I think the history of this runs as follows : (1) SMS SSI documentation is made available for $$$ to ISVs and not to normal customers (2) However - JES3 needs to get SMS volume info at some point - hence the minimum amount of doc and macros are distributed in SYS1.MODGEN (eg take a look at IGDVLD) (3) Some smart people look the the doc in IGDVLD and experiment and work out how the SMS SSI works (4) Tinkering and playing by various people in the 1980s/1990s including looking at IPCS dump formatting routines yield more info
I do not believe the author of SHOWMVS had access to the official doc - it was just reverse engineered from IGDVLD.

Presumably whoever coded the subsys call to SMS within SHOWMVS had access to some kind of doc (or to previously written working code, the author of which had access to the doc... etc.), and I would like to know more about the doc myself. Perhaps there are other subsys calls to SMS which return useful information. I would much rather look at original doc than at working code that exploits one particular function and reveals nothing about other functions. If this doc is restricted, then how could SHOWMVS be made public?

John, Checkout SHOWMVS. It makes a subsys call to SMS to do just that.

I am updating an old DASD management program. It does a UCBSCAN to scan the online DASD volumes and an LSPACE to get the space information from them. I also get the Format 4 DSCB. I check DS4SMSFG to see if the volume is SMS managed or not. I would like to output the storage group name if it is. But I cannot find any indication of how to get that information. I know it is possible because QuickRef does it. Is this another of the "if you want to know that, you need to give us a lot of money and sign an NDA" part of z/OS? I really dispise that of IBM. No wonder I like GNU software. Oh, well, "anything for a buck!" is the main corporate motto in today's world.
