A call to the "previous definition" of a method.
E.g.

A = OBJECT
      PROCEDURE Do;
      BEGIN END Do;
END A;

B = OBJECT(A)
     PROCEDURE Do; (* overrides procedure Do *)
     BEGIN
         (* Do; (* would be a recursive call of Do *) *)
         Do^; (* re-uses the previous definition of Do in the "super
object class" (A in this case) and is called a supercall *)
END B;
