The EIB
Copies of EIBRSRCE, EIBRCODE, EIBRESP, and EIBRESP2 are passed to the
exit, so that you can:
v Modify or set completion and resource information in XTDEREQ and
XTDEREQC
v 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.
