When a sign is provided, if the highest-order bit of the data is ON (1), a "-" minus sign is used,
and if the bit is OFF (0), a "+" pulus sign is used. The value (decimal) is expressed two's
complement notation. (A two's complement number is obtained by inverting the 0s and 1s in a
binary number and adding 1.)
Note: If a registration number has not been used yet, the data for the next registered number will be
brought forward.
