I am trying to add a marquee - type scroller to my site. However, I would like the text to scroll in a circular fashon like:
abc...abc...abc

not abc across the window then start over.

hints, suggestions and complete solutions are welcome!

Thanks works great!
When trying to understand the source, I do not comprehend some of the statement such as:
document.getElementById? document.getElementById("iemarquee2") : document.all.iemarquee2
Could you direct me to a resource so that I can learn these constructs

one ? two : three is equivalent to

if (one) {
two;
} else {
three;
}

Exam answer so the code snippet says
If the browser supports DOM then find the node for the Marquee otherwise use the collections method to find marquee2.

Yes indeed. It also returns a value, so you can use it in statements like this:

var one = two ? three : four;
where a variable called one is created, then if two is true, assign it the value of three; otherwise, assign it the value of four.
