It's not VM that's doing it: it's MVS (i.e. the VM guest).

CS is an unprivileged instruction, so when MVS executes it, it causes a program check (which Hercules then logs).
? Not clear to me why it matters if an instruction program checks because of a protection exception (4) or because it's a privileged instruction (2). Either way it's Hercules that sees it and may report on it.

If so I missed understanding that. Yes, I got that CS is
being used to test writability to a location. But WHY is
VM doing THAT? This is the part I missed. It's not VM that's doing it: it's MVS (i.e. the VM guest). CS is an unprivileged instruction, so when MVS executes it, it causes a program check (which Hercules then logs). Does it make sense to add protection exceptions to the VM
OSTAILOR setting rather than setting it manually? No. Because Protection Exceptions should NOT normally be occurring. It's not an exception that is considered "routine" (expected) in a normal operating environment (which are the only type of exceptions that OSTAILOR is designed to filter). One would expect that if this is a "normal" situation with VM/370 MVS. (Not VM) that the VM setting MVS setting. :) would turn this report off. Correct! Which is precisely WHY it's *not* turned off! Because it's NOT considered "normal/expected"! It's *unusual*. It's not something that regularly (routinely) happens in a normally functioning operating system. (Obviously it is reported when OSTAILOR is not being
used.) Or even when OSTAILOR *is* used, which was what I tried to make clear. That's why if MVS 3.8j is being run either natively -OR- under VM, you (currently!) need to add a "PGMTRACE -04" statement to your Hercules configuration file if you want to suppress their being reported by Hercules. What mystifies me is why after years of people using VM/370
and MVS as guest that this is the first time this apparently
legitimate situation has arisen. Actually it's not the first time. As Dave pointed out in his reply it was actually mentioned over 19 years ago too: (I get it that obviously without OSTAILOR the report would happen.)
But why protection exceptions IN THIS CASE must be manually
turned off is what confuses me. Because Hercules does not consider such exceptions to be "routine" (ordinary/expected) in a *normally* (properly!) functioning operating system! Hercules considers such exceptions to be "unusual" and "out of the ordinary" and usually indicative of a programming error. Thus, by default, it does NOT filter them out and reports them instead. (This sort of gets back to why VM/370 MVS! is testing location writability.) That would still suggest
that there is something unique going on here that others have
not encountered. Or maybe they were all smart enough to know
to manually turn off reporting of protection exceptions. I think the thing that is unique that is going on here is the distributers/maintainers of the MVS 3.8j and VM systems ship their product with OSTAILOR QUIET purposely enabled in order to prevent this very issue. It only popped up this time because Jim Snellen reported seeing the messages in his log file because he obviously WASN'T using the stock Hercules configuration file that comes shipped with the normal MVS/VM distributions, and was instead using a Hercules configuration file that he constructed himself (probably via my HercGUI, which specifically mentions using NULL or QUIET is *not* recommended). -- "Fish" (David B.

Re: virtual memory and overlays
Just a wild question here with regard to the compiler we need to use for cREXX.
The gcc compiler ported to VM/370 suffers address space size problems (so I have heard from reliable sources) and even has led to the ¡®380¡¯ version of Hercules to be able to be compiled (so I have read). A larger language like PL/I does not have these problems however, and when I read up about its history, this seems to be due to the fact that it has a lot of ¡®phases¡¯ that could be implemented in overlays, something the linkage editor/loader could handle in the pre-virtual memory days (and following IBM¡¯s reputation for preserving compatibility, probably still can).
Yeeesss...
This has led to the anecdote that one IBM lab was toiling at phases and overlays to fit PL/I in even the smallest of S/360 machines, while the other team was putting the finishing touches on virtual memory. Should they have talked to each other, a lot of work could have been avoided.
It's conceivable, but probably a lot more subtle in the details. IBM has roughly forever pitted internal groups against each other, and there is generally a winner and one or more losers. Sometimes the losers manage to get their project repurposed into something else, and then become winners. Or if not, the people get reallocated and the cycle begins again. I doubt that's going to change.
Now gcc is a lot bigger than anything from that era, and we have problems - where it first compiled cRexx on VM/370, now it does not. My speculation is that if we went in the opposite route than the historic development went, and we packaged this compiler in overlays, we could lessen its memory footprint.
Is there anyone from that era who still knows how this is done, can tell us whether it would be possible, and can advise on what to do?
Overlays (officially "planned overlay structure") are one way of several to save space. Another is to do it yourself on the fly with LOAD/LINK/XCTL, and I believe, though I'm not 100% sure, this is what PL/I F does. (There is a summary of how this works in the PLM for these compilers.) In both cases the saving from overlay schemes is in code space, and I rather doubt that this is the main problem. Programs like GCC, and pretty much everything else these days, use a huge amount of *data* storage to keep track of the program being compiled as it progresses through the various stages.
PL/I F, like Assembler F, and probably all the other old style compilers, uses work files, which are disk datasets. Data structures representing the various apects of the program at various stages - for example the symbol dictionary - are written to and read back from these disk work files. Whether there is a single work file that's logically partitioned or, as with Assembler F, three different physical files, each containing different sets of work in progress items, main storage is typically used for not much more than buffers for the data items in the work files.
One can think of this as a kind of application-specific virtual storage, rather than the general purpose virtual storage we are all used to.
Something like GCC does indeed have a much larger executable, but it also has a very much larger use of data storage, and I think has no concept of work files at all.
Before setting out on anything like your approach I would want to understand where the main storage is going.

