trying to work with generic

["Cephus�" <beau@hiwaay.net>]

Hello guys, I am getting an error here trying to compile a specification for
an array_generic package I am making for class. Can you guys tell me why it
is not allowing me to use (<>) in the indextype declaration:

WITH Ada.TEXT_IO;

GENERIC


PACKAGE array_generic IS


--declare the private type

TYPE elementType IS PRIVATE;


--declare the index type, the generic array

TYPE indexType IS (<>);

TYPE listType IS ARRAY(indexType RANGE <>) OF elementType;


PROCEDURE getData(list : OUT listType; infile : IN OUT

Ada.TEXT_IO.File_Type);


PROCEDURE Display(list : IN listType);


FUNCTION Find(list : listType; item : elementType) RETURN Boolean;


end array_generic;
