Had a false start a few months ago with my outdated Lisp-in-a-box on a mac but picked up a cheap as chips Thinkpad and thanks to a very helpul fellow on youTube got emacs,SBCL,Slime installed ok.
Working slowly through the above mentioned book and i'm already stuck on page 23
CL-USER> (defun prompt-read (prompt)
(format *query-io* "~a: " prompt)
; caught WARNING:
; undefined variable: *QUERY-IO
; compilation unit finished
; Undefined variable:
; caught 1 WARNING condition
STYLE-WARNING: redefining COMMON-LISP-USER::PROMPT-READ in DEFUN
What does this all mean? it does return PROMPT-READ after all ?
Thanks in advance
