FILEOUT is opened to append (this is indicated by the >>. The name of the file is maillist.txt. The error line will catch problems opening the file. The record that is written to the file contains all of the fields that were inputted on the html form and then stored in variables in this code.

This code reads the records on the maillist.txt file into @records.
I then process @records by going through each record individually using the foreach which establishes $record as an individual record from @records.
