I'm 99% certain that there are some "site" options in IBM FTP that will round-trip binary VB data. I've seen it discussed on IBM-MAIN, but not for years and I can't recall the details.
FWIW, you can do it easily with Co:Z SFTP. >From cozsftp client: lzopts mode=binary,linerule=rdw #or L4 works too put //hlq.binary.vb remote.file.name from remote SFTP client: ls /+mode=binary,linerule=rdw get //hlq.binary.vb local.file.name Kirk Wolf Dovetailed Technologies https://coztoolkit.com On Fri, Jan 17, 2025, at 10:45 PM, Andrew Rowley wrote: > On 18/01/2025 8:42 am, Radoslaw Skorupka wrote: > > Transfer between mainframe (z/OS) and distributed systems has never > > been an issue or mess. > > It is a mess, I submit as evidence the difficulty doing a round-trip > transfer and ending up with the same data you started with. > > Fixed length records and binary transfer is OK, anything else can be a > problem. > > EBCDIC<->ASCII translation can be a problem depending on the code pages > involved.
