I wonder why space is being released with the TSO ALLOC command in the first place, this ALLOC command does not do this by itself. It must be defined somewhere in the mgmtclas definitions and/or ACS routines.

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 information, services and offers, please visit our web site: http://www.klm.com.
