- 'I've written up a little program that calculates prime numbers, starting
- 'with 2 and going as far as you want. I've included it in this message,
- 'along with the first 2000 prime numbers. If anyone finds this useful,
- 'feel free to take it. And if anyone has any suggestions on how to make
- 'what I've written faster or smaller or otherwise better, please let me
