Ah - it's clear - it is waiting on when they will be finished.

Hm... but is it possibe to do so that  interfaces is keeping to be 
responsive while another function/task is running?

Not easily. You have to launch another REBOL process, send it the 
request, let it do the blocking calls to ODBC then send back the 
results.

Btw, why are you using ODBC to connect to a MySQL server ?

Yes - know that you will answer that! ;-)

Quite old story, I had command version and not yet knowledge about 
Softinov mySql driver, and I used it to access also MsSql

And you had some issues with the /Command version, I guess ?

What issues you mean?

/Command has a MySQL driver built-in, as you're using ODBC, I'm just 
guessing that the MySQL built-in driver didn't fit your needs.

I needed it for very simple tasks, so it does what I need. But I 
did not yet tested f.ex. speed.

ODBC adds some overhead compared to a direct driver.

But I used Softinov in other apps. The new version is very nice. 
Very easy to code extraction of values from field names.

Glad to hear that it serves you well.

While you're there Dockimbel, I've always wanted to know how one 
checks for the mysql port being open. Occasionally my apps meet with 
a closed port and die.

good question - the same interest me too

try?

answer in MySQL channel

Janeks, you may have missed it, but /Command also has a native MySQL 
driver (so you don't need ODBC for MySQL). (That's what Doc was trying 
to say :)

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.
