Space character inside an argument (emacs lisp)

Question

In windows, I set the variable inferior-lisp-program to be (shell-quote-argument "D:/Program Files/ccl/wx86cl.exe").

But when I run inferior lisp with the command run-lisp, emacs responds:

Searching for program: no such file or directory, "D:/Program

It seemed that emacs treats "D:/Program Files/ccl/wx86cl.exe" as two arguments "D:/Program and Files/ccl/wx86cl.exe" separated by a space character.

How can I make emacs treat "D:/Program Files/ccl/wx86cl.exe" as a whole?

Answer 1

Try using the old "Progra~1" compatibility name for "Program Files". So,

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