World: r3wp

I'm just looking for the function that decodes the text and returns 
text, and not an object

it's likely to be called by decode-url

there is a parse-url  but it is burried in an objecr and not public/global

yeah, it's in there somewhere

see ?? decode-url

dehex?  (preceded by replace/all text "+" " ")

dehex looks good :)

Remember & < and > if you have any of those in the text. 
Shall be replaced by &, < and >.

graham there is a  web-to-plain.r  at http://www.cs.uoregon.edu/~tomc/
that may work for you

if you have more char enties than just hex encoding

there were some note on it in Core release notes IIRC, de-hex and 
decode-url

the microwebserver at http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=webserver.r
doesn't decode spaces etc so comes a cropper if the file on disk 
has a space in it.

The authors, not mentioned, were "Tyler Booth" "Jeff Kreis" "Bohdan 
Lechnowsky"

http://www.rebol.com/docs/changes.htmlnot so much on decode-url, 
but decode-cgi yes.

how to: create a array of objects ? (like arrays of udt's)

blk: copy []
loop 10 [append blk make object!  [a: 1]]

wow, fast reply. thx sunanda. last question: what syntax I need to 
access e.g.  object array no. 5 or 8  to write values like  blk/a: 
recordset ?

I have a object with - name, street, and country and a database with 
50 records. I would like to store the records into a dynamic object 
array for later reading...

equivalent to above, but a bit faster in execution (maybe you have 
a large block):

blk: make block! 10

loop 10 [insert tail blk make object! [name: copy "<name>"]] ; COPY 
so all objects don't share the same string

objects: copy []
person: context [name: copy "<name>" address: copy "<address>"]

get-record-item: func [n field][copy ""] ; <--- you have to make 
this function look into the database

repeat n 50 [append objects make person [name: get-record-item n 
'name address: get-record-item n 'address]]

thank you anton. this is the code I was looking for :-))

oups, how do I read (after appending) record no. 45 ?   person/name 
 (45) ?

objects/45/name

record-num: 45
objects/:record-num/name
;== "aristotle"

That is putting a GET-WORD! in the path. (eg.  :record-num   )

yes, that's it ! running smoth and fast... thank you very much anton.

no problem at all.

;Isn't this a bug?
>> parse #{000102} [#"^@" #"^A" #"^B"]
== false
>> parse #{000102} ["^@^A^B"]             
== true

>> parse #{000102} [#"^@" #"^A" #"^B"]
== false
>> parse #{000102} ["^@^A^B"]
== true

I think AltMe is escaping some characters... I hope you guys can 
copy it and see the actual problem.

;The problem doesn't seem to exist for printable chars.
>> parse #{313233} [#"1" #"2" #"3"]
== true
>> parse #{313233} ["123"]
== true

;Ah. Never mind I forgot about parse/all
>> parse/all #{000102} [#"^@" #"^A" #"^B"]
== true

is there a way how to "simplify" this? (queue is a list!)

	if any [error? try [tail? queue] tail? queue] [

  queue: head queue ; start at a "meaningful" position in the queue
	]

(I would say it is an implementation quirk)

If queue is a list!, why would [tail? queue] fail ? Can 'queue refer 
to other kind of value than a list! value ?

all [series? queue tail? queue queue: head queue]

>> queue: make list! [1 2]
== make list! [1 2]
>> remove queue
== make list! [2]
>> tail? queue
** Script Error: Out of range or past end
** Near: tail? queue

all [attempt [tail? queue] queue: head queue]

But looks like there are greater problems...

queue: remove queue -- would fix it too...

>> queue: make list! [1 2]
== make list! [1 2]
>> queue: remove queue
== make list! [2]
>> all [tail? queue queue: head queue]
== none

the last one seems to be the best

Is there a command to give the path to the presently used user.r 
file?

One of these will probably help you:
>> system/options/path
== %/D/Anton/Dev/Rebol/View/
>> system/options/home
== %/D/Anton/Dev/Rebol/View/
>> system/options/boot
== %/D/Anton/Dev/Rebol/View/rebview1257031e.exe

Thanks, Anton.  Rebol seems to be looking for user.r in system/options/home 
or system/options/path.  It would seem to be more practical for it 
to look in system/options/boot.

But I guess each directory might need a different user.r.

I trying to get set up to use your dir-utils.r.  Thanks for your 
good work on this.

Louis, I think: 

system/options/path  is the current directory of the shell environment 
where rebol was started from.

system/options/home  is the rebol starting directory, where it looks 
for user.r etc. In WinXP this value is taken from the registry at 
HKCU\Software\Rebol\View\HOME, but only for full release versions 
(like Rebol/View 1.2.1.3.1). I imagine there is a HOME environment 
var set in *nix.

REBOL_HOME afaik
