Exit-specific parameters
UEPSYSRC
Address of the 4-byte return code from the SYSEVENT request
made before the operating system wait. This return code will be in
one of two different forms:
1. The SYSEVENT OKSWAP return code, or
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.

DL/I interface program exits XDLIPRE and XDLIPOST
The XDLIPRE and XDLIPOST exit points are invoked following the issue of an
EXEC DLI command or DL/I call. Exit XDLIPRE is invoked before the request is
processed and XDLIPOST is invoked after the request is processed.
When the request is function shipped, the exits are invoked from both the
application-owning region and the database-owning region. However, there are
restrictions when they are invoked in a database-owning region, as described
below.
The CICS IMS Database Control Guide contains a sample program for the
XDLIPRE exit.
