ABSTRACT:
An iconic programming system wherein each icon within the system may have zero or more data input connections, zero or more data output connections, an optical sequence input connection, and an optional sequence output connection. Each of these connections may be used to graphically connect each icon to another icon to form a network of icons that operates as a computer program. Execution of the network is accomplished by processing each icon and performing any programming functions represented by the icon. After an icon is processed, data resulting from the processing is sent to all icons connected to data or sequence output connections, and those icons are scheduled for processing. Any start icons in the network are scheduled to process first. If an icon is scheduled for processing and it does not have data available to an input, the icon connected to that input is scheduled.
