Yes - I was wrong in my sitation description - I actualy used native 
MySql driver. I just messed it with MsSQL ODBC.

Doc, Question about another process launching - did you mean launch 
process and comunicate with them by using some network protocol?

With struct! I can get a binary representation of an IEEE float from 
a REBOL decimal. But what if I wanna go the other way? The script 
ieee.r in the Library has such a function, but can't it be done with 
just using struct! somehow? So I've got the binary representation 
of an IEEE float and want the REBOL decimal.

For a binary float value in the variable binfloat, try this:

a: make struct! [x [float]] none
change/part third a binfloat
a/x


The third a accessor returns a reference to the binary data of the 
struct. Modifications to the value returned affect the struct. Be 
sure to keep the length of the returned binary the same.

Whoops, the change line is: change/part third a binfloat 4

Do you know how to handle (and compute with) 64 bit unsigned ints?

Brian, you're the man! :-)
That's exactly, what I'm after. Thanks alot!

Maarten, I can't think of a short-cut way to do, what you want. I 
guess, you have to do the bit-manipulation manually. struct! might 
help with something like:

unsigned: make struct! [hi [int] lo [int]] [0 0]


You can then get to high and low 4 bytes with unsigned/hi and unsigned/lo, 
and you can see all 8 bytes with: third unsigned

I made some bit operations, that might help you further: http://home.tiscali.dk/john.niclasen/libs/bit.r

Has anyone done anything to build graphical decision trees, or algorithms?

Can you link to something that shows how that works?

skip to half way thru

clinical maps are ways of achieving outcome driven medical treatments

I guess a vector drawing program is needed ... but there needs to 
be a way to select items and selectively remove them.

so it's not entirely for illustrational purposes? the trees are interactive?

Looks like it

well, I suspect they are static images once completed .. but they 
can be edited

graphviz allows something like that, although I don't think it can 
produce complex boxes like that.

so the point is that once they are done, they are not changed after 
government review?

I don't think so ... I think anyone can alter them to suit changing 
treatments

so it's not really an instruction manual? is it patient specific?

anyway, I think it's a vector drawing package with the ability to 
change elements afterwards and to attach elements to nodes

Bit like a standard idea processor

or mind mapping sottware

hmm.. I'm still not sure where it fits or how it's used. But if we 
stick with the chart drawing aspect: It would be possible to do as 
a dialect, and I think it should be inspired by graphviz.

once you have it as a dialect, you can build an interactive editor 
around it, or code graphs up by hand.

Now that I think about it, I think Chris Langreieter did one

shouldn't be more than 20-30 kb code for the dialect.

I'm just curious where it fits in: I thought it would be a way for 
a nurse to administer treatment to a patient, by following the flow 
chart, but it's a way for a doctor to plan the treatment?

it's a way to enforce evidence based treatment.

ah, so you can see what was done?

or what was done wrong.

Sure anyone can choose to treat how they wish, but there is now often 
evidence to lead docs on how to choose the best treatment.

the treatment you learned at medical school may no longer be appropiate

so the charts can provide documentation of the doctor's decision 
process

no, just a guide

ahh.. found it http://www.langreiter.com/space/3flex

ok, I'm confused :-) we'll stick with the dialect.

looks good

Doesn't look he has developed it further since 2006

written in 2002, with some bug fixes in 2006

Thanks Graham for the 3flex link. That's interesting. Perhaps Henrik's 
Relations-Engine might be something you can use. I myself have been 
tinkering around with it and attempting to parse the data to work 
with a chart making program. In my case I am planning on using http://www.maani.us/xml_charts/
.

I am trying to encap 3flex but have come across a few problems.  
Anyone done this yet?

xml_charts looks interesting but doesn't seem capable of doing what 
I want.  But it might be useful for a website.  Does it do time series?

You'll have to check out all the examples to see it it does.

Has anyone ever seen a view app with several fields and and an area 
 that always minimizes when you hit the return key? In this case, 
I don't want it to do that. I  don't think I' ve ever seen that except 
in this app. What would make it do that?

not sure what you mean. is it like a panel that collapses?

It's actually a contact/address book based on Carl's rolodex ap. 
Basically, where ever you are in interface, when you  hit return 
it minimizes the screen as if you hit the minimize button. Weird.

Graham... Check out http://www.maani.us/xml_charts/index.php?menu=Gallery&submenu=Floating_Bar

If it's a custom app, they could be grabbing the enter key and minimizing 
it. But that seems like a really bad idea, so maybe just a glitch?
