Why does that make sense? Files on Unix, Linux and Windows are stored as a byte stream and the applications that write and process them do not know or care what the underlying sector size is. Do you mean BLKSIZE=512? That is quite inefficient, wasting over half of the space on each track. AFAIK LRECL has no meaning for a RECFM=U data set. Once you get these ASCII data to the mainframe in a RECFM=U data set, what would you do with them? -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
