I agree, in principle. Default handlers, like CPF0000, can cause more trouble than problem(s) solved. What really amazes me, even more than Rob's example, are people who put CPF0000 at the top of the CL so that it acts on everything.
I do use the system reply list during conversions to respond to messages that I *know* will occur. For example, if I am dropping a field from a table, I don't want to have to reply 'I' to every CPA32B2 (File change may result in data loss) during the conversion. Other than that situation, I don't have an instance of using CHGJOB INQMSGRPY(*SYSRPYL). However, I can think of places where one might legitimately use it (unattended backups come to mind) when part of a thought out plan.

Chuck,
I've never been a big fan of default handlers. I'd rather the program
halt on the line in error. If the problem is such an obscure error then
often corrective action can be taken elsewhere and an R to retry fits the
bill nicely. Now, a detailed MONMSG on a particular error is completely
acceptable. My detailed I do not mean
DLTF (MYLIB/MYFILE)
MONMSG CPF0000
I mean
DLTF (MYLIB/MYFILE)
MONMSG CPF2105 /* File not found */

Re: system reply list entries
On many systems a user with *JOBCTL would need only perform WRKOUTQ
QEZDEBUG to review what problems had transpired since a prior review had
marked which were already reviewed. This is because the D=Dump
incidents would have produced QPDSPJOB, QPSRVDMP, QPPGMDMP, and possibly
other spools which were directed [per cleanup] into the QEZDEBUG output
queue.
That nobody is informed, is again about properly coded programs. If
the business decides someone needs to be informed because an operator is
not monitoring the system, then the developers need to code a generic
monitor for unexpected errors in the application, for which the handler
effects desired notifications. So instead of allowing the program to
fall into its run-time inquiry handling, either asking the user or the
reply list how to respond, the application makes the decision. Thus
what is in the *SYSRPYL is moot, as the real issue is a programming
problem; a failure to meet the business rule for which someone needs to
be informed of the failing code.
If the entries are removed to prevent the D=Dump action, then the
message handling defers to *RQD processing which means the user\operator
gets the option to reply. As a customization change to the system, the
removal of those reply list entries [RMVRPYLE] should be included in the
system change management script, to be re-run after each upgrade [in
case the OS install blindly resets those defaults].
Note: ADDRPYLE allows the special value *ALL for a message range. I
am not sure why, as it is a bad idea. Primarily because not all
messages will have the same possible allowed replies. Additionally
there is little to no assurance that a program will respond [well; more
likely, unpredictably] to either an invalid reply or an escape from the
message handling component indicating that the reply was invalid.
Regards, Chuck

Issue at this shop is that with the autoreply list set to D)ump all RPG

fails unless the user says something. No one actually reviews qsysopr
message queue so all looks fine and dandy.
Hey, if a tree falls in the forest and no one is around to hear it does
it make a sound?
What do others have in their sysrepl?
