Countdown
Description
Author: Eddie Shore, November 2011
Make a program that has the calculator count down from N to 1.
Instructions:
1. Enter N.
2. Press [ f ] [ e^x ] (B) to run label B.
Note: The calculator is set to integer mode (Fix 0). You may need to change the mode back after using this program.
If you own a HP 15C Limited Edition: Replace PSE with R/S, because the pause does not work (unfortunately).
