title: Use Keywords in variable section- Robot framework
body: <p>i am trying to create a variable in the variables section but by appreciating it i am doing something wrong.</p>
  
  <p>so I have it now and it works.</p>
  
  <pre><code>*** Variables ***
  
  
  *** Test Cases ***
  MyTest
      ${DATA}=     read_csv_file     ../data.csv
      Log     ${DATA}
  </code></pre>
  
  <p>read_csv_file is a keyword that i design.</p>
  
  <p>I would like it to work like this.
  but the log only shows "read_csv_file ../data.csv"</p>
  
  <pre><code>*** Variables ***
  ${DATA}=     read_csv_file     ../data.csv
  
  *** Test Cases ***
  MyTest
      Log     ${DATA}
  </code></pre>
