Well, then, look up the examples in the documentation:
(info "(elisp)Interactive Examples")
For your function it is really simple:
(defun my-replace nil "doc-string"
(interactive)
(while (re-search-forward "<DF>" nil t)
(replace-match "ß" nil nil)))
The more complex uses of "interactive" allow you to specify how your
commands gets its arguments, i.e. prompting the user for a file,
buffer or just some text, giving it a (numeric) prefix argument etc.
HTH,
