I do have Excel 2007, but I have been unsuccessful in using it to
effectively create a fixed-column file. Whenever I save the file as a
.prn, I only get about 250 columns. But this is Statalist, not
"Excellist"....
Thanks to everyone for their suggestions. I am still working on it,
but I think one of these methods will likely work for me.
