You should use warnings; Because the default for filehandle is *input*. So when you write open(FILE, "$S") you open the file for reading. You should have been warned about that.

@lines = <FILE> makes a copy of the file content, but for(@lines) doesn't make any copy, inside the for loop $_ is not a copy of a line, it's the line itself. So in the end @lines and @newlines are certainly the same.
