comment Is it possible to change the color of plot in Show?
Thank you very much! You're so clever! But I found an easier way inspired by your idea. A single line Show[p/._Hue->Red] will be enough!

@image_doctor Thank you, Image_doctor! I know what you mean, ,I actually want the input process more intuitive. I have edited my question to make myself clear.

@JoelKlein n is also dependant on specific question. But it won't vary within the same question. What I want to do is actually a plot on a zigzag line, and r[i] represent the turning point

@Nasser Hi! Nasser. Thank you for your suggestion. But you leave a sentence without any further explanation. And I don't know why my way of typing input is not proper. The "r[i]" represents coordinate, when doing a specific calculation, I have to input initial coordinate manually one by one according to real situations. I can't find a better way to do it. Could you suggest a better way for me?

comment how can I generate a sequence of assignments?
Yeah! That's exactly what I want. I have more questions. First, why there is ToString before i ? I found that it also works without ToString. Second, why there is two RowBox? I found that with only one RowBox, that is to write like RowBox[{"r", "[", i, "]", "="}], will give result with a colored left bracket. Though the colored left brackets seems harmless, because I can set values normally. But I still curious about it. And finally both you and Nasser point it out that my way of input is not good. I leave a message for Nasser, would you take a look at it?

Right answer! Thank you very much! It seems that I need to update to mathematica 9 as soon as possible.
