Hello,

what is the best way to pass an array to a sub routine,
IE.
my @fields = qw(one two three);

send_array(@fields);

sub send_array {
  my @ary = @_;
 # do stuff here....
}
is this the most effective way to pass an array to sub routine or is 
there a better way to do this.
That depends on how you define "effective".  The way you showed is the 
easiest.  References are probably better in some respects though, if 
you don't mind the complications:

my @array = qw(1 2 3);
my @other_array = qw(dog cat pig);
send_array([EMAIL PROTECTED], [EMAIL PROTECTED]);

sub send_array {
        my($nums, $anims) = @_;
        # do stuff with references here, for example
        print $nums->[1], ' ', $anims->[2], "\n";       # prints "2 pig"
}
Hope that helps.

James
