forward command

    (A) Function
        Updating a simulation image as putting simulation time forward.

    (B) Format

        forward  [ <stop  time> ]

    (C) Parameter
        <stop time>
          Designate simulation stop time.
          Use an unsigned integer or a +-signed integer. In the case of 
          a +-signed integer, the simulation stop time is the current 
          simulation time plus the time given by the integer here. 
          However, when the time specified in the stop command comes,
          the simulation stops.
          If <stop time> is not specified, the simulation stops 
          at the time specified in the stop command. 

    (D) Notes
        If a SIGINT/SIGQUIT signal (normally, given by pressing the ^C and ^\ keys) 
        is issued, the simulation stops before the simulation stop time. 
        (Even in this case, the simulation image keeps a stable state that 
        has been achieved just before the clock input.)
