Enumerations, lists or character name arrays

The PopupCodes enumeration lists the possible ``special'' return codes for the menu items. Items in a menu with a return code greater than zero are items which when selected result in some command being executed. Items in a menu with one of the following return codes (which are all ) are special menu items:

• MENU_CODE_NONE: Indicates the item does not do anything, it is just a label or a placeholder.
• MENU_CODE_SEP: The item is a separator, which means that a separating line should be drawn (if possible) between the items preceing and following this item.
• MENU_CODE_SUBMENU: The item contains a submenu, so it does not do any action itself, but provides access to a lower level of items.
