I must agree I was very vague on reporting my problem. Anyway, I shall begin thanking you all.
I am running a recovery on lost ESDS VSAM file due to VSAM UCAT disaster on a VM/ESA+VSE/ESA (both 2.3 backlevel versions) installation. I have inspected the file volume ( I had a full listcat showing only one extension, in the beginning of the 3390 pack). So I have done a DDR PRINT and the user identified his file records. That was great, so now I have to extract the vsam CI's from the middle of a VSAM SPACE and put them in a sequential file for the user to pick his records back. Well, how should I pick those 4k records in the midle of a 3390 extent ? I have never used PIPE but I Will read about it, you may bet, but if there is another simple way, please drop me some lines about it. Thanks you all for the comments. (PS: All these problems will vanish as soon as my new Green z10+zVM+zVSE pack arrives) Atenciosamente, João Carlos R.

I guess the original question was vague enough that we can't help much more... If you erased the file and believe it is still on disk, and you did not touch anything on the disk yet, then flipping the directory may be all you need to do. But when things happened already, you're looking at reading all blocks from disk and then arrange them in the right order to construct relevant parts of the original file you lost. That's been done, but it is not something for the novice plumber. And this may not be the time where you want to build those skills. Maybe you should describe your problem a bit more detailed so we can find a shortcut. Rob
