READ MENU is included for backward compatibility. Use the FoxPro Menu Builder to create menus.

This command activates the menu popup created with @ ... MENU.

The value initially contained in the memory variable or array element memvar specifies which popup option is selected when the popup is activated. When you choose a popup option, a value is stored to memvar corresponding to the option you choose. If you press Esc to exit the popup, memvar contains 0.

SAVE
 The SAVE clause keeps an image of the menu popup in the main FoxPro window or in a user-defined window after a choice is made from the menu or Esc is pressed. Normally, the menu is cleared from the main FoxPro window or a user-defined window after you make a choice.
