Everything works the way it should.
octave> mod(5,5)
ans = 0
octave> mod(6,5)
ans =  1
octave> mod(7,5)
ans =  2
octave> mod(5,5) == 1
ans = 0
octave> mod(6,5) == 1
ans = 1
octave> mod(7,5) == 1
ans = 0

Now I’ll just enter the loop code:
octave> for i = 1 : 11
>  fprintf('%4d', i);

   1
   2   3   4   5   6
   7   8   9  10  11

Very strange! Now everything works the way it should. There must be gremlins in 
my computer! And my original code that inspired all this works correctly as 
well. Apparently I just needed to restart Octave or the computer.
