Double thread posting? Please try to avoid this, thanks. Someone will answer you if you're patient enough.

For lists, you might want to use binary blobs, like Data(1,2,3,4,5)->L1, which IIRC will store 5 bytes in L1.

You can access the data by using {L1+index}->whatever
Index is the position in the array; it can be a variable or a constant. If it is 0, you get the first element, if it is 1 you get the second element etc.
To store sth in the array, use the syntax the other way round: whatever->{L1+index}
