Charles,

I was prepared to be disheartened when I saw that David had responded  
ahead of me, but I have a solution!

$ irb -f --noprompt -rprimes
a=Primes.new
#<Primes:0x1d5084>
a.show_primes(1_000_000, 1_000_100)
1000003 1000033 1000037 1000039 1000081 1000099 1000001
exit

Since your commands didn't show the typical prompts from irb, I went  
poking around and came up with this.   The '-f' suppresses the  
~/.irbrc (which I have), --noprompt ought to be obvious, and -rprimes  
requires the primes.rb file with your original Primes class definition.
