EIBRSRCE.
Return codes
UERCNORM

UERCBYP
The file control EXEC interface program should ignore this request.
UERCPURG
Task purged during XPI call.
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.
API and SPI calls
All can be used.
Notes:
1. Take care when issuing recursive commands not to cause a loop. For example,
it is your responsibility to avoid entering a loop when a file control request is
issued from the XFCREQ exit. Use of the recursion counter UEPRECUR is
recommended.
2. Exit programs that issue EXEC CICS commands must first address the EIB.
See “Using CICS services” on page 5.
3. Exit programs that issue EXEC CICS commands, and that use the DFHEIENT
macro, should use the DFHEIRET macro to set a return code and return to
CICS. See “Returning values to CICS” on page 10.
Exit XFCREQC
When invoked
After a file control API request has completed, and before return from the
file control EXEC interface program.
