Specifically, I save data from other apps as comma separated values and surround each line with {} characters terminating lines with a ,. Then adding a { at the beginning and a } at the end allows the entire file to be read into a Mathematica variable using Get. With this structure, it is a simple matter to add comments any where in the file separating them with (* and *). Mathematica will ignore these when the file is read using Get. This structure allows me to easily look at the data files with a text editor to see what they contain. In addition, I've created a couple of functions to use within Mathematica that allow me to read just the comments or append comments to any text file. If there is interest, I will post those here. -- To reply via email subtract one hundred and four
