Hi Jack, have a look at ICKDSF parameter "EXTVTOC(n): Expands the VTOC at its current location." This may do what you want. Regards Michael

Back on those days, if memory serves me right, the only way to extend a VTOC was to clean the DASD of all its contents, put it offline, and recreate the VTOC with the new size. As a few years have passed, I have been going through the ICKDSF manual trying to find out if a VTOC can be extended without having to clear the volume first. I can not say that I have became enlightened. It seems to be possible but I am not quite sure about it. And this being a production volume I really would hate if things do not work as expected. So, in a nut shell, can I extend a VTOC from 90 to 900 tracks without having first to clean the DASD of all its files? Thank you in advance for any help, Best regards Jack ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
