---
--- OBJECTIVE:
--- Check that Ada.Strings.Bounded procedures Append, Head, Tail, and
--- Trim, and relational operator functions "=", ">", ">=", "<", "<="
--- with parameter combinations of type String and Bounded_String,
--- produce correct results.
---
--- TEST DESCRIPTION:
--- This test examines the operation of several subprograms from within
--- the Ada.Strings.Bounded package. Four different instantiations of
--- Ada.Strings.Bounded.Generic_Bounded_Length provide packages defined
--- to manipulate bounded strings of lengths 1, 20, 40, and 80.
--- Examples of the above mentioned procedures and relational operators
--- from each of these instantiations are tested, with results compared
--- against expected output.
---
--- Testing of the function versions of many of the subprograms tested
--- here is performed in tests CXA4006-CXA4009.
---
---
--- CHANGE HISTORY:
--- 16 Feb 95 SAIC Initial prerelease version
--- 10 Mar 95 SAIC Incorporated reviewer comments.
--- 15 Apr 96 SAIC Incorporated reviewer comments for ACVC 2.1.
