Program: prgmPOSTAL
Author: David Tolnay

This program is pretty easy to use. Run the program. It will prompt you for a 10-digit postal code. If you don't know what the check digit is, it is fine to type just 9 digits instead of 10. Press enter. A postal code will be displayed on the screen. Since the screen of the TI-83 Plus isn't wide enough to display the whole thing through, I had to cut out the spaces between the bars, but the image is still legible.

If you find any errors with the program or would like to see something changed, email me at dtolnay@hotmail.com and I'll try to fix it.
