電腦硬體可不斷循環運動，例如汽車旋轉車輪前行，但是要指揮左右轉彎，加個軚盤，要有指令（左邊拐彎，再直行百米右邊拐彎，再停下來再後退三米，）電腦程式設計也就是指令，命令不斷循環運動中的機器，如何達到泊車位目的。
電腦程式設計：CarParking
Public Class Form1
Dim number As Integer = 0
Dim sampleString As String
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
' Evaluate number and branch to appropriate label.
If number = 100 Then GoTo LastLine Else GoTo Line2
Line1:
sampleString = "Number equals 100"
TextBox1.Text = sampleString
Line2:
' The following statement never gets executed because number under = 100.
number = number + 10
sampleString = "Number equals " & number.ToString & " M"
TextBox1.Text = sampleString
Exit Sub
LastLine:
Beep()
End Sub
End Class
