Return and Reason Codes

When the IWMSRSRG macro returns control to your program:

GPR 15 (and retcode, if you coded RETCODE) contains a return code.
When the value in GPR 15 is not zero, GPR 0 (and rsncode, if you coded RSNCODE) contains reason code.

The following table identifies the hexadecimal return and reason codes and the equate symbol associated with each reason code. IBM® support personnel may request the entire reason code, including the xxxx value.
