Heh! % is VERY useful. I use it in my $DateXpander script to handle the leap years.

Anyhow, as far as adding files...
Do you want to add the number of files? Or all the numbers in a file? If the latter, how is the file formatted? If you give an example of the format of the file and how you want things added from within it, we can help with that. It's hard without an example to work with.
