Kent,

Just getting back to this - Mondays are always hectic.  This recipe is the
one I saw and like.  It looks cool!  In my brief efforts tinkering with it,
I am not really getting very far.  I saved the recipe, and import it into
the file containing all my database functions.  In one of the
functions, I have the following:

I used the "from tbl_Tabs import *" approach to import the recipe.  If I
should be doing this differently, just say so.

    for record in Results:
        print '%-15s\t%-15s\t%-15s' % record    
# I still want to print to screen, then...

        mbrPhone = open('mbrPhone.txt', 'w')
        mbrPhone.write(indent(record, hasHeader=False, separateRows=True))
        mbrPhone.close()

I first assumed that "record", and then "Results" could be substituted for
"rows", per the recipe.  I also tried "rows", and assigning "record", and
then "Results" to "rows".  O.k., you can laugh all you want.  I tried
playing with the various arguments, and found that to be of little value.

The traceback refers to a type error: iteration over a non-sequence.  The
query returns a tuple, as I understand it.  I also understand a tuple to be
a sequence.  If this is really as simple as the 3 lines you pointed out
above, I know I'm missing something in the implementation.
