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

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.

hey dude,this will work

//STEP1 EXEC PGM=IEFBR14
//DD1 DD DSN=datesetname *give the unwanted dataset name here*
// DISP=(MOD,DELETE,DELETE),

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
