Return codes for the initialization and termination exits

Table 1 shows the return codes that the PARMLIB initialization and termination exits support.

Table 1. Return codes for the PARMLIB initialization and termination exits
Return code (decimal)	Description
0	Exit processing was successful. PARMLIB processing continues.
12	Exit processing was unsuccessful. PARMLIB issues an error message to the user and then terminates processing. The error message identifies the exit that requested termination and a reason code. For more information about the exit reason code, see Exit reason code.
16	Exit processing was unsuccessful. PARMLIB terminates processing without issuing an error message to the user. Before the exit returns with return code 16, it can display a message to the user, for example, using PUTLINE.

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