= DEF CHECKONEITEM Statement =

Statement
✔ Appearance ✔ Standard ✔ Console

Description
Places a checkmark next to the specified item in the specified menu, and unchecks all other items in that menu. The menu ID number is assigned by the  statement, or by a Toolbox routine that creates the menu, or by the resource that defines the menu. The item ID corresponds to the item's position in the menu (the item just under the menu title is item #1). Note that gray "dividing lines" in menus are also counted as menu items.

Use an  value of zero to uncheck all items in the menu.

Note
Do not set  to a menu item which has a hierarchical submenu attached to it.
