SYMPTOMS

In Microsoft Excel, when you run a Visual Basic Sub procedure that calls another procedure, you may receive the following error message:

   Run-time error '28':
   Out of stack space

CAUSE

This error message appears when one procedure in your module calls another procedure, and that procedure calls another procedure, and so on. The error message occurs in this case because when you call one

sub procedure from another procedure, the first procedure is not

unloaded from memory until the procedure that it called is finished. Because of this behavior, if you continue to call a procedure from another procedure, you may run out of stack space, or memory allotted for the macro, before the last procedure is called.

WORKAROUND

To work around this problem, call individual sub procedures from one main procedure, instead of calling one sub procedure from another sub procedure, and so on. For example, if you are calling sub procedures as in the following example

   Sub one()
      two
   End Sub

   Sub two()
      three
   End Sub

   Sub three()
      four
   End Sub

you can call these sub procedures from the first procedure as in the following example:

   Sub Main()
      one
      two
      three
      four
   End Sub

MORE INFORMATION

The Visual Basic Reference indicates that the "Out of stack space" error may be caused by too many active Function or Sub calls. To correct this problem, Help suggests that you verify that general recursive procedures are not nested too deeply and that they terminate properly.
