You could do it like this:
In JavaScript for your html, do:
function setStatus(toWhat){
window.status = toWhat
}
Then in your app, do:
flash.external.ExternalInterface.call("setStatus", "my message");
(I'm not 100% sure that's the classpath to ExternalItnerface)
Note, too, that this won't work locally because of the Flash player
security.
Thanks,
