Once you have plugins and commands, there may be less need for rebcode! 
- you can just write natives if need be. The reason for a rebcode 
replacement then would be security (not rebcode's strong suit), since 
rebcode would be managed code.

security (not *the old* rebcode's strong suit)

OK, thanks for explanation. Looking forward to something more concrete 
= 1st plugin code example :-)

brian: what is Carl using for compilation... GCC?

He doesn't say, but I expect GCC on *nix and OSX, and I'd be surprised 
if he wasn't using MSVC on Windows. REBOL has been around much longer 
than GCC has been usable to build normal Windows apps. We'll seee 
soon :)

what do you call words such as "back" and "tail" and "next"?  Is 
there a special term were using for these?

I call them navigation functions, usually for series. I'm not aware 
of any official term.

I'm thinking about putting in an enhancement request.

or wish.

Interesting. For what do you wish? :)

if so, there should be a way to classify them in a helpful way in 
documentation and help

These functions have been part of the recent debate over series! 
and its types...

the nearest method is to search for functions that manipulate specific 
datatypes.

http://curecode.org/rebol3/ticket.rsp?id=844

I just submitted that wish.

there is a better way to write that request: AT should support block 
directly as index.

what you mean?

copy/part does that.

yeah but that is a copy.

BACK TAIL series sets the position - the AT is a noop in your example.

not sure what that means.

BrianH, not if the AT specifies a different series than the BACK 
TAIL.

if it isn't doable just update the ticket to state such.  I just 
wanted to get the wish in there in case I think of it again and forget 
we discussed it.

instead of writing:

at block1 index? block2

it could be:

at block1 block2

But those are supposing you know the index length.   I was hoping 
to avoid that with my request.

Specifically for dynamically allocated series.

you can always use skip -n if you want to jump relatively in a series.

to me it just seemed more REBOLish to use AT in the manner that I 
posted.

Follows the KISS principle to me.

I can update the ticket if you like. What would you like it to say?

INDEX? can return the result of your calculated position. Your example 
would be:
AT series1 INDEX? BACK TAIL series2

Wait a minute - Carl's method is simple things should be simple to 
do (STSBSTD).  A longer acronym.

You can write what you want.  It is just a placeholder for me to 
not suggest it again.

I'm not downplaying it, I'm just trying to clarify. At this point 
I don't understand what you want well enough to answer the question.

I don't understand it either... what should be result of your example 
code?

i think he wants AT working like COPY/PART (the index could be an 
integer or a serie aswell)

Well, if the index is a series offset, even a calculated one, then 
you can already have a reference to that offset without the AT.

It makes sense if the 2 series are differents.

but i agree, i don't see so much use cases for that.

>> series
== [1 2 3 4 5 6 7 8 9 10]
>> series: at series back tail series
>> series: [10]

>> series
== [1 2 3 4 5 6 7 8 9 10]
>> series: back tail series
== [10]
The AT is implied by TAIL, and then again by BACK.

yeah only example I can think of.

I had it written down from something I had been working on.  Go ahead 
and resolve the ticket if you like - if I come across the problem 
that resulted in my notes then we can revisit it.

An example where you are trying to go to the same position of another 
series would be more useful, since that would mean removing an INDEX? 
function instead of adding an AT function.

Yeah in my notes I have "no copy'" so something I was involved with 
wanted the fucntionality without copy.

Interesting. No copying is going on here, just references passed 
around.

Ahhh, just AT series back tail series.

so in other words the following:

at series back tail series

The assingment is implied.

no need to set series: at series back tail series.  But instead the 
at command is manipulating the series directly for the navigation 
arguments.

Wait... Are you Paul ? really ?

Yes Steeve.
