-- OBJECTIVE:
--      Check that function Valid, with the Display_Format parameter 
--      set to Unsigned, will return True if Numeric parameter Item 
--      comprises one or more decimal digit characters; check that it 
--      returns False if the parameter Item is otherwise comprised.
--
--      Check that function Valid, with Display_Format parameter set to 
--      Leading_Separate, will return True if Numeric parameter Item 
--      comprises a single occurrence of a Plus_Sign or Minus_Sign 
--      character, and then by one or more decimal digit characters; 
--      check that it returns False if the parameter Item is otherwise 
--      comprised.
--
--      Check that function Valid, with Display_Format parameter set to 
--      Trailing_Separate, will return True if Numeric parameter Item 
--      comprises one or more decimal digit characters, and then by a 
--      single occurrence of the Plus_Sign or Minus_Sign character; 
--      check that it returns False if the parameter Item is otherwise
--      comprised.
--
-- TEST DESCRIPTION:
--      This test checks that a version of function Valid, from an instance
--      of the generic package Decimal_Conversions, will produce correct
--      results based on the particular Numeric and Display_Format
--      parameters provided.  Arrays of both valid and invalid Numeric
--      data items have been created to correspond to a particular
--      value of Display_Format.  The result of the function is compared
--      against the expected result for each appropriate combination of
--      Numeric and Display_Format parameter.
--      This test assumes that the following characters are all included
--      in the implementation defined type Interfaces.COBOL.COBOL_Character:
--      ' ', 'A'..'Z', '+', '-', '.', '$'.
--      
-- APPLICABILITY CRITERIA: 
--      This test is applicable to all implementations that provide 
--      package Interfaces.COBOL.  If an implementation provides
--      package Interfaces.COBOL, this test must compile, execute, and 
--      report "PASSED".
