I don't think most Lisps provide a way to save stuff entered at the repl. Generally a Lisper uses Emacs + Slime, which makes it easy to type code into another buffer and load it into your running Lisp, or some Lisp IDE that provides the same thing.
Some Lispers like to do their exploratory programming at the repl and have come up with programs that will save what you type, but I don't remember the program names or who's written such a thing since I don't do that. Google around and you may find it, but it's presumably too late for whatever you have typed thus far.

That's a terrible choice. It provides no way to put code into your Lisp and is completely ignorant of Lisp formatting, has no debugger integration, no auto-completion, does not provide automatic lists of function parameters, has no online documentation, and no definition lookup. It doesn't come with CL syntax highlighting either, if you want that.
