GPOINT

     GPOINT is the grid location to be used for the plot.  The value can 
     be entered in the following ways:

        1.  station numeric or character identifier

        2.  a latitude and longitude pair separated with a semicolon
 
        3.  @ followed by a grid x and y coordinate pair separated
            with a semicolon. The grid x and y coordinate pair will not
	    change even the navigation is changed.

	4.  a CPF file name with optional path.  The CPF file must
	    contain only one valid latitude/longitude pair.
	    
	5.  Graphically using the CURSOR command.


     If necessary, the grid data will be interpolated using a 
     bilinear interpolation to the point specified.

     Examples:

	GPOINT	=  @1;1.5	Grid point (1,1.5)

	GPOINT	=  30;-120	Grid point at 30 latitude and 
			        -120 longitude

	GPOINT	=  5;5	        Grid point at 5 latitude and 
			        5 longitude.  Note that this is 
			        probably an error and the input 
			        should have been @5;5

	GPOINT	=  BWI	        Point located at Baltimore-Washington
			        International Airport.

	GPOINT	=  nmap2.cpf    CPF file containing a valid latitude
				longitude pair.
