-- OBJECTIVE:
-- CHECK THAT A DERIVED TYPE DECLARATION AND A GENERIC
-- INSTANTIATION MAY DERIVE TWO OR MORE SUBPROGRAM HOMOGRAPHS.
-- CHECK THE CASES WHERE:
-- 1) THE DERIVED SUBPROGRAMS BECOME HOMOGRAPHS BECAUSE OF THE
-- SUBSTITUTION OF THE DERIVED TYPE FOR THE PARENT TYPE IN
-- THE IMPLICIT SUBPROGRAM SPECIFICATIONS.
-- 2) THE PARENT TYPE IS DECLARED IN A GENERIC INSTANCE AND
-- THE INSTANCE INCLUDES TWO OR MORE DERIVABLE SUBPROGRAMS
-- THAT ARE HOMOGRAPHS AS A RESULT OF THE ARGUMENTS GIVEN
-- FOR THE GENERIC FORMAL-TYPE PARAMETERS.
-- TEST CASES WHERE THE DERIVED TYPE DECLARATIONS AND GENERIC
-- INSTANTIATIONS ARE GIVEN IN:
-- . THE VISIBLE PART OF A PACKAGE SPECIFICATION,
-- . THE PRIVATE PART OF A PACKAGE SPECIFICATION,
-- . A PACKAGE BODY,
-- . A SUBPROGRAM BODY,
-- . A BLOCK STATEMENT.

-- HISTORY:
-- VCL 03-08-88 CREATED ORIGINAL TEST.
