  Thanks for all the reply on the subject.
  
  I already noticed write-object and display-object. But, couldn't
  achieve my purpose. I'd like to display object information when it
  created(like in Keene's CLOS book)
  
  When I do like :
  (define my-obj (make <my-object>))
  
  want to display like :
  #[<my-object> #pafac80] has slot-a, slot-b
  
  instead of #[undefined]
  
  
  In CLOS, I can do it by defining a method of print-object. I defined
  display-object and write-object, but couldn't get similar effect like
  CLOS.

Display-object and write-object are the right generic for you to write
methods on to change an objects print behavior. However it seems you want
to change the behavior of define as well.
