I've tried it. It doesn't do anything useful. I agree with the OP that the
implementation fails its apparent intended objective; I call it moronic.
But I fear a PMR would be ineffective. I imagine replies:
o The documentation says that on a transfer the RDWs are treated as
part of the data and appear in the data in the destination file. So
on a GET the RDWs appear in the data of the file gotten to; in
a PUT the RDW images in the source file appear in the data of the
destination file. ∎; WAD.
o In any case, changing it now would probly break existing code.
o Treating 4 bytes of a record when the server has no control over the
source data might cause serious I/O errors or buffer overuns.
If the OP hasn't access to z/OS, his interest must be only academic.
I'll suggest the alternative sequence from the remote system:
BINARY
QUOTE TYPE E
QUOTE MODE B
There is no equivalent possible with a z client and a non-z server.
(Others might suggest QUOTE STRU R instead.)
