its supposed to put out over 11000 mg/hr of ozone or what they call 
aran air

I  know someone who had a water issue on their cement, and when they 
started asking around about the white mold which was appearing on 
the surface, they where told to leave the house and call a professional 
cleaner...  it turns out, killing the mold was easy, but when dying, 
they released spores which are extremely dangerous and can suffocate 
a majority of people before you have time to get to the hospital... 
 :-(

perhaps call/console ...

I tried call/console .. but to pass the control-C back, I have to 
input that into the dos shell window and not the console.

REBOL cuts out the bureacracy of UML and implements direct.  Schler-Mellor 
and Grady Brooch have some "noble" goals (but the devil's in the 
implementation), but have never faced anything as powerful as REBOL 
yet for implementation.  I saw Mellor talk once, and he did a great 
talk on "orthogonal behavior" which is apropos.  I think the way 
to utilize their mess is to do it simpler in REBOL, call it UMLR 
and teach them the future.

EVRC 8k gives almost the same quality of voice as QCELP 13k, thus 
in USA, for CDMA, EVRC is used to increase voice call capacity.

Ideas are: 

1) timeout could create an error, leaving some resources in wrong 
state. A lot stuff in the input-buffer could trigger an buffer-overrun.

2) processing in /awake (if you use that) could not be correctly 
registered in gc. either gc misses some reference, or finds some 
reference on the return-stack which is not actually a reference. 
because the gc expects a call from a rebol-native and is instead 
called from a normal c-one.

Mike, for the record, this is a gray area.  I am in fact saying Graham 
is full of crap, but for a subjective opinion.  To actually be an 
attack of him as a person (ad hominem) I would have to say something 
about him, as opposed to about his method.  This is a rather meta-argument 
because the very thing I'm attacking is his debating skills. 


I happen to treat software as people (my own quirk), since it embodies 
the spirit of the creators.  As a result a consider some statements 
attacks.  I'm fine with a factual statement. But if I do not call 
attention to this, it becomes lore.


Gab, there is not a perceived lack of on-going development, there 
has been in fact almost no development for long stretches of time 
on AltME.  That simple.   Does not address the issue, and a disagreement 
is not a flame war.  I have too much respect for Graham to flame 
him.

So its a matter of control then. You want all the worlds and clients 
to call home. Thats fair, its your business model but I also thought 
that you mentioned that there would always be a free version of altme 
so I didnt think it mattered anymore if a small community, because 
of infrastructure constraints, prospered within a firewall.

I see Altme has an open folder icon, and this uses a system call 
to open up the local folder.  I can see the dos box open up temporarily.

That is what we call the "rebol" bug.

i guess he simply uses an os-call to launch the right app. Where 
the app is choosen by the os, based on filetype. And a *.bat runs..

If you can issue a DOS command (REBOL/Command or some betas with 
Call enabled), try this:
    echo ^l > prn
(That's a ctrl+L character, not a caret then L)
That should force a form feed

debugging: IIRC I once asked this question already but can't remember 
the answer. Is it possible from inside a function to get the set-word 
this code is bound to? I would like to be able to print the set-word 
for debugging call-traces.

This is one of my more major problems with REBOL - it is an internet 
language as advertised so you assume tasks like this would be simple 
or for example enumerating connected or listening ports, retrieving 
a routing table etc.  At least I can use call to get some other application 
to do it for me.

You could always use CALL to get this info and the parse it.

yeah I know I actually have to do that now with a call to netstat 
-aon

You could always use CALL to get the open ports on the host system 
and the parse it. What OS? Do you want support for?

Lower level access in rebol is only possible either through CALL 
or via a SYSTEM CALLS using the DLL access.

The CALL function really helps now though

with a system call

Though having just tried it......it didn't work either.
Looks like an older name for call

run will call a native application to open the file in question eg. 
acrobat reader for pdf files.

It is only enabled on IOS .. I have asked RT why it can't be enabled 
for the sdk as well.

Clever!
But crucially dependent on the block being contained on one line:
 xx: {
 do do replace/all mold [1 2 3
  4 5] " " " + "
 }
 do xx

But then you did call it a one-liner :-)

But why would an actor call himself after a broker?!

