The sample program for the XALTENF and XICTENF exits, DFHXTENF
One program can be used for both exits, or a separate program can be written for
each. Figure 2 shows the executable code from the supplied sample program
DFHXTENF, which can be used for both exits. DFHXTENF rejects transient data
requests, because the action in this case is very much installation-dependent.
Important
The example is intended purely as a demonstration of some of the possibilities
available, and would be impractical in a production environment.
