Thank you all for the suggestions, it was indeed the .txt extension. Now I
was able to run the program, however the results were not separated, they
were all in just one line. But I'm not going to worry about that.
Also thank you for suggesting the other resources, but so far I like the

This is just a guess, but perhaps Windows has helpfully added a ".txt"
extension (or some other nonsense) to the end of your filename? You
might try looking at the file's properties, just to make sure
something weird isn't going on.
On another note, as long as your Fahrenheit->Celsius function wor
You need to install a quit handler via `application-quit-handler'.
The quit handler is invoked by the "Quit" menu item.

right now, having
(yield (make-semaphore))
at the end of my program, the application doesn't exit and my root menu-bar
stays... but the quit menu doesn't work anymore... should I override it,
but with what, or am I missing something?
thanks!

H racket peoples!
I looked around the docs for racket/gui and I can't find how to do
something very basic... how can I leave a racket/gui app opened after all
windows have closed so that the root menu-bar can stay visible?
thanks!

Hello,
I'm using DrRacket as an accompanying material for the HtDP book. I'm
learning it by myself, not as a part of a schooll assignment.
I have a problem with the exercise 2.2.1 - when I run the convert-file
program it doesn't want to accept the input file, the error message I get
is:

the "make" prefixes).

Your version that breaks mainly breaks because you are mutating the record
and recomputing the formlet, rather than saving the formlet in the
continuation for both the display and the processing.
As far as what you'd like to write, I think that's a good start, but
there's a few problems.

this can't be fixed inside the PLAI language itself, because there's no
