The "_Variable" Command

[RunAwayScientist]

         This may be more of a scripting question ,
 but, I'm sure you guys can handle it. Right?

         I've seen  this in scripts, and I've seen it when I downloaded the Chinhook with a Cargo Hook. Yet, I don't know the proper way to use it. It's, the Under-Slash Variable command *dun dun dun*. For example:

    _Mommy doFire _Daddy

     Instead of:

        Brother doFire LittleBrother

        I've seen it in this command: "_x moveinDriver Ccar2" Foreachunits Police . What I'm thinking is that the _x is some variable, errr, like Algebra. Except, when putting these into a script, the item that triggers that script I usually see two Bracets, in which were used to define the variables.

  For Example:

[ Ccar2, Police] exec "MoveinDriver.sqs"

       So, how do I use this Command? The Underslash? Will it make scripting easier? How do I define the variables? The world may never know....
