By "type", Delphi actually means a type _name_. When using sets, you must 
declare a base type FIRST... besides, I think the whole type declaration is 
wrong - I'm surprised this made it to the book.
Try changing
 MJ> type
 MJ>   KeysType = set of [O..9, '*', '#'                          ];
                         (^ You have forgotten a ' here)
     const Key : set of char = ['0'..'9','*','#'];
 MJ>   Key       : KeysType;
Delete the above line.
Should work then.
