I have a dbForm (VDF11.1) displaying a SSN. The field has a mask
defined in the DD. When the field contains a non-numeric character the
display is blank - just as if the field IS BLANK!

This is confusing to the clerk who got an error message when the record
(as a parent) was being updated when the child record was saved.

Is this correct behavior? Shouldn't the field have displayed something?

I guess I need to augment the error message to display the contents of
the field.
