Ammon: "1. It has to be happening during runtime there is no compiling."
load-time and loop-time then? ;)

ammon: "3. If you use a set-word in a context then that word becomes 
part of that context.  If you use SET then it reverts to the context's 
 "parent context" or the context in which the context itself is defined."

Thats the important point: there is no reverting :) and so there 
is no need to keep track of parent-contexts.which is quite clever 
:)

What is the quickest way to transform this :
	[ ["a" 11 #toto] ["b" 28 #titi] ["c" 3 #pim] ]
into this :
	[ "a" 11 #toto "b" 28 #titi "c" 3 #pim ]
???

Fastest, I don;t know.  But this works:
xx: [ ["a" 11 #toto] ["b" 28 #titi] ["c" 3 #pim] ]
loop length? xx  [append xx xx/1 remove xx]
 head xx
== ["a" 11 #toto "b" 28 #titi "c" 3 #pim]

Close to being fastest:
xx: [ ["a" 11 #toto] ["b" 28 #titi] ["c" 3 #pim] ]
x: copy []
loop length? xx [insert tail x xx/1 xx: next xx]
x
A time function to measure the speed of code:

time: func [:f /local t0] [t0: now/time/precise do f now/time/precise 
- t0]

Now you can do e.g.:
time [loop 40000 [
xx: [ ["a" 11 #toto] ["b" 28 #titi] ["c" 3 #pim] ]
x: copy []
loop length? xx [insert tail x xx/1 xx: next xx]
]]
sqlab

foreach b  [ ["a" 11 #toto] ["b" 28 #titi] ["c" 3 #pim] ] [append 
 [] b ]

If you want faster execution you should initialize the block [] outside 
the loop

Has onyone manged to use Core with an iSeries (AS400) FTP server.

I have had no success at work .... it trying to read a folder in 
the IFS (Integrat File System) but the server returns a FTP error 
250.

(I dont have all the details on me at home).  Now looking at the 
FTP error numbers 250 is a normal return code, so I dont understand 
why I am not getting any information back.
I am using core 2.6 under winXP .... and connecting to a Linux server 
is working OK.

Didec, i should do: parse b [any [h: set x skip (h: change/part h 
x 1) :h]]
Philb, try my ftp client

On your website Romano?

yes
i it does not work, try the nlist flag

nlist flag?
I will give your handler a try tommorow ... thanks Romano

Is there a load path for the 'do function?
Anton
3-Mar-2005
[556x2]
You mean like a PATH variable in a dos or unix shell environment 
?
As far as I know, do only looks in the current directory (as returned 
by WHAT-DIR) for relative files.

okay, that's what I thought. I was hoping that I'd just missed something.

It would be easy to roll my own "include" function. I might try that 
as a little project.
Anton

Yes, it's relatively easy. Just don' t think it's going to be quick 
:)

Actually, I don't know what you have in mind exactly so I shouldn't 
comment. But I and a few others have systems of our own, so feel 
free to ask how they work.

Isn't what slim does ? Holding paths for code library (scripts) and 
allowing to just slim/load %script-name.r where the file is in one 
of the folder in slim path !!
I mean Maxim's Slim !

quick newbie question .. how does one convert binary to string ?
no matter .. dehex
Ashley
5-Mar-2005
[567]
Note the subtle difference between dehex and to-string
Gregg

[568]
And, if using a beta with AS-STRING, it's kind of a raw cast that's 
fast.

what is the difference anyway between 'dehex and 'to-string  and 
'as-string ?

>> A: [%23%67%68%69]
== [%23ghi]
>> dehex A

** Script Error: dehex expected value argument of type: any-string
** Near: dehex A               ;dehex doesn't work with blocks
>> to-string A

== "23ghi"                ;to-string converted it to a string and 
de-hex only some of the characters.
>> A: {%23%67%68%69}
== "%23%67%68%69"
>> dehex A
== "#ghi"              ;dehex works on all parts of the string

No idea about as-string, dun have that beta.
er whoops nevermind the first part of it - didn't realize it dehexed 
part right away lol
Hey that looks like a bug - it won't auto-dehex the first part of 
a block, but works on the rest no problem:
>> A: [%70%70]
== [%70p]
DideC

I think it's because rebol think its a file! due to the first percent 
sign
> A: [%70%70]
== [%70p]
>> type? a/1
== file!

anyone got a parse rule that tells me whether the text constitutes 
a fully qualified domain?

Does REBOL/Core (or any other version) support the IMAP protocol?

http://www.rebol.com/core-info25.htmlmentions IMAP and APOP
Graham

There is a difference between the IMAP protocol itself (RFC 2060) 
and the imap:// URL scheme (RFC 2192). At this time REBOL only supports 
the imap:// URL scheme, which has a subset of the full IMAP protocol 
functionality. It handles mailbox lists, message lists, retrieving 
and deleting of messages, and message searches, i.e. it is API-compatible 
to pop://, with added support for multiple mailboxes and searches. 
Move/copy/rename and other administrative IMAP functions are not 
specified in RFC 2192 and not supported by REBOL's imap:// scheme 
at this time.
which is what I posted to the list in Feb 2003
BrianW

Thanks, folks. I know that IMAP itself is a bit of a muddle (based 
on profanities that I overheard from somebody who was trying to write 
a complete IMAP client for another language), but a subset of functionality 
is more than I knew about.

mbox: open imap://userid:[password-:-imapaddress-:-com]
there's a bug in imap as released in the current stable and beta 
versions which Scott and I fixed.
