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.

Subject: Getting the Storage Group name for a DASD volume.

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.
