IBM SC34-6814-04 Exit XALTENF

UERCNETN
Netname of TOR returned
UERCSYSI
Sysid of TOR returned.
For return codes UERCNETN and UERCSYSI, the exit program must place the
netname or sysid of the terminal-owning region in fields UEPxxNTO or UEPxxSYO
(where xx is ALor IC).
If the terminal-owning region is a member of a VTAM generic resource, the exit
program should place the netname of the terminal in field UEPxxNNO. For
information about using ATIwith VTAM generic resources, see Using ATI with
generic resources, in the CICS Intercommunication Guide.
Exit XALTENF
When invoked
By the terminal allocation program when the terminal that an ATIrequest
from transient data or interval control requires is unknown in this system.
The exit program is expected to give a return code indicating whether the
terminal exists on another connected CICS system and, if so, on which one.
