On the other hand, Perl itself provides the ability to go through a file one line at a time, so you could just read a line, operate, write a line (to a new file) as needed, over and over, until you get through the whole file. The real problem would be reading the whole file into a variable (or even multiple variables) at once. -- CCD CopyWrite Chad Perrin [ http://ccd.apotheon.org ] Isaac Asimov: "Part of the inhumanity of the computer is that, once it is completely programmed and working smoothly, it is completely honest."
