--

-- 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).

--
