Disclosed in an iconic programming system process for processing the icons within an iconic network. When a user starts execution of the iconic system, the system first separates the icons into a list of threads, and creates a pending queue and a done stack for each thread. Execution then starts by selecting the first icon in the pending queue of the first thread within the system, processing the icon, and placing the icon on the done stack. After all icons on the pending queue are processed, icons are removed from the done stack and a sequence signal is sent on the sequence output for the icon. If a service request is received, the subthread hosted by an active service request icon is immediately made the highest priority, and processing continues with this subthread until the subthread is completely processed.
