'ANY on returns a non false or non none value.  it does not return 
such a value from the block itself. if you specify only none and 
false value, it effectively assumes all is bad and returns none.


'ALL is the same, but will only return a value unless one value equates 
to false or none (in which case it considers the block a failure 
and returns its own value, not the value from the block itself).

Gab, the same applies for:

This doesn't look very consisten to me:

>> to-integer none
== 0
>> to-decimal none
** Script Error: Invalid argument: none
** Where: to-decimal
** Near: to decimal! :value

yes, i agree. i think other cases like that have been pointed out 
in the past.

I don't know how INDEX?/XY works. Help, please.

(is it meant for IMAGE! datatype?)

Ladislav: it seems so:

>> n: make image! 100x100
== make image! [100x100 #{
000000000000000000000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000...
>> n: skip n 300
== make image! [100x100 #{
000000000000000000000000000000000000000000000000000000000000
0000000000000000000000000000000000000000000...
>> index?/xy n
== 0x3

thanks

I'm curious, if there's also some function for setting position in 
image! - something like AT/xy

There is:
>> at logo.gif 12x10
== make image! [100x24 #{
7C7C7CF5F5F5FEFEFEFEFEFEB5B5B5020202020202020202020202020202
020202020202BDBDBDFEFEFEFEFEFEF5F5F5A5A5A59B...

Ah, thanks

>> index?/xy at logo.gif 12x10
== 12x10

How should the above line be written when the user name is an email 
address?

You should find the answer here: http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-topic-index.r?i=mail

or here:

Thank you, Peter!

Problem: no matter which email client I use, only 8 emails can be 
downloaded. On the 9th email the client locks up. What can I do about 
this? I am expecting some very important email.

Try dowloading DideC's excellent delete-mail program - http://membres.lycos.fr/didec/rebsite/delete-emails/delete-emails3.0.0.html

It will let you look at the headers of the mail in your mailserver's 
inbox.

You can delete messages that are causing problems before you dowload 
them.

Thanks, Peter. I'll try that and let you know what happens.

There''s a more up-to-date version at http://membres.lycos.fr/didec/rebsite/delete-emails/delete-emails.r

Some code is missing in DideC's script.

Whoops. Didn't see your post in time.

Error message says the site might be down.

No. It opens now.

I'm not having much sucess today. I downloaded it, but it dies instantly 
when I try to fetch my mail.

Erro Signature
AppName: rebol.exe	 AppVer: 1.3.2.3	 ModName: rebol.exe
ModVer: 1.3.2.3	 Offset: 00031983

That is a windows error message, and just the first part of it.

Is that script working for anyone else? I mean that version of the 
script?

I run version 3.1.1 with Rebol 1.2.10

I'm running: REBOL/View 1.3.2.3.1 5-Dec-2005 Core 2.6.3

I'll see if I have an older version on my harddrive somewhere.

I also downloaded the latest version and got a similar error on 1.3.2.

Louis, try this:

do http://anton.wildit.net.au/rebol/util/preview-mail/preview-mail.r

Script: "view-message" (2-Aug-2006)
connecting to: anton.wildit.net.au
** Script Error: Cannot use path on none! value
** Where: open-window
** Near: win-pos: prefs/data/win-pos
if all [block? win-pos main-pos: win-pos/main]

system/version == 1.3.2.3.1

Thank you Oldes. It looks like the problem is that somewhere there 
is an assumption that the prefs have loaded from disk. Hang on...

Ok, bug fixed.  Try again, Louis.

(The script is now one word shorter - I love bug fixes like that. 
:)

I managed to get a working copy of Didec's delete-emails to Louis 
by pasting it in a private message. It seems to have allowed him 
to resolve his problem.

Ok, very good.

PeterWood and Anton, many thanks! It turned out that one of my children 
sent me a file with many huge photos. The very slow dialup connection 
I have here in Indonesia could not (or perhaps is designed to not) 
handle it. I was able to delete the file and all is well, except 
that now I can't look at the photos, at it cost me two days trying 
to solve the problem. I probably could not have solved it at all 
without you guys.

User poll

How many users would like (or at least not object against) adding 
BUILD as an official mezzanine?

Comparison of BUILD and REDUCE/ONLY:

1) REDUCE/ONLY does not allow you to specify which words to evaluate, 
which would be safer, it rather specify which words to *not* evaluate
2) REDUCE/ONLY isn't /DEEP, i.e. it does not process subblocks
3) The evaluated words are local for BUILD

http://www.fm.tul.cz/~ladislav/rebol/build.r

(How many users would use BUILD?)

would that mean:

>> build [1 [3 + 2 now]]
== [1 [5 13-Oct-2006/11:16:56+2:00]]

?

because that's the kind of build I would be interested in

hmm... no it wouldn't. :-(

I don't have anything against BUILD, but I need to be convinced more 
on the practical uses, because I can't see how this makes block building 
any easier. Perhaps some more examples would be good. :-)

Examples contrasting compose (with /only and /deep) and reduce/only, 
would be great. I know it has a couple in the script. I've looked 
at it in the past, but haven't been driven to add it as a standard 
part of my process yet.
