Previously, in ActionScript 2.0, you could pass variables along the query string or using FlashVars and the variables would be available in _level0, in ActionScript 3.0, it is a bit different . In Actionscript 3 variables that are passed in through query string have been moved to the parameters property of LoaderInfo instance. Here’s a real simple way to retrieve flash variable in Actionscript 3

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="550" height="400" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0">
     <param name="src" value="somefilename.swf?fileName=info" />
     <embed type="application/x-shockwave-flash" width="550" height="400" src="somefilename.swf?fileName=info"></embed>
</object>

var tf:TextField = new TextField();
tf.autoSize = TextFieldAutoSize.LEFT;
tf.border = true;
addChild(tf);
 
tf.appendText("params:" + "\n");
try {
    var keyStr:String;
    var valueStr:String;
    var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
    for (keyStr in paramObj) {
        valueStr = String(paramObj[keyStr]);
        tf.appendText("\t" + keyStr + ":\t" + valueStr + "\n");
    }
} catch (error:Error) {
    tf.appendText(error.toString());
}
