Does one can explain :

>> b: next next [1 2 3]
== [3]
>> head b
== [1 2 3]
>> head copy b
== [3]
>> c: [9]
== [9]
>> insert/only c b
== [9]
>> c
== [[3] 9]
>> d: copy/deep c
== [[3] 9]
>> head d/1
== [1 2 3]

head copy b

 show that 'copy only copy the block at the position we point into.

So why does 'copy/deep don't ?

about graphics in core: would that mean you could create graphics 
without requiring an X server if used on BSD/Linux? I believe that 
X is normally necessary...

Dide, Good question for Carl.

Henrik: yes. Command has grafx capabilities without VID and without 
requiring X. So you can typically save/png etc.

x ins necessary for fonts-handling. rest would work without it. except 
that /view does some initialisations at startup and fails without 
view.

(means without X)

Regarding the question on the mailing list on extracting a series 
of duplicates, I wonder why Rebol doesn't allow us to subtract one 
series from another.  If we are allowed to append one series to another, 
why not allow us to subtract?
But I guess the problem then is sameness.

we have that with set-operations. only it does not keep duplicates 
(i prefer it this way). And the duplicate-thing can be solved in 
a little loop, as gabriele showed.

As Volker says, exclude acts as a sort of subtract, but does not 
handle duplicates in the way the questioner needs.
>> exclude [1 2 3 4 5] [ 3 5]
== [1 2 4]

Are any technical details on encloak and decloak functions ?

I think this is as technical as it gets
http://www.rebol.net/cookbook/recipes/0023.html
Which tells you it is SHA1

thanks. The key is SHA1 encoded makes me guess that it's hard to 
break the key but not the "encrypted" content

Is there anyway to get the ip address of the local computer?  My 
problem is that I use a VPN for some functions and have other techs 
that do also and wanted to make a utility that could simply determine 
what subnet they are on.  Problem is that I get the local ip of the 
lan and not the other interface ip's.  Anyway to get those?

This is one of my more major problems with REBOL - it is an internet 
language as advertised so you assume tasks like this would be simple 
or for example enumerating connected or listening ports, retrieving 
a routing table etc.  At least I can use call to get some other application 
to do it for me.

Does this do it?
 read join dns:// read dns://

that returns local loopback on my fedora core installation

When I did the above, I was using a dhcp supplied address.  When 
I change to a static ip, I get the same result.

Sunanada - that only returned the lan interface ip but not the vpn 
interface ip that I wanted to get

I can get the ip information from the system/network/host-address

But its not the right stuff I need

Paul - non ability to open port on specific device or stuff you mentioned 
should be submitted to RAMBO as a wish, or as a bug, if Rebol claims 
to be networking internet language ;-)

Paul maybe this will help you.

use [port interfaces][
    ipconfig: does [

        until [attempt [port: open join udp://: 64000 + random 100]]
        interfaces: get-modes port 'interfaces
        close port
        foreach dev interfaces [
            print reform compose [
                join dev/name ":" "flags" mold dev/flags newline
                "^-inet" dev/addr "mask" dev/netmask 

                (either dev/broadcast [["broadcast" dev/broadcast]][""])

                (either dev/dest-addr [["dest-addr" dev/dest-addr]][""])
            ]
        ]
        interfaces
    ]
]

Wow - Jaime that worked!  Excellent

can ports be gathered from the interfaces also?

such as what ports are connected - listening etc..

No. You will need something in the os.

ahh ok

They should add that and we should have a command like the one you 
gave as a mezz function

You could always use CALL to get this info and the parse it.

What OS?

yeah I know I actually have to do that now with a call to netstat 
-aon

You could always use CALL to get the open ports on the host system 
and the parse it. What OS? Do you want support for?

I'm working on a project now that I want to send out but don't want 
it to look so much like a batch file as much as having its own capabilities 
inherent.

Lower level access in rebol is only possible either through CALL 
or via a SYSTEM CALLS using the DLL access.

Yeah the DLL wont cut it as this would require the use of my /sdk 
license and the company wont go with that.

The CALL function really helps now though

I really hope RT puts some functions in to free REBOL distros such 
as remote registry capabilities

Then we can use it for administrative purposes and role it out to 
40,000 plus desktops

Why not just use SDK. Surely a BigCo can afford it. Besides I think 
is better to distribute such tool in an encaped form.

You don't want someone changing the src code of a script that manipulates 
the registry of a host environment.  Too much security risk, 80% 
of security problems oringinate inside the companies infrastructure.

Its strange but they wont purchase things that are not accepted by 
the application development teams to support other clients.  The 
only way to really penetrate the big companies in this regard is 
to have one heck of a salesman that can talk about standards and 
support or bring it in free where there is no costs or penalties.

Well with XP pro which is our common operating environment scripts 
can be set to run under certain credentials

We currently have WSH carry much of that load

Really strange... What about "A build it and they will come strategy"?

That's just not realistic enough

We have perl used extensively as well
