title: PROGRESS - Validating a user-input file output path
body: <p>I've written some PROGRESS code that outputs some data to a user defined file. The data itself isn't important, the output process works fine. It's basically </p>
  
  <p>DEFINE VARIABLE filePath.
  UPDATE filePath /*User types in something like C:\UserAccount\New.txt */
  OUTPUT TO (VALUE) filePath.</p>
  
  <p>Which works fine, a txt file is created in the input directory. My question is:</p>
  
  <p>Does progress have any functionality that would allow me to check if an input
  file path is valid? (Specifically, if the user has input a valid directory, and if they have permission to create a file in the directory they've chosen) </p>
  
  <p>Any input or feedback would be appreciated.</p>
