SYMPTOMS
When you run a Microsoft Excel Visual Basic for Applications subroutine you receive the following error:

Run Time Error 28: Out of Stack Space



CAUSE
The error message appears if both of the following conditions are true:


 * You call the same Visual Basic for Applications subroutine that you are running from within itself (recursively).

-and-


 * The subroutine call is designed to run over and over again from within a loop.



WORKAROUND
To work around this behavior, use a GoTo statement in your code to branch to a previous line label instead of calling the name of the subroutine itself.

Sample Code
The following sample code generates the error message described in the &quot;Symptoms&quot; section: Global y Sub test1 For x = 1 To 100 y = y + 1 If y > 100000 Then MsgBox y           End End If       test1 'Starts loop over again by calling the macro by name Next x ' Code never gets this far End Sub To correct this code, add a label to the subroutine and add the GoTo statement as shown in the following example: Sub test2 Marker: For x = 1 To 100 y = y + 1 If y > 100000 Then MsgBox y           End End If       GoTo Marker 'Starts loop over at the line labeled Marker Next x ' Code never gets this far End Sub
