[racket-dev] More completed examples to show how to use lexer in Racket

Hi,
I am playing around the Racket recently, implementing a lexer for a toy
language.

I understand the calculator example in the parser-tool, but it is too
simple, are there more sophisticated examples that show how to use all
features of in the Racket lexer mentioned in the doc?

In the read.rkt example, I am especially confused how the start-pos and
end-pos are used....

Thanks for any suggestions.....

Jenny
