I think I understand what happened here: you have used an earlier version
of DrRacket where the teachpacks had slightly different names than they do
now and the old preferences confused DrRacket to the point that you have to
remove the old teachpack before it will run programs.
I have changed DrRa

This may or may not work - but it is worth a shot.
In the menu "Language" menu choose the menu item that
removes all the teach packs. Now click the run butto

Language -> Clear All Teachpacks
Language -> Add Teachpack
see two columns
choose image from 2e column only
That's it.
Thanks for the report; the error message should definitely be more informative

Cool. You can p
Thank you Danny. I used to program in Visual Basic and then Java with
related stuff, such as HTML, Javascripts. I learned C and Pascal in
school. Racket is quite different. It seems I need to use recursion much
more.

It sounds like you're beginning to learn Racket, which is cool. You
may find the the Quick Start documentation at:
http://docs.racket-lang.org/quick/index.
Thank you Stephen. The code does not work in general. I know how to do it
now.

"helper" is defined as "(lambda (ls) ...)"
The only place you call "helper", you give it "(vector->list v)";
Hi All,
I know now that
helper v
passes v into 2nd lambda.

Hi Jos and ALL,
The code is from website
http://stackoverflow.com/questions/4175626/scheme-recursion-error
I modified it. It is not about homework. I am learning and evaluating
Racket.
I use Language: racket; memory limit: 128 MB in DrRacket.
The error I get is
> (test 'a '(b a c a))
. . pr
Whast you describe seems correct.
How about showing me yoyur code after deleting vector->list?
If this is HOMEWORK, send it OFF LIST.
What language did you use?