Some say tomato and some say tomahto
Some say potato and some say 
potahto
Tomato, tomahto, potato, potahto
Oh, let's call the whole 
thing off

I guess I can call agg-view.exe to do the graphing that I want

I asked Anton directly but some of you may know a work-around. I'm 
using his scroll-table style but when I call a face using it within 
a reblet it does not "do" it. It works from the command line with 
a "view face" but not within. Is there something akin to "reduce" 
which would, for lack of a better phrase, force a face to recompute 
itself entirely? I tried "show" and "focus."

Rather than storing the HL7 result as free text, to store each sub 
test in a database.
So, a Hb result will be stored as a Hb record.

Another laboratory might call that "haemoglobin", so I need to map 
these two together.

call reduce [system/options/boot "argument"]

best way is call the lpr command

if you know you are on kde, you can also call kprint (or was it kprinter) 
and it even displays a nice ui for print options.

For the browser i use this in my user.r

browse*: :browse
browse: func [
	value [any-string!]
	/only
	] [

   call rejoin[{/usr/local/firefox/firefox "}  to-url (value) {"}]
]

when the fax is received, it invokes a bash script.  But I just remembered 
that I also call my rebol script from that bash script that creates 
the file in question.  So, I should be able to make it readable to 
my other script to ftp it to me.

Hi Phil,


*nix doesn't use drive-letters, so _all_ drives show up somewhere 
under the root as directories. _Where_ they show up is up to you 
;-)

Drives are "named" /dev/hda1 (first paritiion on first disk), /dev/hdb3 
(third partitiion on second drive), etc ...

There's a file, which describes the mapping, where your drives are 
put, in Rebol

print read %/etc/fstab


the first two columns show where ich drive is put in the directory 
tree (and then some more info)

or you can do 

call "mount"

which displays the currently mounted drives.

Alan; the sensible-browser seems to be a Debain branch feature.  
It's GPL so we can work that out.  The hint I left for the RAMBO 
folk is to internally call sensible-browser.  This won't work for 
us until RT does a build.  Once/if that is done, we can talk/plan 
more, about documenting getting browse native functioning.


In the meantime, try the  browse: [url /only] call reform ["path 
to browser command" rejoin [{"} url {"}]]

redef.  If you know the switches for your browser, you can even code 
this to support /only.

I changed my /etc/rc3.d/S99local to call cheyenne.r but now although 
it starts up cheyenne.r, I now don't get to the Gui login for fedora 
...

just use core to call imagemagick

I found that giving large amounts of text to a CALL, causes a permissions 
requester so big that the buttons to allow the action are put outside 
the window and by resizing it, 1-2 pixels of the buttons can be seen, 
but are unreadable. Anyone spotted this?

Does vmware under linux not compile some modules during installation?
So just call the install script again and see what happens.

Is this going to break anything for getting a valid status code out 
of call?

cap: func [calls /local sherr status] [
    sherr: copy ""
    append calls { ; echo -n $? >&2}
    status: call/wait/info/error calls sherr
    status/exit-code: to integer! find/last/tail sherr newline
    status
]

Of course this is stripped down  (the whole /console /output etc, 
combination thing to handle), but it seems to be working for getting 
at exit status.  Dirty pool? cheap trick? or functional?

Gabriele; any hints or comments?

How can I get back the output of a shell command? I tried:
>> procs: ""
== ""
>> call/output procs "ps -A"
== 100
>> ? procs
PROCS is a string of value: ""

Got it. The call is:

call/output "ps -A" procs

If you need more control, Gabriele and Doc have a great async-call 
module.

I'm using call and call/wait to invoke gs to convert ps files to 
pdf.  Anyone know why the return code can be non zero on linux and 
yet it is still doing the conversion??

CALL has a bug in Linux (and other Unix), it just returns a random 
number...

