Abstract: A data composing, editing and formatting system for use in business offices by typists and composers of business letters and documents. A cathode-ray tube display is utilized to display keyed data and data inputted by a secondary media reader in a manner analogous to the display of a page of typed data on a typewriter. Once the data is so inputted, additional data can be inserted at a point defined by the operator without any resulting loss of information, word integrity, columnar definition or paragraph designation. Additionally, data can be deleted and the data located down page from the deleted data will shift up page to fill in where the deleted data was located without loss of paragraph designation. Text modification controls further include data centering within defined margins, transfer of data from one page position to another without loss of data or paragraph definition, automatic adjustment of the data to conform to new margin settings and a unique hyphenation operation. Once the data has been inputted and modified, it is transferred to a serial printer and/or a secondary media recorder for permanent recording. Special controls effect the optimum utilization of the serial printer by utilizing margin stop locations of the displayed data as well as tab stop location to define printer tabulation operations.
