Can a variable change? Also, can stages broadcast?
what do you mean by a variable changing? change name? change value? in what situation?
it seems really easy to check if a stage can broadcast, i'm not sure if you're trying to ask something else.
this is as tautology as "do potentiometer have various resistances"
please be helpful, not rude. pointing at jargon doesn't make people understand it.
I mean that variables of course change
