IBM SC33-1683-02 - Manual (Page 167)

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 “Using the task token UEPTSTOK” on page 145.
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 interval control EXEC interface program should ignore this
request.
UERCPURG
Task purged during XPI call.
XPI calls
All can be used. You can also use EXEC CICS API commands at this user
exit.
Although the exit permits the use of XPI GETMAIN and FREEMAIN calls,
you are recommended to use the EXEC CICS GETMAIN and FREEMAIN
commands instead.
API and SPI commands
All can be used.
Note: Take care when issuing recursive commands not to cause a loop. For
example, it is your responsibility to avoid entering a loop when an interval
control request is issued from the XICEREQ exit. Use of the recursion
counter UEPRECUR is recommended.
Exit XICEREQC
When invoked
After an interval control API request has completed, and before return from
the interval control EXEC interface program.
Exit-specific parameters
UEPCLPS
Address of the command-level parameter structure. See “The
UEPCLPS exit-specific parameter” on page 138.
UEPICTOK
Address of a 4-byte token passed from XICEREQ. This allows
XICEREQ to, for example, pass a work area to XICEREQC.
UEPRCODE
Address of a 6-byte hexadecimal copy of the EIB return code
