How does the file structure in ScienceDirect work?
Block mode —The file is sent as a series of data blocks. Each block begins with a 3-byte header containing some descriptor flags and a 2-byte length field giving the block byte count. Flags are used to indicate EOR, EOF, and restart. Compressed mode —Rarely supported today because modern compression methods have superseded this primitive function.
How is the record structure of a file set?
Record-structure, rarely used today, means that there is a record format to the file and is set by sending the STRU R command to the other host. Even when the record-structure is set for the transfer, the actual formatting of the data depends on another setting—this one is called the transmission mode.
