Need Help??

Why make things overly complicated?

while (<DATA>) {
    next if !m/foo (\d+) bar (\d+)/ || $1 != $2;
    print;
}

__DATA__
foo 1000 bar 1000
foo 1000 bar 500

That can also be written using positive logic, as follows: `while (<DATA>) { print if m/foo (\d+) bar (\d+)/ && $1 == $2; } __DATA__ foo 1000 bar 1000 foo 1000 bar 500` [download]	[reply] [d/l]
