World: r3wp

I'd've written it the same way too -- though on the test dataset, 
the find could be a equality test:
    if row/2 = map/1 [change row/4 map/2]

I think he's hoping for a more set-related way rather than procedural 
method.

I've posted a script that eliminates the inner foreach loop by building 
a hash! to use as a lookup. Should be a bit quicker but isn't really 
any more Rebolish.

No he don't need any other solution.  He just needs to use ports 
to do the work for him and preserve memory.

However, if another db type solution is desired here - TRETBASE would 
be suitable to this task nicely.

The great thing about using ports in this case is that you can access 
the data as it is changed.  So you don't have to wait until the whole 
script is finished executing.

I posted a reply there, but don't hang out there, so let me know 
if I need to respond to answer a question about what I posted.

Here's basically what I posted:

transform: func [
	block [block!] "Datatset to transform"
	cmds  [block!] "Transformation commands to perform"
	/local
		run-map-transform
		main= map-blk= src= dest=
		      =map-blk =src =dest
][

 run-map-transform: func [src [integer!] dest [integer!] map [any-block!] 
 /local val] [
		foreach item block [
			if val: select/skip map item/:src 2 [change item/:dest val]
			;print [val mold item]
		]
	]
	map-blk=: ['using set =map-blk word!] 
	src=: ['field set =src integer!]
	dest=: ['into opt 'field set =dest integer!]
	map-cmd=: [
		['map src= map-blk= dest= | map-blk= 'map src= dest=]
		;(print [=map-blk =src =dest])
		(run-map-transform =src =dest get =map-blk)
	]
	main=: [some map-cmd=]

 either parse cmds main= [dataset] [none] ; decide how to handle bad 
 cmd scenario
]


transform copy dataset [map field 2  using glcodehash into field 
4]

transform copy dataset [using glcodehash  map field 2 into field 
4]

Hacked quickly, not heavily tested. Caveat emptor.

Thank you Pekr and Sunanda for your replies and suggestion on my 
question about unicode and cyrillic. I tried ascii-chart script and 
it unfortunately doesn't show any cyrillic letters :-(  I understand 
you, I have to wait until r3 is released, but I don't want to wait 
for it (as I can see from forum posts it could be not very soon).

Is there any other way to recode cyrilic letters? I mean ANY actually, 
coz I liked the way and philosophy of rebol which Carl wrote about 
in his blog very much and I'd like to be able to write rebol programs 
in my language, but how? I don't look now on any net-spicific programs, 
I want to try myself in very simple program for menu managment in 
my distro (http://www.puppylinux.org). It is Russian development 
of quite well-known Puppy Linux by Bary Cauler, so we need cyrillic. 
As for other languages like C, Python, Java etc - I'm not a programmer 
and (this is why) I really loved the way that "simple things can 
be done in a simple way". My few trials to write a program using 
Glade in Ubuntu were unhappy - it seems like a one big bug, I even 
couldn't make a little program! It seems to me that bash is more 
transparent that Glade sometimes...

Also I begin to understand why there is a problem with rebol popularity 
- absenbse of unicode in Rebol is only one of reasons. I was very 
surprised that there are almost no Russian resources about Rebol! 
How can people begin to use anything - if they cannot even read about 
it in their native language? I think it's a big mistake - not to 
have a translation group for Rebol - like one in Gnome dev, KDE etc. 
I could participate in it and to help promote Rebol in Russia, but 
it is a huge work which could not be done by one or two men, and 
surely, I can't start such a project - I think it should be done 
by you, Rebol-gurus. Then, you could coordinate translations and 
we could begin to make Rebol more international and popular. P.S. 
Not sure this is a right place to write about, but I didn't find 
something more suitable...

It is sad - I even can't start a Russian group here where people 
could write not only in English, but in Russian too. ALTME doesn't 
support cyrillic as well. No need to say that without unicode support, 
without ability to interact with other programs/processes from parent 
OS Rebol becomes almost useless for masses...

Wait for Rebol 3

You'll be a great tester for Unicode support in R3 Alexandr. :-)

Great example of a DSL Gregg.

If you want to translate the documentation, I have copied the wiki 
to another wiki at http://www.compkarori.co.nzwhich has multilanguage 
support

The current mediawiki is too old to support multiple languages

Since it is a vm, I can make the whole thing available for download 
sometime.

Jerry Tsai was able to display ChineseJapanese and Korean text in 
Rebol. So it's wouldn't be impossible to dislay cyrillic text, just 
very difficult.


Here's a glimpse ... http://jerrylovesrebol.blogspot.com/2008/01/animate-tabbedpane.html

what technic he used ? some images of ideograms ?

Jerry using R3

holy sh*t, who he killed he to have a copy of R3

no one, the current alpha release has unicode support

the first one ?

the graphics subsystem was done ... just no VID

hum it''s currently bugous, even the subsystem

i tried caret-to-offset, offset-to-caret, it doesn't work

Jerry didn't wait for r3. He did this in May 2007  - http://city.udn.com/v1/blog/photo/photo.jsp?uid=JerryTsai&f_PHOTO_ID=774988

It was reported on The Rebol Week by some fellow called Graham ;-)

different

see his screenshots of chinese in the R3 console

i over reacted, i'm not currently intersted by unicode ;-)

i made some test to build an RTE editor using gobs, but as i said 
the current alpha is bugous

well some decisions were made.

so we should see a public release very soon ....

need a site to host the BBS and to select one.

probably phpBB3

Thank you for hint. But unfortunately current alpha release I have 
found is only for Windows and I don't use it :-( At least I had no 
luck to find rebol3 for Linux

Alexandr: < I tried ascii-chart script and it unfortunately doesn't 
show any cyrillic letters>
What I did that showed me some cyrillic was this:
** download the ascii-chart.r script from rebol.org
** change this line
     [append hex-lo [box 25x25 blue]
to
    [append hex-lo [box 25x25 blue font-name "WP CyrillicA"]
WP CyrillicA

 is a Cyrillic font I happen to have installed on my Windows PC. Any 
 Cyrilic font you have is likely to have a different name. When specifying 
 the font name it is case sensitive.


If this works for you. it may also help for many VID styles (BOX, 
BUTTON etc) It probably won't help for ALTER and other pop-up boxes

Alter!?
I mean ALERT of course.

I have found some errors in the rebol wiki book.  I sent themto Carl 
but he must be far too busy for this sort of thing.  The falws failed 
in 2.7.6 but failed with different result in th eold 3.0 alpha
Is anyone here on altme interested in the wikibook ?

wikibook?

Carl has nothing to do with the Wikibook. We have an old group for 
the Wikibook.

Yes, a few of us here are authors for it

It was written before R3 was announced. I don't even know if anyone 
has updated it since then.

we should move the wikibook to the new wiki once it is up and running.

Richard has offered us a PC to host the web BBS and new wiki

we should be able to use wiki tools to download it and I can then 
upload to the new wiki

Sunanda, thanks for your help. Anyway, I tried all my fonts, which 
do have russian (cyrillic) letters, but still had no luck. Seems 
I really have to wait for Rebol3 as nobody knows how to solve this.
