--
-- OBJECTIVE:
--      Check that if a discriminant constraint depends on a discriminant,
--      the evaluation of the expressions in the constraint is deferred 
--      until an object of the subtype is created.  Check for cases of 
--      records where the component containing the constraint is present
--      in the subtype.                                                    
--
-- TEST DESCRIPTION:
--      This transition test defines record types with discriminant components
--      which depend on the discriminants.  The discriminants are calculated 
--      by function calls.  The test verifies that Constraint_Error is raised 
--      during the object creations when values of discriminants are 
--      incompatible with the subtypes.  Also check for cases, where the
--      component is absent.
--
--      Inspired by C37213E.ADA, C37213G.ADA, C37215E.ADA, and C37215G.ADA.

--
-- CHANGE HISTORY:
--      10 Apr 96   SAIC    Initial version for ACVC 2.1.
--      14 Jul 96   SAIC    Modified test description.  Added exception handler
--                          for VObj_10 assignment.
--      26 Oct 96   SAIC    Added LM references.
