SETUP LEVEL Filter
Syntax: SETUP LEVEL { VIEW | * | level [ {, level | - level} ]... }
Filters elements based on their level.
SETUP LEVEL VIEW filters out only elements on a level that are turned on in the selected view.
SETUP LEVEL * allows all elements to be handled.
Specify one or more levels directly. Legal values for the level number is 1-63. Use variables containing the level values.
Specify one or several levels separated by a comma, for example, SETUP LEVEL 10,20,30.
It is also possible to specify a range of levels using a minus sign (-), for example, SETUP LEVEL 1-10,30-40.
If no SETUP LEVEL filter is specified, all levels are used.
