implementing n external .js file??

[source]

I would really like to use a javascript (.js) file within a flash movie... Could someone tell me how this is done?

To my knowledge, using FS Commands is how Flash deals with JavaScript, and it works through a function called "doFunction" (or some such nonsense) on the HTML page. Any further functions you want to call have to be specified in doFunction. There's a section in the HELP files with Flash 4 about it ... have a gander and see what you think.
