title: SAS proc import .csv files missing column issue
body: <p>I am trying to import multiple .csv files into SAS. Those csv files are 12 months' hourly temperature data each column represent date and time. For instance, column for January file is: 20120101 00-20120131 23. Since the length of month differs the column numbers differ accordingly. </p>
  
  <p>Using following codes to import data,</p>
  
  <pre><code> proc import out=air.air&amp;year
   datafile="year\hourly*.csv" dbms=csv replace;
   getnames=yes;
   DATAROW=2; 
   run;
  </code></pre>
  
  <p>I only got date time up to day 29. I guess the reading sequence matters so I tried to reorder the file name to make the January the first file but still failed to read in all columns. </p>
  
  <p>It's not easy to specific the files names one by one given about 20 years monthly hourly data involved. Does anyone know in which order SAS reads files within one folder?</p>
  
  <p>Really appreciated if someone could point me one direction of dealing similar task appreciated.</p>
  
  <p>Thanks!</p>
