** Modification History:
** 20-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
-** The debug mode will print all of the printfs associated with this test.

+** The debug mode will print all of the printfs associated with this test.
+** The regress mode will be the default mode. Since the regress tool limits
** the output to a one line status:PASS or FAIL,all of the printf statements
-** have been handled with an if (debug_mode) statement.
+** have been handled with an if (debug_mode) statement.
** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
-** recognize the return code from tha main program.
