Return and Reason Codes

When the IWM4MREG 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.

Return Code	Reason Code	Equate Symbol, Meaning, and Action
0	—	Equate Symbol: IwmRetCodeOk Meaning: Successful completion. Action: None required.
8	—	Equate Symbol: IwmRetCodeInvocError Meaning: Invalid invocation environment or parameters.
8	xxxx0801	Equate Symbol: IwmRsnCodeSRBMode Meaning: The caller is in SRB mode. Action: Avoid requesting this function in SRB mode.
8	xxxx0803	Equate Symbol: IwmRsnCodeDisabled Meaning: Caller is disabled. Action: Avoid requesting this function while disabled.
8	xxxx0804	Equate Symbol: IwmRsnCodeLocked Meaning: Caller is locked. Action: Avoid requesting this function while locked.
8	xxxx080B	Equate Symbol: IwmRsnCodeBadPl Meaning: Error accessing parameter list. Action: Check for possible storage overlay.
8	xxxx0810	Equate Symbol: IwmRsnCodeEutFrr Meaning: The caller has EUT FRR established. Action: Avoid requesting this function with an EUT FRR.

8	xxxx0824	Equate Symbol: IwmRsnCodeAmode24 Meaning: The caller invoked the service but was in 24-bit addressing mode. Action: Request this function only when you are in 31-bit addressing mode.
8	xxxx0825	Equate Symbol: IwmRsnCodeAscModeNotPrimary Meaning: The caller invoked the service but was not DAT on Primary ASC mode. Action: Avoid requesting this function in this environment.
8	xxxx0828	Equate Symbol: IwmRsnCodeBadVersion Meaning: Version number or version length field in parameter list is not valid. Action: Check for possible overlay of the parameter list.
8	xxxx0841	Equate Symbol: IwmRsnCodeXmemMode Meaning: The caller invoked the service but was in cross-memory mode. Action: Avoid requesting this function in cross-memory mode.
8	xxxx0846	Equate Symbol: IwmRsnCodeNoUserKeyReg Meaning: The caller invoked the service but was in user key. Action: Request this function in system key (0-7).
8	xxxx08A1	Equate Symbol: IwmRsnCodeBadBPMinMaxSize Meaning: Maximum resource size is lower than the minimum size. Action: Specify a maximum size value at least as high as the minimum size value.
C	xxxx0C01	Equate Symbol: IwmRetCodeEnvError: Meaning: Environmental error. Action: Storage is not available for the request.
10	—	Equate Symbol: IwmRetCodeCompError Meaning: Component error. Action: Contact your system programmer.
