In versions of Word prior to Word 97, the WordBasic macro language allowed you to
break out of macro execution using the ESC key. 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
