DISABLE is used in input or menu processes to make a button unavailable for user selection. This can be used for buttons that are conditionally unavailable depending on prior entries, user qualities, databases, interactive phase, and so forth.
The application ID must be left blank if a button reference name (assigned when the button is painted on the image) is used. Otherwise, use an application ID and field name that contains the name of an alpha field containing the button reference name.
DISABLE statements are only valid in image-related event points.
