Another solution, this one without any loops:
local $/ = undef;
$data = <DATA>;
# my @results = $data =~ m/First Line\nSecond Line\n(\d+)\n/mg;
# The m modifier was not really necessary here
my @results = $data =~ m/First Line\nSecond Line\n(\d+)\n/g;
print join "\n", @results;
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
