Return and Reason Codes
When the IWM4MCHS macro returns control to your program:
- GPR 15 (and retcode, when you code RETCODE) contains
a return code.
- When the value in GPR 15 is not zero, GPR 0 (and rsncode,
when you code RSNCODE) contains a 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.
