Exit XTDEREQC

Exit XTDEREQC is invoked after a transient data API request has completed, and before return from the transient data EXEC interface program.

Exit-specific parameters
UEPCLPS
Address of the command-level parameter structure. See The UEPCLPS exit-specific parameter.
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.
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 Using the task token UEPTSTOK.
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.
UEP_TD_REMOTE_SYSTEM
If the request is to be sent to a remote region, is the address of an area containing the 4-byte name of the remote region. (The remote region may have been specified by, for example, the SYSID option of the command, function shipping, or the REMOTESYSTEM option of the TDQUEUE definition.)

If the request is to be executed on the local region, this parameter is the address of a 4-byte area containing blanks.

UEP_TD_REMOTE_NAME
If the request is to be sent to a remote region, is the address of an area containing the 4-character name by which the queue is known in the remote region.
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 commands
All can be used, except for:
  • EXEC CICS® SHUTDOWN
  • EXEC CICS XCTL
Note: Take care when issuing recursive commands. For example, you must avoid entering a loop when issuing a transient data request from the XTDEREQC exit. Use of the recursion counter UEPRECUR is recommended.
