Description

This example defines four pushbuttons on a selection screen that is displayed as a dialog box. The selection screen is defined in a chained statement for the keyword SELECTION-SCREEN.

“CLI1", "CLI2", "CLI3", and "CLI4" are used for fcode. If the user chooses a pushbutton, the runtime environment triggers the AT SELECTION-SCREEN event. The program is resumed after CALL SELECTION-SCREEN only if the user chooses Execute.
