hi. i havent been learning perl for a while and i forgot a lot. so it may be easy question, sorry for that. my problem is, i am creating a 8000x8000 2 dimensional array. there are some proteins, if they interact, their corresponding value will be 1, otherwise 0. interacting proteins are given pairwise in a tab delimited text row by row. so i have thought of something like this; 
 $/ = undef;
my $string = <IN>;

my @all = split /\t|\n/,$string;
my @array;

for ($i=0; $i<$#all; $i+=2)

{    $array[$all[$i]] [$all[$i+1]] = 1 ; 
    $array[$all[$i+1]] [$all[$i]] = 1 ;
}

so my question is, how can i use strings in an array bracket. like $array [ proteinA ] [ proteinB ] if i am not wrong, it is possible without using "strict". code will be used just a couple of times, so easier way is better. i would also like to hear, if there are some other ways. thanks for reading.
