# _array_structure.byte_order

Name:
`'_array_structure.byte_order'`

Definition:

            The order of bytes for integer values which require more
                   than 1 byte.

                   (IBM-PC's and compatibles and DEC VAXs use low-byte-first
                   ordered integers, whereas Hewlett Packard 700
                   series, Sun-4 and Silicon Graphics use high-byte-first
                   ordered integers.  DEC Alphas can produce/use either
                   depending on a compiler switch.)

Type: ucode

Mandatory item: yes

The data value must be one of the following:

`big_endian` | The first byte in the byte stream of the bytes which make up an integer value is the most significant byte of an integer.

`little_endian` | The last byte in the byte stream of the bytes which make up an integer value is the most significant byte of an integer.
