title: Is it possible to loop over SAS datasets?
body: <p>I have 60 sas datasets that contain data on consumers individual characteristics such as  <code>id, gender, age, amountSpent, ....</code> Each dataset shows data only for one time period (data1 is Jan, data2 is Feb...). I cannot merge them because of the size and some other issues.</p>
  
  <p>How can I write a multiple loop to go through each of the datasets, do some manipulations and save the estimated values to a temporary file.</p>
  
  <p>SAS does not have a <code>for</code> loop. How can I use <code>do</code>?</p>
