FLUSH removes the menu and its associated windows from memory. If the menu is displayed on the screen, the FLUSH statement/command also erases the menu from the screen.
After a FLUSH, the menu ID is removed and is not available. FLUSH menu ID should be executed for each menu if it is no longer needed. This will save memory space used by the process.
