Four flag bits are added to make a digital word of sixteen bits with the four added bits being equal to the sign bit. Flags are set by making their bit value opposite to that of the sign bit. The sixteen bit words are stored in a RAM memory and the presence of the flags enables ready identification and retrieval of the data.
