--
-- OBJECTIVE:
-- Check that actual parameters passed by reference are view converted
-- to the nominal subtype of the formal parameter.
--
-- TEST DESCRIPTION:
-- Check that sliding is allowed for formal parameters, especially
-- check cases that would have caused errors in Ada'83.
-- Check that length check for a formal parameter (esp out mode)
-- is performed before the call, not after.
--
-- notes: 6.2; by reference ::= tagged, task, protected,
-- limited (nonprivate), or composite containing such
-- 4.6; view conversion
--
--
-- CHANGE HISTORY:
-- 26 JAN 96 SAIC Initial version
-- 04 NOV 96 SAIC Commentary revision for release 2.1
-- 27 FEB 97 PWB.CTA Corrected reference to the wrong string
