</span>The best starting point I found for implementing languages in Racket is this<br>
article by Matthew Flatt:<br>

You can download all the examples and play with them. I suggest you<br>
take his version based on s-expr and modify it in small steps toward<br>
your own language. It's always easier to modify working code than to<br>
start from scratch.<br>
