A full answer to this exercise is provided as part of the training course!

1)	Download the files needed to start this exercise: exercise-653.zip (and click here if you experience any problems unzipping this file after downloading it).
2)	Add the form shown contained in the folder shown above to your project.
3)	Use debugging to work out what the program does.  Remember: You can press F9 or click on the grey left margin of a line to set a breakpoint You can use F11 to step into a property or subroutine, or F10 to step over it You can use the immediate window to look at specific values
4)	Add statements like Debug.Indent and Debug.WriteLine to your code so that you get an answer something like this:
	Your immediate window definitely does not have to look exactly like this
5)	When you have finished, close down any open forms.

On all Wise Owl scheduled courses delegates can take away these model answers (together with their own efforts!) on a free USB stick.
