Thanks for the tip Eli, that seems like what I'm looking for. I can't actually figure out how to use it for files though; when I write -------------------- (make-evaluator 'racket (string->path "aplusb.scm")) -------------------- I get the error message -------------------- open-input-file: `read' access denied for aplusb.scm" -------------------- even though I definitely have read access to this file. If I try -------------------- (define aplusb (open-input-file "aplusb.scm")) (make-evaluator 'racket aplusb) -------------------- then the error message is -------------------- exception raised by error display handler: directory-exists?: `exists' access denied for /; original exception raised: module: illegal use (not at top-level) -------------------- It works fine when I give the second argument as a string or an s-expression but that wouldn't work well for the intended application.
Have I misunderstood the documentation?

I am using Racket v5.0.1 on Ubuntu 9.10 (i386). >
