 Indicates the internal organization of the file.  It takes the
 following form:

 ORGANIZATION = org

 org  Is a character expression with one of the following 
      values:

 'SEQUENTIAL'          Records are stored in the order that 
                       they are written. Access mode must be 
                       sequential, append, or direct (fixed-length 
                       records only). (*DEFAULT FOR NEW FILES*)

 'RELATIVE'            Records are stored in numbered positions. 
                       Access mode must be direct or sequential.

 'INDEXED'             Records are stored according to the values 
                       of their keys. Access mode must be indexed 
                       or sequential.

 The default for an existing file is its current organization.
