Is there a way to pass every variable in a controller action, to the view automatical

Is there a way to pass every variable in a controller action, to the view automatical

So instead of 

PHP Code:

<?php
class News extends CI_Controller {
        public function index()
        {
                $data['test'] = "hello";
        }
} 


I can have

PHP Code:

<?php
class News extends CI_Controller {
       public function index()
       {
               $test = "hello";
       }
} 


And I can echo $test in the view and the word "hello" appears as the variable is passed automatically to the view without me having to manually pass it myself.
