AFAIK, the only tool to do that is FileAid. See the relevant documentation.

Alternatively, you can use IEBGENER/IEBCOPY to copy your dataset to new dataset with larger size.

I found this ISPF/PDF edit macro which adds specified amount of cylinders to the dataset. Let me know whether it works or not.

hi,
IEBCOPY & IEBGENER IS TO COPY TO OTHER FILES. mY ISSUE IS WHETHER I CAN INCREASE THE SIZE OF SAME DATASET.

I think it is not possible to increase the dataset size once it is created.....
the only possibility is to copy the dataset to another dataset using the above utilities(IEBCOPY,IEBGENER).

If U got any other way, plz let me know.... Meanwhile i will let u know using File-AId.

Yes. It is possible to increase the space of an existing dataset without copying it to another dataset. Not necessary to duplicate it if you have "PDS Command, Version 8.2" installed in your shop.

Do you have this? If you have then you can "PDS is a TSO command for Partitioned Data Sets. You can control PDS with subcommands which manipulate the entire partitioned data set or process individual partitioned data set members."
