How to GET OUT of a HOOK?

[timetunnel]

Hello.

Is there a condition that can be set WITHIN THE HOOK to GET OUT of that HOOK at a moment's notice (under a certain condition)?

If so, what is that condition syntax ?

Thanks in advance.

EDIT: I re-evaluated hooks - it doesn't appear that you get in/out of them like you would a function. It seems it is just a placeholder for additional code. The code itself must determine how to move on to the line following the hook.
