create new variable when combining datasets

podarum — Mon, 12 May 2014 15:05:05 GMT

Hi, I have 7 datasets that I must combine (simple data & set statement), but I want to create a new field called cohort that specifies a different value from each dataset. So in dataset1 I want cohort to = '2007', and dataset2 to have cohort = '2008' .. and so on.. So in the end 1 large dataset comprised of these 7 sets and i new variableCohort with 2007, 2008, 2009, 2010, 2011, 2012, 2013 . Thanks
