Space character inside an argument (emacs lisp) -

-

in windows, set variable inferior-lisp-program (shell-quote-argument "d:/program files/ccl/wx86cl.exe").

but when run inferior lisp command run-lisp, emacs responds:

searching program: no such file or directory, "d:/program

it seemed emacs treats "d:/program files/ccl/wx86cl.exe" 2 arguments "d:/program , files/ccl/wx86cl.exe" separated space character.

how can make emacs treat "d:/program files/ccl/wx86cl.exe" whole?

try using old "progra~1" compatibility name "program files". so, 

(setq inferior-lisp-program "d:/progra~1/ccl/wx86cl.exe")
