title: How to put spaces in variable names?
body: <p>I want to learn how to add spaces in variable names.</p>
  
  <p>I know that a lot languages prevent me from doing this, but I believe that there is a trick to do this because I saw someone did it in <strong><code>MQL5</code></strong></p>
  
  <p>A <kbd>MetaTrader Terminal</kbd> allows to show a UI-Dialogue Panel for MMI-assisted setting values for <code>input</code> and <code>extern</code> variables declared in { <code>Expert Advisor</code> | <code>Technical Indicator</code> | <code>Script</code> } code, during a code-execution launch. </p>
