</blockquote>



<p>I don't really do Javascript programming and was hard to google this but have seen something like this in a couple of different places (by good developers):</p>

<pre><code>document.writeln('&lt;scr'+'ipt src="'+pcheck+'" type="text/javascript"&gt;&lt;/scr'+'ipt&gt;');
</code></pre>

<p>With the split always between the r and the i. What does this achieve?</p>
