       _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  geo-
       graphic coordinates associated 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-button  menu  is  pre-
       sented  so  the user knows which mouse buttons to use. The
       output is always printed to the terminal  screen;  if  the
       output  is  redirected  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 pro-
	      grams 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


   PPaarraammeetteerr::
       sspphheerrooiidd==_n_a_m_e
	      Name  of a spheroid (for latitude/longitude coordi-
	      nate conversion).
	      Options:	australian,  bessel,  clark66,	 clark80,
	      everest, international, wgs72, wgs84


NNOOTTEESS
       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 run-
       ning _d_._w_h_e_r_e. The _-_d flag allows to optionally output lat-
       itude/longitude	coordinates  pair(s)  in  decimal  degree
       rather than DD:MM:SS format. In other projections the flag
       is silently ignored.
