Hi Eugene,

Clever solution.

It didn't come right back so I interrupted it. Guess it would do all those multiplies by zero.

Does anyone know how to define it to avoid that?

Thanks.

Michael

Check that by experiment in ghci or by looking at the source:

Prelude*> product [0..]

Or search "product" at http://holumbus.fh-wedel.de/hayoo/hayoo.html
and click on one of the Source links.
