-- OBJECTIVE:
--     CHECK THAT, FOR OUT PARAMETERS OF AN ACCESS TYPE,
--     CONSTRAINT_ERROR IS RAISED:
--          AFTER A SUBPROGRAM CALL WHEN THE BOUNDS OR DISCRIMINANTS
--          OF THE FORMAL DESIGNATED PARAMETER ARE DIFFERENT FROM
--          THOSE OF THE ACTUAL DESIGNATED PARAMETER.
 
-- HISTORY:
--     CPP  07/23/84  CREATED ORIGINAL TEST.
--     VCL  10/27/87  MODIFIED THIS HEADER; ADDED STATEMENTS WHICH
--                    REFERENCE THE ACTUAL PARAMETERS.
