--------
Bug report for Octave 2.1.33 configured for %OCTAVE_CANONICAL_HOST_TYPE%
(version of octave bundled with Redhat Linux 7.1)

Description:
-----------

The info file, under the node "Executable Octave Programs", gives an
example program:

     #! /bin/octave -qf
     printf ("%s", program_name);
     for i = 1:nargin
       printf (" %s", argv(i,:));
     endfor
     printf ("\n");



Repeat-By:
---------

Call this program "test.m" and run it with some arguments:

% test.m a b c
test.merror: lists may only be indexed by a single scalar
error: evaluating argument list element number 2
error: evaluating index expression near line 4, column 3
error: evaluating for command near line 3, column 1


A similar program is given in the node "Command Line Options".

Fix:
---

Change the printf() line within the loop to use "nth":
  printf (" %s", nth(argv,i));

and then you get:
% test.m a b c
test.m a b c
