[racket] Problem around Creating Excutables

Oh, Thanx. I see, now it works!

------

#lang racket

(current-output-port
 (reencode-output-port (current-output-port) "shift_jis"))

(display "あ")
(flush-output)

------

Yeah, for Japanese people using Windows, the word "SHIFT-JIS' is so
familiar; but strangely, it didn't pop up in my mind.... (I tried putting
'windows-932', since chcp command told me so, several times, and I was
being upset) (^^ ;

Now having "mojibake" solved.

Here are two questions.

I'm trying making a game with REPL structure, or similar to an interpreter.
I guessed, according to the code above and the discussion shown in:

https://groups.google.com/forum/#!topic/racket-users/MGDUNnUVzWU

, I have to put '(flush-output)' here in like this:

------

(define (read ....))

(define (eval ...
    ....
    ;;; pseudo
    (cond ((you want exit?)
              (flush-output) (exit))
             (else (continue-game))

    ...)

(define (print ...))


------

Is this O.K? or do I have to put (flush-output) every time after (display)?

The second question is... The game I compiled is, after shown several
processes I made, got Abend, though running on Racket Interpreter is fine.
What is the reason of this? Do I have to put something like
(current-input-port)
 stuff?

Thanx
