I am running latest toolkit. My ESQL is using several topic names that I would like to be configured at deploy time.
I defined a UDP group at the flow level with a UDP property but cannot find any documentation at all on how to access these properties via ESQL.
I also tried defining a variable using EXTERNAL keyword but it does not show up in bar editor.
Any help from someone who's got this working is greately appreciated.

To change UDP in bar you should promote UDP property.

I defined a module for my compute node like this.
DECLARE udp1 EXTERNAL CHARACTER;
CREATE COMPUTE MODULE SingleViewPublisher_Compute
DECLARE udp2 EXTERNAL CHARACTER;
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
-- CALL CopyMessageHeaders();
CALL CopyEntireMessage();
DECLARE udp3 EXTERNAL CHARACTER;
................
ie. In three different palces and still when I right click on the compute node, neither udp1, 2 or 3 are the in list of properties which could be promoted.

They won't be promotable.
You can't declare them inside the function, so your upd3 is not valid, I believe.
And, again, you have to define them on the Flow as well.
And they won't be properties of any particular NODE, they are properties that are set on the whole flow. So in your BAR file, after making sure you have refreshed the contents, go to the Configure tab, and select the Flow itself, and not any of the individual nodes under it.

You to need to follow 3 steps for setting the UDP Properties
1)Go to the MessageFlow window go to the user defined properties and there you can see the Properties there Rightclick on the Basic and add the Property to it .
2)In the ESQL ,with whatever the name you created the property in the messageflow editor delcare that as
DECLARE udp1 EXTERNAL CHARACTER;
3)On the bar File you need to go to the configure tab and set the value for UDP .
