Thnx for the reply GrandFather.... suppose I have this in my code: 
use Tk;
my $main=new MainWindow;
$main->title("Test window");
<I print a message "msg" in the window at this line>;
MainLoop;

[download]
Now how do I add another message to the window.. ? My requirement is.. I should update the window after the MainLoop statement. Just let me know how exactly to use UPDATE()??
