  2. If the SYSEVENT request was rejected by CICS, a special CICS return code which will take one of the following decimal values:
    17
    The SYSEVENT OKSWAP was not issued. The outstanding count of SYSEVENT OKSWAP requests exceeds the count of SYSEVENT DONTSWAP requests. Before a SYSEVENT OKSWAP can be issued, a SYSEVENT DONTSWAP must be requested.
    19
    The SYSEVENT OKSWAP was not issued. The outstanding count of SYSEVENT DONTSWAP requests still exceeds the count of SYSEVENT OKSWAPs. Further SYSEVENT OKSWAPs must be requested before a SYSEVENT OKSWAP is issued by CICS.
