--

-- OBJECTIVE:

--      Check that statically identifiable picture strings can be used

--      in conjunction with function Image to produce output strings

--      appropriate to foreign currency representations.

--

--      Check that statically identifiable picture strings will cause

--      function Image to raise Layout_Error under the appropriate

--      conditions.

--

-- TEST DESCRIPTION:

--      This test defines several picture strings that are statically

--      identifiable, (i.e.,  Pic : Picture := To_Picture("..."); ).

--      These picture strings are used in conjunction with decimal data

--      as parameters in calls to function Image.

--

--

-- CHANGE HISTORY:

--      11 Apr 96   SAIC    Initial release for 2.1.
