These -- visible and private generic packages are instantiated in the body of -- the public child and the private child, respectively. -- The main program utilizes the functions declared in the public child -- to verify results of the instantiations. -- -- Inspired by B74103F.ADA. -- -- -- CHANGE HISTORY: -- 12 Mar 96 SAIC Initial version for ACVC 2.1. -- 05 Oct 96 SAIC ACVC 2.1: Added pragma Elaborate for CDE0001. -- 21 Nov 98 RLB Added pragma Elaborate for CDE0001 to CDE0001_3. --! package CDE0001_0 is subtype Small_Int is Integer range 1 .. 2;
