Here's some code someone showed me more creating button settings from a text file.

protected function loadSettings():void
            {
                var varLoader:URLLoader = new URLLoader();
                varLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
                varLoader.addEventListener(Event.COMPLETE, onSettingsLoaded);
                varLoader.load(new URLRequest(currentFile.nativePath + "/buttons.txt"));
            }

            protected function onSettingsLoaded(event:Event):void
            {
                var varLoader:URLLoader = URLLoader(event.target);
                var varButtons:URLVariables = varLoader.data;
                var buttons:Dictionary = new Dictionary();
                for(var label:String in varButtons){
                            buttons[label]=varButtons[label].toString().split(",");
                }
                    //use parsed buttons dictionary
            }

The buttons.txt I created looks like this:
button1,button2,button3

Would I start a loop here:?
//use parsed buttons dictionary

Or would I first have to put the strings into an array?
