It demonstrates -- the use of these types and functions as they would be used in common -- programming practice. -- Wide_Character set creation, assignment, and comparison are evaluated -- in this test. Each of the functions provided in package -- Ada.Strings.Wide_Maps is utilized in creating or manipulating set -- objects, and the function results are evaluated for correctness. -- Wide_Character sequences are examined using the functions provided for -- manipulating objects of this type. Likewise, Wide_Character maps are -- created, and their contents evaluated. Exception raising conditions -- from the function To_Mapping are also created. -- Note: Throughout this test, the set logical operators are printed in -- capital letters to enhance their visibility. -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- 01 Nov 95 SAIC Update and repair for ACVC 2.0.1. -- --! with Ada.Characters.Handling; with Ada.Strings.Wide_Maps; package CXA40120 is function Equiv (Ch : Character) return Wide_Character; function Equiv (Str : String) return Ada.Strings.Wide_Maps.Wide_Character_Sequence; function X_Map(From : Wide_Character) return Wide_Character; end CXA40120; package body CXA40120 is -- The following two functions are used to translate character and string -- values to "Wide" values.
