Read again what I explained about using prototypes.

The (\@$) prototype definition expects an array as its first argument and makes it into a reference (i.e. a scalar). So your 

my (@array_of_lines, $entry_no_new) = @_;

[download]
is quite wrong.

It should be 

my ($arrayref_of_lines, $entry_no_new) = @_;

[download]
and next you must dereference the reference: 
my @array_of_lines = @$arrayref_of_lines;

[download]

Trust me, you are far better off forgetting all about prototypes and simply use references.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
