The FTP server was unable either to locate or to use the file determined by the XLATE statement in the FTP.DATA file. (The file name is hlq.name.TCPXLBIN unless this name was superseded by an environment variable called _FTPXLATE_name that defines a file name.) This message will be preceded or followed by another message with additional information. If FTP tracing was enabled during initialization, additional messages will precede this one with more specific detail about the error encountered. Possible errors include an invalid header record or incorrect file length. (The file must contain exactly 768 bytes of data.)
