http://www.sbcl.org/manual/ WebCommon Lisp is a programming language that is largely used interactively using an interface known as a REPL. The REPL (Read Eval Print Loop) allows one to type code, have it evaluated (run) and see the results immediately. The prompt for the REPL (at which point one types the code to be run) is indicated by CL-USER>. lightning shop near me
