Saving a variable at every run

Assuming I've got to perform 10 runs and each run has 50 iterations. And there is a BestResult produced at a particular iteration in each run. I need to save these BestResult automatically at each run.

    save BestResult

However, using the above would only save for one last run by overwriting those previously saved. Perhaps if there's a way it could by itself index the file name saved, so that the previous wouldn't be overwritten?

Show us your code.

Of course, this is trivial using SPRINTF, just as the documentation shows:
