loop with decreasing stride

Hi,

I'm trying to plot some lag regressions and use a negative stride. What
I do is :

  do i=nlagr-1,0,8
   res@gsnCenterString = " lag "+(-i)
   plot(i/8) = gsn_csm_contour_map(wks,rlagill(i,:,:),res)
  end do

However, when I get the plots the lag is 0 , 8 , 16 and so on rather
than ... 16,8,0. I was expecting to have a decrease from biggest lag to
smallest one. Does anyone know what I'm doing wrong ?
Thanks in advance,
Ioana