Re: How to clear EREP using CPEREP and sometimes I wish for printed manual again

virtual memory and overlays
Just a wild question here with regard to the compiler we need to use for cREXX.
The gcc compiler ported to VM/370 suffers address space size problems (so I have heard from reliable sources) and even has led to the ¡®380¡¯ version of Hercules to be able to be compiled (so I have read). A larger language like PL/I does not have these problems however, and when I read up about its history, this seems to be due to the fact that it has a lot of ¡®phases¡¯ that could be implemented in overlays, something the linkage editor/loader could handle in the pre-virtual memory days (and following IBM¡¯s reputation for preserving compatibility, probably still can).
This has led to the anecdote that one IBM lab was toiling at phases and overlays to fit PL/I in even the smallest of S/360 machines, while the other team was putting the finishing touches on virtual memory. Should they have talked to each other, a lot of work could have been avoided.
Now gcc is a lot bigger than anything from that era, and we have problems - where it first compiled cRexx on VM/370, now it does not. My speculation is that if we went in the opposite route than the historic development went, and we packaged this compiler in overlays, we could lessen its memory footprint.
Is there anyone from that era who still knows how this is done, can tell us whether it would be possible, and can advise on what to do?
best regards,

Re: Adding disks found in DMKRIO and CPEREP error
Hello Bob,
Thank you for letting me know about the 3390 drives.? I'll remove them from my vm370ce.conf file.? I'll look through DMKRIO for other drives, I can add to the Hercules configuration.

Re: Do I have a looping issue?
Hercules should not be in the business?of reporting program checks. It should only report on a disabled wait condition, which it does. OSTAILOR is a useless option and should default?to QUIET. If an application program checks, the underlying OS produces the appropriate messages. If an OS program checks, it either produces?a dump, or loads a disablbed wait with memory intact for problem determination or a standalone?dump. Just my 2 cents. Best regards,

Adding disks found in DMKRIO and CPEREP error
Hi,
I'm trying to add disks found in DMKRIO?because I want to create my own accounts and on different drives.
I'm running into three issues.
1) My error recording area is full.? When I run CPEREP, I get the following error.? Again it has been so long since I was a systems programmer I forget how to run and also fix stuff.

2) How do I copy and paste text from a 3270 screen to email without having it look so crappy.? Any thoughts?? Yeah, copy line by line, but ...
3) Why my drives aren't showing up?? OK, I see.? Hercules doesn't create the drives just because you add them to the configuration file.
** I'm not sure of the command and the parameters for creating the drives.? Yes, I did read the Hercules 4 webpage manual for creating drives.? I didn't understand it well enough to feel safe using the command.? Thus, I'm asking for help here.
** I noticed in the webpages the 3390 has various model numbers and NONE of them look to NOT have a model number?? In DMKRIO?the 0AE0-0AFF entries are for a 3390, but doesn't have a model number.? What model number should one use for these drives, when creating them in Hercules?
I'm starting to see the advantage of using the Hercules GUI (especially for a newbie to Hercules).
I'm adding to the message the entries I added to the vm370ce.conf file.? I'm hoping I did them correctly; did I?
# 32 3350 drives added by me for my use.? They are already defined in DMKRIO.
08A0 ? ?3350 ? ?disks/vm08A0_BGM001.cckd ro sf=disks/shadows/vm08A0_BGM001_*.shadow

