As mentioned in your other thread, probably the easiest way is to use the macro recorder. You can then access the code for modification in the VBA editor (alt-F11 or in the Macro submenu).

Even then, you might end up needing to use the open and input # statements to access the file the way you want. It's not the kind of programming I normally do, so I'm not real good at it. As I said, I usually use the data import command and extract the data after it's imported. I'm usually not one to try to do it all in a single step.
