i see. so if my array @positions is already defined and created, do i need to loop over all the values in @positions and then execute the code you posted?

something like:

 for (@positions) {@positions = grep $_->[1] =~ /ac/i, @positions;}

and then:

 for (@positions) {@positions = map $_->[0], @positions;}
