CONST, TYPE, VAR

     The following are globally declared in the ListTTT5 unit:

     CONST
         MAX_TOPICS = 255
     TYPE
         CHOICES = ARRAY[1..MAX_TOPICS] OF BOOLEAN;
         LIST_HOOK = PROCEDURE(VAR CH:CHAR; HIPICK:BYTE); {VER 5.0}
     VAR
        LTTT      : L_DISPLAY;
        L_PICKS   : CHOICES;
        L_CHAR    : CHAR;
        L_PICK    : BYTE;
        L_USERHOOK: POINTER {VER 4.0}


     Max_Topics - the maximum number of topics that can be displayed in a
     list. It can be changed to any value in the range 2..255. The memory
     saving is not significant and so modification is not recommended.
