2. Scrolling Text Window Define a text window that is approximately three fourths of the size of the video display. Let the program carry out the following actions, in sequence:

• Draw a string of random characters on the top line of the window. (You can call Random_range from the Irvine16 library.)

• Scroll the window down one line.

• Pause the program for approximately 200 milliseconds. (You can call the Delay function from the Irvine16 library.)

• Draw another line of random text.

• Continue scrolling and drawing until 50 lines have been displayed.
