RE: XFOOT

["Richard B Baird" <rbaird@xxxxxxxxxxxxxxxxxxxxx>]

First of all, I would advise against xfooting an entire array into one of
it's elements - sloppy and scary, and cause for great confusion to anyone
who might try to change the program after you.

Next, with 9000 elements, how can you insure that all of them added up
won't exceed 9999999.99 ?

if the first two elements were over 5,000,000.00 you would already have
exceeded your limit for that xfoot.

If it's not possible for one of the elements to be that big, make the array
element smaller (7,2? 5,2?  whatever).   If it is possible for it to be
that big, then you won't be able to xfoot into itself.

ether way, you should use a separate field as the xfoot result, and make it
big enough to hold 9000 * the maximum array element value.
