Thank you all for your input. Unfortunately I do not have FDR on this system. That would be a very good option (my problem is with files that have enqueues from active STCs, such as a few CICS address spaces. And the next programmed IPL is still a long way away... And this is a model 27 that on which was placed a VTOC that would be small on a model 3. So, there is free space on the DASD but not on the VTOC. Best regards, Jack
