Direction coded digital stroke generator providing a plurality of symbols

A symbol generating system comprising:

• display means including X and Y deflecting means;
• X and Y up and down counters coupled to said X and Y deflecting means to develop a plurality of line segments;
• a source of direction commands for each segment for selectively controlling each of said X and Y counters to count up, count down or to stop;
• decoding means coupled to said X and Y counters and responsive to said source of direction commands to develop X and Y count up, count down and stop signals to control said respective X and Y counters so that said plurality of line segments after a first segment each start at the termination of the previous segment;
• a source of clock signals for providing clock signals of a fixed frequency coupled to said X and Y up and down counters;
• a source of segment length commands;
• and segment length control means responsive to said source of segment length commands including frequency divider means coupled between said source of clock signals and said decoding means to control the time of passing of the direction commands for each segment by said decoding means to said X and Y up and down counters to determine the length of said line segments.
