Apparatus for generating graphic symbols on a cathode-ray tube employs a beam control system which starts each of a plurality of parallel strokes required for each symbol at the bottom, using a programmed offset for symbols which extend below a baseline, and to otherwise move a symbol in the X and Y axes from a position routinely specified as spaced symbols are displayed in a line. The slope of the strokes for a symbol is controlled for italicizing the symbols by programming the relative magnitudes and signs of inputs to X and Y integrators which generate ramp signals added to symbol positioning signals. The beam is turned on and off during each stroke in response to a programmed and clocked bit stream of coded digital signals. The size of a symbol is controlled by programming the clock rate for the beam on-off control and the magnitudes of the inputs to the X and Y integrators.
