Please use turbo mode Press the green flag and enter a number.I recommend starting with 100000, for higher numbers it will get much slower. Press space to hide/show the variables and lists.Hiding the lists make the program a lot faster. It can generate all the primes up to 100000 in 5 seconds! That is pretty fast! :D
Detailed explanation coming soon... UPDATE!! made it twice faster! (skipping even numbers) I still need to improve some things...
