The Local Field Clause allows you to specify local field
    definitions and record definitions within record elements.

    To improve performance, some languages and language processors
    have alignment restrictions for data definitions. The ALIGNED
    clause aligns a field or record definition on a specified
    boundary relative to the beginning of the record you are
    defining.

    Each field or record, except BIT fields, begins by default on the
    first byte following the last field. BIT fields begin on the bit
    immediately following the last field.

    The ALIGNED clause aligns fields or records within a record
    relative to the start of the record, not relative to virtual
    memory locations.

    For example, if you specify LONGWORD alignment for a field,
    that field does not necessarily begin on a longword boundary in
    memory. Rather, the field begins some multiple of 32 bits beyond
    the start of the record. To correctly use the aligned clause, you
    must know the memory alignment techniques of the language you use
    with CDO.
