How do you transfer a binary file via Connect:Direct NDM?
Off the cuff...Try changing RECFM=VB to RECFM=U and specify a BLKSIZE= instead of a LRECL=
This is really not all that different from how executable load modules are stored on the mainframe except you don't want the file to be a PDS dataset. I'm not at my office right now and I think I have some examples of NDM that transmit load modules that I can look-up if this suggestion doesn't work but I think it will.
Give this suggestion a shot and if it still doesn't fly let me know.
