>Hi all:
>I have a program that searches for a [CODENUMBER] and then checks the value of the [BARCODE] field. I want some action taken if the field is .NULL. I know the field is .NULL. because that is how it shows in the field and i can see that value in a debug window. However, the line

No, it will evaluate as .NULL. Any comparison with .NULL. returns .NULL. This is because there is no meaningful comparison to be made, since .NULL. has no value or data type. This is not the same as EMPTY() which can be applied to various data types.
