Return and Reason Codes

When the IWM4SSM 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 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: Caller is in SRB mode. Action: Avoid requesting this function while 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	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 in primary ASC mode. Action: Avoid requesting this function in this environment.
8	xxxx0827	Equate Symbol: IwmRsnCodeRsvdNot0 Meaning: Reserved field in parameter list was not zero. Action: Check for use of keywords that are not supported by the MVS™ release on which the program is running.
8	xxxx0828	Equate Symbol: IwmRsnCodeBadVersion Meaning: Version number in parameter list is not valid. Action: Check for possible storage overlay of the parameter list.
8	xxxx0840	Equate Symbol: IwmRsnCodeServiceNotEnabled Meaning: The caller's space connection is not enabled for this service Action: Make sure that SERVER_MANAGER=YES is specified on the IWM4CON request to enable this service.
8	xxxx0841	Equate Symbol: IwmRsnCodeXmemMode Meaning: The caller is in cross-memory mode. Action: Request this function only when you are not in cross-memory mode.
8	xxxx0842	Equate Symbol: IwmRsnCodeNoWLMConnect Meaning: The caller's space is not connected to WLM. Action: Invoke the IWM4CON macro before invoking this macro.
8	xxxx0862	Equate Symbol: IwmRsnCodeNoPriorSelect Meaning: The caller has not previously selected work using the IWM4SSL macro. Action: Invoke the IWM4SSL macro before invoking this macro.
8	xxxx0863	Equate Symbol: IwmRsnCodeNoExecEnv Meaning: The caller has not established an execution environment using IWM4STBG. Action: Invoke the IWM4STBG macro before invoking this macro.
C	—	Equate Symbol: IwmRetCodeEnvError Meaning: Environmental error.
C	xxxx0C14	Equate Symbol: IwmRsnCodeNoWorkShutDown Meaning: No work selected. Caller is to shutdown. Action: The caller must disconnect by invoking the IW DISC macro.
