At this point, it is good practice to run the application to make sure that the database is set up correctly and the application is running properly. It should work just like the solution from the previous chapter.

Each command usually has help built in, which you can query (a little like typing / after a command when using DOS). This will explain what the command does and how it should be used. In most cases, you ll see an example of the command in use, along with the range of command options that can be used with it. For example, you can get some instant help on the ifconfig command by typing this:

public function playTrack(songUrl:String, songLength:Number=0):void { // needs to implement }

attempt to do this using System.Threading.Thread.Abort(), but using this method may have many unintended consequences, discussed later in this chapter.
