Simple Beginner Question

[Jeffrey Edgington <Jeffrey.Edgington@bea.com>]

Once a function is defined:

   (define foo (lambda (x) (* 3 x)))

How do I print what the definition of "foo" is?
If I try:

   (display foo)

DrScheme returns:

   #procedure foo    (or something similar)

What function do I call so that I can see the text of the
definition?

Thank you,
