batch measurements to single data file

I have put together a simple macro to (batch) perform various
manipulations and then measure particle diameters for a series of
several hundred images of liquid droplets.  Everything works fine,
except for each image that runs, the results window discards the data
from the previous image.

I'm sure there is a simple way to change that, but I've been searching
the documentation and mailing list archives all morning and haven't been
able to find anything useful.  Is there a simple way to have the data
from previous measurements preserved when a new image is opened and
processed?  Alternatively, is there a way I can have the results dumped
to a data file (but a single data file for all the data with each
measurement on a new line?).  I tried having a save as command as part
of my macro, but it kept trying to over-write the data file on each
iteration.

I have attached my macro.

Thanks;
