Dear Monks,

The following code selects a few arrays from an AoA which will passed on as arguments to a subroutine.

It does work, but since I receive that AoA through an array reference from a previous sub, would there be a way to have the loop work directly on the arrayref instead of dereferencing the arrayref into a AoA?
use strict; use warnings; use Data::Dumper; my @AoA = ([10001, 2.71, 4], [160001, 123.4, 5], [170001, 234.9, 9], [ +670002, 44.8, 11]); # data structure actually received as ref my $AoAref = \@AoA; my ($arg1, $arg2, $arg3); # AoA is OK print Dumper ($AoAref); for my $i (0 .. $#AoA){ my $aref = $AoA[$i]; print "array is: $AoA[$i]\n"; $arg1 = $AoA[$i] if ($AoA[$i][0] == "160001"); $arg2 = $AoA[$i] if ($AoA[$i][0] == "170001"); $arg3 = $AoA[$i] if ($AoA[$i][0] == "670002"); } # Checking that got what is expected, OK print "Ex.:argument1 $arg1\n"; print "argument deref @$arg1\n"; # Passing to &someothersub($arg1, $arg2, $arg3);
Any way (if possible elegant) to operate on AoAref directly?
for my $aref ( @$AoAref ) { print "\t [ @$aref ],"; # not exactly sure what i'm doing here... }
The Cookbook and perllol do not seem to address that specifically

Again all guidance and advice will be greatly appreciated

UpdateThanks to Ikegami for yet another masterful tutorial and to Util for also a very Perlish solution.
