UEPICNTI
Address of 8 bytes containing, for function-shipped START
commands, the netname of the last system from which the request
came.
For START commands issued in this system by transaction routing
to a task, the netname of the last system from which the task was
routed.
For other START command situations, the field pointed to contains
blanks.
UEPICSYI
Address of 4 bytes containing, if UEPICNTI contains a netname,
the corresponding SYSID.
If UEPICNTI does not contain a netname, the field pointed to is
blank.
UEPICNTO
Address of 8 bytes containing the contents of UEPICNTI.
If it sets a return code of ‘UERCNETN’, your exit program must
place in this field the netname of the system to which the ATI
request should be sent.
UEPICSYO
Address of 4 bytes containing the contents of UEPICSYI.
If it sets a return code of ‘UERCSYSI’, your exit program must
place in this field the sysid of the system to which the ATI
request should be sent.
UEPICNNI
Address of a 4-byte input field containing the netname of the
terminal on which the transaction is to run, if this is known to CICS.
If CICS does not know the netname, the addressed field contains
blanks.
UEPICNNO
Address of a 4-byte input/output field containing, on invocation, the
contents of UEPICNNI. Your exit program can use this field to
supply the netname of the terminal on which the transaction is to
run. It is important that your exit program supply a terminal
netname if the TOR to which it directs the ATI request is a member
of a VTAM generic resource.
