> clisp myScoreGenerator.cm someFileName
man clisp. e.g., with file
--- foo.lisp ------------------------------
(format t "*** args: ~{~s ~}" *args*)
-------------------------------------------
call
% clisp foo.lisp 1 2 3 "foobar"
*** args: "1" "2" "3" "foobar"
similarly, just pass in your file name and make your generator
output to it.
