/36™</span>,
or if pass-through is not configured on your server), direct record positioning
rather than relative positioning should be used whenever possible. For example,
if record number 100 is being displayed and you want to see record number
200 next, that record is accessed faster if you enter 200 in the control field
instead of +100. The results are the same, unless the file contains deleted
records.</p>
