+-- OBJECTIVE:
+--      Check that the function To_Chars_Ptr will return a Null_Ptr value
+--      when the parameter Item is null.  If the parameter Item is not null,
+--      and references a chars_array object that does contain the char nul,
+--      and parameter Nul_Check is True, check that To_Chars_Ptr performs a
+--      pointer conversion from char_array_access type to chars_ptr type.
+--      Check that if parameter Item is not null, and references a
+--      chars_array object that does not contain nul, and parameter Nul_Check
+--      is True, the To_Chars_Ptr function will propagate Terminator_Error.
+--      Check that if parameter Item is not null, and parameter Nul_Check
+--      is False, check that To_Chars_Ptr performs a pointer conversion from
+--      char_array_access type to chars_ptr type.
+--
+--      Check that the New_Char_Array function will return a chars_ptr type
+--      pointer to an allocated object that has been initialized with
+--      the value of parameter Chars.
+--
+--      Check that the function New_String returns a chars_ptr initialized
+--      to a nul-terminated string having the value of the Str parameter.
+--
+-- TEST DESCRIPTION:
+--      This test uses a variety of of string, char_array,
+--      char_array_access and char_ptr values in order to validate the
+--      functions under test, and results are compared for both length
+--      and content.
+--
+--      This test assumes that the following characters are all included
+--      in the implementation defined type Interfaces.C.char:
+--      ' ', 'a'..'z', and 'A'.. 'Z'.
+--
+-- APPLICABILITY CRITERIA:
+--      This test is applicable to all implementations that provide
+--      package Interfaces.C.Strings.  If an implementation provides
+--      package Interfaces.C.Strings, this test must compile, execute, and
+--      report "PASSED".

+-- CHANGE HISTORY:
+--      20 Sep 95   SAIC    Initial prerelease version.
+--      09 May 96   SAIC    Incorporated reviewer comments for ACVC 2.1.
+--      01 DEC 97   EDS     Remove incorrect block of code (previously
+--                          lines 264-287)
+--      14 Sep 99   RLB     Added check for behavior of To_Chars_Ptr when
+--                          Nul_Check => False. (From Technical
+--                          Corrigendum 1).
