Are you sure? This works for me:

File: hello.lisp:

(defun hello-world ()
  (format t "hello, world"))

(hello-world)

------------

File: hello.input:

)lisp (load "hello.lisp")
)lisp (hello-world)

---------

(1) -> )read hello.input
)lisp (load "hello.lisp")

hello, world
Value = T
)lisp (hello-world)

hello, world
Value = NIL
(1) ->

----------
