Object Reference passed by value or by reference

[bienieck]

Is there a difference when passing object reference parameter by reference or by value? It seems to me that the behavior is the same.

Since you are not changing the reference itself, there is no difference IMHO

But what if it is a connection refnum and I do the reconnection with a new refnum in place?

This should make the old ref invalid thus ByRef would be required IMHO. Yet.... If I understand you correctly, it didn't matter in your case, right?

Maybe your reconnect reuses the refnum?

Yet this is highly speculative from my side
