Subject: Re: Making a random string

All very groovy stuff!  The final version I think I shall use is a bit 
of an amalgam of your input.

def randString(len)
  s = ""
  1.upto(len) { s << rand(36).to_s(36) }
  s.upcase
end

At one point I had "unless len < 1" but this functions the same way.

Thanks again, everyone!
