    <p>Let's say I have the following simple script:</p> <pre><code>print "ID : "; $ID = &lt;&gt;; system (`comp program $ID`); exec "task --shell"; </code></pre> <p>When I use:</p> <p><code>perl foo.pl | tee log.txt</code></p> <p>The showing up problem is getting on screen a blink sign echo (waiting for the ID enter) before I even see the "ID : " (print instruction).</p> <p>I need to keep on a log file all running output script (very long), notice that at the start of the run I have an interactive part that also need to be kept.</p> <p>Is there a way inside PERL script or outside it, that keep the output stream exactly as it shown out on the screen, and what do you think is the simple &amp; efficient way to conduct it?</p> <p>I've noticed the IO::Tee , File::Tee moudles and Log4perl - someone can help me find the best way to use it ?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
