>vfp gives you this array (i can't remember the name -- i'll look it up later if no one else responds). we use this array in the manner you're suggesting. with properties added to textboxes, we determine which fields require data entry. when attempting to save info and exit the form, we call one method which reads through this array and generates a list of data items that require entry but were left blank. if any meet this requirement, this info is stored in an array in this method. the user can only exit and save when this array is empty.
