Hi Bob,

Well, on our systems I have made sure that all the dump options are set to
get me this information (I think). And given that our default options are
always asked for by each vendor, I don't think we'll be getting rid of them.
Also, IBM always asks for those options for their dumps. 
So unless IBM decides not to dump things anymore, that won't be a problem.

<vent on>
In order to avoid the infamous excuse 'the needed storage is not dumped',
all expensive options have to be there, anyway. And believe me, I am still
getting the excuse and problems not properly debugged. When I verify that
storage is indeed not there, *I* am the one that has to ask 'Why is it not
there'. IBM doesn't even care other than telling me they cannot do anything.
So if the dumping process gets changed by IBM, I'll still attempt to get
those data.</vent off>

When I started out, I used that option. In 90% of all cases the storage key
was needed for the summary data, and that key wasn't included back then, so
I had to use rsmdata anyway.

Don't know what I'll be needing. Last time I checked why storage is not
dumped, I looked at all the output from rsmdata realframe (and then still
had to ask Jim what it means).

No, I skipped that. I went from OS/VS1 to hbb4420. It confused the hell out
of me that there was something called JES and that no one needed to start
the card readers anymore. :-)

Best regards, Barbara
