+-- OBJECTIVE:
+--      Check that the function Valid with Byte_Array and Binary_Format 
+--      parameters returns True if the Byte_Array parameter corresponds 
+--      to any value inside the range of type Num.
+--      Check that function Valid returns False if the Byte_Array parameter
+--      corresponds to a value outside the range of Num. 
+--
+--      Check that function Length with Binary_Format parameter will return
+--      the minimum length of a Byte_Array value required to hold any value
+--      of decimal type Num.
+--
+--      Check that function To_Decimal with Byte_Array and Binary_Format
+--      parameters will return a decimal type value that corresponds to
+--      parameter Item (of type Byte_Array) under the specified Format.
+--
+--      Check that Conversion_Error is propagated by function To_Decimal if
+--      the Byte_Array parameter Item represents a decimal value outside the
+--      range of decimal type Num.
+--
+--      Check that function To_Binary will produce a Byte_Array result that
+--      corresponds to the decimal type parameter Item, under the specified
+--      Binary_Format.
+--      
+-- TEST DESCRIPTION:
+--      This test uses several instantiations of generic package 
+--      Decimal_Conversions to provide appropriate test material.
+--      This test uses the function To_Binary to create all Byte_Array 
+--      parameter values used in calls to functions Valid and To_Decimal.
+--      The function Valid is tested with parameters to provide both
+--      valid and invalid expected results.  This test also checks that
+--      Function To_Decimal produces expected results in cases where each
+--      of the three predefined Binary_Format constants are used in the
+--      function calls. In addition, the prescribed propagation of 
+--      Conversion_Error by function To_Decimal is verified.
+--      
+-- 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".
