title: How to execute FreePascal from windows command line as "fpc"
body: <p>I've noticed at one place that they was able to call FreePascal compiler as "fpc" from windows command line like:</p>
  
  <pre><code>fpc my_program_source.pas
  </code></pre>
  
  <p>How to achieve this? Is it some command that assigns "command => exeFile" ?</p>
  
  <p>Thanks.</p>
