Drawing to the screen is very useful. I used it last year:
If you are using PROS, here is the documentation for setting text to a screen:

* With PROS, you have to delay between each command by 50ms. If you don’t, the commands you send will not be forwarded to the controller, which only updates every 50ms.
I believe VEXCode automatically inserts those delays in the controller commands for you.
