Based on your example, what you really should have are 4 cells. You shouldn't try to load everything into a single cell. This approach, while convenient to a beginner, defeats many purposes and makes for difficult to understand Notebooks and code in the medium to long term. Your present approach of copy-and-pasting, perhaps into a new Notebook even, is highly recommended. On Mon, Jul 2, 2012 at 2:25 AM, Nasser M.
