                              "literal"
                              EXTERNAL externalfile
        ORGANIZATION IS RECORD SEQUENTIAL

Syntax: for Format 2

       ORGANIZATION IS RECORD SEQUENTIAL

Comments:

Donot code the SELECT verb in your syntax.
Do not use ellipses to continue a FILE-CONTROL clause on subsequent lines. Any keyword except /* (the comment keyword) designates the end of the continuation.
Code an IO keyword for each file.
AMB generates both the program INPUT-OUTPUT section header and the FILE-CONTROL header.
Format 1 supports COBOL, as follows
- Dataname can be a drive, path identifier, or both.
- EXTERNAL identifies externalfile to the external environment for further mapping to an external file-storage environment name.
- Externalfile specifies the environment variable. The SET command defines the environment variable; the Runtime system uses it to locate externalfile in the environment.
- "Literal" is a standard PC file specification.
- ORGANIZATION is RECORD SEQUENTIAL, a fixed length record (default).
