Dear Robby,

The more I get to know Racket the more impressive it is. On the one hand
everything is so high-level, well thought out, simple and straight forward .
Unlike Python I don't even have to install an extension to do Wind

Dear list members,
Is there an extension or package for Racket that can call the Win32 API ? I
don't need the whole API. I only need to execute a Win32 shell command to
open a file with its default application indicated by the files extension.

I had to skip v5.1.2 due to some incomprehensible error. Other than
this and plot module providing a new proc 'inverse' which caused minor

This problem was caused by a bug in the bytecode compiler. The bug was
exposed by usual code (including a `set!' to an other unused procedure
`let' binding) in the "Debug" button's transformation of the expanded
`match' form.
I've pushed a repair to the git repo.

Expanding on what Robby said about the statistical profiler (the
`profile' module) being more useful: I've found that the statistical
profiler more often correctly reports the names and source locations of
functions. It also doesn't require compiling your code with profiling
enabled - it just w

If I recall correctly, long lines in the definitions window of DrRacket were
automatically split such as to be visible in even a small window. Nowadays I
see a scrollbar appear and lines are not shown split up. This is in

Turning on profiling is an action in the Language dialog. It needs to
be set up before your program is compiled (which the below doesn't
do).

Thanks -- although when I tried this a dialog popped up saying "There is no
profiling information available. Please be sure that profiling is enabled..."
So, I added two lines of code above the def'n of even?:
(require errortrace)
(profiling-enabled #t)
Same dialog pops up even so.

It looks like main.the_procedure is returning either defined composite

As a workaround, you can extract the components of the ROW value so
