8.7 Menu Input

Menu selections are handled by the ACCEPT statement. Generally speaking, a menu selection acts much like a function key. Each menu item causes an ACCEPT statement to terminate, returning an exception value equal to the item's ID.

For example, suppose the menu has this definition: 

menu main-menu

   "&File", 0,  submenu

          "&New", 101

          "&Open", 102

          "&Save", 103

          "Save &As...", 104

          separator

          "E&xit", 105

          end-menu



     "&Options", 0,  submenu

          "&Save Settings on Exit", 201, checked

          "&Password Protect",  202, checked

          "&Confirm Deletions",  203

          end-menu

If the user selected the "New" menu item, then any executing ACCEPT statement would terminate with an exception status of "101".

Important: Note that only ACCEPT statements that allow exception keys will terminate with a menu selection. If the ACCEPT statement does not allow exceptions, any menu selections will be ignored.
