Help with mailto: URGENT

Ok, well im trying to simply open a mail client and have a preset message with the click of a button.

This is what i have, and it works so far.

var sendfriend_btn:Button;
sendfriend_btn.onRelease = function()
getURL(“mailto:[email protected]”);

How do i add a [COLOR=red]subject[/COLOR] and some [COLOR=red]body text[/COLOR] to this mail function???
should be an easy one for you guys.
