in reply to Splitting arrays

It is probably a bad idea to split such closely related data into separate arrays. Use a hash of arrays.

my %location_data; foreach (@values) { my @vals = split /,/, $_; push @{$location_data{lat}}, $val[0]; push @{$location_data{lon}}, $val[1]; }

Depending on how you use the data, it may be more convenient to have an array of coordinate pairs. (Like you already have except each pair would be stored as a two element numeric array rather than as a string.

my @locations = [map {split /,/, $_]} @values;
