I am going to try to code a program that does the following (when run):
turn the screen black(graph with black background, whatever)

makes white text (in middle of screen) appear saying "Hey!"

I am using a ti-84 plus CE. Could you help me code this simple program?
Turn the screen black:

This one's easy. For the graphscreen, use BackgroundOn(BLACK).

Make white text:

More difficult. For "large"-size text, you can set TextColor(WHITE) and then display using Text([y position],[x position],"Hey!". However, that would make the text display on a gray block. You'll need to use either text sprites or library sprites to get a black background or display test larger than the "large" font.
