SYMPTOMS
Contrary to expectation, the TAB key does not trigger a list box's VALID clause.



CAUSE
Unlike most screen GET objects, in order for its VALID clause to be executed, a list box requires a selection be made with a press of the ENTER key or a double-click of the mouse. Even though positioning the highlight bar on a particular entry in a list box and pressing the TAB key updates the list-box variable's value, the VALID clause is ignored.



STATUS
This behavior is by design.
