title: Creating a series of numbers in Red language
body: <p>I have a few simple questions, hence I am putting them together: </p>
  
  <ol>
  <li><p>What is the best way to create a series of numbers. Following works but is there a simpler method like 1:10 available in some languages?</p>
  
  <p><code>myseries: []</code></p>
  
  <p><code>repeat i 10 [append myseries i]</code></p>
  
  <p><code>print myseries</code></p></li>
  </ol>
  
  <p>(1a. Why is above code not making usual code block on this page?)</p>
  
  <ol start="2">
  <li><p>Similarly, what is the best way to create a series of 10 elements,  all initialized to 0 or ""? Do I have to use there also <code>repeat i 10</code> or <code>loop 10</code> and serially <code>append</code> an initially blank series?</p></li>
  <li><p>Also, should I specify the number of elements as in following code while creating the series initially? What is the disadvantage of not doing this?</p>
  
  <p>myseries: make block! 10</p></li>
  </ol>
  
  <p>Thanks for your help.</p>
