Hallo, all!
I have a function which prints array:

my $array_ref = shift;
for(@$array_ref){
print $_\n;

And I have a big array, for example named @array.
I want to print @array elements from N to N+100 using this function, but

Erm... if you really don't need the array anymore, why don't you just
deflate it by splicing on itself?
@array = splice (@array, N, 100);

But this operation means copying an array? Even at return the result
from function.
And if the array and/or length are very big, it will take a long time

I'm sorry, as I can see I have explained incorrectly a problem.
In main() function I have an array (not the array reference).
But function print_array() takes a reference to a part of array.
I want to give to print_array() function a reference to a part of array.
Array and that part of array may
