[plt-scheme] How to use (load path) in plt-scheme?

This is a weird script. Why not

> #!/usr/bin/scheme
> #!scheme
> (require scheme/system)
> (define bar "hello world")
> (display bar)

and be done?

I used to have the following:

bar.scm; dynamically generated via scripts and by-hand:
(define bar "hello")

foo.scm
(load "bar.scm")
(display (string-append bar " world"))

and I ran this for years.

For PLT v4.0, I changed it to

bar.scm; dynamically generated via scripts and by-hand:
#lang scheme/base
(provide bar)
(define bar "hello")

foo.scm
(require (file "bar.scm"))
(display (string-append bar " world"))

Works like a charm. --  Matthias
