That line just means 'create a variable called "A" inside a group called
"mygroup", and assign it a value of rand(2)'. If you don't need that variable,
you don't need that line. You also don't have to create a group called
"mygroup", if you prefer you can store everything in the top level of the file.

Not sure. It works for me (Kubuntu Linux 14.04).
