ABSTRACT:
In a word processor a string of characters entered serially via a keyboard into a plurality of positions are centered about a particular point on a line of a record medium by providing a storage medium having a plurality of addressed cells which are serially assigned to the positions on the line of the record medium, the cell addresses ranging between first and second values. The cell assigned to the position which includes the particular point receives the first character of the string while all subsequent data characters are considered as pairs of data characters. One data character of the pair is entered into the memory cell having an address one unit closer to the first value than the address of the memory cell in which the previous character was loaded and for the other data character of the pair the contents of each memory cell is shifted to the memory cell having an address one unit closer to the second value and such other data character of the pair is loaded into the memory cell in which the one data character was initially loaded. Thereafter, the contents of the loaded memory cells are serially transferred to the display device.
