       _d_._w_h_e_r_e is an _i_n_t_e_r_a_c_t_i_v_e program  that	allows	the  user,  using  the
       pointing device (mouse), to identify the geographic coordinates associ-
       ated with point locations within the current geographic region  in  the
       active display frame on the graphics monitor.


       If  the	user runs _d_._w_h_e_r_e without specifying the name of a spheroid on
       the command line, each mouse click will output the easting and northing
       of the point currently located beneath the mouse pointer.  A mouse-but-
       ton menu is presented so the user knows which mouse buttons to use. The
       output is always printed to the terminal screen; if the output is redi-
       rected into a file, it will be written to the file as well.


       Mouse buttons:

	    Left:   where am i
	    Middle: draw to/from here
	    Right:  quit this

       The left mouse button prints the coordinates at the selected point, the
       middle mouse button allows to query two points (they are connected by a
       line for convenience). By using the right mouse button  the  module  is
       left.

   FFllaagg::
       --11     Only one mouse click is executed.
	      This  option  is	provided  for shell scripts and programs which
	      want to obtain only one point from the user. The output is  only
	      written to stdout, unless redirected into a file. The geographic
	      location and mouse button pressed are output.

       --dd     Output lat/long in decimal degree

	      Name of a spheroid (for  latitude/longitude  coordinate  conver-
	      sion).

	      tional, wgs72, wgs84

       This program uses the current  geographic  region  setting  and	active
       frame.	It  is not necessary, although useful, to have displayed a map
       in the current frame before running _d_._w_h_e_r_e.  The  _-_d  flag  allows  to
       optionally  output  latitude/longitude  coordinates  pair(s) in decimal
       degree rather than DD:MM:SS format. In other projections  the  flag  is
       silently ignored.
