10 ** Description: Join kernel - user
11 **
12 ** Modification History:
13 **
14 ** 19-May-97 AGarcia - separate the four join tests into different unit test modules.
15 ** AGarcia- Converted the test to accomodate the debug_mode flag.
16 ** The debug mode will print all of the printfs associated with this test.
17 ** The regress mode will be the default mode. Since the regress tool limits
18 ** the output to a one line status:PASS or FAIL,all of the printf statements
19 ** have been handled with an if (debug_mode) statement.
20 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
21 ** recognize the return code from tha main program.
