SetInterval repeat when finished looping forever

Question

Greetings,
The following setInterval example is right out of the Flash
documentation, and I'm using this method to periodically, create,
animate and fade out (using the tween class) some items on screen
This code from the docs traces the contents of an array,
passed as parameters, at one second intervals. What is the best way
to have it start again when completed, thus beginning again to
trace the first parameter-- and so on forever looping.
Thanks in advance to all you AS experts.

Yes, it does seem to be one of those things that a lot of
folks struggle with – I did too way back.
Just remember that it means, "keep doing what I tell you at
the agreed upon interval – until you are told to stop." I
think assigning the return value to a variable is a big part of the
confusion. Really it is just like getting a ticket in a bakery.
There can be many interval running at the same time, so to keep
them straight flash gives them a number – the first one is 1,
the next 2, and so on.
So all that we are doing with the assigning to a variable is
pulling the bakery ticket out of the machine and hanging on to it.
There is no way to know what the number will be until we pull it
out or what it was if we lose it. So we have to keep it around (by
putting it in a variable). Then later we can say, "Oh yeah,
remember interval 5, well cancel it now."
Remember too, that the internal Flash classes may also use
setInterval so you can never count on, "Well the last interval I
used was 4, so this next one will be 5."
