Thanks for your comments! In Matlab for example, the loop index
variable stays on the last number, in this case 5, I guess that's how
I confused it in first place as I'm used to Matlab. I used the loop
index variable for testing in my program, not to be in there, that's
how I came across the whole situation. But, I guess I will have to
follow your advice Paolo..
