-- FOUNDATION DESCRIPTION:
-- This foundation declares various volatile and non-volatile types. Some
-- are by-reference types, and some allow pass-by-copy.
--
-- CHANGE HISTORY:
-- 23 Jan 96 SAIC Initial version for ACVC 2.1.
-- 02 DEC 97 EDS Removed Pragma Volatile applied to composite types.
-- 27 AUG 99 RLB Repaired so Nonvolatile_Tagged really is
-- Nonvolatile.
--!
package FXC6A00 is
type Roman is ('I', 'V', 'X', 'L', 'C', 'D', 'M'); -- By-copy type.
type Acc_Roman is access all Roman;
type Tagged_Type is tagged record -- By-reference type.

type Volatile_Tagged is new Tagged_Type with record -- Volatile by-reference
R1: Roman; -- type.
end record;

type Acc_Volatile_Tagged is access all Volatile_Tagged;
-- By-reference type.
type NonVolatile_Tagged is new Tagged_Type with record
R2: aliased Roman;
end record;
task type Task_Type is -- By-reference type.
entry Calculate (C: in out Natural);
end Task_Type;
type Acc_Task_Type is access all Task_Type;

end Volatile_Protected;
pragma Volatile (Volatile_Protected);
type Acc_Vol_Protected is access all Volatile_Protected;
type Record_Type is record -- Allows pass-by-copy.
C: String(1 .. 2);
end record;
type Volatile_Record is limited record -- Volatile by-reference
C: String(1 .. 2); -- type.
end record;
pragma Volatile (Volatile_Record);
type Composite_Type is record -- By-reference type.
C: Tagged_Type;
D: aliased Volatile_Tagged; -- Volatile component.
end record;
type Private_Type is private; -- By-reference type.
type Array_Type is array (1..3) of Tagged_Type; -- By-reference type.
pragma Volatile_Components (Array_Type);
type Acc_Array_Type is access all Array_Type;
type Lim_Private_Type is limited private; -- By-copy type.
