The context was roughly:
getURL("http://www.google.com");
Now, in Actionscript 3.0, you just use:
var getGoogle:URLRequest = new URLRequest("http://www.google.com");
navigateToURL(getGoogle);
See, it's simple now...
Ok, so it's not hard, but it is just one example of the major changes between AVM1 and AVM+
I feel like I have to completely relearn Actionscript... *sigh*
