DFHXTENF is a sample global user exit program that handles
terminal-not-known conditions that arise from START and ATI requests.
It is designed to be invoked at the XALTENF or XICTENF exit.
About DFHXTENF
DFHXTENF is a sample program
that can be used for the XALTENF and XICTENF exits. Based on DFHXTENF,
you can create your own global user exit program that can be used
for both exits, or create a separate program for each exit.
Figure 1 shows the executable code from
the supplied sample program DFHXTENF. DFHXTENF rejects transient data
requests, because the action in this case is very much installation-dependent.
Important: The example in Figure 1 is intended purely as a demonstration
of some of the possibilities available, and would be impractical in
a production environment.
