Oh, I just threw that together in about 30 seconds by
adding an INDICES keyword to the SetIntersection program
described here:

I probably got it wrong. While you are fixing it,
you probably want to add some error handling, too,
so you can figure out when there are no matches in
the intersection. :-)
