How to compile a file in "Expect"?

I am using a user interface menu which is using Expect files to开发者_如何学Python display messages. In an attempt to add a menu item I had to change one of these file, however, it seems to me that the changes are not getting reflected. Do we need to compile this file?

Expect uses an interpreter for its scripts, there's no need to compile them. If your change is not producing the result you want you should post details of the code.
