[this,(getpos this)] exec "height.sqs"
Now you should be able to refer to the object in your script like:
_object = _this select 0
_objpos = _this select 1
_height = **WHATEVER HEIGHT YOU WANT**
_object setpos [(_objpos select 0),(_objpos select 1),(_objpos select 2) + _height]
Sorry i can't try it out for myself right now to ensure it (i'm at work
) but it should work.
