COMMAND NAME:

        COPY

USAGE:
        COPY SIGNAL <sig_name_pos> <sig_name_pos for new sig> <name>
        COPY AREA <sig_name_pos> <first point of area> <second point>

        This command is used to copy entire signals to other locations
        as well as to copy portions of the signals themselves.
        Useful for reducing the number of edits by duplicating similar 
        waveforms and then making minor modifications.

        SIGNAL:
        Copy a signal <sig_name_pos> to another location <sig_name_pos for new
        sig>. Either signal location may be specified via a signal name or
        number using the keyboard OR by position using the LEFT MOUSE BUTTON. 
        Signals may be copied directly above, directly below, or in between any
        of the existing signals.

        AREA:
        Select a signal via a signal name or number using the keyboard OR by
        position using the LEFT MOUSE BUTTON. Then select an area of the
        signal by specifying two points with the LEFT MOUSE BUTTON. The segments
        contained in this area will immediately be appended to the end of the
        signal.  The last state of the signal must be the same as the first
        state in the area being appended for this to work.

        NOTE: COPY AREA cannot be used in a script.
