World: r3wp

and cpp, + .h files all mixed up...  and a dll for some funcs...

so no special math functions?

I don't know... but mathlab has a compiler which is supposed to allow 
creationg of C object modules or dll files for easier integration 
outside of mathlab... (thats what it says on the web site anyways)

yes, it came after version 5, the last I used was 4

I once "translated a matlab script to Rebol and was amazed how Matlab 
computed square-root

square-root -4 is -2 according to Matlab

is square-root -4 even possible?

cause  -2 X -2 obviously doesn't amount to  -4  ;-)

exactly, that was the reason why I was surprised, nevertheless the 
author of the program was content with it, so I had to "translate" 
to Rebol as follows:

(sign? x) * (square-root abs x)

eeks..

anyway I doubt about the correctness of such a program

yet there lies a paper which has code along with it which allows 
us to select obects in an image merely by painting vague strokes 
on them...

and its coded in mathlab...

square-root -4
 only exists with complex number, not real one.

yes, the correct result is an imaginary number 2i

ahhh

Seems that request-file/file  doesn't work

EE degree is based on the square root of -1, to create sine waves...but 
in high school the Algebra teachers told us it was just imaginary...so 
I guess I have an imaginary degree.

Anyone know how I can find my password for the Developer IOS server?

nevermind I think I found it

Had to change the registry entry to the correct path.

was there another outage about 20 mins ago ?  I see everyone who 
was on logged off at the same time - including myself, involuntarily

yup

Can anyone give me a good tip for a free tape backup program that 
is able to backup workstations (windows) on a LAN via UNC names like 
\\my-system\c$

why not just script it up with rebol?

How would rebol connect to the taps driver ?

*tape

I wasn't thinking of tape actually, I was thinking more along the 
lines of backup to other harddrive storage

Bo has written such a utlity .. that also backs up to a ftp directory

I have a program I made myself also.

It would be nice for a rebolish way to interface to tape drives and 
dvd writers

Yeah - Carl should try to chime in sometime on some suggestions on 
how to do that.

Graham, right, I need to access the tape. The next problem is to 
handle things like: open-files, system state for Windows machines 
etc. IIRC Windows provides an API for backup-programs. If you want 
to do live backups of things like running DBs or Exchange etc. you 
need special APIs as well.

Hi, does someone know a good development environment which can create 
DLLs and simplifies COM programming? I want to create some wrapper 
DLLs for Rebol that use COM objects. But I really don't want to hack 
through MBs of MS header files etc.

Borland Delphi. They have an Open Edition that is no-charge.

Hmm... my Pascal knowledge is a bit rusty ;-)) Thanks.

My son Josh wrote a tutorial on this.  I don't remember at the moment 
exactly where he put it, maybe on his web site, but I will find out. 
 A very simple, to the point how-to.

...well, I don't remember if .com   (sorry)

it was some free download c compiler.

Gregg mentioned somewhere he uses realbasic. Blackbox Builder was 
proud about it too and is now open source. but have not read enough 
docu.

There's a Free clone of Delphi out there called Free Pascal with 
a GUI-alike called Lazarus, but I doubt its COM support is that good, 
and they can't do the GUI as well because the best features of Delphi's 
GUI are patented by Borland. I think Microsoft licenses those patents 
for Visual Studio.

Robert, I'm not sure if this will be helpful, but this is what steve 
was talking about:  http://www.cs.grinnell.edu/~shirema1/docs/DLLsinREBOL.html

Josh, thanks for the link. My problem isn't creating the DLL part 
but getting the COM part done in a simple way. Writing the wrapper 
for Rebol is done quite fast.

Anyone know any other languages that are similiar in design to REBOL?

Similar in which way?

Where you can define words and use them in dialects

Forth

Do you mean that it has a bnf parser included?

Nemerle

Though with that, the dialecting is done at compile time rather than 
at run time. Not quite the same, but still much of the language is 
dialects in the REBOL sense.

Lisp ...
