To allocate a dataset in a non SMS environment you need access to a specific SMS STORCLAS.
Confused ? - You need an SMS STORCLAS to write a non SMS dataset

Not really correct. To create a NON-SMS managed dataset it needs to have attributes that cause the STORAGE CLASS ACS routine to not set a l storclass.
Some shops implement this by code in the ACS routine like this:
| Code: |
| IF &STORCLASS='NONSMS' THEN SET STORCLAS='' |
But there are many other ways that the ACS routines can also have a
| Code: |
| THEN SET STORCLAS='' |
For instance it may just be coded that if you specify a certain (NONSMS) volser in your jcl then the acs code will honour the allocation. eg
| Code: |
| IF &ANYVOL='SYS%%%' THEN SET STORCLAS='' |

Of course it is correct, in every occurence the STORCLAS is set to ''  |

Well expat, I just showed how it can be done without using any STORCLAS, so it isn't correct.
Any dataset that has NO STORCLAS set becomes non-SMS managed.
So it can be done without you needing access to any specific SMS STORCLAS. The ACS routines just have to be coded correctly.
By using:
| Code: |
| IF &ANYVOL='SYS%%%' THEN SET STORCLAS='' |
you can bypass the need... |

Yeah, but it's all site specific isn't it.
I never allow a non SMS allocation except to the chosen few, i.e. Storage, sysprogs, ( and dare I say it, even a couple of trusted JCLMs ).
I've always set it up that to be non SMS managed it must pass the filter for accepted users to STORCLAS=NONSMS, and of course filtered by DSN.
The way that you have shown - maybe there's more code to it - would allow ANYONE to allocate non SMS. Something I've found to be a real pain in past when people find out that they can - they almost certainly will - grab space anywhere. |

Hello,
And then they often complain when their data is either relocated or removed.
For my $.02, following the storage management standards should be a condition of continued employment. . . |

But that's the fun part of storage admin, tidying up the miscreants  |

I actually use:
| Code: |
WHEN (&USER=&TRUSTED_USERS AND &STORCLAS='NONSMS' AND ANYVOL=&NON_SMS_VOLS)
SET &STORCLAS='' |
My only point was that it doesn't have to be done that way. |
