How do I export the results of multiple 'runs' of my code to text without overwriting the previous run?

I have been playing around with different parameters in my code and want to collect the results of all of this in one single text file. But each time I print the results of a specific run of my code with specific parameters it overwrites the last one. Is it possible to have one single text file that collects the results of each run of my code so that I can see on one page a list of results with their corresponding parameters?

What are you using to write the data? If you look at

doc fopen

You can see the 'a' option for append.
