Re: DDS Support -- MIDRANGE-L

Hi, I will like to add my 0.02 cents.

One of the main things that I like about the AS/400 is his "openness" in
development.  Before any flames start on me about this "openness" let me
explain.

AS/400 is one of the machines who let me develop any way a want according to
my necessities and comfort.  If I develop communications I have sna, tcpip,
ipx, etc.   I can use remote dataq, icf, sockets, ddm, etc.  I can go over
sdlc, async, ethernet, fast Ethernet, token ring, fddi, etc.

If it is application development (actually a didn't like the name change
from application system to advanced server), I have Java, RPG, Cobol, perle,
rexx, Pascal, c, etc.  If a want client server I have any ODBC applications,
visual rpg, visual basic, Smalltalk, SQL, etc.  And is not only that, I can
develop with a combination of all this environments  without any major
problem.  Try to access an Oracle data base from an legacy COBOL application
or viceversa.

At the end, I don't think SQL should replace DDS or the other way around.  I
love that Rochester let me choose the way a will like to go.  I think taking
out one of them it will like Rochester deciding if they will take out DOU
for DOW or viceversa.

Sorry about the translation.

Emilio
