Hello Ladislav,
Just read your new Interpretation essay, very good work, I love the way
you can skillfully describe low level REBOL behaviour with high level
descriptions and examples and for this you deserve credit.
Just one minor improvement I would like to suggest to your text.

Hi Mark,
You stated When the interpreter finishes evaluation of all values
contained in the block, the last obtained value becomes the result.
Almost true, but not quite. What if the last value in a block is unset!
I think, that it is true. See:
type? do [print 1]
1
== unset!

Hi Romano,
I don't think, I must change your mind, but there is a difference you
probably don't see. It is possible to define a Rebol function (a FUNCTION!
datatype value to be exact), that takes one argument and evaluates it:
do-f-0: func [f] [

]

Hi Ladislav,
I still think my original posting is correct as DO
does EXIT if the last value in a block is an UNSET values.
In your example UNSET! is a datatype! value NOT an
UNSET value.

type? type? do [print 1]

== datatype!

I would like to apply the same operation to all members of a nested block.

Ladislav,
sorry about the confusion, I your new essay you said that DO returns the last value in
a block! as the result.
But you can never get UNSET returned as the result of
an expression ie
== unset
sure you can get
== [unset]
or
== unset!
but these are block! and datatype! values.

Now i've understand. That function exists: it is 'do also if we can't write

Hi Tim,
I think map will do what you want.

return result

Dont use 'foreach. 'Foreach makes a copy of the value, bungling your method. Use
'forall or 'repeat. I like using 'repeat for this sort of thing because I can do it
without the awkward [block: head block] at the end.
Also you might want to use 'block? instead of 'series? to validate whether

Ok. I have this problem where I paste a large amount of text in an area box 500x500.
Then I send it thru an encryption process which changes the data and does a show on
the same area window. The problem is that I dont see the data unless I use the arrow
keys to move up and then it scrolls
Since this type of thing seems the like the fashionable function to write
these days, I thought that I had better offer my own version quick before I
get out of style...

Upto here, we agree. Functions have a fixed number of args. Right?
No, not AFAICT...
We are not speaking of any-type! args.

Hi Mark,
you didn't waste my time.

That is an error, IMO. There are expressions that yield the (Unset) value.
The only difference between this value and any other value is, that the
