Thanks Dragan.

I knew that divide by zero produced this error and I tried (at least I think I tried)
? myfield = 1/0 and kept getting false. Maybe it has something to do with the width of the field N(16).

I tried your solution in a small test and it worked so I'll look and see if it will work with my larger field.

FWIW I also found that
myField > 999999999999999999999999 also returns true for the overflow field.

As always, your help is appreciated.
