Should the description read like this:

DESCRIPTION:
        Returns TRUE if the values are identical references.

or 
        Returns TRUE if the values are identical objects.

It returns true if the values in the value slots have exactly the 
same bits. For immediate values (chars, numbers, typesets, ...), 
that is exact equality. For reference values (strings, blocks, objects, 
bitsets, ...) that is exactly the same reference. So that means that 
SAME? 1 1 returns true even though those integers are in different 
value slots.

Since that is two different forms of equality, we had to use the 
more general term "identical". We can't test reference equality on 
immediate values because REBOL is a pass-by-value language, and only 
passes references when that is the value, as it is for reference 
types.

Thank you Brian!  That helps me understand it a little more.

In R3, reference types are the types that aren't in the immediate! 
typeset (which is just documentation):
>> print mold immediate!

make typeset! [none! logic! integer! decimal! percent! money! char! 
pair! tuple!

 time! date! datatype! typeset! word! set-word! get-word! lit-word! 
 refinement!
issue! event!]

That reminds me, I should check whether the immediate! typeset was 
added to R2/Forward and R2 yet.

In R2 it would not have all the same types, of course, but it should 
be a strict subset.

Hi,so i am quite new to the rebol community and have been assigned 
a project to work on.So to be frank i started reading rebol 2 days 
ago and i am quite confused since i worked with c++ before that.I 
am stuck at flow control and operators(sad i know).So basicaly i 
thought of when i moved from delphi to c++,basically if one of you 
guys can provide me with a rebol version of this small program i 
whipped up(flow control number check-the basics) it would be of great 
help to me,so here is my program and thanks in advance.
    

It inputs an integer number n and outputs the sum: 1+22+32+...+n2.I 
use input validation for n to be positive.
#include <iostream>
using namespace std;
    
int main()
{
     int n;
     cin >> n;
     if (n < 0) return 1;
     int sum = 0;
     int i = 0;
     while (i <= n) sum += i*i;
     cout << sum;
     return 0;
}

Welcome!
I've posted one possible approach on REBOLforum:

   http://www.rebolforum.com/index.cgi?f=printtopic&topicnumber=46

thanks i will have a look at it trough the interpreter this looks 
promissing and not that hard

:D

REBOL is a very human-oriented language... as little syntax as possible 
(notice how there aren't any parens for functions. for example)

yeah exactly

if you are very used to C++ this will feel awkard for a while  though 
 :-)   its almost like the total opposite.

well it did look like moon-speak :D

in a year, C++ will feel awkward :-)

well guys i have to say the community works and i am pleasntly impressed.I 
am checking the libraries now and trying to get the script to work 
since i am getting  ** Access Error: Cannot open /C/users/alemar/download/test.r
** Where: halt-view

** Near: do %/C/users/alemar/download/test.r                     
                                                                 
                   i will figure it out eventually and i can get 
to real programing in this langueage** Access Error: Cannot open 
/C/users/alemar/download/test.r
** Where: halt-view

** Near: do %/C/users/alemar/download/test.r** Access Error: Cannot 
open /C/users/alemar/download/test.r
** Where: halt-view
** Near: do %/C/users/alemar/download/test.r

don't forget to put a header to your file :
Rebol [ ]

We don't know whether the file exists, e.g., what does the expression

exists? %/C/users/alemar/download/test.r

we went over all that in the i'm new group.  :-)

Is there an easy way to suppress a carriage return and line feed 
when hitting the enter button?

For example:  I'd like to be able to do this:
Guess # 1:  XXX <enter> "  Nope, too high, guess lower"
Guess # 2: YYY <enter> "  Nope, too low, guess higher" ...

Can this be done with the ASK somehow?

http://www.rebol.net/cookbook/recipes/0060.html

Henrik,  That is close, but I'm looking to be able to enter several 
characters, then hit the enter button, but NOT have a LF character 
printed at the time of the enter.

perhaps check the source for the INPUT function

(which is used by ASK)

Will do!!!

A while ago someone made a text UI dialect for R2 that used ansi 
codes to move around. You might consider looking into that. It is 
likely in the rebol.org script library.

I'm stinking close!!!! But not there yet:  Try this in R2:

		set-modes system/ports/input [binary: true]
		string: []
		until [
			prin char: to-char input
			append string char
			char = 13 ; <enter>
			]
		set-modes system/ports/input [binary: false]
		head string
		print "string: " string

After each typed character, I do get the console to print each one 
out, but then I seem to loose the end value when I hit enter

Is there an equivilent for SET-MODES system/ports/input [binary: 
true] in R3?

No, not yet.

Any ideas on how to get my end value in R2?

No SET-MODES at all yet.

Any idea on what I'm doing wrong with R2 for this code:

		set-modes system/ports/input [binary: true]
		string: ""
		until [
			char: input
;			print char-x: to-char char
			if not char = 13 [
				prin "-" prin char-x: to-char char
				append string char-x
				]
			char = 13 ; <enter>
			]
		set-modes system/ports/input [binary: false]
		head string
		print "string: " string

Typing in the following gives me this:
-1-2-3string:      

I was hoping for
-1-2-3string: "123"

Typing in      123<enter>

dinner calls -- will check back later

Might be that last print statement.......I think you mean:
    	print ["string: " string]

or perhaps:
    	print ["string: " mold string]

Dohhhhh! That is right!!  Thank you Sunanda

I am plaqued by a simple problem.  In R2-core, I keep on getting 
a Security Check prompt when attempting to read a file.

I am able to avoid security check prompts with R3-core by setting 
SECURE [DEBUG ALLOW] in %rebol.r
But I am not able to do this with R2-core. 


What is the proper way to use the SECURE [FILE ALLOW] option so that 
I am not continually prompted all the time?
I've tried it in my rebol.r file but it still asks me for this.

Another annoyance -- I am not sure why, but R2-core seems to require 
two REBOL [] headers for %rebol.r and %user.r -- Is anyone else seeing 
this as well?

Is it possible to get the value of variable number of occurences 
while parsing block?

Foe example, I have the following 

block1: [cancel "res-1" "res-2" "res-3"]	; the number of strings 
following 'cancel might be 1, 2, 3...

>> parse block1 ['cancel set res-numbers some string!]
== true
>> res-numbers
== "res-1"

Is there a way I can get all three strings? Thank you very much!

>> parse block1 ['cancel copy res-numbers [some string!]]
== true
>> res-numbers
== ["res-1" "res-2" "res-3"]

>> parse block1 ['cancel copy res-numbers some string!] res-numbers
== ["res-1" "res-2" "res-3"]
>> parse block1 ['cancel return res-numbers some string!]
== ["res-1" "res-2" "res-3"]
These are all R3 though.
