How do I use 'setInterval'

[Digital Pimp]

Hi
I have the following script on a movieclip which scrolls the text across the screen. I want to delay the start point of the scroll by say 5 seconds. I think I should use setInterval in some way but can't quite suss it out...anyone???? :confused:

onClipEvent (load) {
_parent.text = "The text I want to scroll "
}
onClipEvent (enterFrame) {
tmp = _parent.text.substr(0, 1);
_parent.text = _parent.text.substr(1, _parent.text.length-1)+tmp;
}


TIA
