How 'bout corrected first?  Guess my last post is a perfect argument in 
favor of my learning how to use test units.

Corrected code be here:

$usage = "Usage:"

def print_usage(val)
  if val=="exit"
    print $usage
    exit
  else
    print $usage
  end
end

if ARGV!=[] and !(ARGV.length > 2)
  begin
    arg0, arg1 = ARGV.map{ |n| Integer(n) }
    if (arg0 < 0) or (!arg1.nil? and (arg1 < 0))
      print_usage("exit")
    elsif !arg1.nil? and (arg0 > arg1)
      print_usage("exit")
    end
  rescue ArgumentError
    print_usage("exit")
  end
else
  print_usage("exit")
end
