Beginning with Word 97, Visual Basic for Applications has replaced WordBasic as the Word for Windows macro language.

There can be many causes for an infinite loop. For, example an infinite loop will occur if you create a loop to check the value of a variable that never changes, as in the following example:
   Sub InfiniteLoop()
      Dim n As Integer
      n = 0
      Msgbox ("WARNING: This macro will cause an infinite loop. Press" & _
      CTRL+BREAK to exit an infinite loop.")
      Do
      ' Because the "Do...Loop" is looking for the value of 'n'
      ' to equal 1, and because there is no code within the loop
      ' to change the value of the variable 'n' from it's initial
      ' value of zero, the "Do...Loop" will continue to loop indefinitely.
      Loop Until n = 1
   End Sub
