+-- These rights include rights to use, duplicate, release or disclose the

+--*
+--
+-- OBJECTIVE:
+-- Check that the subprograms defined in package Ada.Strings.Fixed are
+-- available, and that they produce correct results. Specifically,
+-- check the subprograms Index, Index_Non_Blank, Head, Tail, Translate,
+-- Find_Token, Move, Overwrite, and Replace_Slice.
+--
+-- TEST DESCRIPTION:
+-- This test demonstrates how certain fixed string operations could be
+-- used in string information processing. A procedure is defined that
+-- will extract portions of a 50 character string that correspond to
+-- certain data items (i.e., name, address, state, zip code). These
+-- parsed items will then be added to the appropriate fields of data
+-- base elements. These data base elements are then compared for
+-- accuracy against a similar set of predefined data base elements.
+--
+-- A variety of fixed string processing subprograms are used in this
+-- test. Each parsing operation uses a different combination
+-- of the available subprograms to accomplish the same goal, therefore
+-- continuity of approach to string parsing is not seen in this test.
+-- However, a wide variety of possible approaches are demonstrated, while
+-- exercising a large number of the total predefined subprograms of
+-- package Ada.Strings.Fixed.
