The EIB

Copies of EIBRSRCE, EIBRCODE, EIBRESP, and EIBRESP2 are passed to the exit, so that you can:

Modify or set completion and resource information in XTDEREQ and XTDEREQC
Examine completion and resource information in XTDEREQC.

You can update the copies of EIBRSRCE, EIBRCODE, EIBRESP, and EIBRESP2 that you are given in the parameter list. Transient data copies your values into the real EIB after the completion of XTDEREQC; or if you specify a return code of ‘ bypass’ in XTDEREQ.

You must set valid transient data responses. You must set all three of EIBRCODE, EIBRESP, and EIBRESP2 to a consistent set of values, such as would be set by CICS® transient data to describe a valid completion. CICS does not police the consistency of EIBRCODE, EIBRESP, and EIBRESP2. However, if EIBRCODE is set to a non-zero value and EIBRESP is set to zero then CICS will override EIBRESP with a non-zero value. To aid you in setting the values of EIBRCODE, EIBRESP, and EIBRESP2, the values used by transient data are specified in DFHTDUED.
