No, TSO ALLOC only allocates the dataset. correct the parameters and you should be fine.

I allocate the same data set in ISPF 3.2 and the data set is allocated with 9 cylinders. The same SMS management class and data class is assigned for both allocations. Is it possible not to release unused space when using the TSO ALLOC command? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
