BTW, in the snippet below, Length(S) is called once or at each

Once. Since it is the start value, that is even quite logical.
However, even if it appeared in the end condition it would also be
only calculated once at the start of the loop. This is even required
for correctness, because it's possible to do something like
i := 5
for i := 1 to array_var[i] do
