Sending variables from one Flash file to another

Is there a good tutorial (or help) on how to send variables from one swf to another?

Assuming they are on different domains,

Thanks very much.

Use LocalConnection, if you want both swf's to be open at the same time
(Refer to Adobe LiveDoc)

(OR)

Use FlashVars(swf1 will pass variable to the html page that holds your swf2. This swf2 html page will use FlashVars to push the variable into swf2)

Thanks heaps e tit,
I'll see if I have anymore questions when I try it out.
