If you are in the programming class you have a little "homework". For two weeks from yesterdays programming class (when we learned about karel) I will assume you have watched the following youtube video (or for that matter video 6 of this iTunes U series http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewiTunesUCollection?id=384232896#ls=1 ) It is a bit long, but once you watch this you will understand while, for, if, variables, order of operations, logic, et cetera clearly. This video will do a better job explaining all this than I could do. I know it is long, and it is not the most interesting thing, but it would be really great if all of us knew this and I could move on to bigger and better things next programming class (2 weeks from yesterday) If you are confused why there is no programming class next Tuesday, it is because we will be doing electrical stuff next Tuesday. http://www.youtube.com/watch?v=GPWah4wbwYs&feature=PlayList&p=84A56BC7F4A1F852&index=5 <http://www.youtube.com/watch?v=GPWah4wbwYs&feature=PlayList&p=84A56BC7F4A1F852&index=5>(that is the video you should watch ^^ ) -- »»Mark Amber««
