I have a simple program that takes three lines of text from the user, joins them together to make one array and then tries to sort them. The program seems to work ok untill it reaches the sort function. The syntax looks fine so I don't know why it doesn't work. Any advise would be much appreaciated. Here is my code... Thanks 
main2();

sub main2{
print "Type first sentance: ";
chomp (my $sentence = lc<STDIN>);
print "\n";
my @words = split(" ", $sentence);  

print "Type second line: ";
chomp (my $sentence2 = lc<STDIN>);
print "\n";
my @words2 = split(" ", $sentence2);  

print "Type third line: ";
chomp (my $sentence3 = lc<STDIN>);
print "\n";
my @words3 = split(" ", $sentence3);  

my @string = join (" ",@words,@words2,@words3);  
print @string;

my @sortedwords = sort @string;
print "\n@sortedwords\n";

}
