The ORGANIZATION specifier indicates the internal organization of the file. It takes the following form:
|'SEQUENTIAL'||Indicates a sequential file.|
|'RELATIVE'||Indicates a relative file.|
|'INDEXED'||Indicates an indexed file.|
The default is 'SEQUENTIAL'. However, if you omit the ORGANIZATION specifier when you open an existing file, the organization already specified in that file is used. If you specify ORGANIZATION for an existing file, org must have the same value as that of the existing file.