*/
num = 1
base_haddr = '0AE0'? /* Change for the address you're using */
haddr = base_haddr

Is AP or MP support in VM/CE?
Hi,
Just wondering is AP/MP support in VM/CE?? I remember having (at Owens Corning Fiberglas) two systems; one was an AP and the other MP.
Thanks,

turned off is what confuses me. (This sort of gets back to why VM/370
is testing location writability.) That would still suggest that there
is something unique going on here that others have not encountered.
Or maybe they were all smart enough to know to manually turn off reporting of protection exceptions.
It appears that tk4- issues an OSTAILOR QUIET so that will hide it for many users Dave

Have we actually determined WHY these protection exceptions are occurring,
albeit apparently legitimately with VM/370? If so I missed understanding that.
Yes, I got that CS is being used to test writability to a location. But WHY is VM
doing THAT? This is the part I missed.
Does it make sense to add protection exceptions to the VM OSTAILOR setting
rather then setting it manually? One would expect that if this is a "normal"
situation with VM/370 that the VM setting would turn this report off. (Obviously
it is reported when OSTAILOR is not being
used.)
What mystifies me is why after years of people using VM/370 and MVS as guest
that this is the first time this apparently legitimate situation has arisen. (I get it
that obviously without OSTAILOR the report would
happen.) But why protection exceptions IN THIS CASE must be manually turned

Harold, its not the first time it has occurred, it was first mentioned 19 years ago on the YAHOO on the Hercules-390 group. you need to skip the first message then if you read down the entire thread all your questions are answered

itself uses (dispatches, since its ultimately in control of (what it
thinks is) the real hardware) -- is never what the VM guest (i.e.
MVS in this case) thinks is (or sees as) ITS "real" PSW. What MVS
always "sees" is what it THINKS is a "real" PSW, but it's actually a
virtualized PSW that VM fakes (emulates) for it.
The PSWs that VM *itself* uses however (and thus what Hercules reports
on the HMC), are the actual real hardware PSW that VM used to dispatch
its VM guest with.
So in the context of our original discussion, the PSWs that Hercules
was reporting were the REAL hardware PSWs that VM itself dispatched
its MVS guest with.
Which, as explained, were causing REAL (bona-fide) Protection
Exception program interrupts.
MVS might not have been "seeing" any Protection Exception program
interrupts, I don't know (I'm guessing it probably wasn't; I'm
guessing that VM was intercepting them and dealing with them itself),
but the Protection Exception program interrupts WERE actually
occurring on the real hardware.
On real hardware (i.e. on real IBM machines), these Protection
Exceptions were actually occurring, but were not being "reported"
(displayed) anywhere that the machine operator/user could see. But
they were certainly happening!
On Hercules however, as a courtesy (i.e. in order to be helpful),
whenever certain "unexpected" program interrupts occur, it DOES report
them. It DOES display them.
And Hercules was reporting all of these many Protection Exception
program interrupts that were occurring because its OSTAILOR setting
(or more technically, its "pgmtrace" setting(*)) was telling Hercules
that they SHOULD be reported (displayed).
You won't "see" them on real IBM hardware (because IBM hardware
doesn't bother to "report" them), but you *WILL* see them on Hercules!
As long as your OSTAILOR (i.e. pgmtrace(*)) says to do so of course.
I hope that all makes sense now.
---------------------
(*) The "OSTAILOR" configuration file statement is just a more
convenient (more compact) way of specifying a long series of
"PGMTRACE" commands that define WHICH program interrupts should be
reported and which ones SHOULDN'T be reported. Code 11 program
interrupts for example (Page Faults) occur all the time and are thus
largely uninteresting to the Hercules user, so they're typically
marked to not be reported. (All of our predefined OSTAILOR setting
specify a pgmtrace value with code 11 marked as "don't report".)
OTHER program interrupts however (such as Protection Exceptions,
Addressing Exceptions, Specification Exceptions, OPERATION
EXCEPTIONS(!), etc) are marked as "DON'T filter!" (i.e. "Please
report!"), since they almost always indicative of a serious
programming error.
And USUALLY (not always, but *usually*) the Hercules user who is
running Hercules wants to know whether their software is operating
correctly or messing up. So Hercules helpfully reports such
occurrences -- according to what it was told to report (which is
controlled via its PGMTRACE setting of which the OSTAILOR statement is
simply a more convenient way of specifying).
Hope that helps!
