Hi,
Well, what's the definition of "unwanted" here? |

Hi,
You can use IDCAMS to delete the datasets. Please identify "unwanted datasets" and then use an IDCAMS step with a disposition for those datasets as
| Code: |
| (MOD,DELETE,DELETE) |
Hope this helps. |

Why on earth would you want to code DD names using IDCAMS ??? |

I usually use IEFBR14, not IDCAMS.
The MOD is used to avoid a JCL error if the DSN does not exist going in. MOD allocates the DSN then deletes it at step term. |

IMHO, topic seems to be as if it's an "adhoc" request & not a regular JOB to be sechduled in production, so I thought (OLD,DELETE,DELETE) is better choice (best choice actually, DSN is "unwanted" already, so it must exist; if a DSN doesn't exist how can it be unwanted..) unless I misunderstood.
Personally, I also always used IEFBR14 to DELETE DSNs with DISP OLD. |

That's the joy of IDCAMS - One card per dataset, no need to code DISP to ensure non failure, and you even get the choice to set the RC is there are missing datasets from 8 to whatever
Far more flexible |

Back to the IEFBR14 technique. You can use any JCL step to insert the (mod,delete,delete) datasets, including IDCAMS.
Doesn't make sense in this case, but you can do it.
PS. Another advantage to expat's approach - you get a listing - handy if you misspell one or two. |
