I can think of one possible better way, assuming the multiple values
in an actual program are generated by some other function. Obviously
with (loop (values (add1 a) b)) you can simply write (loop (add1 a)
b). But if you had (loop (f a b)), where f returns two values, you
can write the following:
I'd like to be able to write something like this:
(let loop ([a 1] [b 2])
(if (= a b)
3
(loop (values (add1 a) b
This would match the way for/fold works with more than one value.
However, I get a message, "context expected 1 value, received 2
values: 2 2", which makes sense giv

Thanks for the information, Vincent.

Have you tried the nightly builds?
http://pre.racket-lang.org/installers/
Some Lion-related bugs have been fixed since the last release. The
fixes will be in the next stable version, which should come out in a
week or two.

Hi,
I am using the mac OS lion, and tried to install Racket from binary(Mac OS x
intel 386), but it does not work on my machine (it will exit drracket
immediately when you tried to run it)
then I download the source, trying to compile it. But the errors came up as

Thanks,

That service pack was released seven years ago; and indeed, Microsoft
considers XP SP2 itself at end-of-life, unsupported for the last year.

Yes.
Is some security feature enabled that might inject uses of
DecodePointer() into the code?
There's nothing that I did explicitly. Also all the solution files
are just converted from the older version and tidied up

That looks right, though pretty verbose... (And BTW, you're missing
some way to mark the code as such -- there's no indentation!)

Yes, the talks were recorded, thanks to Jeff Dlouhy of the

Hi,
I remember somone mentioning recording racketcon might happen.
Will the presenters presentations(slideshow? ppt?) be available.
Forgive me for asking too soon after the event.
Kind regards,

DecodePointer() is in XP SP2 and up, which explain why it works on my
XP SP2 machine.
When I compile my own binary with VS 2008, there's no use of
DecodePointer(), though. There's no direct use of DecodePointer() in
Racket.

Hi Doug,
thanks for the kind offer! In fact I've not been able yet to find out how to
have a non-numeric x-axis using plot/extend ... I don't seem to find a related
function...
Now as it's not terribly important - I can use a "workaround" converting the
non-numerical data to numbers, only then
I just discovered something. I installed v 5.1.2.3 on my Win XP machine. When I
try to start DrRacket, I obtain
"DrRacket.Exe - Entry Point Not Found: The procedure entry point DecodePointer
could not be located in the dyynamic link library KERNEL32.dll."
So maybe Win XP with any SP should jus
