UEPCLPS exit-specific parameter” on page 240.

allows you, for example, to pass a work area to exit XTDEREQC.

‘EIBRCODE’. For details of EIB return codes, refer to EIB fields, in
the CICS Application Programming Reference manual.

when the exit is first invoked, and is incremented for each recursive

EIBRSRCE.
Return codes
UERCNORM
Continue processing.
UERCBYP
The transient data EXEC interface program should ignore this
request.
UERCPURG

XPI calls
All can be used.
Although the exit permits the use of XPI GETMAIN and FREEMAIN calls,
we recommend that you use the EXEC CICS GETMAIN and FREEMAIN
commands instead.
