I am trying to make my graphing calculator display Hello, World! on the screen. How do I do this (I want to program a program to do this, as typing alpha, letter is inefficient)?
Use the Text( command in the draw menu.
Where X and Y are your locations:
Text(X, Y, "HELLO, WORLD")
According to catalog:
Text(row, column, text1, text2, ..., text n)
On color calculators the text color can be changed with the TextColor( command.
