# Check the number of arguments on the command line:

};
# Check existence of the textfile and email listing file:
(open TXTLIST, "<$ARGV[0]") or die "unsub2sql.pl txtlist file $ARGV[0] not found.\n";
(open SQLOUT, ">$ARGV[1]") or die "unsub2sql.pl SQL file not made.\n";

  $email =~ s/'/\\'/g;  #Deal with O'Connor etc.
  $email =~ s/"//g;  #Deal with quotes around names.
