REBOL doesn't support this kind of syntax:

->> i: 1
== 1
>> j: 2
== 2
->> blk: [["A" "B" "C"] ["D" "E" "F"]]
== [["A" "B" "C"] ["D" "E" "F"]]
->> blk/:i
== ["A" "B" "C"]
->> blk/:i/:j
== "B"
->> blk/:i/:j: "Q"
** Syntax Error: Invalid word -- :j:.
** Where: (line 1) blk/:i/:j: "Q"

->> change blk/:i/:j "Q"
== ""
->> blk
== [["A" "Q" "C"] ["D" "E" "F"]]

Is that what you wanted to achieve?

[REBOL] [REBOL] Prime number generator

[rebol]

G'day, folks  I've been enjoying the discussions on [EMAIL PROTECTED]  It is 
obvious that the flexibility of REBOL unleashes a lot of creativity. I am 
still trying to get my head around  some of your discussions, but here's a 
start..

I was testing is-primes? that comes with the REBOL Core 2.2.x distribution: 
%is-prime.r  and found that it comes up with the following:
>> is-prime? 341
== true
>> 341 / 11
== 31
>> 561 / 11
== 51
In the process I wrote a prime number generator %primes.r  which defines a 
function primes [N] that returns a series of primes from 2..N-1 and posted 
it to rebol.org category math. I hope it comes in handy. 
Comments/enhancements are most welcome!

 I have one question, though (several actually, but this one will do for 
now, I think :)
[flags/:mult: 0  gives this error
** Syntax Error: Invalid word -- :mult:.
** Where: (line 45) flags/:mult: 0 ;-- this does not work. why? NV 6/2/2000
This stumped me. Earlier I had declared [mult: make integer! 1] Surely, it 
is in scope.
I was trying to set the "mult" th item in series "flags" to 0 . I got 
around that by using the "remove" and "insert" methods. If this type of 
problem was discussed elsewhere, I missed it. Please let me know where to 
look...

kurzy.bat

We even managed another app to wait untill the rebol part of the task is
not finished by using start /w

I tried to run REBOL from Netware login script. It runs, but on some
machines we get black Rebol console screen. Once you begin to type,
background changes back to default console b/w coloring. Problems with

[REBOL] FW: Email Extractor Script

[Ed]

 I run a Free Trip to Tahiti Contest on the net and have so many
contestants to respond to that I can't do it individually.  All the
email messages reside in an MS Outlook Folder.  My dilemma is: How to
look inside each email message and extract the email address for each
contestant.  I was thinking I could export all the email messages to a
text file and then write a REBOL script to extract the email addresses.

 Could someone give me an idea what the Rebol script would look like
that would read the text file which contains email addresses scattered
throughout and create another text file containing just the email
addresses?

  Thanks,

Here's a batch file that works for REBOL 2.2.0.3.1:

"C:\Program Files\REBOL\REBOL.EXE" "c:\Program

REBOL 2.2 needs a full path to the script. It's different in REBOL/View.

 Looks like a dos path issue
 
 If I run a batch file from my rebol directory
 rebol test.r
 
 it works fine
 
 from another directory I run
 c:\rebol\rebol test.r
 
 and I just get the command prompt
 
 if I run

 it again works

I'm trying to do with with Core 2.2.0.3.1.

I've tried these variations, while being in the same
directory as rebol.exe:

rebol dns.r
rebol %dns.r
"rebol.exe" %dns.r
"rebol.exe" dns.r"

while being in a different directory:

"C:\REBOL\Rebol.exe" %dsn.r
"C:\REBOL\Rebol.exe" dsn.r

they all just go to the ">>" prompt.

Can type them manually and they work fine.

BTW, is the "%" required on the command line?  Seems to work
with or with-out it.

Hey, Have you tried to add a dos command to your bat file
to change the current directory before the command
to run your script.. It prob'ly seems not worth trying
but dos is different like that. win95 won't recognize my
cd-rom drive but if I first start dos and then windows
my cd-rom drive shows up in windows explorer.

I've tried REBOL/View with a batch file and it works fine. Here's what's
inside the batch file:

"C:\Program Files\REBOL\View\REBOL.EXE" %ChorusLine.r

I've also run from inside a C program, using the "system" function with the

Never mind, operator error.  If the message had been

Nothing that I can think of unless there something undocumented, but it
doesn't take too much to reformat

to-mmdd: func [date [date!]][
   join date/year reduce

   either date/month < 9 [join "0" date/month][date/month]
   either date/day < 9 [join "0" date/day][date/day]
  ]
]

; usage..
to-mmdd modified? %filename

or

to-yyymmdd now
=="2215"

It looks like you could just do something like

Anyone know of any other way to do it?

Your FTP server may be chroot()'ing the account.  If so, you may not 
need the /user/ part of the path.

If your home directory on the server is /user, the server will log 
you into /user and make it look like /.  (The /user part is implied.) 
This is starting to be used more often for security.

See if this works:
save ftp://user:[EMAIL PROTECTED]/myip.txt addr

[REBOL] What Type Of Apps Are You Writting? Re:(3)

[mjelinek]

I'm still "just learning" and am not even writing net-aware apps, but the
reason I like it over any other language I've used (incl Perl) is that the
commands are intuitive (including syntax-less) yet powerful. IMHO it's
REALLY not JUST another language. Java is just another language, Perl is
just another language. To use them and be good with them, you've got to
memorize a whole bunch of syntax and many "simple" things just aren't done
in english-thinking ways. You have to become one with the computer
(language) to understand how some "simple" tasks are to be done. Rebol
provides a language where these tasks are done in terms more closely
resembling natural language (or thought) that any of these other languages.
THAT is how programming is easier (from my point of view).

I have another that is about 9,000 plus the Borland

[REBOL] test program needed

[fuchs]

Could one of you Rebol jockeys write a one-line program (actually any
length) that does the following:

Opens a port to another machine running a similar Rebol program and just
sends and receives data? I am trying to debug a problem with what is
probably the wireless driver on a WinCe machine and I suspect that it
dies when there is sustained data flowing in both directions. I am sure
I could, given sufficient time, do this myself but we are trying to do
this quickly.

Thanks.
