ok, I think, I get it now. Thanks!

Do Red handles block data-type so far ?

Red/System does not have a block datatype.

Will it  ?

I'm pretty sure that Red will have a block datatype, not so sure 
about Red/System

I guess there will be a way to access Red blocks from Red/System. 
Until then, you can implement your own

I'm about to for cURL, to receive an unknown quantity of data into 
memory

Red/System will not have high-level datatypes, but will be able to 
use the low-level methods of Red's datatypes if required (mainly 
for supporting Red). Anyway, Red/System is not meant to use those 
"boxed" datatypes, only low-level and close to the CPU types.

Geomol, this is an example in C:

    #include <stdlib.h>
    #include <stdio.h>
    #include <dlfcn.h>

    int main(int argc, char **argv) {
        void *handle;
        double (*cosine)(double);
        char *error;

        handle = dlopen ("/lib/libm.so.6", RTLD_LAZY);
        if (!handle) {
            fputs (dlerror(), stderr);
            exit(1);
        }

        cosine = dlsym(handle, "cos");
        if ((error = dlerror()) != NULL)  {
            fputs(error, stderr);
            exit(1);
        }

        printf ("%f\n", (*cosine)(2.0));
        dlclose(handle);
    }

who generates the appropriate assembly code for the     (*cosine)(2.0) 
   call? The C compiler.

Yes, but we're talking doing that in a high-level interpreted language, 
like Python, Ruby, Rebol, etc.

In a situation, where you don't know the function at compile time.

R3 does not have such ability, so I'm confused by your "When looking 
at the host-kit for R3, I see functions to open, close and find functions 
in DLLs, but I don't see the calling of those functions."

Ok, I thought, R3 had that ability and used those open/close functions 
to do it.

The code is in R2, but out of reach.

R3 uses dlopen/dlsym/dlclose to load R3 extensions, which have a 
clearly defined exposed API (RX_Init, RX_Call).

Mac OS X now fully supported: http://www.red-lang.org/2011/07/mac-os-x-port-released.html

Nice, but the original "hello" demo was with red color:)

Well, if someone could bring color (using ANSI codes?) to the Mac 
and Linux version, that would be nice! :-)

Ok, I have added the red color to Mac and Linux platforms...updating 
the screenshots now ;-)

Looks much better now. :-)

I don't have Linux nor Mac at this moment... are you using just string 
like "^[[31mRED^[[0m" ?

Yes, have a look at the hello.reds source code: https://github.com/dockimbel/Red/blob/master/red-system/tests/hello.reds

You're too good for us :-)

I like colors... I'm looking forward to see colorized console one 
day:)

Implemented support for argc, argv and env for UNIX platforms, will 
publish it tomorrow when Windows support will be ready too.

Cool, thanks!

That enables another large class of programs

great! now it's getting more useful.

Command line arguments access now available: http://groups.google.com/group/red-lang/browse_thread/thread/4b8cb7a5a49308ba?hl=en

Tested ok on all OS (including Syllable).

Great, I was just looking over it, and couldn't see anything wrong 
yet

In my first release, I wrongly read ESP data instead of [ESP] for 
Syllable.

Ah, the detail devil :-)

I once offered a little glowing "code protecting" angel statue to 
one of my developers. It was supposed to keep devil out of your code 
if you kept it close to your screen. Can't find it online anymore, 
maybe that would help...:-)

New Red/System document is available: BNF language grammar description 
(by Rudolf W. Meijer)
http://static.red-lang.org/A_BNF_grammar_of_Red_System.pdf

Very cool Doc (and Rudolf).

I've cleaned up my cURL binding enough to put it in a repository:

http://red.esperconsultancy.nl/Red-cURL

very nice work!

Thanks

cURL link added to Contributions section: http://www.red-lang.org/p/contributions.html

I'm temporarily bored with all the cURL bindings, so I've started 
working on an SDL binding

good choice:)

that's nice!

I thought you would like it, Oldes :-)

We'll see how far we can get with sound and graphics without floats

I can open and close a window now. Imagine VIEW [ ] :-)

I can have a window without any borders, so you could make your own 
window manager
