'set' and 'render' together? access set variables from different view?

This seems like a very simple question, but I have been struggling
with it for quite a while. How can I use the 'set' function and then
the 'render' function while still being able to access my set
variables from the view? It seems to me that 'set' only makes
variables available in the view that matches the action. How can I get
around this?

e.g.

//exampleController

$this->set('a', $a);
$this->render('index');

//index.ctp

<?php echo $a ?>;
