NNAAMMEE
       rr..rruunnooffff (G-language) Generates an SCS curve number runoff
       map layer. It is a command-line interface  for  generating
       the runoff map by the SCS method.

       rroo==_m_a_p output runoff map name  in *100 mm

       The  command-line  ordering  can be in any  form  but  all
       key words must be there to run the program.

NNOOTTEE
       The _r_._r_u_n_o_f_f program is sensitive to  the  current  window
       setting.   Thus	the  program  can  be  used to generate a
       runoff map of any sub-area  within  the	full  map  layer.
       Also, _r_._r_u_n_o_f_f is sensitive to any mask in effect.
