Before CICS processes a transient data API request.
Exit-specific parameters
UEPCLPS
Address of the command-level parameter structure. See “The
UEPCLPS exit-specific parameter” on page 240.
UEPTDTOK
Address of the 4-byte token to be passed to XTDEREQC. This
allows you, for example, to pass a work area to exit XTDEREQC.
UEPRCODE
Address of a 6-byte hexadecimal copy of the EIB return code
‘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’.
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 243.
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, except for:
EXEC CICS SHUTDOWN
EXEC CICS XCTL
