MailMerge and VBA

Hi All,

When I prepare a MailMerge in Word97 and record a macro
during such preparing I can get a VBA code in the Visual
Basic Editor for the whole preparation. Then I can save
it as a .bas file.
The question is : if I have already done MailMerge files
(with << ... >>), is there any method to get the VBA code
automatically, i.e. without repeating the process of
recording a macro?
I can use a newer version of MS Word.

Please tell me how to do it if you know.

Regards
User
