in reply to "Or" in Array
use strict; use warnings; my @one = qw(5 6 7); my @two = qw(1 2 0); my @three = qw(1 1 1); my @four = qw(9 4 6); for my $i (0 .. $#one) { unless ($one[$i] and $two[$i] and $three[$i] and $four[$i]) { print "row $i has a zero\n"; # execute some code } }
prints:
row 2 has a zero
Update: You should consider reorganizing your data as an ARRAYS OF ARRAYS structure, if you have control over your data. In general, it is easier passing around one data structure than 4.
