Modify_Topic_Submenu
Purpose Modifies the Topic pointer to a sub-menu.
Decln. Modify_Topic_SubMenu(var M:Nest_Menu;TopicNo:word;Sub:MenuPtr);
Remarks M is the name of the menu variable that contains the topic.
TopicNo is the number of the topic to be modified.
Sub is the address of a sub-menu that is to be called if the
topic is selected. Use the '@' argument to pass the address of a
menu, e.g. @Print_menu. Set to NIL if the topic executes a
despatcher procedure rather than displaying a sub-menu.
Example
BEGIN
MODIFY_TOPIC_SUBMENU(BOBS_MENU,3,@FILE_MENU);
END;
