UEPRCODE
Address of a 6-byte hexadecimal copy of the EIB return code
‘EIBRCODE’. For details of EIB return codes, refer to the
CICS
Application Programming Reference manual.
UEPRESP
Address of a 4-byte binary copy of the EIB response code
‘EIBRESP’.
UEPRESP2
Address of a 4-byte binary copy of the EIB response code
‘EIBRESP2’.
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 228.
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.
UERCBYP
The transient data 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 commands
All can be used.
Note: Take care when issuing recursive commands. For example, you must avoid
entering a loop when issuing a transient data request from the XTDEREQ
exit. Use of the recursion counter UEPRECUR is recommended.
