Click the green flag (works well in turbo mode as well) and press the space bar to start generating primes. Press the P button to pause and un-pause the calculations. Press T to get a running output of how many primes it is generating per second. Press N (preferably while paused) and a number to get that number of prime (if the list is long enough). Theoretically, it should be able to generate prime numbers up to 1 E 10. However, it has not been tested that far. Above 50,000, numbers generated are not necessarily guaranteed. The mathematical principles are sound, but rounding and use of scientific notation may cause some results to be inaccurate. Still, nearly all results should be correct. I'm just putting this disclaimer here because it's possible some are not.
Thanks to Ian Stewart's book, "Visions of Infinity" for giving me this idea. (Ian Stewart is a very good author for mathematical literature).
