Ah! you just answered that  ;-)

yes. try:

make object! []

and context []

and see what's returned

or more revealing:

>> source context

context: func [

    "Defines a unique (underived) object." 

    blk [block!] "Object variables and values."

][

    make object! blk

]

it's all just a big re-dress of objects. :-)

Think I get it - It's the object oriented side of Rebol - you could 
say that bind is a sort of inheritance ?

more like membership. there is no real inheritance in Rebol.

Yes, MS always partly implemented OO in VS. they didn't think there 
users could handle them !  Java is more of a full OO implementation 
but I find you end up having to override most objects and that's 
not good for code re-use.

OO is ok but it doesn't always fit the real world (or programming 
productivity). that's why I think OO Databases have never really 
been adopted! they fit models but not the real world (Where the customer 
say's Ahh! didn't we mention that !! (LOL).

This should be instructive. Type this into the console a line at 
a time:

o1: context [my-word: "hello"]
o2: context [my-word: "there"]
o3: make object! [my-word: "SteveT"]

code: []
append code in o1 'my-word
append code in o2 'my-word
append code bind [my-word] o3

print code

I first show two different ways of creating an object, and then I 
show two different ways of getting a word in an object.

I got a halt-view near my-word?

Show me the code and resulting error.

Maybe you missed one of the single-quotes before a 'my-word (which 
makes it a lit-word!)

eg.  in o1 'my-word   ; <-- don't miss the '

o1: context [mu-word: "hello"]
>> o2: context [my-word: "there"]
>> o3: make object! [my-word: "SteveT"]
>> code: []
== []
>> append code in o1 'my-word
== [none]
>> append code in o2 'my-word
== [none my-word]
>> append code bind [my-word] o3
== [none my-word my-word]
>> print code
none there SteveT

Yep think so that 's what i got now

first line says "mu-word" :)

Dohhh! it's this eclectic keyboard lol

'my-word is therefore not in o1 and so:    in o1 'my-word  == none

:)

first o1
first o2

Lists the words in each object, if you don't believe what IN is telling 
you.

Or of course you can use HELP or ?.

? o1
? o2

Think I understand that

Each word carries its binding with it. ie. a reference to an object. 
(or no object if it is unbound).

Can you get problems if an  object gets bound to itself?

An object is a container of word -> value pairs. When you ask for 
a word's value, the word's binding is checked to get the object.

An object cannot be bound to anything. Only words can be bound.

Sorry that's what I meant 'Word'

A word isn't really a binding target, so you can't bind a word to 
itself (or any other word.)

(BIND accepts a known-word argument. It is the *object* that the 
known-word is from, not the known-word itself, which is the target 
for the bind.)

Right - the context it's from ????

Correct. (context = object).
So my above example could be modified to:

	append code bind [my-word] in o3 'self


which is in fact how we used to have to do it, because BIND didn't 
have object! in list of accepted types for its known-word argument.

so these are all the same:
	append code bind [my-word] o3
	append code bind [my-word] in o3 'self
	append code bind [my-word] in o3 'my-word


(we would use the 'self word because it's in every object by default.)

The order of execution throws me more than anytihing I would have 
had to do your code like this

code append bind(my-word etc)

I'm so used to starting with the item

Are you an ex-forther or something ?

(sorry, don't mean to sound rude...)

No VB, C'#  You tent to start with the object and then using . notation 
you tell it what action to take on it.

Ah of course. Much better this way :)

Rebol you say what you want to do then which object you want to do 
it to lol

As I said on my blog I'm just entering my second week of de-programming 
;-/

.. rebol is like:   VSO = Verb Subject Object
VB, C# is like:   SVO = Subject Verb Object
and Yoda is :  OSV

Yeah your mind get comfortable one way or the other - takes a lot 
of breaking

So actually rebol is less like english in that respect. But actually 
english is crazy. It's better to have the verbs at the front.

Actually rebol has objects and path notation, so you SVO too.
eg.   ctx-text/unlight-text

Yes that's where English is wierd for people to learn English say

Bus Station

Spanish say Station de Autobus 

perhaps i should Rebol in spanish ;-)
