How to free unused space of the dataset? Suppose we have created a dataset with the property of SPACE=1 CYL and the used space is 5 TRKs so i want to release the unused SPACE allocated to the dataset.
I tried to use IEBCOPY but couldnt succeed.
Can any body help me on this? |

Deepak,
Why dont you use RLSE (during creation) parameter for releasing unused but allocated space? |

from ispf option 3.4 put an F in front of the dataset and it will free the unused space... |

If you allocate in CYL then RLSE parm in the JCL will release all unused cylinders and not the unused tracks within the last used cylinder.
The same is true for using F in 3.4 |
