Apologies, you certainly did not say anything about production.

I don't like the idea of someone else turning on all the checking options 
"automatically" when my program needs some development or maintenance.  I 
prefer to be the one to decide which (if any) of those options I may need to 
debug a problem or verify new code.  Besides, all a programmer has to do to 
thwart any automatic option setting is to use a PROCESS card to turn off the 
options they don't want to use.

From the application programmer's point of view, your RFE if automatically 
imposed would force me to keep changing code until all messages were handled 
because my program always abends when it completes if I don't handle those 
messages.

From a managers point of view, why are you forcing my programmer to make 
unplanned code changes that may introduce as many bugs as it purportedly 
resolves?  I don't necessarily always subscribe to this philosophy, but it is 
very common and managers do have some legitimate concerns about unplanned code 
changes.

Unit testing is a bit more challenging when your program always abends while 
you are trying to test a logic change not associated with the code that 
generates checking messages.  Annoying too if you are running an interactive 
debugging session and the program abends at the end of processing.

I might see turning the existing checking options on automatically with the ABD 
sub-option in the full-volume regression testing stage to see if any bugs were 
missed during unit testing because those logic paths were not exercised, but 
not otherwise and probably not at all if I know there are unhandled checking 
messages being generated for this particular maintenance cycle.

I still agree with Jeffrey's response that since the compiler options already 
allow for the ABD sub-option you will probably get "already delivered" as an 
answer to your RFE.  Not a big help if you have "legitimate" code that triggers 
the option check which you don't want to change right away, but I would first 
question whether any such code is actually legitimate and not a problem.  If 
it's actually broken it ought to be fixed ASAP, though one's manager may or may 
not agree with that opinion (see above).

If the point is to generate all the possible sub-option MSG messages from a 
batch run or CICS transaction and then "tell the programmer" via abend to be 
sure to go look at the message output, I do not see any real usefulness in such 
an option.  If the programmer doesn't know enough to go look at the messages 
when they asked for them (or were told they must ask for them and check the 
results), then there isn't much you can do beyond telling them to RTFM and talk 
to their manager about it.

OTOH I think the idea of being able to "turn off" selected options around 
sections of code could be a useful idea.  Kind of like C/C++ "pragma(packed) 
and "pragma(reset)" around structure definitions but for executable code.  That 
has possibilities, but again you (and your manager) should probably first 
question whether such code sections are really "ignorable" for any given check.

I never said anything about production.  This would be (in our environment, 
anyway) set automatically for any development compiles only.

I agree with Jeffrey's comment and will add one of my own:  No program should 
be installed into QA or UAT or production libraries with SSRANGE or ZONECHECK 
or any other debugging option turned on at all.  There should be lifecycle 
software rules in place to automatically prevent it from ever happening.

Debugging options are for debugging problems and for unit and regression 
testing, never for production.  You are costing yourself serious CPU usage to 
leave them turned on in production.  When a programmer is debugging or changing 
code they should already know enough to look at the message output (batch or 
CICS) when they have debugging compiler options turned on.  If they don't know 
that then they don't deserve the label "programmer".

Like the old vaudeville routine said, "Patient: Doctor!  Doctor!  It hurts when 
I do that!"  "Doctor: Well, don't do that!"

Unless you have other specific examples, both NUMCHECK and SSRANGE already 
offer the ABD sub-option. I would think the RFE would be rejected as already 
delivered.
