 Example 2 

Well, first try the YN.COM. Notice the bug, press 'N' or 'n' and the
program answers 'yes', press 'Y' or 'y' and the program answers 'no'.

Read the script file, compile it and run it.

Try the YN.COM again.

So what have we learned, we can solve bugs in the software and distribute
the .COM patch file so that not the hole package has to distribute again.
