in reply to Storing an indeterminate number of hash keys in a variable

There's probably a better way to do it, but you could do something along the lines of:
my %test; $test{a}{b}{c}{d} = "Hi"; my @keys = qw( a b c d ); my $out; my $ref = \%test; for( @keys ){ if( ref $ref->{$_} eq 'HASH' ){ $ref = \%{$ref->{$_}}; } else{ $out = $ref->{$_}; } } print "$out\n";

marioroy I once fell asleep while drive and had no collection on how I exited the ramp. Then called my wife not knowing where I was totally lost.
