Exit XTSEREQ
When invoked
Before CICS processes a temporary storage API request.
Exit-specific parameters
UEPCLPS
Address of a copy of the command parameter list. See “The
command-level parameter structure” on page 196.
UEPTQTOK
Address of a 4-byte area which can be used to pass information
between XTSEREQ and XTSEREQC for a single temporary storage
request.
UEPRCODE
Address of a 6-byte hexadecimal copy of the EIB return code
EIBRCODE. For details of EIB return codes, see the
CICS/ESA
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 temporary storage requests within the same
task (for example, between successive invocations of the
XTSEREQ 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.
UEPRSRCE
Address of an 8-character copy of the EIB resource value,
EIBRSRCE.
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 a temporary storage request from the
XTSEREQ exit. Use of the recursion counter UEPRECUR is recommended.
