[RMVX] Obtain array name class

I need a way to get the array of class names to be used later as a command ...
The code used by me would be this:

Code: [Select]

    command = []
    for ??? in ???
    comman.push(???)
    end
    @command_window = Window_Command.new(300, command, ... ... etc

(obviously not in the script I put '' xD)

Thanks for any replies

EDIT:
I also wrong section
