problem with inp_par.F

first: I believe that in

      WRITE(stdout,*) 'MyRank = ', MyRank, Iname

it should be Cname instead of Iname.

second: this version doesn't work for me. Instead it works if I add:

      DO ng=1,Ngrids
        CALL mp_bcasts (ng, model, Cname, 80)
      END DO

right before the OPEN command.

Is that correct?
