Workbook names in Excel 2007 are supposed to be limited in size only by memory, but this appears not to be the case. Eventually, an array saved to a name will get big enough that when you try to save you get (paraphrased): "one or more of the formulas in this workbook is larger than the 8192 character limit, please save as binary file"....
