XYplorer Beta Club

I was reading awhile ago that the regular expression engine used in xyplorer is an import of another program and I was wondering whether xyplorer's script engine is an import as well. I noticed that default variables are possible with the new functions in the recent release and I didn't even see that listed in his examples, so I was wondering if it's an import. It's obviously PHP like in nature.

By the way, by default I mean:

echo tempFunction(1); //Will echo default
echo tempFunction(1, 1); //Will echo 1

function tempFunction($a, $b="default") {
return $b;
}

the regex engine is "imported" from, and XY is written in VB6 VB5.
But the scripting engine, while modeled after PHP, is entirely Don's own creation.

Thank you I was just curious. Love the new functions, that's a huge improvement for such a minor upgrade.
