That's pretty cool!
Would it be possible for me to get a copy of your REBOL script?

REBOL's blocks and hashes are powerful, but there's still no easy way as far

Here's the way I summarize it:
It all comes down to communications. The object-oriented approaches (CORBA, etc.) are
trying to do it with their arms tied behind their backs.
Good communications requires language, not just static language, but living, mutating

That's a great question! We should put it in our FAQ (ping: Bo). There are two answers:

ROUNDING FUNCTION
regarding Ralph's comments I agree
it would be nice to see a rounding
function native to rebol and also
a /refinement to specify to number
of decimal places you would like
a number rounded to.
sounds like an appropriate suggestion
for FEEDBACK Ralph ?
cheers,
Mark Dickson
I would have expected [3 2 1]
not [1 1 1] nor [3 3 3].
But I find it difficult to answer what I want, because the function argument
x seems like it's in a bit of a no-mans land (I'm thinking of :x )
My brain hurts now. :)

yes... rounding.r is nice... anyway, my routine works well enough for the
purpose I required... but it would be nice to see a rounding function
included in REBOL.

his outliner XML idea is rather powerfull :-)

This is probably not true; each context is independent from the
others.

The nice thing about foreach is that you can also parse your block
into more than than one word (variable):
farm: [[pigs] [chickens]]
foreach [pig chicken] farm [print [pig chicken]]

Also the webcam doesn't seem to update

Because REBOL does not have something like a "scope". Notice that
there are no variables at all, only values.
Some of these values, called "words", have the ability to refer to
other values.
Hello [EMAIL PROTECTED],
Well, scope in REBOL is a quite different beast than in most other languages.
In REBOL you don't only have two scopes (contexts) - you have a tree of contexts, each
one with a parent context, the top level context being what you could call global
variables.
REBOL does
