I have downloded a package for displaying Bode-diagram and placed it in the application directory. It says that I could load it with
Mathematica 4.0 write this:
From In:= LaplaceTransform::obslt: All LaplaceTransform and InverseLaplaceTransform functionalities are now autoloaded. The package Calculus`LaplaceTransform` is obsolete.
From In:= Needs::nocont: Context Calculus`LaplaceTransform` was not created when Needs was evaluated.
I have no idea what I do wrong...
