Hi
Basically, when you want to write grid data for GrADS to plot,
the fortran code should look like that: (sorry I only know how to write
fortran)

open(21,file='result.bin',status='unknown',form='unformatted')
do itime=1,time
  do ilevel=1,level
    write(21) ((result(ix,iy),i=1,x),j=1,y)
  enddo
enddo
close(21)

And the options line in your ctl file should be added that:
options sequential

If you can provide your program code and ctl files,
maybe more GrADS users can help you more correctlly.
