Return and Reason Codes

When the IWM4MDRG 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.

Table 76. Return and Reason Codes for the IWM4MDRG Macro
Return Code	Reason Code	Equate Symbol, Meaning, and Action
0	—	Equate Symbol: IwmRetCodeOk Meaning: Successful completion. Action: None required.
4	—	Equate Symbol: IwmRetCodeWarning Meaning: Successful completion, unusual conditions noted.
4	xxxx041D	Equate Symbol: IwmRsnCodeBadResTkn Meaning: The input resource token is not valid. The system may have deregistered due to errors associated with an exit. Action: Verify that the resource token passed has the intended value.
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: The 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	xxxx0823	Equate Symbol: IwmRsnCodeDatoff Meaning: The caller invoked the service while DATOFF Action: Avoid requesting this function in this environment.
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 or in 64-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	xxxx082F	Equate Symbol: IwmRsnCodeWrongHome Meaning: The caller invoked the service from the wrong home space. Action: Invoke the service from the owning address space.
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.
