write a list of variables to a file, formatted

[Daniel Barna <daniel.barna@...>]

Hi, I have a function which return a list of variables:

function some_function()

  return a,b,c,d;

end

I would like to write this to a file, using a whitespace as the separator, something like this:

some_file:write(some_function());

How can I do this?

Thank you

Daniel
