Check for cases of records. -- -- 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. -- -- Inspired by C37213A.ADA, C37213C.ADA, C37215A.ADA and C37215C.ADA. -- -- -- CHANGE HISTORY: -- 05 Apr 96 SAIC Initial version for ACVC 2.1. -- --! with Report; procedure C371002 is subtype Small_Int is Integer range 1..10; type Rec_W_Disc (Disc1, Disc2 : Small_Int) is record Str1 : String (1 ..
