in reply to index offset mean?

Perhaps this little sample script will demonstrate the definition.

$ perl -e ' my $string = "Lorem ipsum"; my @array = qw(The quick brown fox jumps over the lazy dog); for my $offset (0..length($string)) { printf "Offset $offset: %s\n", substr($string, $offset); } for my $offset (0..$#array) { printf "Offset $offset: %s\n", $array[$offset]; } ' Offset 0: Lorem ipsum Offset 1: orem ipsum Offset 2: rem ipsum Offset 3: em ipsum Offset 4: m ipsum Offset 5: ipsum Offset 6: ipsum Offset 7: psum Offset 8: sum Offset 9: um Offset 10: m Offset 11: Offset 0: The Offset 1: quick Offset 2: brown Offset 3: fox Offset 4: jumps Offset 5: over Offset 6: the Offset 7: lazy Offset 8: dog $

[1nickt]: my $x = $aohoaoh->[0]->{' foo'}->[0]->{'bar' }; should work
[thepkd]: not indexing
[thepkd]: getting data out of the ds
[choroba]: it depends. Give more details, please
[thepkd]: i used a series of {}'s but it dont work
[choroba]: You need square brackets for arrays
[GotToBTru]: you can certainly construct a single expression to access any part of the data structure, without using temp variables. but you might make it easier on yourself and any other poor soul who has to understand your code if you do
[thepkd]: to dereference i mean
LanX .oO( oh tempz, oh moretz)
[thepkd]: @GotToBTru Sure. But.
