Thread: Alphabetizing a file?

Another quick thing I need some assistance with is alphabetizing a file created from the program. So, the program will create a file like:

Namath Joe
Lugo Julio
Favre Brett
Jordan Michael

And I need to put the file in terms order of last name:

Favre Brett
Jordan Michael
Lugo Julio
Namath Joe

I can only store one line of data at a time though in the program.
