4.2.8.1 File Organization and Access Modes
File organization is the permanent logical structure of the file. You tell the computer how to retrieve records from the file by specifying the access mode (sequential, random, or dynamic). For details on the access methods and data organization, see Table 9 in topic 4.2.1.
Note: Sequentially organized data can only be accessed sequentially; however, data that has indexed or relative organization can be accessed with any of the three access methods.
