Parameters
- MenuBarName

- Command
- Specifies the command to execute when you choose a menu title. Use ONSELECTION MENU without a command to release a command assigned to a menu bar.
Remarks
When you create and activate a menu bar, place ON SELECTION MENU between DEFINE MENU and ACTIVATE MENU.
Use ON SELECTION PAD to execute a command when you choose a specific menu item. ON SELECTION PAD takes precedence over ON SELECTION MENU. Use ON PAD to activate a menu or menu bar when you choose a specific menu title.
Use ON SELECTION MENU without a command to release a command assigned to a menu bar.
Example
In the following example, ON SELECTION MENU is used to execute a procedure when a menu title is chosen from the Visual FoxPro system menu bar.
The current system menu bar is saved to memory with SET SYSMENU SAVE and all system menu titles are removed with SET SYSMENU TO.
DEFINE PAD creates several system menu titles. When you choose a menu title, the choice procedure assigned to the menu bar with ON SELECTION MENU executes. The choice procedure displays the name of the menu title you choose and the name of the menu bar. If you choose the Exit menu title, the original Visual FoxPro system menu is restored.
