After some research I found out, that you can access the parents flows variables in a subflow by using environmental variables in the subflow. Is that also possible for global variables?  
Background:  
I want to implement an alarms-system. These alarms can be triggered in different flows, so I save the alarm states for each alarm globally in an array.  
Why the sublow?- Wanted to make the flow look cleaner- no technical background.

I just tested by setting a global var in a function node that **is not in a subflow** and was able to successfully access it from another function node that **is in a subflow**. It seems that `global.set` and `global.get` are not limited by being in a subflow.

I guess I was overthinking the topic, should´ve tested first before posting 😅
