in reply to Sorting The Date format Values without using any perl modules.

Pray, please tell us why you are not allowed to use any modules or the split function?

I can understand that in some companies you are not allowed to install any odd module on your system, but not using a built-in function? It is like saying: "please add this list of figures but don't use +!"

    No + or =

    sub add_em {
    my $sum;
    for (@_) {
        for (1..$_) {
          $sum--;
        }
    }
    return -$sum;
}
print add_em(1..5);
