Exit XTDEREQ

When invoked

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
