-|text= Example 2 is very handy for checking if a given control is [[controlNull]] without using negation.<br>
-Here is a practical example of that:<br>
-<sqf>[ controlNull ] call {
-    if( ctrlIDC( _this select 0 ) > -1 ) then { systemChat "the control exists!" }
-}</sqf>
-'''however, keep in mind that most controls have <syntaxhighlight lang="cpp" inline>idc = -1;</syntaxhighlight> by default.''' But that is easy to change :)<br>
-The method shown above works great for functions where a control or controlNull could get passed into.<br>If the function should only do something if the control exists, then that method is a great way to handle that while avoiding negation.
