       _d_._r_a_s_t_._n_u_m overlays cell category values onto a raster map
       layer  displayed to the user's graphics monitor.  Category
       values will be displayed in white and/or black,	based  on
       the  colors  in	which  underlying cells are displayed.	A
       grid outlining each map cell will also be  overlain  in	a
       user-specified color.


       The  user  should  run  _d_._r_a_s_t  to display the desired map
       layer on the graphics monitor before running this program.


       _d_._r_a_s_t_._n_u_m  can be run non-interactively or interactively.
       If the user specifies the map whose category values are to
       be  displayed  and/or  the grid color on the command line,
       the program will run non-interactively.	Alternately,  the
       user  may  simply  type dd..rraasstt..nnuumm on the command line; in
       this case, the program will prompt the user for	parameter
       values  using  the standard GRASS user interface described
       in the manual entry for _p_a_r_s_e_r If no grid color	is  given
       the  default  will be used.  If no map layer is specified,
       the program will use whatever raster  map  layer  is  cur-
       rently displayed in the active frame on the graphics moni-
       tor.

       mmaapp==_n_a_m_e
	      Name of existing raster map  layer  whose  category
	      values will be displayed.
	      Default:	 (whatever  raster map layer is currently
	      displayed)

       ggrriidd__ccoolloorr==_n_a_m_e
	      Color in which an overlain grid will be  displayed.
	      Options:	 white, red, orange, yellow, green, blue,
	      indigo, violet, magenta, brown, gray, black
	      Default:	gray


NNOOTTEESS
       The user is advised to set the current region to  a  rela-
       tively  small  area  (i.e.,  less  than	100  rows  by 100
       columns); otherwise, the individual cells being	displayed
       will  be small and the category value associated with each
       will be difficult to see.
