Perl Subroutines Call

[Anonymous Monk]

Hi,
I am a little confused with perl subroutines. Can anybody explains the differences in ways to call subroutines for me.

sub Test {
    my ($X,$Y) = @_;
    
    return "Hello $X and $Y\n";
}

print "With &\n";
print &Test('name 1','name 2');
print "Without &\n";
print Test('name 1','name 2');
print "Without brackets\n";
print Test 'name 1','name 2';

what is the best practice to use, when and why?
Thanks in advance
