In a method of transmitting data from a transmitter (1) to one or more receivers (3), e.g. pagers, said data are transmitted in the form of a row of characters which may be received, stored and displayed in the receiver. The transmitted characters may constitute positions in a database. A line where just some positions are to be updated, is divided into a left part (4; 7) just comprising positions which are not to be changed, and a right part (5; 8) comprising at least the positions which are to be changed. Only positions in the right part are transferred to the receiver, and this takes place in sequence from the right to the left, while the positions in the left part are maintained unchanged. A second type character may additionally be transmitted, as needed, said character containing bits which may be combined with the succeeding characters such that these are caused to virtually contain a larger number of bits than the transmitted one.
