Right.
> A binary transfer from VMS to Linux/Unix transfers the data of the records not the length fields. So you have to have some pre- or postprocessing on the VMS side. And you can't avoid this with an archiver.
Except that with Alpha-VMS the length fields are duplicated within the records. BFD is able to handle
Alpha obj files without the record length RMS field. Things are harder with VAX obj files!
As I said, I usually transfer from VMS using ftp. I was able to transfer to VMS using ar on unix and
librarian on vms.
