Please read the manual before asking this kind of question. Both your question about the command line, and the other about compiling files, are answered in the User's Manual.

The advice to use command-line-arguments is not useful here, because that will only contain unknown arguments. Since --load is a known argument, it won't appear in that list.

In any case it's not clear why you want to look at the command-line args in the first place. The --load argument is used to load a file of Scheme code; it has nothing to do with compilation.

Thank you very much, but I unsuccessfully tried the following:


(define inputfile 0)

(set! inputfile (open-input-file (car (command-line-arguments))))


What is the correct usage of command-line-arguments?

Thanks in advance
