between successive enqueue requests within the same task (for
example, between successive invocations of the XNQEREQ 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 to be used.
Return codes
UERCBYP
Bypass this request.
UERCNORM
Continue processing.
UERCPURG
Task purged during XPI call.
XPI calls
All can be used.
API and SPI commands
All can be used.
Note: Take care when issuing recursive commands. For example, you must avoid
entering a loop when issuing an enqueue request from the XNQEREQ exit.
Use of the recursion counter UEPRECUR is recommended.

After an enqueue API request has completed, before return from the

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 the
CICS
Application Programming Reference manual.
UEPRESP
