Hello, World! in Lisp

Example for versions Corman Common Lisp 3.0, SBCL 1.0.1, SBCL 1.0.29, clisp 2.47, gcl 2.6.6

When executed in interactive mode, program output looks as follows:

Hello, World!
NIL

First line contains standard output, second — the result of expression evaluation (in this case there is none). 

(format t "Hello, World!~%")
