Return codes for IKJEFLN1

Table 1 shows the return codes that IKJEFLN1 supports.

Table 1. Return codes for logon exit IKJEFLN1
Return code (decimal)	Description
0	Exit processing was successful. Logon processing continues.
12	Exit processing was unsuccessful. The logon processor issues an error message to the user and the console and then terminates processing. If the exit uses return code 12, it can also pass back an exit reason code to the LOGON command processor. For more information about the exit reason code, see Exit reason code.
16	Exit processing was unsuccessful. The logon processor terminates processing. The LOGON command processor does not display a message to the user or console if the exit sets a return code of 16. Before the exit returns with return code 16, it can display a message to the user, for example, using PUTLINE.

Note: If this exit issues return code 12 or 16, the post-display exit (IKJEFLN2) gets control. If you do not want the post-display exit (IKJEFLN2) to get control when IKJEFLN1 issues a return code of 12 or 16, then IKJEFLN1 should set the don't prompt bit on and the invoking of IKJEFLN2 should be turned off.

If the exit returns an undefined return code, the LOGON command processor terminates without displaying a message.
