Subject: Re: rubyw, RuntimeError, capturing the stack, FXRuby

begin
  puts 1/0
  rescue  Exception, NameError => e
  print "this is an error [#{e}]"
  print $!.inspect #Ruby places a reference to the associated Exception
object into the global variable $!
 end 

output: this is an error [divided by 0]#<ZeroDivisionError: divided by 0>
