ABSTRACT:
A iconic programming system process represented by a directed graph of icons and connections. When a user starts execution of the iconic system, the system first separates the icons into a list of threads starting with icons at the highest level of the graph. Icons at lower levels of the graph, such as icons within subprograms or virtual threads, will be placed on a thread when the subprogram or virtual thread is started. Virtual threads contain all icons connected to the output of an iteration icon. Each thread is processed by selecting a start icon, or by randomly selecting an unconstrained icon if no start icons are present. Processing continues by processing each icon which has all data input available. Each of the threads is processed by processing one icon per thread in each cycle, until all icons have been processed.
