The following example uses DEFINE BAR to create items on menus. The current system menu bar is first saved to memory with SET SYSMENU SAVE, and then all system menu titles are removed with SET SYSMENU TO.
Two new system menu titles are created with DEFINE PAD, and DEFINE POPUP is used to create a drop-down menu for each menu title. DEFINE BAR is used to create items on each of the menus. When a menu title is chosen, ON PAD uses ACTIVATE POPUP to activate the corresponding menu.
When an item is chosen from a menu, ON SELECTION POPUP uses PROMPT( ) and POPUP( ) to pass the item number and menu name to the CHOICE procedure. CHOICE displays the prompt of the chosen item and the name of the menu containing the item. If Exit is chosen from the Card Info menu, the original Visual FoxPro system menu is restored.
