Need help figuring out how to save values

Hi. I have a task where I am to call a function multiple times, and I'm not allowed to include any arguments. The code should keep track of how many times it's been called, i.e. the first time the function is called, I should be able to retrieve the value 1, the second time, value 2 etc.

Also, I need to save, each time the function is called, a value that can be accessed the next time that "instance" of the function is called.

For example.

for i = 1 : 10
  for j = 1 : 10

       abc = Test();

    end
    end

and then, in the Test function:

% getting hold of j, without it being included as an argument

% save j+1

% the next time j = 1, I should be able to retrieve j+1, and then save another value etc

Thanks a lot in advance :).
