Hi George,
There is a project on sourceforge
(http://sourceforge.net/projects/mdbtools) that allows you to extract
tables on your unix box. However although you won't need Access, you'll
still have to write something to slurp in a text file afterwards.

Hello all,
I need some advice on Universe and .NET. We would like to begin using
.NET as our front-end with Universe as our back-end. We have started to
explore UO.NET, but it does not seem to provide us with the performance
we will require. Our processes are currently written in PICK BASIC
You do have to disallow modification of the print string by the database or
spooler. I use 'SETPTR ':lpu:',1024,80,,,1,NFMT,dest printer,BRIEF', where
lpu is the logical print unit. The no format seems to work. I've seen other
suggestions on this list for accomplishing the same. I get errors
Hi,
I would like to do some encryption of data in a Unidata file. I wonder if
there is someone who has a MD5 hashing unibasic subroutine that I could use.

Hi All,
We are planning to train some of our new programmers
to use good programming practices when using U2 Basic.
I can remember in Unidata days us having some tech
support documents that talked about this. Example such
as when is the best time to use CASE instead IF ELSE
or not to use GOTO
The reason that our current processes are so fast is that we read as
much common data as humanly possible into memory at start-up so there is
little overhead while the process is running. If I have to call a
subroutine from .NET, that would actually slow processing down. I need
to get the data

is there a udt.option that allows you to use lower case in unidata

thanks ..
My addition to this would be to use alphanumeric labels, and to *have* a
main calling section. A main calling section that looks like:

GOSUB SELECT.FILE
GOSUB PRE-PROCESS.VALIDITY.CHECKS
GOSUB PRINT.INVOICES
GOSUB UPDATE.FILES

I prefer alphanumeric labels for subroutines. The label should give some

Since the RETURN statement actually has 2 meanings, I add a comment at the

We do something similar, have a look at COM+ object pooling (google/msdn).

for a set period of time, the sessions will close.
