MSC: struct xycoord far _moveto( short x, short y )
	 MSC: struct _wxycoord far _moveto_w ( double wx, double wy )


	- prototype in graph.h

	- moves current drawing position to specified coordinates
	- returns previous coordinates in the following structures:

	struct xycoord		struct _wxycoord
	    {			    {
	    short xcoord;	    double wx;   	- window x coord
	    short ycoord;	    double wy;   	- window y coord
	    };			    };
