### Rosetta Code example

# This is a code example in basic 256 that you can find in Rosetta code website http://rosettacode.org/wiki/Greyscale_bars/Display. There you will find this program (and more) in many other languages such as Java Python and C, and that is a very good way to learn new programming languages.
