+/***********************************************************************
+**
+** Name: select2.c
+**
+** Description: Measure PR_Select and Empty_Select performance.
+**
+** 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 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.
