I would suggest for this case that at the end of each
quarter, you end the survey, copy it, and activate the new
copy. If you are doing data analysis in a separate program,
then you should have no problem appending one quarters data
to the rest. This way you would have multiple surveys named
something like:
  quarterly_survey_q1_02
  quarterly_survey_q2_02
  quarterly_survey_q3_02
  quarterly_survey_q4_02
  quarterly_survey_q1_03
  ...

However, it may still be a good idea to not overwrite
existing data files. Perhaps a confirmation screen, or a
screen with a box to enter an alternate filename, would be
a nice feature.
