Subject: Re: 'require' is not recognised

thanks for your help - I had forgotten to include benchmark inside 
quotes so it wasn't picking it up.
one more quick question...

require'benchmark'
iterations = 100000
a=Benchmark.measure do
 for i in 1..iterations do
  x=i
 end
end

In the above code (from Beginning Ruby book)
what's the difference between benchmark and Benchmark(uppercase)
Also why 2 periods 1..iterations?
