When a new data set is created without specifying BLKSIZE, and written to by the binder, the data set ends up with BLKSIZE=32760. I just ran a test on z/OS 2.3, and there was no DATACLAS involved. I don't know whether it was set by DFSMA or by the Binder. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
