[racket] two question about DrRacket

Hi all,

1  I wrote

(define (p x)
  (+ x 10)
  (* x 10)
  )

The result of (p 4) is 40.  How can I display 14 and 40?

2  How can I compare two letters in Ascii order?  For example, when input
are "x" and "y", the program will tell x is before y.

Thanks a lot
