+--
+-- OBJECTIVE:
+--      Check that the Function To_Fortran with a Character parameter will
+--      return the corresponding Fortran Character_Set value.
+--
+--      Check that the Function To_Ada with a Character_Set parameter will 
+--      return the corresponding Ada Character value.
+--
+--      Check that the Function To_Fortran with a String parameter will
+--      return the corresponding Fortran_Character value.
+--
+--      Check that the Function To_Ada with a Fortran_Character parameter
+--      will return the corresponding Ada String value.
+--
+-- TEST DESCRIPTION:
+--      This test checks that the functions To_Fortran and To_Ada produce
+--      the correct results, based on a variety of parameter input values.
+--      
+--      In the first series of subtests, the results of the function
+--      To_Fortran are compared against expected Character_Set type results.
+--      In the second series of subtests, the results of the function To_Ada
+--      are compared against expected String type results, and the length of
+--      the String result is also verified against the Fortran_Character type
+--      parameter.
+--      
+--      This test uses Fixed, Bounded, and Unbounded_Strings in combination
+--      with the functions under validation.
+--      
+--      This test assumes that the following characters are all included
+--      in the implementation defined type Interfaces.Fortran.Character_Set:
+--      ' ', 'a'..'z', 'A'..'Z', '1'..'9', '-', '_', '$', '#', and '*'.
+--      
+-- APPLICABILITY CRITERIA: 
+--      This test is applicable to all implementations that provide 
+--      package Interfaces.Fortran.  If an implementation provides
+--      package Interfaces.Fortran, this test must compile, execute, and 
+--      report "PASSED".
+--
+--      This test does not apply to an implementation in which the Fortran
+--      character set ranges are not contiguous (e.g., EBCDIC).
+--
