I should have been more specific, it should be both usable on another platform (i.e. documented) and able to be transferred back to z/OS. I searched some old threads, I didn't test it but there is a suggestion that BINARY TYPE E MODE B works for a round trip transfer. Is the resulting format documented anywhere? I transferred some data and compared to data transferred with the RDW, from what I can see: - the 4 byte rdw (2 bytes length) is replaced with a 3 byte field - the length is the length of the data without rdw i.e. 4 bytes less than in the RDW - the first bit in the 3 bytes is set, I don't know what it means. z/OSMF can also transfer VB data using REST services, it uses a different format again. The length field is 4 bytes and is the data length only. According to the documentation a round trip should work. I've seen another example (I can't remember the product) which used the RDW format, except that the length was little endian. > FWIW, you can do it easily with Co:Z SFTP. Yes, Co:Z SFTP works well. Unfortunately it isn't available at all sites. -- Andrew Rowley Black Hill Software ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
