running a program

[revit]

I want to run a program several times , for example some thing like that:

for i=1 to 200
run program input${i}.txt $i > out$(i+1).txt
done


(i is an argument to the program)
how do i write it correctly?
thanks

for((ii=1, jj=ii+1; ii<200; ii++, jj++));
do
program input$ii.txt $ii > out$jj.txt
done

its a bash script, i don't know for another shells.
