' Example for the Environment.Exit( Integer ) method.
Imports System

        Dim args As String() = Environment.GetCommandLineArgs()
          
        ' args[0] is the program name, and args[1] is the first argument.
        ' Test for a command-line argument.
        If args.Length > 1 Then

            ' Parse the argument. If successful, exit with the parsed code.
            Try
                Dim exitCode As Integer = Integer.Parse(args(1))