Carl knows about the call linux bug since quite some time... and 
I have provided him with what I think could fix it (but I have no 
way to test the fix). Qtask needs this bug fixed too, so one can 
say it's reasonably high priority. :)

Paul;  yep, leave the Money Suck corporation behind ... send money 
to RT instead.  :)   And umm, it's ubuntu ... something about peace, 
live, share, "be human" in Zulu.   It's nice but it's not Debian. 
  Love the non-obvious pronunciation names.  REBOL, Debra and Ian 
for Deb-ian  and ooboontoo  or some such.  :)  And here I am stuck 
on a Win98 box and Carl just fixed CALL on the Linux side  :(

You could look to 'copy-modes but I doubt it

Otherwise you'll need to call/info with one of the bash test commands. 
  -h I think.

in that case, I'd shell script the tests and then  call/output  it

yes... I call stats quite often.. it's part of my test function which 
also counts time required to eval the script I test. If there is 
momory is expanding, I know, that something is wrong in the script 
quite soon. (but I code almost in core, in view it can be more difficult)

What makes a good dialect? That's a hard question to answer. What 
makes a good GPL (General Purpose Language)? There is no formula 
I know of, but I would say it should be:


* Focused. *Domain* specific is the key. If you don't know the domain, 
it will be hard to get it right.


* Well thought out and refined. Don't just take the first pass and 
call it good. Like a writer, think about the words you choose and 
how they're put together. 


* Small. Think about how the language will grow, but don't try to 
put too much in it.

Robert, if you don't want to use parse rules you might try DO/next. 
Don't use DO/next (or Gabriele's compile-rules) if your dialect data 
can come from an untrusted source - use parse rules and dialect operations 
that call the REBOL functions if necessary.

It looks like the event function isn't being triggered for the box, 
but rather for system/view/screen-face or something -

>> ke: func [f e][if e/type = 'time [print f/text]]
>> insert-event-func :ke
>> view layout [box "Testing" with [rate: 1]]
none
none

None of them print "Testing", as a call from the box should

The event handling system will call your insert-event-func handler 
as fast as it can, if there are availalbe events, and there will 
always be time events, occurring at whatever rate REBOL uses them. 
I don't know of any way to control when, or how often, your func 
is called.

If you want to get a job as a grunt programmer in a big company, 
using whatever tools they tell you are in fashion, REBOL is not the 
right tool for you--though it may be a nice support language. If 
you want to think about hard problems and algorithms, it's as good 
as Lisp/Scheme within limits (e.g. tail recursion), and easier to 
play around with. If you want to get the job done and either make 
the tool call yourself, or can convince the people who do that REBOL 
is up to the task, it's great. And if you aren't a CS major, but 
know that computers and programming will affect you in business, 
and you want to be able to to some "light" programming, I think it's 
great.

Yeah, with braw I wasn't concerned with the 2 opcodes you would have 
to add before any call to braw to make it usable; I was more concerned 
with actually being able to get the address offsets to compute with 
without having to write a compiler (which I am going to do anyways, 
just not right now). That was why I came up with that HERE assembler 
directive.

so you could e.g. convert rebcode to dll and redirect the call, to 
get native C level speed? Hmm, sounds like there are some options 
for the future :-)

I am talking speed ;) Your example goes thru a rebol-style call. 
a direct call may be much faster

It would be interesting to have a parse opcode, but keep in mind 
that this kind of speedup would likely be implemented in the JIT, 
when we get that. And however fast parse is, its overhead dwarfs 
that of a function call. And remember, using apply would be significantly 
faster than calling a function in the do dialect because there isn't 
any evaluator overhead.

APPLY may be good for thinks like reading from network or so, that 
cannot be done in rebcode, but it's not useable as subroutine call 
in rebcode, it's too slow.

Was anybody testing if what is faster, if rebcode or c-code call 
using dll?

Hey, Volker's got it! Use version 3, but call them add-i, sub-i, 
...

Actually I based it on your skype.r app. All it does is set the audioin 
and audioout settings. I have a Plantronics bluetooth handset and 
earpiece but it doesn't support Skype voicemail messages so every 
time I received one I had to go to the tools and switch out the audio 
to my computer speakers and back again. It also seems to cause some 
slight interference when I had to enter touchtones so I wrote this 
little gui that simply lets me change those. Nothing special but 
it is a real time saver and with the touchtones a call saver since 
you have to enter tones pretty qucikly sometimes.

maybe a 'bridge' for REBOL-Ruby.


allowing Ruby to call or access REBOL 'objects' directly and vice 
versa.

