In the OP's situation, both endpoints are z/OS, so the middleman needn't
understand the format; it should be just bits to him.
Now that TERSE is becoming a base z/OS facility, it should be made an
option of FTP to save a separate job step:
LOCSITE TERSE

I did "HELP LOCSITE" with z/OS FTP client. It tells me:
RDw RDW from VB/VBS files is retained as data.
NORDw RDW from VB/VBS files is discarded as not data.
Sigh. Too literally true. What I observed was that on PUT the RDWs
were transmitted as if they were data. On GET, they were treated as
data, not as RDWs. Didn't any coder or design reviewer or whatever
have the guts to say to the specifier, "The way you describe this is
probably not what the customer needs."?
