Hi, I'm trying to learn Lisp on a Clisp/Slime setup.
Looking into the world of macros I try to input this macro to repl.

(defmacro Square (X) 
   '(* ,X  ,X))

Getting this answer....

READ: comma is illegal outside of backquote
   [Condition of type SYSTEM::SIMPLE-READER-ERROR]

Restarts:
  0: [ABORT] Abort SLIME compilation.
  1: [ABORT] Return to sldb level 1.
  2: [ABORT] Abort SLIME compilation.
  3: [ABORT] Abort handling SLIME request.

Backtrace:
  0: frame binding variables (~ = dynamically):
  | ~ SYSTEM::*FASOUTPUT-STREAM* <--> #<OUTPUT BUFFERED FILE-STREAM 
CHARACTER #P"/Users/arnehans/test.fas">
  1: EVAL frame for form (SWANK:COMPILE-FILE-FOR-EMACS 
"/Users/arnehans/test.lisp" T)
  2: EVAL frame for form (SWANK:COMPILE-FILE-FOR-EMACS 
"/Users/arnehans/test.lisp" T)
  3: EVAL frame for form (SWANK:START-SERVER "/tmp/slime.18994")
  4: EVAL frame for form (SWANK:START-SERVER "/tmp/slime.18994")

Leaving me clueless :-(

You want quasiquote (backquote, `), not quote ('). Unquoting only makes
sense inside quasiquoted expressions.

There are two kinds of quote '`'`'`'`'`'

You've got the ordinary kind of quote ''''''' 
On my keyboard it is on the left sharing a key with @

You have to find backquote `````````
On my keyboard it is top left.

You've probably notice this already :-)
