It seem to be quite obvious that you should reorganize your code (everything
that makes up the 'calculation'), so that you have a simple function that
will accept e.g. the filename to work on an the directory to save the
resultas as arguments. Then the body of your loop will only contain the
call of this function for various arguments. If you want to keep the
calculation-code (=funtion-definition) in an extra file, I would agree with
Dave that you should save the function to a package file an load that via
Get (or make it a real package and use Needs). After all that's what
Mathematica supplies for exactly that purpose. You will find that approach
to be much easier than you might think and it will work much better and be
less error-prone than using the frontend as a substitute for basic
Whether you run the resulting Get + Do within the frontend or use the
mathematica-kernel only to do the job is another story...

If you really want to use the FrontEnd (which again, I would not recommend)
you can use a combination of NotebokOpen, SelectionMove/NotebookFind
and SelectionEvaluate to achieve what you want. The following would be a
If you need help on this, you should post the code you are using to 'call a
notebook' and you might find people to be able to help you much better...
