I have used two major methods of returning multiple values from a method.

First, if you know that the first n will be your array and the last will be a seperate value then you can use that when picking up your information.

#callMult returning an array and a scalar
my @ret = callMult();
my $foo = pop @ret;

However this code can become confusing. I prefer to handle this by returning references for structures.

sub callMult {
  return \@result, $count;
}

my ($result, $count) = callMult();

# you can then use
$result->[$i]; # to access the array elements
# or
@result_array = @$result; # to dereference it
