Abstract: A tabulation system for delivery to a medium of data information suitably arranged for tabulation of character series and ruled lines, and a control for controlling the data information arrangement applied to the medium. The control operates to allow the medium to sequentially deliver out control information for defining desired vertical ruled lines (columns), information regarding a horizontal ruled line (row) defining the upper side of a field between adjacent vertical ruled lines, information regarding character series to be written in the field and control commands for the writing, and information regarding a horizontal ruled line defining the lower side of the field.
