I have 2 iSeries (AS/400), one running V6R1 (production) and the other running V4R4 (testing/backup). I have legacy S/36 programs that I still use and modify. I need to be able to regularly transfer all QS36F files from the V6R1 machine to the V4R4 machine for testing and backup (in the event of a catastrophic problem with the newer iSeries machine). V4R4 is not included as an option for the 'previous release' parameter on the SAVLIB command on the V6R1 machine. What is the easiest way to transfer these files to the QS36F library on the V4R4 machine so they can be used on that machine with the programs that run in S/36 mode? I've heard that FTP can be used, but I don't know how to handle the S/36 indexes.
