If it is just an array and nothing else gets passed, then you can pass 
it normally...

my $return = passArrayToMe(@array)

and your definition will go something like this:

sub passArrayToMe {
   my @array = @_;
}

but if you need to pass other variables as well then you will need to 
pass an array reference, the reference being the key here, so:

my $return = passArrayRefToMe(\@array)

and the definition being:

sub passArrayRefToMe {
   my $arrayref = shift;
}

or

my $return = passArrayRefToMe($someVar, \@array, $someOtherVar);

definition like:

sub passArrayRefToMe {
   my @args = @_;
}

where args[0] is $someVar value
where args[1] is the reference to the @array
where args[2] is $someOtherVar value
