title: Display info message on INITIALIZATION
body: <p>I want the user to notice that the report he's currently using is deprecated and replaced by another one. Therefore I'll need to have a popup like an info message on program start.</p>
  
  <p>But when I try to run my code like this:</p>
  
  <pre><code>INITIALIZATION.
      MESSAGE i355(zz).
  </code></pre>
  
  <p>The message only appears in the status bar. </p>
  
  <p>This approach would look okay from user side:</p>
  
  <pre><code>INITIALIZATION.
      DATA: w_mes TYPE string.
      MESSAGE i355(zz) INTO w_mes.
      CALL FUNCTION 'POPUP_TO_DISPLAY_TEXT'
        EXPORTING
          textline1 = w_mes.
  </code></pre>
  
  <p>But in fact it's very messy. </p>
  
  <p>Is there a smoother way to display an info message on program start?</p>
