+--*
+--
+-- OBJECTIVE:
+--      Check that the function Valid with Packed_Decimal and Packed_Format
+--      parameters returns True if Item (the Packed_Decimal parameter) has
+--      a value consistent with the Packed_Format parameter.
+--
+--      Check that the function Length with Packed_Format parameter returns
+--      the minimal length of a Packed_Decimal value sufficient to hold any
+--      value of type Num when represented according to parameter Format.
+--
+--      Check that the function To_Decimal with Packed_Decimal and 
+--      Packed_Format parameters produces a decimal type value corresponding 
+--      to the Packed_Decimal parameter value Item, under the conditions of 
+--      the Packed_Format parameter Format.
+--
+--      Check that the function To_Packed with Decimal (Num) and 
+--      Packed_Format parameters produces a Packed_Decimal result that 
+--      corresponds to the decimal parameter under conditions of the 
+--      Packed_Format parameter.
+--
+--      Check that Conversion_Error is propagated by function To_Packed if 
+--      the value of the decimal parameter Item is negative and the specified
+--      Packed_Format parameter is Packed_Unsigned.
+--
+--      
+-- TEST DESCRIPTION:
+--      This test checks the results from instantiated versions of 
+--      several functions that deal with parameters or results of type
+--      Packed_Decimal.  Since the rules for the formation of Packed_Decimal
+--      values are implementation defined, several of the subtests cannot
+--      directly check the accuracy of the results produced. Instead, they
+--      verify that the result is within a range of possible values, or
+--      that the result of one function can be converted back to the original 
+--      actual parameter using a "mirror image" conversion function.
+--      
+-- 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".
