What happens if you make the first line of the file be #lang racket,

Well actual program is here :

Running example1.rkt produces the error in DrRacket , but runs fine in
console.
Thanks.

Hello -
I have found code for a Scheme version of the Porter stemming algorithm.
Supposedly it has been tested on PLT Scheme but when loaded into
DrRacket there are many unreadable characters and syntax errors.
Is there an implemention

web-server/templates uses scribble/text

Awesome. Ok, I've taken the code there and put it up as a Racket
PLaneT package to make it easier to use.
For example:
If you're looking at the suggested solution, the easiest way to get the
code is to follow the links to the codepad page and copy the code from
there.
If you're looking at the program in the comments, you may want to view
source and scroll down to the program. You'll have to delete the html tags

I was afraid, you'd say that.
If this is for resizing, you have another problem: creating a new plot

Many thanks for your interest. I have used the version just uploaded to

and it works. For a Racket ignoramus like me this is a buzz! Many thanks

Do you mean by creating a new readtable?
