If the file begins with a delimiter, the node treats the (zero length) file contents preceding that delimiter as a record and propagates an empty record to the flow.
如果文件以分隔符开始，则节点将该分隔符之前的(零长度)文件内容视为一个记录，并向流传播一个空记录。
Multiple Record Detection policies (Whole File ,Fixed Length, Delimited, Parsed Record Sequence) are supplied which determine how the input file's content should be handled by a message flow.
提供了多记录检测策略（WholeFile、FixedLength、Delimited、ParsedRecordSequence），这些策略确定消息流应该如何处理输入文件的内容。
A rectangular file is one which contains the same number of card-images or the same physical record length for each respondent or unit of analysis.
一个长方形档案中，每笔受访者的记录或是每个分析单位都包含相同的卡数或是相同的实体记录长度。
The length, in bytes (i. e. , columns ), of a logical and physical record in a logical record length formatted file.
逻辑记录长度格式档案中每个逻辑与实体记录长度，以字节（即字段）为单位。
Thus, when the data for each case or unit of analysis is stored in a single physical record, the file structure is called "logical record length."
所以当每笔数据或是每一分析单位被储存在一笔实体记录时这种档案结构就称为”逻辑记录长度”。
In order to give such a file a common physical record length, short logical records are typically "padded" with blanks so that they will all be the same physical record length.
为了让这种档案有一个相同的实体记录长度，短的逻辑记录会用空白填补，因此他们的实体记录长度相同。
