title: windows batch file: calling executable in another directory
body: <p>This seems like something simple, but I don't seem to be able to get it.
  I have a directory called "test" with an executable hello.exe that basically prints "hello" onto the screen.</p>
  
  <p>I want to execute this program from the current directory using relative paths.
  So I write</p>
  
  <pre>
  test\hello.exe
  </pre>
  
  <p>Thinking it would execute the program "hello.exe" located in directory "test". But it doesn't. Am I missing something?</p>
