MAJOR_MINOR

       Causes DEC DATATRIEVE to use MAJOR_MINOR alignment when storing
       or retrieving data in a data file. MAJOR_MINOR forces word
       boundary alignments according to data types for elementary fields
       defined with the SYNCHRONIZED clause and forces group fields
       to the maximum alignment of the elementary fields they contain.
       MAJOR_MINOR is the default for DEC DATATRIEVE.

    ALIGNED_MAJOR_MINOR

       Causes DEC DATATRIEVE to use ALIGNED_MAJOR_MINOR alignment when
       storing or retrieving data in a data file. ALIGNED_MAJOR_MINOR
       forces word boundary alignments according to data types for all
       elementary fields in the record and group fields to the maximum
       alignment of the elementary fields they contain.

    LEFT_RIGHT

       Causes DEC DATATRIEVE to use LEFT_RIGHT alignment when storing or
       retrieving data in a data file. LEFT_RIGHT forces word boundary
       alignment for elementary fields defined as COMP, COMP_1, COMP_2,
       and DATE.
