command is unknown to the Editor/or just wrong Syntax?

I noticed the ingame mission editor does not know this command. When I try to type it for the first time no auto completion appears. And when I used either of the example syntax I get an error message. (Missing ";"). I tried to execute it from trigger, waypoints and from an sqf script. I always get the same error. I kinda suspect the game doesn't know about this command. Or does it need a different syntax that I didn't figure out?
