UE take care of the execution flow in blueprints by how nodes are connected through their EXEC ports. What does EXEC stand for? Is it EXECUTABLE or EXECUTION? Is it stated somewhere in the documentation?

This question stroke me out of curiosity, so please bear with me.

It’s an execution pin, I believe I I’ve seen the name referenced somewhere in documentation…
