Save a binary VB file (including RDW) from non-zOS file system, as a binary VB file in zOS without adding new RDW

Question

I have downloaded a VB binary file from zOS, with RDWs but without BDW.

When I try to send it back it treats the existing RDW as part of the data and adds new RDW.

Is there a known way to do it, except editing it manually?

Answer 1

Switching the ftp transfer mode to block mode should do what you want:

quote mode b

You may, or may not need the quote prefix, depending on your ftp client. Also, since you want the data set on z/OS to be RECFM=VB, you might need to tell the FTP server:

quote site recfm=vb lrecl=nnn

Where nnn is the maximum record length plus 4.
