Code Question...

I hope this is the correct place to post this.

I'd like to know what the following code is for:

<SCRIPT TYPE="text/javascript">
<!--
function popup(url, winpopup)
{
if (! window.focus)return true;
var href;
if (typeof(url) == 'string')
href=url;
else
href=url.href;
window.open(href, winpopup, 'width=300,height=250,scrollbars=yes');
return false;
}
//-->
</SCRIPT>


Thanks

It opens a new browser for a given url of dimensions 300x250 with a scroll bar. Like vB for the attachments upload box, but maybe not that particular piece of code. I never looked.
