ActionScript (like javascript) is an asynchronous programming language so each RPC call you make does not block while the code fetches the results. Because of this, pretty much every asynchronous call does not return the result directly... instead it returns a token which you can use to register a callback function which gets the result. So this line of your code below isn't going to return a Year - it returns an AsyncToken.
year = Year(ro.retrieveYear(1)); With that token you can register a callback function that is given the "year". The other thing Java programmers get tripped up by is the fact that the flash player will not actually initiate any RPC ops until your current code completes. Thus it is safe to assign to the returned token after the call is made as long as you do so before the current "frame" completes.
