-- OBJECTIVE:
--      Check that if different forms of a name are used in the default 
--      expression of a discriminant part, the selector may be an operator
--      symbol or a character literal.
--
-- TEST DESCRIPTION:
--      This transition test defines private types where their selectors in
--      the default expression of the discriminant parts at the full type 
--      declarations are an operator and a literal, respectively. 
--      The test also declares procedures that use an operator and a literal
--      as selectors in the formal parts. 
--
--      Inspired by B63102A.ADA.

-- CHANGE HISTORY:
--      25 Mar 96   SAIC    Initial version for ACVC 2.1.
--      26 Feb 97   PWB.CTA Removed use of function called before elaboration
