UEPCLPS
Address of a copy of the command parameter list. See “The
command-level parameter structure” on page 63.
UEPNQTOK
Address of a 4-byte area which can be used to pass information
between XNQEREQ and XNQEREQC for a single enqueue
request.
UEPRCODE
Address of a 6-byte hexadecimal copy of the EIB return code
EIBRCODE. For details of EIB return codes, see 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 which can be used to pass information
between successive enqueue requests within the same task (for
example, between successive invocations of the XNQEREQC exit).
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.
UEPSCOPE
Address of the 4-byte ENQSCOPE name used.
Return codes
UERCNORM
Continue processing.
UERCPURG
Task purged during XPI call.
XPI calls
All can be used.
API and SPI commands
All can be used, except for:
EXEC CICS SHUTDOWN
EXEC CICS XCTL
You can update the copies of EIBRCODE, EIBRESP, and EIBRESP2 that you are
given in the parameter list. If you update the values, CICS copies the new values
into the application program’s EIB after the completion of XNQEREQC or if you
specify a return code of UERCBYP in XNQEREQ.
You must set valid enqueue responses. You must set all three of EIBRCODE,
EIBRESP, and EIBRESP2 to a consistent set of values, such as would be set by
the enqueue domain to describe a valid completion. CICS does not check the
consistency of EIBRCODE, EIBRESP, and EIBRESP2. If EIBRCODE is set to a
non-zero value and EIBRESP is set to zero, CICS will override EIBRESP with a
