This parameter defines whether RECFM=VB BDW (Block Descriptor Word) is maintained when sending or receiving files. This parameter must only be specified when the file being transferred is in RECFM=VB format. The BDW and the RDW (Record Descriptor Words) are maintained when sending data to a remote system or receiving data from a remote system. If the data being sent or received is not in the proper BDW/RDW format, the transfer fails.
