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. -- --! with Report; procedure C371003 is subtype Small_Int is Integer range 1..10; type Rec_W_Disc (Disc1, Disc2 : Small_Int) is record Str1 : String (1 ..
