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";
}
prints
d
e
f
If you need something more general, speak up.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
