[racket] specifying strings without escaping backslash

Thanks everyone,

The @ syntax does what I want.
After I asked the question I found the answer on the Racket list.
The below based on this
http://www.mail-archive.com/users@racket-lang.org/msg07162.html
-------------------------------------------------------
#lang at-exp racket
(define RAW string-append)
(display @RAW{C:\Users\Harry\SANSKRIT\GRETIL ALL\adyappu.htm})
----------------------------------------------------------

What am I doing wrong here.  -- everything :-)
I'm trying to change the command character from @ to #  so that I can have
raw strings containing both \ and @
looking at the racket documentation here:
http://docs.racket-lang.org/scribble/reader-internals.html?q=at-exp#%28def._%28%28lib._scribble%2Freader..rkt%29._make-at-readtable%29%29

I've done this:

#lang at-exp racket
(require scribble/reader)
(use-at-readtable #:command-char #\#)
(define RAW string-append)
(display #RAW{C:\Users\Harry\SANSKRIT\GRETIL ALL\adyappu.htm})
(display #RAW{harryspier at hotmail.com})
