1. A responsive system for digital processing comprising:

  • a data transmission unit; and

    a plurality of data processing units communicating with one another through said data transmission unit via messages wherein each message comprises at least one signal, said data processing units implementing at least one computer program dependent on a respective update status, the system being configured as follows;

    a) each of said data processing units, during each communication, assigning a revision identity to each signal within a message produced by said data processing unit to characterize said respective update status of said each signal;

    b) one of said data processing units receiving the message performing a comparison to determine if the revision identity characterizing each signal within the received message matches a revision identity stored for that signal; and

    c) said one of said data processing units receiving the at least one message, performing said at least one computer program on a signal within the message upon matching the received revision identity with the stored revision identity and otherwise not performing said at least one computer program on the signal.
