Hello list,

I am working with messages to create objects inside a patch, I think I have solved
the creation of the objects, but I don't know how to connect them.
When I create an object, its "number" depends on the objects created before, and
the order of creation, how can I know what is the number of a certain object?

With number I mean the fields A and B in the message  [connect A X B Y( , I already
know what A, B, X and Y are, but I don't know how to know A and B, for the objects
I want to connect.

Do you know what other things can I modify in a patch through messages?

Thanks,

Ricardo D.
