title: Proc append and addressing excel sheets
body: <p>I'm using this code to update an Excel sheet:</p>
  
  <pre><code>libname xls excel '..\append.xls' ver=2002;
  
  proc datasets lib = xls nolist;
  delete output;
  quit;
  
  data xls.output;
  set Ongoing_SE;
  run;
  libname xls clear; 
  </code></pre>
  
  <p>The above part creates the output file.</p>
  
  <pre><code>libname xls excel '..\append.xls' scan_text = no ver=2002 ;
  
  proc append  
  base = xls.output
  data = Ongoing_SE;
  run;
  libname xls clear;
  </code></pre>
  
  <p>I want to append data into specific sheets of the excel file but I don't know how to address excel sheets.</p>
