       _d_._r_a_s_t_._n_u_m overlays cell category values onto a raster map  layer  dis-
       played  to  the	user's graphics monitor.  Category values will be dis-
       played in white and/or black, based on the colors in  which  underlying
       cells are displayed.  A grid outlining each map cell will also be over-
       lain 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 currently 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, vio-
	      let, magenta, brown, gray, black
	      Default:	gray


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