[REBOL] Block Creation Re:
Hi, block1: [] Each time around, block1 is pointed at a growing block, starting out initially as []. The block is modified to include "text1" each time round. Remember, the thing that is actually modified is the []!!! To see this, try this one-liner: do a: does [loop 3 [blk: [] insert blk 'gold source a]] You should notice that the thing that blk is pointing to is actually growing in the source. block2: to-block "" This code gets evaluated each time, which means that the thing that block2 used to point to (["text2"]) is forgotten in favour of the newly created [].

[REBOL] to-path curio Re:
Hi,
The classic MacOS has a 33 character length restriction on filenames, IIRC.

print replace %anz-visa-statement--.r "--" { [30-May-2000 27-Jun-2000]}

Success.
Last question: Are such filenames legal on other OSs (other than Windows)?

[REBOL] Is é a valid char for use in urls? Re:(4)
(user and pass substituted). This works: read ftp://user:[EMAIL PROTECTED]/resume.html This doesn't: read ftp://user:[EMAIL PROTECTED]/résumé.html ** User Error: URL error: ftp://user:[EMAIL PROTECTED]/résumé.html. ** Where: read ftp://user:[EMAIL PROTECTED]/résumé.html Finally, this does: read rejoin [ftp:// user ":" pass "@" to-url "ftp.melbourne.net/r%E9sumE9.html"] I can: write rejoin [ftp:// user ":" pass "@" to-url "ftp.melbourne.net/r%E9sum%E9.html"] read %/c/anton/résumé.html but upon reading the directory I see the name: r%E9sum%E9.html ! and I can't browse to it using netscape or rebol: read to-url "http://www.melbourne.net/antonr/r%E9sum%E9.html" ** User Error: Error. Target url: http://www.melbourne.net/antonr/r%E9sum%E9.html could n ot be retrieved. Server response: HTTP/1.0 404 Not Found. ** Where: read to-url "http://www.melbourne.net/antonr/r%E9sum%E9.html" I am about to give up on using the e acute (this must surely annoy French users) in the filename, but... Would it be good if to-url converted "é" (and other characters that cause URL errors) to %E9 etc? Could read also take "%E9" and find the file "é" ? I am not really sure what should be, but I am having difficulty. Surely my directory isn't the only one with strange characters in it? Anton.

But getting back to the original question (which is not too clearly worded), it sounds like he isn't getting any error when he enters '0', for example.

[REBOL] REBOL international Re:(4)
What would be really interesting is to be able to do REBOL right to left in Arabic, Urdu or Sindhi. [l'empreinte Druck stampa impressão impresión] is all very well for all you LtoR types but what about the rest of the known world? I guess if you want to type from right to left you could maybe get an editor that does that, then set the words in your language with letters in reverse order. Are there any such editors? Anton.
[REBOL] user defined datatypes?

[REBOL] Re: essay/2
Hello [EMAIL PROTECTED],
The translation of the REBOL expression:
[10 "1234" 11]
could be described by the picture (not REBOL notation!):
{{block! 1 *}}
|
V
10 * 12
^
whoops, surely you mean 11 ?
|
V
{{string! 1 *}}
|
V
#"1" #"2" #"3" #"4"
Keep up the good work!

[REBOL] Re: Passing by reference
Hello [EMAIL PROTECTED], Passing by reference a: 0 ; 0 b: 'a ; a to-set-word b ; a: to-set-word b 1 ; 1 a ; 0 so what is the point of to-set-word if I can then not use it to set the thing? Do I need an extra block and a "do" or something like that? c: to-set-word b c 1 a ; 1 Regards -- Anton

[REBOL] embed html, ibrowse amiga
Hello, My ISP won't allow pre-compiled binaries (non-open source) to run on the server. But I still want to test embedded rebol scripts in web pages (on an Amiga). Who knows how to tell IBrowse where to look for rebol to execute it and make it run embedded scripts? Kind regards -- Anton
