推荐答案

我认为 文档很好地涵盖了这一点.

I think the documentation covers this pretty well.

固定长度记录的所有字段都具有固定长度值.例如，以下有三个字段，每个字段为 10 个字符，从位置 1、10 和 20 开始:

Fixed length records have fixed length values for all fields. For instance, the following has three fields that are each 10 characters, starting at positions 1, 10, and 20:

Name     $200.10   Comment    <\n>
Name2    $200.10   Comment2   <\n>
---------1---------2---------3

<\n> 代表行尾.

参差不齐的格式允许最后一行是可变长度的:

A ragged format allows the last line to be variable length:

Name     $200.10   Comment<\n>
Name2    $200.10   Comment2<\n>
---------1---------2---------3

这是一种在其他固定长度数据中具有可变长度字段的方法.这通常用于评论，是一种节省空间的方式.

It is a way of having a variable length field in otherwise fixed length data. This would typically be used for comments and is a way to save space.
