for loop

[houbahop]

Hello,
I have seen a lot of way to use the for statement, but I still don't know 
how to do:

for i=morethanzero to n
or
for i= 5 to len(var)

of course I kno wthat I can use a while loop to achieve that but if this is 
possible whith a for one, my preference goes to the for.

regards,
Dominique.
