By one definition, arrays in Perl are only one dimensional, so there is only one row (or column) to print.

For instance, examining a 2D array in the debugger gives:

DB<1> @x = ( [qw(a b c)], [qw(d e f)], [qw(g h i)]) DB<2> x @x 0 ARRAY(0x15d5240) 0 'a' 1 'b' 2 'c' 1 ARRAY(0x1cbe3f4) 0 'd' 1 'e' 2 'f' 2 ARRAY(0x1cbe430) 0 'g' 1 'h' 2 'i' DB<3>
This shows, for instance, that $x[0] is an array reference (ARRAY(0x15d5240)), and points to an array equivalent to qw(a b c).

To print a single row of a multidimensional array, you must first define which is the row index.

For the first index, this works:

my @x = ( [qw(a b c)], [qw(d e f)], [qw(g h i)]); my $row = 1; # print this row foreach my $col (0..$#{$x[$row]} ) { print "$x[$row][$col]\n"; }
d e f
If you need something more general, speak up.
