COMMAND NAME:

        HISTORY

USAGE:
        HISTORY number-of-ticks

        This command sets the waveform history length for the Display
        Analyzer when simulating with the simulator and the Display
        Analyzer running concurrently.  "Number-of-ticks" is an integer
        which specifies the length of the history in ticks.  The
        default value of history is 10000 ticks.  This feature provides
        a mechanism for controlling the process size of the Display
        Analyzer.  The shorter the history, the smaller the process
        size.

        Note that this command has no effect on the simulator itself.
        The simulator records the values of all open signals and 
        memory locations in the binary activity file for the whole
        duration of the simulation.  This activity data can 
        subsequently be read into the Display Analyzer running in
        stand-alone mode using the Display Analyzer's RECALL command.
        In this mode the Display Analyzer loads the entire history of
        the simulation.
