[racket] eval working in REPL but not in source file

eval working fine in REPL but gives "ask: unbound identifier;
 also, no #%app syntax transformer is bound in: ask" error when used in
source file like

(require racket/include)
(include "world.rkt")

(eval '(ask abdur 'go 'north))

I have seen various questions regarding the same eval issue on racket
mailing list and in the documentation
but I didn't came across a case where they touch on case like this
where I am including another file and the function is defined in that class.

Any help would be greatly appreciated,
Thanks
