== Why is this an issue?

``++GoTo++`` is an unstructured control flow statement. It makes code less readable and maintainable. Structured control flow statements such as ``++If++``, ``++For++``, ``++While++``,  or ``++Exit++`` should be used instead.

=== Noncompliant code example

[source,vbnet]
----
    Sub GoToStatementDemo()
        Dim number As Integer = 1
        Dim sampleString As String
        ' Evaluate number and branch to appropriate label.
        If number = 1 Then GoTo Line1 Else GoTo Line2
Line1:
        sampleString = "Number equals 1"
        GoTo LastLine
Line2:
        ' The following statement never gets executed because number = 1.
        sampleString = "Number equals 2"
LastLine:
        ' Write "Number equals 1" in the Debug window.
        Debug.WriteLine(sampleString)
    End Sub
