I am just beginning to learn LISP and I'm looking for a LISP compiler/interpreter that I can download and install (an environment in which I can practice programming in LISP). Can anyone point me in the right direction? I have Windows XP.
I recommend ClozureCL. There are many good and free lisps but most of them are for Unix. For Windows there are only two: Clozure and Steelbank. Since Steelbank for Windows is still in beta state there is only Clozure left. CLisp isn't a very good choice imo. Its terribly slow and it seems to have a lot of issues.
LispIDE is very basic but easy to use. Its a good start for a beginner. And it works with Clozure.
