To use a sequential file that is stored on a tape device, in your ILE COBOL program, you must name the file through a file control entry in the FILE-CONTROL paragraph of the Environment Division. See the WebSphere Development Studio: ILE COBOL Reference for a full description of the FILE-CONTROL paragraph.
You name the file in the FILE-CONTROL paragraph as follows:
FILE-CONTROL. SELECT sequential-file-name ASSIGN TO TAPEFILE-tape_device_name ORGANIZATION IS SEQUENTIAL.
You use the SELECT clause to choose a file. This file must be identified by a FD entry in the Data Division.
You use the ASSIGN clause to associate the file with a tape device. You must specify a device type of TAPEFILE in the ASSIGN clause to use a tape file.
Use ORGANIZATION IS SEQUENTIAL in the file control entry when you name a file that you will access through a tape file.
