Thank you for the informative reply.  I have done a lot of VBA in Excel and
if this was Excel I'm sure I could do it - but I am just starting with VBA
for Publisher...

What is an external widget and what languages support COM or COM Interop.  
Is that a seperate language "outside" of VBA that I would then use to access
the "guts" of Publisher without actully starting publisher?  If so that might
be the way to go.  I had read the articals in the links from the previous
post and wrote a macro that would run everytime the file was opened, it would
then close the MailMerge, re-open the Mailmerge pointing to the new datafile
(tried to have it use a CSV file but found out it likes Tab separated files
better) - then it appended to a blank publisher file.  Thsi seemed to work ok
- but it chocked on larger mail-merges.  So if there was a way to do this a
different way it might run better.  Also, I have several Publisher files that
I need to perform a merge on each night so if an external widget would allow
me to go from one file to the next that woudl be great - I haven't figured
out how to do that yet in VBA for Publisher.

Here's the general idea of the code I have so far
Sub Document_Open()
DIM Temp as Document

ActiveDocument.MailMerge.Datasource.Close
Active Document.MailMerge.OpenDataSource ("Filename")
Set Temp = ActiveDocument.MailMerge.execute(False,
PBMergeToExistingPublication, "filename"

End Sub

Any help will be greatly appreciated.
