>Of course I know the offset and old data. What I cannot predict is disk address and in fact cannot understand why AMASPZAP wants me to provide unnecessary information.
I think you may misunderstand the parameters. The offset on the VER and REP statements is the byte offset from the beginning of the physical record, aka block, you told SPZAP to look at. How would SPZAP know which block to work on, if you don't tell it? The CCHHR is exactly this information. -- Peter Hunkeler -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
