How to get & run programs on TI-84 Plus:
Contact Linda to find out how to get the programs loaded onto your calculator.
To run a program: Press PRGM and choose the program (ex. LINES) by scrolling and pressing ENTER or by typing the line number. You will see "prgmLINES" on the main screen. Press ENTER once more to run the program.
A program is finished when you see 'Done'. You may type calculations as usual on the next line. Some programs wait until you press ENTER before saying 'Done'. This allows you to see the program results / answers before they scroll off the screen.
To end a program while it is running: For some programs, press 2nd-QUIT (on the MODE button). For others, press ON, and choose QUIT. If all else fails, turn the calculator off and on again.
