I didn't understand very well the point but , I think that you want to update variables ( written by you frequently on a text document or something similar , and then display it on your flash movie without needing to update it .I could explain how to do it by myself but there's no need , you will get better with a tutorial.
Jeff has also a tute for that , here's the link :
