Dear every one
I have been looking at all your comments. please do not take what I wrote out of context. I still maintain that few lines of green comments may do more harm to a five statments program than good. I think that the % sign is very useful in long codes but not as much in short ones. In my case, I have included all explaination and an example in the pdf file I do not know how to do that with the % if any of you can teach me how to do it, I shall be grateful to him. Otherwise, he can try to be fair at least. Thanks to all

Dear Duane Hanselman
If you do not want the plot, you can close it or simply deactivate the plot command with %
Please go to the pdf file for instructions and help
