Exit XFCAREQ
When invoked
Before CICS processes a file control SPI request.
Exit-specific parameters
UEPCLPS
Address of a copy of the SPI command parameter list. See “The
command-level parameter structure” on page 86.
UEPFATOK
Address of a 4-byte area that can be used to pass information
between XFCAREQ and XFCAREQC on a single file control SPI
request.
UEPRCODE
Address of a 6-byte hexadecimal copy of the EIB return code
EIBRCODE. For details of EIB return codes, see 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 which can be used to pass information
between successive file control SPI requests within the same task
(for example, between successive invocations of the XFCAREQC
exit).
UEPRECUR
Address of a halfword recursion counter. The counter is set to zero
when the exit is first invoked and is incremented for each recursive
call.
Return codes
UERCBYP
Bypass this request.
UERCNORM
Continue processing.
UERCPURG
Task purged during XPI call.
XPI commands
All can be used.
API and SPI commands
All can be used.
Note: Take care when using recursive commands. For example, you must avoid
entering a loop when issuing a file control SPI request from the XFCAREQ
exit. Use of the recursion counter UEPRECUR is recommended.
