Short answer: yes.
Long Answer: There are arrays can hold scalars; a reference to an array
is a scalar; therefore you can have an array of arrayrefs. Happily
there is a bit of syntatic sugar that lets you say
$array[0][4] = 10;
instad of
$array[0]->[4] = 10;
Note that this also lets you combine associative arrays (AKA hashes) and
arrays:
$control{'PCI'}[5]{'wanklefutzer'} = 10;
As you start messing with multidimensional data structures the
Data::Dumper module will become your friend. In the case above you
could say
print Dumper(\%control);
to find out what exactly is in the hash named control.
