Correct. I usually think of it FBS as meaning only that there are no short blocks, but there are other requirements, including: * Every track except the last contains the same number of blocks. * Every track except the last is filled as determined by the track capacity formula established for the device. >As far as I know, it is simply that guarantee that is the difference, >so it can be acted upon. S meaning "this data set has not been >MODded Are you sure? I'm not sure, but I thought that MOD would start by filling up the last track. BTW, IPCS requires FBS for dump data sets. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
