Hello Or,
The language is not "Pretty Big".
You should be using "Beginning Student with List Abbreviations".
The DrRacket metadata lines referred to by John set the correct language.
In your case you must have changed the language somehow. Or perhaps the
file needs to be saved before the
ink, a bug and a trap (perhaps showstopping) for
a new user experimenting with Racket.
Note that the Racket executable seems to process the metadata properly,
understanding the language to use, etc.. so that the code behaves as
intended.

Hi all,
I'm trying to debug my (Windows7, 2-button trackpad) system, specifically,
weird behaviour with the mouse.
To help determine what the actual problem is, I wrote a small Racket GUI
progam, that surprised me with the following output:
object:object:my-frame% type:enter pos:(338,32)
If I understand correctly, the difference to getting the code to type
check was:
> (apply fprintf (cons anomaly (cons message messageargs)))
becomes:
>(apply fprintf anomaly message messageargs)
Since the documentation explains that the arguments to fprintf are
effectively
s as written.
