In the world of programming, particularly when I’m tinkering with Microsoft Excel using Visual Basic for Applications (VBA), control structures are fundamental. They are like the traffic signals of my code, dictating the flow and order of operations. I recently came across the VBA GoTo statement, a tool that’s as straightforward as it gets. With GoTo, I can direct the execution of my program to jump to any specific line of code within a subroutine. It’s like having a teleporter at my fingertips, although I need to be cautious with its use to avoid creating a tangled mess commonly known as spaghetti code.

As a programmer, I find that the GoTo statement can be quite handy in certain scenarios, for instance, when I need to quickly exit out of deeply nested loops or when handling errors in a specific way. It’s part of the larger family of control structures in VBA that govern how my program executes, which also includes loops, conditionals, and other statements. Although it’s powerful, I remind myself to use GoTo judiciously in my VBA editor within the Excel environment, as it can make my code harder to read and maintain if overused. Control structures like If…Then…Else or Select Case tend to offer more clarity, but there’s no denying GoTo has its place in my VBA toolbox for its simplicity and directness.

How to use VBA GoTo Statement in a Code

When I write VBA code, sometimes I use the GoTo statement to jump to specific sections of the script. It’s straightforward:

  • To initiate a jump, I write GoTo followed by a label name.
  • I then define the target by creating a label, marking the destination.
  • I tag this spot in the procedure, making it a receiving end for the GoTo.
  • Finally, I ensure the relevant code follows the tag for execution upon arrival.

For clarity, here’s how it looks:

Sub vba_goto()
    GoTo Last
    Range("A1").Select
Last:
    Range("A12").Select
End Sub

The GoTo statement can only branch to labels within the same procedure, and it’s best not to overdo it to keep my code clean!

GoTo to Repeat a Code

When I write macros in Excel VBA, one tactic for handling repeated actions based on a user’s input is using the GoTo statement. Here’s a brief breakdown of how it operates within a macro:

  • Initiate InputBox: Prompt the user.
    Example: iMessage = InputBox("what's the day today?")
  • Evaluate Condition:
    • If the condition is met (i.e., the answer is “Tuesday”), a MsgBox confirms the correct answer.
    • If not, a MsgBox alerts the user of the wrong answer.
Sub goto_repeat()
    Dim iMessage As String
    Question: iMessage = InputBox("what's the day today?")
    If iMessage <> "tuesday" Then
        MsgBox ("wrong answer, try again.")
        GoTo Question
    Else
        MsgBox ("that's the right answer.")
    End If
End Sub

Key Points:

  • Use GoTo Carefully: It can inadvertently create an endless loop if not handled correctly.
  • MsgBox Functionality: Handy for feedback and simple interactions within a worksheet.
  • Loops & Conditions: GoTo isn’t the only way to repeat code; loops can often serve a similar function with more control.

Remember, the GoTo statement can get me where I need, but it’s like using a scroll with no end—it keeps unrolling unless I tell it when to stop. It’s crucial to always have a proper exit condition to prevent endless repetition that can bring the workbook to a standstill.

VBA GoTo End

Sub ExampleSub()

    ' Some code here...

    On Error GoTo ErrorHandler
    ' Code that might cause an error

    ' More code...

    Exit Sub

ErrorHandler:
    ' Error handling code.
    Resume Next
End Sub

In VBA, the GoTo statement can divert the flow to an error handler or exit a subroutine early:

  • On Error GoTo ErrorHandler: Redirects to a labeled error handler.

  • Exit Sub: Terminates the subroutine.

  • ErrorHandler: A label for managing errors.

  • Resume Next: After handling an error, continues with the next line of code.

GoTo Statement to go to a Line in Another Sub Routine

  • GoTo: I use this to jump within my current procedure.
  • Limitation: Can’t leap to labels in another procedure.
  • Reference: Utilize Call or Application.Goto method for cross-subroutine actions.
  • Save Point: No, GoTo won’t save your place before a jump.
  • Subroutine: For a clean switch, I prefer modular calls.
  • Remarks: Overuse may clutter the code; I keep it minimal.
