Perl doesn't support the comma separated indices for multidimensional arrays. Instead of

$a[$i, 1]

use

$a[$i][1]
[download]

Update: Use warnings, Perl will tell you:

Multidimensional syntax $a[$i,1] not supported at ...
[download]

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

You can emulate multi-dimentional arrays with hashes though. It's a feature not many people use. `my %multidim; my $x = 3; my $y = 4; $multidim{ $x, $y } = 42; print $multidim{ $x, $y }, "\n";` [download] toby döt ink	[reply] [d/l]
