Yes, but what is the problem with recfm=u? Treat it as defined/documented: physical blocks, with undefined internal logic. So don't try to find logic in it. Is this what FTP tries to do?

Each "logical record" is simply a block on DASD, with no imbedded (in the data) of where the record ends. This is a artifact of the ECKD format that only the IBM z (as far as I know) uses. AMATERSE encodes the length of each physical block actually read into its data stream. And it produces FB output. So when you send it somewhere, the LRECL is always known. AMATERSE uses the encoded data in the FB to restore the data onto disk in the same PHYSICAL format that it was unloaded, making it usable once again by DFDSS. IMO, DFDSS should just have used VB or VBS format. > > If it FTP only, what is the special problem for FTP?
