Thanks for the reply. But that was just a cut-and-paste error. I don't
actually have the version quoted as the parallel statements are
commented in my copy. Without the parallel, the commas should not be
present. When I removed the comments to include the code in my message,
I forgot to put the commas back.
I'm still stymied by the obtuse Groovy error and hoping for some
enlightenment.