Volker, compiling Rebol is not impossible, it is just very difficult 
exponentially difficult because " the order evaluation" for the a 
function call can change at any time. Depending on how the words 
in the body are defined. This is the CFG feature and problem.

No, i want my program to have s much determinism as needed. I call 
"perfect determinism" when i know "this stuff is done on cpu3, then 
the other thing a bit later on cpu4". That is perfectly repeatable. 
But that is not what i need. "this stuff is done on the next free 
cpu" is enough. But to do that, i need a language which can determine 
what this next free cpu is. And for that i need a general purpose 
language (counting cpus, acountig used time, priorities etc). While 
you said general purpose is not needed for a coordination language. 
But maybe i miss simething, maybe coordination means something different?

Henrik - very strange, really. In our company, USB drives (flash 
drives) are really a boom. We can see problems VERY sporadically, 
if ever. I would definitely refuse to call them unreliable - much 
more reliable than anything else - floppies, cds/dvds

There is a new scripting language in development called F3 from Sun, 
specifically designed for GUI programming. It allows designing Flash-like 
GUIs with ease and can call Java libraries directly. You can launch 
demos and get more information from the related blog. - http://blogs.sun.com/chrisoliver/category/F3

Well, I just said they have their own VID. In comparison to what 
would be needed to achieve the same using pure JAVA code, I would 
really call it a simplification, which might help some guys ...

IIRC it can even multithread code with no threads within the source! 
 sort of because of the way it distributes processing.  IIRC each 
operation is a single call and if the kernel detects that it can 
push a few ops in parralel it sends all of them at once... so single 
process code can actually run on multiple CPUS with no programing 
on your part.

Furthermore, I sometimes have the problem, that errors in sql statements 
are not caught by try, if I call it from a view gui. 
Is this a known problem?

Thanks Brock. Robert, looks like you've hit the same error I RAMBOed 
here: http://www.rebol.net/cgi-bin/rambo.r?id=4063&


A real pain as it can be consistently reproduced (and hence avoided), 
but with no pattern [that I can see]. If Carl implements SQLite-like 
support (see latest blog entry) then hopefully this will become a 
moot point as we won't require the library call anymore.

I'm thinking about updating to the newest SQLite version. And I just 
read there is a new API which should be used.


The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are 
recommended for all new programs. The two older interfaces are retained 
for backwards compatibility, but their use is discouraged. In the 
"v2" interfaces, the prepared statement that is returned (the sqlite3_stmt 
object) contains a copy of the original SQL. This causes the sqlite3_step() 
interface to behave a differently in two ways:


If the database schema changes, instead of returning SQLITE_SCHEMA 
as it always used to do, sqlite3_step() will automatically recompile 
the SQL statement and try to run it again. If the schema has changed 
in a way that makes the statement no longer valid, sqlite3_step() 
will still return SQLITE_SCHEMA. But unlike the legacy behavior, 
SQLITE_SCHEMA is now a fatal error. Calling sqlite3_prepare_v2() 
again will not make the error go away. Note: use sqlite3_errmsg() 
to find the text of the parsing error that results in an SQLITE_SCHEMA 
return. 


When an error occurs, sqlite3_step() will return one of the detailed 
result-codes like SQLITE_IOERR or SQLITE_FULL or SQLITE_SCHEMA directly. 
The legacy behavior was that sqlite3_step() would only return a generic 
SQLITE_ERROR code and you would have to make a second call to sqlite3_reset() 
in order to find the underlying cause of the problem. With the "v2" 
prepare interfaces, the underlying reason for the error is returned 
directly.

Well - there is btn-sqlite (better than nothing) driver on rebol.org 
It works, with one bad effect - black console window appearing during 
the shell call. Just recently I put it on high priority list for 
W.7.6 to be fixed - all is needed is to set one flag for shell call 
....

Will, did you try modifying the following lines in the driver:

	*lib: load/library ... ; to call the correct version

 *prepare: make routine! ... ; to use "sqlite3_prepare_v2" instead 
 of "sqlite3_prepare"

call, I mean.

