 An Integer.T is an INTEGER.  This interface is intended to be
   used to instantiate generic interfaces and modules such as Table
   and List. 


INTERFACE Integer;

IMPORT Word;

TYPE T = INTEGER;

CONST Brand = "Integer";

PROCEDURE Equal(a, b: T): BOOLEAN;

 Return a = b. 

PROCEDURE Hash(a: T): Word.T;

 Return a. 

PROCEDURE Compare(a, b: T): [-1..1];

 Return -1 if a < b, 0 if a = b, or +1 if a > b. 

END Integer.
