-- 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.
