If the initial allocation was performed in multiple extents, is there any way to retrieve the initial request? HSM MIGRATE/RECALL can coalesce extents, further obscuring the initial request. I have used ISPF to capture the attributes of a data set; changed only the DSN, then allocated. The new data set was smaller because ISPF? Allocation? applied a correction for 3380/5590 capacity ratio. (I understand this is optional, but our site had it turned on.) I'd like to be able to code "BLKSIZE=0,SPACE=(1,10000000000),..." and let allocation and SDB figure it out. They're only trying to help me. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
