    SETSYMBOLSIZE

    Purpose: Sets the symbol size of a series.

    Syntax:  SETSYMBOLSIZE(series, size, item)

              series - Optional, a series. Defaults to current window

                size - An integer, the symbol size in pixels.

                item - Optional, an integer. The series number if the 
                       target is a Window with more than one series.
                       Defaults to 1.

    Returns: Nothing, sets the symbol size of a series.

    Example:
             W1: 1..20;setsym(14);setsymbolsize(9)

             W1 contains a 20 point series where a circle is used as a 
             symbol and the size is set to 9.


    Remarks:
             The SYMBOLSIZE is specified in terms of pixels.

             If size <= 0, the size is set to the SYMBOL_SIZE configuration 
             parameter.
