you keep swapping hash and array concepts, words and symbols. please
learn to keep them separate or your perl life will be hell. hashes have
no concept of 'final value' as an array would. maybe you mean the hash
is finalized and won't be changed anymore. if so then say that.

hashes have no positions, just keys. again. try to use standard
terminology or you won't convey any proper meaning here. programming
requires this to be accurate. and yes, you have been making a bunch of
hash/array mistakes and you must fix that in your head. they are similar
in syntax styles in some ways (e.g. [] vs {}) but very different in
semantics and terminology.

It would also help to post the snippet of code that is causing you
problems. Include some data it is to work on (not real data, you don't
want to post real data on a public mailing list; create some typical but
fake data) and the output you want. There is no need to post the actual
output; that can be generated by running the code.

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
