It connects to a ms access database, retrieves the F_name column data from the Bowlers table and then iterates through it with a reader storing the data in a variable named FName. Strangely, it doesn't seem to do anything with the var, nor return it. Unless I am missing something it isn't doing anything permanent. Even if it did something with the FName variable, it would only have the value of the last row in the dataset.
