<h4 id="_during_config_file_processing">During Config File Processing</h4>
<div class="paragraph"><p>It is often helpful to know the content of variables in various
contexts as Megatest does the actions needed to run your tests. A handy technique is to force the startup of an xterm in the context being examined.</p></div>
<div class="paragraph"><p>For example, if an item list is not being generated as expected you
can inject the startup of an xterm as if it were an item:</p></div>
<div class="listingblock">
<div class="title">Original items table</div>
<div class="content monospaced">

<div class="content monospaced">
<pre>[items]
DEBUG [system xterm]
CELLNAME [system getcellnames.sh]</pre>
</div></div>
<div class="paragraph"><p>When this test is run an xterm will pop up. In that xterm the
environment is exactly that in which the script "getcellnames.sh"
would run. You can now debug the script to find out why it isn&#8217;t
working as expected.</p></div>
