+/***********************************************************************
+**
+** Name: fileio.c
+**
+** Description: Program to copy one file to another. 
+**
+** Modification History:
+** 14-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.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
+** 12-June-97 Revert to return code 0 and 1, remove debug option (obsolete).
