Well, this is exactly the kind of thing (declaring field type
on the fly) that is trivial to do if the program was written
as an object. It is much harder to do written the way it
is currently. I'll leave it up to you to turn it into an
object and send me the result. :-)
P.S. Don't forget to include Struan's request for
floating value formatting. :-)
