‘EIBRCODE’. For details of EIB return codes, refer to EIB fields, in
the CICS Application Programming Reference manual.
UEPRESP
Address of a 4-byte binary copy of the EIB response code
‘EIBRESP’.
Note: If the file that has just been accessed is remote, the
addressed field contains zeros (even if UEPRCODE is
non-zero).
UEPRESP2
Address of a 4-byte binary copy of the EIB response code
‘EIBRESP2’.
Note: If the file that has just been accessed is remote, the
addressed field contains zeros (even if UEPRCODE is
non-zero).
UEPTSTOK
Address of a 4-byte token that is valid throughout the life of a task.
See “Use of the task token UEPTSTOK” on page 93.
UEPRECUR
Address of a halfword recursion counter. The counter is set to 0
when the exit is first invoked, and is incremented for each recursive
call.
UEPRSRCE
Address of an 8-character copy of the EIB resource value,
EIBRSRCE.
Return codes
UERCNORM
Continue processing.
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, except for:
EXEC CICS SHUTDOWN
EXEC CICS XCTL
Note:
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 XFCREQC 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 4.
