Thanks.
It looks like you're still using an arbitrary wait time to assume the
logging event queue is empty. I like it much better than my sleep idea, but
it seems like there is still the problem of choosing between 1) using a
timeout value to short and missing a log message, or 2) using a time

Hi David,
Thanks for your swift response ,I simply do not know how to run this

Maybe the language is not pretty big ?

Interesting problem; your screenshot shows header text that should not appear
in the window, which suggests to me that you copied and pasted the text from
somewhere else into a buffer where the language level was already set. It looks
to me like you should do the following:
1) Delete the first
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 metadat
It seems the metadata lines added by DrRacket (mentioned by John) are
processed when the a source file is loaded into DrRacket (via the menu
option File/Open), but are not processed if the source code is directly
copied (e.g. from a browser window) into a DrRacket window and then
executed with the

OK, I found a much better way. Rather than trying to tweak a syntax object
to pass in to "examples", it's much easier to use the Low-Level Scribble
API to rebuild a document fragment that looks like what the built-in
"examples" would build. What I have now just needs a little CSS and it
looks c
