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
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
Compliant solution
Sub gotoStatementDemo()
Dim number As Integer = 1
Dim sampleString As String
' Evaluate number and branch to appropriate label.
If number = 1 Then
sampleString = "Number equals 1"
Else
sampleString = "Number equals 2"
End If
Debug.WriteLine(sampleString)
End Sub
Exceptions
On Error GoTo statements are ignored as correct error handling.
