How do I see the value of variables?

[PotatoChild2]

I know this is a pretty simple question, but I'm stumped. If I have a variable named "Queue", then how would I be able to see the value of Queue while in play mode?

The command "/plots vars" sends a list of vars, but you can narrow it down by adding the variable name as an argument.
ie. "/plot vars queue".

Otherwise, use send message.
