I'm fairly new to Octave.  I've figured out how to pass command-line
arguments to a script, but only if that script is an executable script or

Is there a way to do so from the Octave console?  When I am at the Octave
prompt and type "myscript arg1 arg2" I get "error: invalid use of script in
index expression."  I'm using Octave 3.2.4 on a Windows 7 64-bit laptop.

Here is the script that I have so far:
% Display command line

printf('%s; %d arguments\n', program_name(), nargin);
arg_list = argv();
for i = 1:nargin
     printf('%d argument = %s\n', i, arg_list{i});


I am really not sure if I understood what you want. But what about
system("octave myscript.m a b")

at the octave command prompt?

Well, that works, but the value of arg_list (or any other variable, I'm guessing) isn't available to me after the script terminates. It seems to me (again, perhaps naively) that one primary reason for using the console in the first place is to be to be able to go in after a script runs and examine the values as a debugging step.
