Hi Lakshmi,
You can do this just put all the script in the mxml block in seperate AS file as shown below... Observe that I have included an AS file named Script.as and removed the script block form mxml and moved to this Script.as file. Place the Script.as file in your src folder ....
// Main mxml file....
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="onCreationComplete()">
    <mx:Script source="Script.as"/>
<mx:TextArea id="textArea" width="300" height="100" />
<mx:Button id="myButton" label="Click ME"/>
</mx:Application>
//Script.as file
import mx.controls.Alert;
private function onCreationComplete():void
myButton.addEventListener(MouseEvent.CLICK, onButtonClick);
private function onButtonClick(event:MouseEvent):void
textArea.text = "This is the Text assigned in an ActionScript method....";
Thanks,
