The terminal-not-known sample exit program
You can use this sample global user exit program to handle terminal-not-known
conditions arising from START and ATI requests:
DFHXTENF
A sample global user exit program, designed to be invoked at the XALTENF
or XICTENF exit. The sample source code is shown on page “The sample
program for the XALTENF and XICTENF exits, DFHXTENF” on page 214.
The transaction-abend sample exit program
There is one sample global user exit program for the XPCTA exit point:
DFH$PCTA
This sample global user exit program is designed to be invoked at the
XPCTA exit, to test whether the abend was caused by a storage protection
exception condition. It is described on page “The sample XPCTA global
user exit program, DFH$PCTA” on page 169.
Example program
As well as the sample programs supplied in source code, there is an example
listing, DFH$XTSE, that shows you how to:
v Use EXEC CICS commands in a global user exit program
v Use EXEC CICS commands and XPI calls in the same exit program
v Modify the command parameter list in EXEC interface exits such as XTSEREQ
and XICEREQ.
DFH$XTSE is listed on page 807.
