Modify_Topic


Purpose   To change all the settings of a menu topic.

Decln.    Modify_Topic(var
          M:Nest_Menu;TopicNo:word;N:MenuStr;A:Boolean;Key:char;code:intege
          r;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.
          N is the topic text, i.e. the string that will be displayed in
          the menu.
          A indicates if the topic is selectable or non-selectable. Set to
          true for normal selectable topics.
          Key is the character code of a hotkey that can be used to execute
          the topic. Set to #0 to disable the hotkey.
          Code is an integer code that will be passed to the despatcher
          procedure to indicate that the user selected this topic. Set the
          code to zero if a sub-menu is going to be called.
          Sub is the address of a sub-menu that is to be called if the
          topic is selected. Set to NIL if the topic executes a despatcher
          procedure rather than displaying a sub-menu.

Example

BEGIN
    MODIFY_TOPIC(BOBS_MENU,3,'FILE LOAD',TRUE,#166,300,NIL);
END;
