my @LINES; while (<DATA>) { chomp; push @LINES, $_; } equivalent to this:

chomp (my @lines = <DATA>);

Who knows how that works, but it does. It's a perl idiom you need to know.

As for this:
my $split; for (@LINES) { my @row = split ('&', $_);

The only variable name you could think of, $split, is the same name as the perl function split() ? Don't ever do that. If you can't think up 10 unique variable names, you cannot be a computer programmer. Also, your variable names need to be descriptive. "Hey, Joe! I've got an array ref named '$split'. Guess what's in the array? Joe: Gold coins?"

Avoid writing $_ in your code. I suggest you read "Learning Perl 6th ed.". You need to learn modern perl.
