Nodes with internal variables and "context"

Yeah.

Thanks.

Ok. So with that knowledge I shall have to do some thinking.

So, going on what you said, I have to start NR from the CLI/Terminal and run it as:
node-red --inspect yeah?

I guess I could also go to the other end and just stick debug nodes on the output of said nodes and log their output.

Looking at/in the debug node there is the system console option. But info doesn't really elaborate on that.
If I have 3 nodes doing that I'm guessing I need 3 system consoles open?

I'll maybe play with that now for a while and get a feel of how it works.
But if you could help confirm my thoughts; it would be appreciated.

I just tried that and have an inject node connected to a debug node and ticked the system console option ticked.

I press the inject and....... I see the output at the right of the screen, but system console.....

Where is it?
