Hi Alain,

Thanks for the tips. I tried with /run, but it didn't work. Actually, the
modified povray code works fine under mac os x. Since it has some issues when
recompiling on intel cpu, I ported to windows platform.

Here is the command line used for mac os x version which runs as expected:
      unix/povray -Itest.pov +W800 +H600 +FN +Linclude &>/dev/null

On windows, I used the following command in the for loop:
      povwin.exe -Itest.pov +W800 +H600 +FN +Linclude /render /exit >null

But when even frame is finished, it still waits for me to press the "run" button
to render the next frame again. Can you please correct me?
