I don't know what you mean with "to the length of".
There is no 'range' function. Instead the keyword 'range' is
part of the for-loop. In case of

for number range [] (0, 1, 2, 3, 5, 8, 13, 20, 40, 100) do
  write(number <& " ");
end for;
writeln;

The program actually writes the line:
0 1 2 3 5 8 13 20 40 100

So number gets all the values from the array one by one.

Internally this for-loop has some index into the array
(to the array element that is currently assigned to number).
But this for loop does not show you the index.

If you have more questions just ask.
