A very flexible, non-destructive one-liner.

my @a = qw[one two]; my @b = qw[three four five]; my @c = qw[six seven]; printf +('%-10s 'x3) .$/ , $a[$_]||'', $b[$_]||'', $c[$_]||'' for 0 .. ( sort{ $b<=>$a } ~~@a, ~~@b,~~@c)[0]; one three six two four seven five

Or generalized as a subroutine

#! perl -slw use strict; sub pa_columns{ my $fmt = shift; printf( ($fmt x @_).$/ , do { my $n=$_; map{ $_->[$n] || '' } @_; +} ) for 0 .. ( sort{ $b<=>$a } map{ $#$_ } @_ )[0]; } my @a = qw[one two]; my @b = qw[three four five]; my @c = qw[six seven]; pa_columns '%-10s ', \(@a, @b, @c); my @d = 1 .. 10; my @e = 'A' .. 'G'; print $/; pa_columns '%5.5s ', \(@d, @e, @a, @b, @c); __DATA__ C:\test>pa_cols one three six two four seven five 1 A one three six 2 B two four seven 3 C five 4 D 5 E 6 F 7 G 8 9 10

Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
