Files handling and lists

[gonzo620]

Once you read a file it's done. You read fin on line 2, putting it into data. So when you try to read it again on line 11, there's nothing left, and your loop to build the lists does nothing. The loop should probably be through data, not fin.

when I do the loop through data then an error happens with the integer commands. fout is supposed to remove the first line because it is the header so this error doesn't happen. and the last part of this code adds that header line back in. Any suggestions?
