+--*
+--
+-- OBJECTIVE:
+-- Check that function Length in the generic package Decimal_Output
+-- returns the number of characters in the edited output string
+-- produced by function Image, for a particular decimal type,
+-- currency string, and radix mark.
+-- Check that function Valid in the generic package Decimal_Output
+-- returns correct results based on the particular decimal value,
+-- and the Picture and Currency string parameters.
+--
+-- TEST DESCRIPTION:
+-- This test uses two instantiations of package Decimal_Output, one
+-- for decimal data with delta 0.01, the other for decimal data with
+-- delta 1.0. The functions Length and Valid found in this generic
+-- package are evaluated for each instantiation.
+-- Function Length is examined with picture and currency string input
+-- parameters of different sizes.
+-- Function Valid is examined with a decimal type data item, picture
+-- object, and currency string, for cases that are both valid and
+-- invalid (Layout_Error would result from the particular items as
+-- input parameters to function Image).
+--
+-- TEST FILES:
+-- The following files comprise this test:
+--
+-- FXF3A00.A (foundation code)
+-- => CXF3A03.A
