run octave script from command window with variable length arguments

I have a octave script (script.m) file with the following code:

if length(argv()) > 0
     s = argv(){1};
else
     s = "";

In octave command window, pwd is set to the script directory. From command window, how can I run script.m with one, two or no arguments?

I am using Octave (GUI) in windows.

An endif is missing at the end but here we go:

if length(argv()) > 0
  s = argv(){1};
else
  s = "";
endif
s

With no argument:

$ octave script.m
s =

With one argument:

$ octave script.m foobar
s = foobar

With two arguments (the second goes to nirvana because you don't use it in your script):

$ octave script.m foobar baz
s = foobar
