The Implement of Menu Item's Sleep and Internal Driving In FoxBase+

Use @...PROMPT and MENU TO statement in FoxBase+, and we can establish a (color) bright menu in screen. From the menu, we can press cursor key to choice a menu item, and press ENTER to select it and run its route. But when some menu item should be disabled, we must let it into "sleep" state. Additionally, if it is necessary to execute another function belonging to another menu item while a menu item's running, we refer to driving internally the corresponding menu item, rather than to running directly on its route. It is discussed the advantage of both the two techniques and their realization are discussed on the paper.
