Hm. With kronzkys UPS its a bit difficult : if Im not mistaken it duplicates itself: i.e., even though you grab a handle using ScriptHandle = [parameters] execvm "ups.sqf", scriptHandle will only correspond to ONE instance of the script. I might be wrong however!
As it were, youre in luck: UPS has a lot of built-in features that you would do well to use. Open up the script in notepad and read the script heading for all kinds of advanced usage, including, I believe, a way to disable zones and turn off a lot of stuff. Check it out.
Otherwise, you can always try to use the
terminate command on the script handle and try to turn it off that way
Wolfrug out.
