title: SAS: How to prevent "WARNING: Apparent invocation of macro not resolved" within a libname statement?
body: <p>I have to use a password similar to the password below within a LIBNAME statement. The password includes a percentage sign (%) which results in the WARNING: Apparent invocation of macro PS not resolved:</p>
  
  <pre><code>LIBNAME EXAMPLE ORACLE
  user=user1
  password="'thisisapassword%PS|("
  PATH=PATH1
  SCHEMA=SCHEMA1
  ;
  </code></pre>
  
  <p>Because the password already includes a single quote, I have to use double quotes for the password, eventually resulting in a warning due to the percentage sign being used</p>
  
  <p>I can't find how to escape this % or any other way to prevent this warning from occuring</p>
