Read a text from the terminal and print it back in capital letters.

This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on.

The steps

  1. We add a While loop, which repeats forever.
  2. We create a text variable called terminal.
  3. We create another text variable called reading.
  4. Above the loop we clear the terminal with an empty Set.
  5. Behind it we read what is typed into reading, using Wait.
  6. Behind it we add a Join block.
  7. Inside the Join we put To uppercase.
  8. And we give it the variable reading.
  9. On the dashboard we draw a terminal and give it the variable terminal.

When you finish, the app takes you straight to the next tutorial in the path.
