Return and Reason Codes

When the IWMSCXIT 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.
