DEACTIVATE MENU Command Example

The following example uses DEACTIVATE MENU to deactivate a menu and remove it from the screen. The current system menu bar is saved to memory with SET SYSMENU SAVE, and all the system menu titles are removed with SET SYSMENU TO.

Two menu titles are created with DEFINE PAD, and DEFINE POPUP creates a menu for each menu title. DEFINE BAR creates menu items on each of the menus. When a menu title is chosen, ON PAD uses ACTIVATE POPUP to activate the corresponding menu. ACTIVATE MENU displays and activates the menu bar.

When an item is chosen from a menu, the CHOICE procedure is executed. CHOICE displays the name of the chosen item and the name of the menu containing the item. Program control continues on the line after ACTIVATE MENU.

Finally, the menu is deactivated and removed from the screen and is then released from memory with RELEASE MENUS EXTENDED.