Ashley, I just remembered that you can't call CONNECT/CREATE several 
times in one application. It gives the error "Database already connected" 
even if you use different file names.


To open more than one database file you have to use the sql ATTACH 
command starting from the 2nd database file.

I think makeing CONNECT handling this case implicit would make a 
lot of sense to make it simpler for users. So the programmer know, 
it's possible to alway call CONNECT/CREATE. What do you think?

I see one problem, if the to-be-opened database doesn't exists yet 
it needs to be created. This can only be done by a call to sqlite3_open 
and not via the ATTACH sql command.

i am saying 
  call/input/output "rebol %trusted-requester.r" 

Where the call is hardwired like 'browse and can not be influenced 
by reblet.

To simplify the issue, let me pose a scneario. Joe has a fresh copy 
of XP, no REBOL nothing. He clicks on a .r file. You want the plugin 
to install itself and open the .r file inside the browser window. 
Am I understanding your goal?


No, I want it wrapped.  The ".r" is simply a reference point, since 
we don't have a word for a Rebol executable script.  Want to call 
it ".rrs" (Rebol run script) or something?  Flash calls theirs SWF, 
FLV, etc.

Josh is it possible to call rebol function from javascript ? i.e. 
expose a function "eval" so when I click an html button I can call 
a rebol function.

As a suggestion for dealing with proxy issues, why not have the plugin 
dll read the browser's proxy settings and then call the View dll 
with some REBOL code that would set its proxy settings accordingly?

my understanding is that it is the C code, wrapper for the browser. 
It would have to call View dll with some packed-in rebol code then 
to "preconfigure/patch" some mezzanine code ...

security vs useful ... I know it's a tough call. Just pointing out 
how some of the multi-services from different domains is so common 
now. (just disable 3rd party cookies in your browser to see how many 
warning message you get)

It is also likely, and I should be clear, that some behaviors related 
to the browser handling of things like events may be somewhat different 
than in REBOL itself.  This is related to the fact that explorer 
is handling the events and sending them to us via a type of "relay" 
(we call it a window proxy).

Hmm, for reads we could 'call wget, at least for reading.

you can call javascript and  get back a string AFAIK.

I simply want my index.html (or other) to be submitted to mine registered 
cgi, which I call rsp.cgi. This "dispatcher" looks into list, if 
this page is registered as dynamic, and if not, returns requested 
html page directly, or scans it for module names, which are then 
loaded and know what to do. I simply want my gfx man to have free 
hands, not requiring to fill any rebol code into templates - just 
marking sections ...

Terry, in my todo-list, I have a generic module for interfacing cheyenne's 
HTTPd with REBOL applications called mod-map-url (or mod-mapping). 
It will map predefined URLs to REBOL objects. Example: http://domain.com/app/show
will call the function ''show from your object 'app. This module 
should cover most of needs if you have to embed Cheyenne in your 
REBOL application. If it doesn't cover your specific needs, you'll 
have to write a specific mod_xyz HTTPd module, which might be a little 
more complex.

I'm not familiar with RSP, but it seems it's loaded one time then 
run with the webserver (not like cgi that are loaded on each call).

So maybe it just need to be restart to handle already corrected code 
!?

Brock: well, I guess that's maybe because, sometimes, the "cure" 
can be worst than the desease, so you might want to call it a "curse". 
;-)

We must be really in strange situation, when Carl invites someone 
like me (which I call a mistake :-) to r3-gui, to actually get some 
real feedback!

Nick, tomorrow I will help push a final call for everyone.  I guess 
right now this will be on the small side.

Reichart, the page looks great :)  I haven't heard from any other 
presenters, and do need to reserve bandwidth today.  How long will 
you, Chris, and the Qtask team need?  LAST CALL for presentations!

Paul, is that near the tornado belt (or what you call it)?

What I would do though, is to distinguish the numbering of Devcons 
- I would not call it fourth devcon, but first virtual DevCon. OTOH 
even with "phasical" devcon, many ppl do attend virtually anyway. 
So what do you think about that?
