in reply to Problem while refactoring code into a subroutine (was: subroutines!!!)

Instead of:

$dna[$i]

You want:

$dna->[$i]

Since $dna and $complement are array references, you need the arrow to de-reference back to the underlying array.

    If i wanted to return two arrays instead of one; e.g. 
    
return (\@array, \@array2);

    What is the syntax to using these arrays once they have been returned?? cheers

      You do exactly the same thing. The values you get back will be array references so you access the elements using the -> syntax.
