   Parameters:
       map=name

DESCRIPTION

       d.rast.num  overlays  cell category values onto a raster map layer displayed on the user's
       graphics monitor.  Category values will be displayed in the text color given and scaled to
       fit  within a single cell. A grid outlining each map cell will also be overlain in a user-
       specified color, unless it has been set to "none".

       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 monitor.

       If the -f flag is given the displayed number will take on the color of  the  base  map  in
       that cell.

NOTES

       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 individual cells being displayed  will  be  small
       and  the  category value associated with each will be difficult to see.  No data cells are
       indicated with "Null".
