Start script at a chosen line

As we know it is not possible to modify a running script. You have to stop the script and restart it for the changes to become active. Now I wonder if it is possible to jump into a script at a chosen line. So one could stop a running process, make the desired changes and then have the program continue in the modified version without running the code before the changed part again.

Start you script with:
i=0;
if i==0
else
And set the "end" at the point where you want to run the script

@Alexander, that will have the same effect as commenting out code. It would also make more sense to me if you use this instead:
if false
%code that shouldn't run
end
%code that should run
That way you don't interfere with any variable that might be used in the rest of the code.

Using a method to stop and re-enter scripts at arbitrary lines would be a meta-interpreter, which runs on top of Matlab. Such a method would be prone to errors and it will be hard to reproduce the results reliably. If you want to run a code with some modifications, create a function and trigger the different methods by using a switch, e.g. controlled by an input argument.
Using structured code and functions is such a great improvement and much more stable than running scripts in dynamically modified pieces, that I cannot imagine, why somebody wants to do it the hard and complicated way.
