This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Microsoft Excel does not have a "Macro Paused" Toolbar that can be invoked by a single command. This is true even when you run an MS Excel 4.0 macro.

The following Visual Basic code comprises two sub procedures that you can modify to create the effect of pausing a macro.

If you have a single procedure within which you need to pause execution until the user desires to resume execution, split your sub procedure into two halves. On the last line of the first half of the sub procedure, call the "First_Half" sub procedure. Within the "Second_Half" sub procedure, substitute the name of the sub procedure that is the second half of your original sub procedure on the line where the MsgBox is currently located.

   ' This Sub procedure should be called on the last line of your original 
   ' Sub procedure.
   Sub First_Half()

      ' Create a toolbar.
      Toolbars.Add "resume"
      
      ' Add the button to the toolbar.
      ' Note that if you are using Microsoft Excel version 5.0,
      ' comment out the "StatusBar:" argument of the Add method and remove
      ' the comma and line-continuation character after "Enabled:=True"
      Toolbars("resume").ToolbarButtons.Add Button:=102, _
         OnAction:="Second_Half", Pushed:=False, Enabled:=True, _
         StatusBar:="Click here to resume macro"
   
      ' Name the button.
      Toolbars("resume").ToolbarButtons(1).Name = "Resume Macro"

      ' Make sure the bar is not docked.
      Toolbars("resume").Position = xlFloating

      ' Position the bar midway between the left and right of the window.
      Toolbars("resume").Left =  _
         (ActiveWindow.Width + Toolbars("resume").Width)/ 2

      ' Position the bar midway between the top and bottom of the window.
      Toolbars("resume").Top =  _
         (ActiveWindow.Height + Toolbars("resume").height)/ 2

      ' Make sure the bar is showing.
      Toolbars("resume").Visible = True

   End Sub

   Sub Second_Half()
  
      ' Delete the toolbar.
      Toolbars("resume").Delete

      ' Insert the name of the second half of your procedure in place of 
      ' this message box.
      '
      ' NOTE: Any variables dimensioned in the first half of your
      ' procedure may lose their values before this sub procedure is       
      ' executed. You will need to be certain any variables used by the 
      ' procedure you name in place of this message box are dimensioned at 
      ' the Module level.
      MsgBox "after"

   End Sub
