Default disposition is NEW,DELETE,DELETE. So, if you didn't specify DISP parameter, it should be deleted in both normal and abnormal cases.

If you create again, it shouldn't give any JCL error related to DISP parameter.

if u didn't get answer with this reply, ask in detail what exactly u want.

...continued with ksk's reply..consider this definition of DISP

DISP=(status, normal-termination-disp, abnormal-termination-disp)

Defaults of DISP are:

- If you omit the status subparameter, the default is NEW.

- If you omit the normal termination disposition subparameter, the default is DELETE for a NEW data set or KEEP for an existing data set.

- If you omit the abnormal termination disposition subparameter, the default is the disposition specified or implied by the second subparameter. However, if the second subparameter specified PASS, the default abnormal termination disposition is DELETE for a NEW data set or KEEP for an existing data set.

Hope this helps.

Hello,

If you have jcl that creates one or more files without a DISP= parameter, you should fix this jcl. Any time a file is to be created, the jcl should specify what should happen on a sucessful and an abended execution.

To do otherwise, it not a good proctice with the exception of datasets like sortwk.
