I'm not familiar with define-macro, I only use define-syntax, that's
the reason why I missed the point.

I don't want something more complex, your macro does exactly what I want.

I my main file, I defined a a-list of path with (build-path
(current-directory) dir) and I wrote a function get-path who merely
apply assoc on that a-list, so from any file loaded or required by the
main file, I can use my (get-path dir) to get the full path to a
specified dir.

Thanks a lot,
