Hey guys, I have a method as such:

def random(len)
  if len !~ /\d+/
    pub_send "Invalid number"
  elsif len > 30
    pub_send "No more then 30 chars"
  else
    chars = ("a".."z").to_a + ("A".."Z").to_a + ("0".."9").to_a
    random = ""
    1.upto(len) { |i| newpass << chars[rand(chars.length)] }
    pub_send random
  end
end

and i call the method like so..

random($1) if $msg =~ /^rand (\d+)/

the value of $1 will always be a number, but it seems when i am passing
it to the function it returns an error saying it cannot compare len to
30 because the value of len is a string... Any ideas?

Thanks in advance
