@records is just an ordered list. If you assigned to it directly, it would look something like:
my @records;
@records = qw( name ID email phone );
That means the 0th element is 'name', and the 3rd element is 'phone'. In code terms:
print "$records[0]\t$records[3]\n";
produces name phone. Does that help?
If you find accessing data by name instead of by index is easier, you can assign to a hash:
while (<DATA>) {
chomp;
my ($key, $value) = split;
$value =~ tr/"//d;
my %record;
$record{$key} = $value;
push @records, \%record;
}
You can then loop through records, printing just the elements you want:
foreach my $rec (@records) {
print "ID: $rec->{ID}\n";
print "Name: $rec->{name}\n";
}
Is that more clear?
