Description

The ON SELECTION BAR command defines a command that will be executed when the specified menu bar is selected. A menu bar is a selection option in dBASE-IV style pop-up menus. Pop-up menus of this type are created with the DEFINE POPUP and DEFINE BAR commands. The bar is identified by the numeric expression <expN> that was assigned with the DEFINE BAR command. The pop-up is identified by its name which was assigned with the DEFINE POPUP command. The command SET COMPATIBLE should be ON when using dBASE IV style menus.
